Q: I connected an external display to my laptop now no internal

Hey guys, so i'm running B10074 on my laptop , and I connected my external display to it as well as my external keyboard and mouse at my desk so I could sit there and do the setup etc without moving all of that out of the way. I had the laptop lid shut and off to the side while I was doing this. Then, I shut the laptop down, unplugged all the external peripherals, and turned it on again. It went through the windows boot sequence with the spinning circles, then black screen. After 20 minutes of frustration, I realised that the laptop would show a login prompt only when I plug in the external monitor BEFORE i start it, and only if the laptop is closed while it is booting (when the lid is closed during boot, the Dell logo and spinning circles come up on the external display)

I further figured out that in Control Panel, it only displays the external display, its like the computer doesn't even recognise the internal display anymore. I dont know why that would be since when I first booted it up and installed drivers, I was using the internal display and everything was working fine.
Any help appreciated as well as pointers on not running into this again

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Everything is fine when connected - then I close lid on laptop and the external screen becomes the main screen (with toolbar etc).

Already checked power options to make sure it?s set to, ?do nothing? when close lid but the problem persists.

Done some googling which suggests editing registry to ?lidalwaysopen? but that didn?t help either.

Any other suggestions?

Hi Forum!

I have a HP Pavilion dm1z laptop. The laptop has a HDMI port. I am trying to connect it to my Samsung BX2335 display. The display has the DVI dual link port only. So I bought a HDMI - DVI adapter.
I have Win7 x64 on my laptop.
When I start the laptop with the external display connected, the picture is duplicated on both the laptop and the external display. But as soon as Windows starts, the picture will only be displayed on the laptop, 'Starting Windows' being the last picture shown on both displays.
After some investigation it seems that windows could not detect the external display successfully. In the 'Screen Resolution' window the external display is shown as 'Display the device on: VGA'.
It is impossible to view the properties of the external display, as the option is disabled, and the display is called 'Default Monitor'.
I tried updating the AMD Radeon Catalyst drivers, but this did not help. Tried to install the external display drivers, but these installed as the mobile device display drivers.

Any ideas to fix this are highly appreciated

Hi guys,

One of my laptops is an old Acer Aspire 5610. I want to have a dual boot system, 7 and XP, but 7 on the internal HDD and XP on the external USB-IDE HDD, and by that, I mean a 100GB IDE Hard disk placed into a HDD enclosure, connected to the computer through USB. It also has separate power supply.

The internal notebook's HDD is also IDE.

I have read that installing Windows on external USB-IDE hard disk may be possible, depending on my Mainboard configuration. I have already checked my configs and it *does* support USB-IDE boot up to be first priority.

Anyway, since testing it would be really time consuming (to try to dual boot, and if failed, roll back everything) I want to ask your opinions, do you think is that even possible?!

A:Dual boot 7 (on internal hdd) and XP (on external USB connected IDE)


For it, you need not to change the boot order, too. When you want to boot from the external, reboot with the external HDD connected, and use the BIOS boot menu key to select the external HDD to boot from.

I have a Dell XPS L521x with Intel 4000 graphics as well as Nvidia GeForce GT640M. I currently only have one external display using the display port and I want to get a 2nd external monitor but I'm not sure if I can. I have read elsewhere that Intel 4000 graphics only supports up to two displays whether or not one of those is the internal display. So since I have a dedicated graphics card am I able to go up to go up another display? If you need more information let me know. Thanks!

For 6 weeks I have had no problems driving my 30" dell from the W520 displayport at its native 2560x1600 as the single "projector" display. Today, I aroused the laptop from sleep as usual, and was greeted with a blank Monitor and the laptops internal display on, with a fixed unchangeable resolution of 640x480. after about 5 reboots (includring removing power and battery), I found a way to get the W520 panel back to 1080p,but it wont display anything on the external monitor.  The monitor works fine connected to the displayport of my dell laptop, so I dont think its anything to do with the monitor. Interestingly, If I have the monitor plugged in, and do "Detect Displays" in he windows Display->Screen Resolutoin dialogue, I get this: 1.

My Thinkpad Yoga 15 has a problem, which may or may not be related to the BIOS update recently performed. When booting, the bootup screen only appears on an external monitor via the HDMI output. When performing the hardware tests in the BIOS, tests are done on the HDMI-connected display, the internal display does not seem to be recognized. I verified this using both Linux and Windows. It does not seem to be a hardware failure; I have been able to get the display on the internal LCD a few times, by powering down the laptop, holding the power button for about 20 seconds, then powering back on while pressing F1. The laptop will then function for a while, but loses its display after coming out of sleep. Needless to say, this is unworkable. Does anyone have any tips on how this could be fixed in a more permanent fashion or any indication to cause? BIOS does not allow me to turn off NVIDIA, or its opposite, to enable it exclusively. I also tried different drivers, from both Lenovo as well as NVIDIA and Intel, but to no avail. Any pointers appreciated.

Well, running w7 ultimate on a Dell xps m1330 laptop. Everything looks good, but at work I am connected to a matrox triple-head-to-go device which is connected to (3) 22' monitors (3840x1280 resolution). Now when I connected it, ran the nvidia app, it found it and worked great.

Problem is I get home, no external connected, so running off the laptop with the basic resolution, I am trying to start apps (firefox, stickies, etc.) and I guess they were in other spots at work as I don't see them. I forced a close on FF, then re-started, rt clicking and maximizing which worked, but then other apps like stickies don't have that option. An alt-tab shows it running in the lower right (see screenshot), but there is absolutely no way of getting to the app! I did close the app completely and restarted, but it does restart in a location not on the screen.

Any ideas or suggestions are appreciated.

Hi, I am using the default settings in the Power and Sleep settings. The notebook is plugged in to AC Power. It is plugged into the thunderbolt docking station with mouse, keyboard and ethernet connected. The display is supposed to turn off after 10 minutes and the computer is supposed to sleep after 30 minutes of idle time. It I do not connect an external display, everthing works fine. If I connect an HP27sv monitor to an HP DVI-to-DisplayPort adapter, and plug that into the docking station, then I get the following behavior. After a reboot, everthing works fine up till the first time the computer sleeps: The display turns off after 10 mintues and wakes up fine. After 30 minutes the computer goes to sleep.  However, once the computer has woken up from sleep mode, then it always goes back to sleep after two minutes. No matter what I do with the Power and sleep settings the computer goes to sleep after two minutes of idle time. I can also reproduce the bug using the sleep button on the keyboard: Connect external display Press sleep button on keyboard, computer goes to sleep Wake up computer and sign in Wait two minutes with no activity, computer goes to sleep again (should be 30 minute wait) This system has the NVidia Quadro M1000M display adapter for the docking station display ports. NVidia driver version is 354.86

I want to clone the internal 10gig drive on my HP Pavilion notebook to an external USB Iomega 40gig Hard Drive.

I have read that I can use Norton Ghost to do this, but can I clone the eentire drive (OS and all?) onto a partition on the external using Ghost?

Since the new drive is much larger, I'd like to clone the existing system in toto to a partition which will go untouched, then add data backups, downloads, etc. to other partitions on the Iomega HDD 40GB.

When I look at Norton's online documentation, it doesn't indicate whether this can be done.

I've also read that Ghost can be a bit daunting for the everyday user. I'm not a computer idiot, but also not a superwhiz. Are there other, more user-friendly programs that can do this? I have looked at Nova Backup site but understand that I need to use a program outside of Windows if I want a truly complete clone.

Thanks for any help you can give me!

Hi all, hope everyone is doing good?

Basically, I have a custom built pc back in the UK which I will be taking apart, as Im selling up everything I have back in the UK. (Moved to Finland last year from UK).

I want to keep my internal 300GB HDD from my custom built PC, and know I can do this, and also know what case I'm going for too, although it will be powered independently, with its own psu rather than USB powered.

Now my question is to you kind people, is, what exactly do I have to do before I can dismantle my custom built PC, and start using the 300GB HDD as an external HDD with my laptop.?

Im sure its not as simple as it sounds.? Just unplug, and fit to external case/housing(which comes with leads etc), and then use with laptop.?

Do I need to install anything on this drive so that everything stored on it can be accessible?

Also, not sure whats installed on there all together right now, although theres loads of photos, and files I need for work etc. My concerns are that some, if not all of the files used from the OS from my custom built pc are in there, which I do not need.

I will of course power up the pc to double check all files etc prior to dismantling, I just need some advice on what is the right way in going about this? The last thing I want to do is remove the 300GB HDD, then then bring it to Finland, and not being able to access anything due to some problems which could of been prevented back in the UK.

I have a Toshiba satellite a500.

The display stopped working about a week ago, and had not shown any previous signs of failing before then. I simply shut it down, and the next time it turned it on the screen had no display.

It can't detect it's LCD screen in any display options, and all brightness options have disappeared, as if it doesn't exist at all. There's no display on the screen, but other than that it still runs normally. For now, the laptop is only detecting the external monitor I have connected, which it designates as the primary display, rather than a secondary one.

However, I'm positive that it's not a hardware failure (for a weird reason I won't go into..), any advice on how to fix this, assuming that the problem is that the laptop isn't detecting the internal display? ( and not that it's a loose cable or a faulty screen..)

A:LENOVO Flex 2 14" - screen remains dark - When external LCD connected through HMDI , display shows.

Hi RDATA34 , 
Welcome to the Community Forums. 
Try to access the BIOS by turning off the system and using the novo button (item 7 page 68) to turn on.
This should offer the Novo menu screen and operates outside windows. 
Pressing caps lock on and off would likewise respond and connecting to an external would produce display.
Such condition isolates the LCD as point of failure. 
You can reseat (unplug and replug the LCD cable page 60) or have the LCD panel tested with available service center to verify the integrity of the LCD unit itself.
Hope this help answer your query. 
Update us how it goes.

This happens as soon as the VGA adapter is plugged in. Unplugging it does not turn the laptop screen back on. Toggling with the function keys does nothing. Since I cannot see anything I cannot try to adjust/correct display settings (or do anything for that matter, other than turn the laptop off by holding power key down).

The second display works (tested with a different laptop).

History: The external display worked fine with this laptop. We had a power failure yesterday which turned it off. The screen toggled to the laptop successfully (or I did, with the function keys--I don't remember) and I continued working. When power returned I started running into this issue. I reinstalled the display drivers from the original manufacturer disc but the problem persists.

To shut down properly hit the Winkey, then the right arrow, then Enter.

This may be as simple as capacitors overcharged. Shut down, unplug, remove battery. Hold power button down for 20 secs.
Do same for monitor.

So here's my problem.
I have an M2105 emachines notebook (laptop) and it's about six years old.

It works great but it's definitely time to do a reset with the restore CD's provided and start fresh. So I backed up all my important stuff and prepared for the big wipe.

My problem is that the laptop's original CD/DVD drive (Slimtype COMBO LSC-24082K) stopped functioning properly about two years ago. I didn't really use it much so I didn't care.

So it didn't surprise me when I put my restore CD in and it didn't work. So I went to Future Shop and bought a Samsung Slim External DVD Writer to compensate. It installed perfectly and it reads discs so I thought my problems were over.

I went into device manager and disabled the old Slimtype COMBO drive and even uninstalled it. I rebooted and the restore process began with the warnings (this will delete everything, are you sure? Press Y or N.)... when I hit YES it says CDR101: Not ready reading drive R and was forced to abort.

I tried to google "CDR101: Not ready reading drive R" and didn't find a resolution for MY problem. I dug deeper and realized that the computer was still looking for the old drive for some reason, because it was "finding new hardware" and bringing it back to life.

I went into the BIOS and checked the boot sequence and it is indeed looking to boot from CD/DVD first - which is GOOD. However, it lists the Secondary Master as the old Slimtype COM... Read more

I'm writing this post because this was asked so many times over, but nobody seems to have come up with a good answer. People suggested some trials of paid programs, but that's not really an everyman solution. I don't know on how many machines my workaround will work, depends on the audio chip.

I'm going to tell you how to do this in foobar2000. My system is Win7.

0) I think that this will work only if you see something like this in your Playback devices (right-click windows audio icon & select from menu to launch it):

So if the headphone output is not "Ready" when nothing is plugged into it, you will maybe be able to use the HDMI output if you feel adventurous, or for that matter any output that you have. You possibly have no idea why I'm talking about that, but this will be clear after reading through the rest of my little manual.


1) download & install foobar2000 here: http://www.foobar2000.org/download
play around with it of you don't know the player.

2) download & install the latest ASIO4ALL here: http://www.asio4all.com/
leave all install options default.

3) download ASIO support for foobar2000: http://www.foobar2000.org/components/view/foo_out_asio
double-click it, fb2k will install it automatically.

I just reloaded a laptop with XP SP2. After reload, my laptop internal and external speakers don't produce any sound. I loaded the driver from the laptop manufacturers website. And everything appears to be set correctly and working from a systems view. However - no sound from PC on boot, application, or cd or dvd play.

In Control Panel/Sound and Audio
Hardware tab - Windows says the hardware is working OK
Volume tab - All mute buttons are off/unchecked. Volume is high on all componets - PC Speaker etc.

I've also removed the driver and reloaded it. still nothing.

Is there anything else I should try? I doubt it is the motherboard.....

A:No sound from internal or external speakers after XP reload on laptop

It may not be the correct driver. There are some cases that the OS wopuld not report any abnormalities but the driver may not be the exact driver you need. Identify the sound device you need ( you can use unknown device identifier for that ) and download the apropriate driver.

Also check the microphone socket incase something got stuck in there.

My ThinkPad T500 running 64-bit Windows 7 Professional Edition worked great on and off a mini docking station with 2 external monitors. The dual-display setup allowed me to have more desktop space; when needed, I can take the laptop off the docking station (following undocking steps) and use it anywhere. This convenience no longer holds after upgrading to Windows 10.

With the T500 in the docking station (LCD lid closed), I can use the dual-display setup as in Windows 7. However, after shut-down and remove the T500 off the docking station and the T500 laptop becomes unusable because its LCD display doesn't show anything after boot. (While booting the laptop's display shows the ThinkPad boot logo and then some DOS-mode boot messages and then the windows 10 logo and its dotted spinning wheel; after the initial boot the display went blank and the Windows 10 desktop doesn't come up.)

The only way to make the T500 laptop usable on its own is to go through a "preparation procedure" and here is how the procedure goes: While the T500 is on the docking station in the dual-display setup with the 2 external monitors, open the T500's lid and set its display as the main display and then select to disconnect the other 2 external displays (in the Settings -> System -> Display page); then , in the T500's LCD display, select the shut down. Once the T500 is properly powered off, remove it from the docking station and the T500 can work on its own as a laptop supposed to be. W... Read more

A friend gave me a broken laptop. Really broken - dvd drive ripped out, squawking hard disk and worst of all - shattered lcd. I found an old CD-ROM drive, bought a new 2.5" hard disk, added some more RAM and connected the VGA port to an external monitor and presto - new lapt...er...desktop computer! It's a Compaq X1005EA too, only a couple years old.

The laptop lcd is shattered and replacing it would cost too much. The video card is obviously fine since it's been used via an external monitor for the past 9 months. It looks as if the connectors to the lcd screen aren't broken; I've disconnected the power connector but when on, the still-in-place lcd shards light up in a lovely jagged acid rainbow, so at least that one works.

Here's my question - is there a way to connect a 2nd external monitor to this laptop, via an adapter (or combination of adapters) to the internal video card, in effect replacing the broken lcd screen? This would give me the sweet multi-monitor setup I crave.

Thanks in advance,

Hey guys,I've been a lurker on here for awhile now and finally decided to post. I have had my HP Pavilion laptop (Windows 7) for 3-4 years now and just recently decided to hook it up to an external monitor to help with home productivity (it's only a 13'' laptop so it was about time). I took my old desktop Dell monitor and plugged it to the laptop via the monitor's VGA cable. However, recently the external monitor (which I have designated as my main display) started flickering for no particular reason. I updated my driver and then googled this issue online. The only real answer I have found is a "grounding" issue that does not pertain to me since my laptop continues to flicker even when it is not plugged in to battery power.So, I went out to Best Buy and bought a new VGA cable thinking that perhaps the cable was old and needed to be replaced. Although the new cable initially seemed to fix the issue, the external monitor still flickers at times, sometimes every few minutes and at other times several times per minute.Now, I just purchased a new 23" HP external monitor and although the flickering is less frequent, it still continues. I tried using a power surge and separating the power outlets for each plug (i.e., the plug's of my laptop and the external monitor) but that didn't seem to do the trick. I also tried using an HDMI cable but to no avail. Also looked at the refresh rate and I can't go below 60 HZ for the external monitor, so I seem to be fine there. Both the laptop and... Read more

A:External Monitor Flickering When Connected to HP Laptop

What does no avail on the hdmi mean? It did not work or it still flickers? Do you have the laptop set to only put out to the external monitor or is the built-in display also being driven by the video card? In other words, how exactly do you have the display set up? I think you are saying you have both screen displaying an image? Are you extending to the external monitor or mirroring the built-in screen? I know the external is the primary monitor but how are you using the built-in display? I would think you would have the best luck setting it to display only to the external. The other constant in the equation is the electrical system. Have the monitors always been plugged into the same outlet? Monitors can be very sensitive to electrical anomalies. I see you use a "surge" (supressor) but the inexpensive ones do not really smooth out power; you have to use a ups/battery backup for that. Is the wall power outlet a 2-prong or a three prong? Have you tried moving the whole setup to another room or another location? Does the built-in screen ever flicker?

I have an external 4k UHD monitor connected to my HP 8470p laptop. (I project content only on external monitor and my laptop screen is off)

The settings on Windows 7 have been configured to turn off the display after 1min (my laptop is still on and never shut off or put to sleep).

After a min of leaving the system idle, my monitor screen turns off and immediately within a few seconds turns on, a blank screen appears and displays my input source (in my case would blink "Display Port" a couple of times). Then a few seconds later turns off. This keeps looping forever and my monitor never sleeps.

Is anyone else facing this issue or have faced previously and are aware of a fix?

A:External Monitor connected to Laptop does not turn off

hi welcome to the forum.

I think whats happening is the laptop is turning off the output to the screen but the monitor is trying to search for an input. maybe their is a setting in the monitor itself. a work around would be set a screensaver to blank then the screen would just be a black screen.

I have a monitor connected to my laptop (running Windows XP) because the display is much better than the laptop's screen. It works just fine except for 2 things.

1) When I use the command prompt, and I go into full screen mode, the monitor turns off. The laptop screen displays properly.

2) When viewing video in Windows Media Player, the laptop screen works fine, but the monitor doesn't display the video. It still shows the menus, controls, playlist, etc., but there is a blank black box where the picture should be.

Does anyone have an idea how to fix this?

I have a lenovo g500s touch laptop that I am trying to get to work with an external graphics card setup, but when I turn the computer on, the screen remains blank. I can hear the fans spin up, and the external PSU and GPU fans spin up also, but the computer won't boot, not even BIOS. The weird thing is that when I remove the 4gb RAM stick, and leave the 2gb one, the computer works, the graphics card is recognized and works as expected also, I just can't play some games on 2 gigs of RAM. Also, the computer works fine with the 6gb of ram as long as the gpu isnt plugged in. Here is my setup:

OS: Windows 10
GPU: Nvidia GTX 750 ti SC (2gb of VRAM)
RAM: one 2gb, and one 4gb
External Pcie adapter: http://m.banggood.com/Mini-PCI-E-Ve...al-Independent-Video-Card-Dock-p-1011222.html

Hi all,
I connected an external screen for testing a presentation (just a second monitor), and ticked presenter view, clicked extend desktop and then it correctly identified the monitors., but the resolution on the external was low. So I turned it up, and fiddled around a little, then suddenly my laptop screen went blank (probably after I clicked yes to something) amd only the external monitor now shows anything. In display settings it now suddenly has two of my external monitors, and not my laptop one listed...

Identifying them shows nothing on my laptop, and the screen being "1"

I really need it back to my laptop screen, as it's hard to do stuff when the laptop is 1m away from the screen! I'm writing this post like it...

So please help!

Edit: Oh and by the way, unplugging the screen gives No Signal, and nothing to the laptop

Edit 2: Somehow I made both monitors appear in the list again, but still only the external will display anything. If I choose my laptop screen and click extend to this, it asks me to keep changes, I say yes, then it greys out again

I am new to this forum and I am having some trouble with my laptop. My laptop screen was cracked, and my future brother in law removed the screen completely, and then connected an external monitor. Everything was working fine until he performed a full system restore because of a corrupted file. Now the screen goes black on start up. In safe mode a pop up states that the installation cannot be completed in safe mode and automatically restarts, putting me back at square one. Is this issue fixable or should I just throw it away?

I have an acer laptop/now desktop running Windows Vista Home Premium if it helps.

A:External monitor connected to laptop goes black after system restore

I don't have much time but this will help others. When does the display go black? After the standard BIOS post information when it goes to Windows? When do you get the error message?

I assume this may be a refresh rate problem but there's not enough info to go on.

I have a Compaq Presario CQ62-209WM Laptop and I have an issue that is probably not huge, but it is very annoying. I connect my laptop to an external monitor, pretty much all of the time. I use this monitor (a Dell E177fp) as my main display in an extended desktop form. I like using the external monitor as my main display, and it is very convenient to have two monitors, but unfortunately this same issue persists, and has been this way ever since I bought my computer: whenever I have my laptop plugged into the monitor and I reboot, my computer boots up, showing the Compaq BIOS screen on both screens as well as the starting windows screen on both screens. However, once it boots up to the Welcome screen, it shows the logon on my Main display, but then the monitor is disconnected. I then have to login, wait for Windows to load all its stuff up, then press the Windows key + P until it shows the "Extend" option. Then I have to go into the Screen Resolution settings and reset the external monitor as my main display. Now it's not like this is a huge problem, it's just that I have to do this EVERY time I reboot. So my question is, is there any way to make Windows 7 remember that the external monitor is the main display? It's just inconvenient to have to deal with this upon every reboot. Thanks in advance.

Thanks a LOT in advance.

I already read following thread and the answer given by win2Kpro's :


An enclosure such as this;


with this drive;


and a copy of Acronis True Image backup software should give you a fairly reasonable backup solution. If you want a little better drive I would use this one.

Recently my laptop, which is successfully connected to the wireless network, has failed to recognize shared folders on my desktop and the external hard drive connected to it. Laptop running 7, desktop running XP Pro. 2 days ago it was working fine. Yesterday it stopped working. I have made no changes that I can think of. All of the folders on the desktop and external drive that I want shared are set up for sharing. So, my question is, what do I need to do to again be able to read and write to these folders, especially the ones on the external hard drive. I believe the adjustment has to be made on the desktop, either in the network connections or the file sharing, but the laptop may need adjusted as well. I am not an advanced user and would appreciate any guidance anyone with expertise could give me.
Thanks in advance!!!

Weird problem. Transferring between the two internal hard drives is very slow and some times does the bursts speeds. But if I try transferring from EITHER of the internal drives to an external drive they transfer at their recommended speeds.

Raptor SATA 36Gb - OS
Maxtor SATA 500Gb - Storage
External Maxtor SATA 500Gb - Backup (USB 2.0)

Any ideas?


A:Internal HDD transfer slow. Internal HDD to External fast.

What are the speeds?

Toshiba a100

Just recently replaceced my screen

I've been given a faulty Toshiba laptop/notebook to look at. The problem is that when I switch on the power button, various lights come on, but there is no picture what-so-ever on the screen. There are no beeps either, so no idea what's causing it. I've tried connecting an external monitor (and yes I've pressed the fn + 5 keys to switch monitors), but that isn't recognising any video signal either.

You can hear the hard drive start to whir, but there is no continued chugging sound like you'd get if the o/s was continuing to load. As there's no picture, I can't tell if the BIOS is giving me any warnings, whcih is why the HDD doesn't sound lke it's still booting.

Any help please...

I was trying to configure my TV as an external display for my laptop, to clone it, but I couldn't get the laptop's VGA driver (Intel(R) GMA Driver for Mobile - "Display Devices") to detect the TV. I used an S-Video/RCA adapter and cable, which is the same I use in my ATI X1550 on my desktop, and it works fine. In the desktop, after I plug it, in the Catalyst Control Center a TV is shown at the "Display Manager" options, enabling me to use it.

Additionaly, the TV goes to a static when plugged to the laptop's S-Video.

Can somebody give me a help as to why my laptop isn't detecting the TV?

Thanks in advance.

A:Using TV as an external display for laptop

It won't "detect" the TV. Generally on laptops, all you need do is to connect the TV and then use one of the display "F" keys to toggle laptop, TV, or both. Nothing needs to be done with the driver.

A few months ago, my roommate had a extra LCD computer monitor laying around, So I would often plug it into my laptop and have two screens working at once. It was that simple, plug it in and it came right up on its own. I even was able to plug my laptop into his big screen HDTV and play starcraft on it.

So today I stopped at the store on my way home to pick up a cable to plug into my small LCD HDTV by samsung. I figured i'd plug it into my laptop and use 2 monitors again. Of course, its not that easy. I've been messing with this thing for hours.

When I go to PC mode on the TV, and have nothing plugged in, it says: "No signal detected". When I plug it into the laptop, the TV's screen goes blank. It no longer says no signal detected... but nothing is happening.

When I go to my Nvidia options, theres a section for dual display configuration. Only problem is, the only display it sees is the default laptop screen. Theres a option to scan for a second monitor, but it yields no results. I've rebooted 5+ times, and gone through every option and google search I could think of but nothing. I dont think its a bad cable, otherwise it would still say No Signal Detected.

But im sure it something completely simple that I overlooked....

Any and all advice/help will be greatly appreciated

I recently purchased a Studio 1558 laptop. The specs are below:
Processor: Intel (R) Core (TM) i7 CPU   Q 720 @ 1.60 GHZRAM: 6 GBSystem type: 64-bit operating systemATI Mobility Radeon HD 5470Sound - ATI High Definition Audio Device, IDT High Definition Audio CODECI have plugged in older Dell speakers that I used with my desktop. The sound works fine until I load a webpage, or load a folder etc and then sound will temporarily switch from my external speakers to my internal laptop speakers. This is quite annoying as it happens frequently and sometimes I blare my externals which can't be good if it keeps switching to my internals.
Can anyone recommend a fix? It would be greatly appreciated.
