Q: - Help - Extended monitor and laptop monitor not working


Today I plugged an hdmi to vga cable into my Win 8 sony vaio, and I plugged the other VGA side of the cable into an acee 22" monitor. I then chose from the right hand windows 8 panel to "extend to monitor", the laptop screen went black, the monitor screen remained without signal (extended screen did not show on monitor) and now the laptop screen is black.

I am now stuck and both laptop and monitor screen not working.

I tried unplugging cable, pressing fn and all the f1 to f12, shift, windows button but nothing is working.

I pressed off button then switched laptop back on and it showed the sony vaio logo on laptop then the screen went black again.

Please tell me how could I return my laptop screen to work and stop the screen extension which is not working and which I am sure is the case.

Any buttons on keyboard to click at all?

Any solution is highly appreciated.

Thank you

It's stuck in an extended screen it seems, boot into Safe Mode while you have all external monitors unplugged - Your Display is probably set to a resolution too high for both the external monitor and the laptop monitor, so you'll have to try "Boot to VGA mode" and I don't know where that is in the Windows 8 Boot GUI, if it is even in there at all.
Here is is- There are several ways to get to that from the Boot screen:

I have acquired an HP Envy M6 laptop (AMD version with ATI graphics) and I want to do a factory reset on it so I can customize it for me. Problem is the screen is broke so I have been using it with an external monitor until I can order the replacement screen. Problem I am running into is the extended monitor will not show BIOS screens or any of the recovery screens because no signal is directed to the extended monitor until it gets into windows 8. Is there a way to make it show boot screens or any screens it cycles through prior to getting into windows?

The broke screen illuminates and occasionally shows some of the desktop at the very bottom but I cannot see anything that I need to. I would like to go ahead and reset it so when I get the new screen it will be ready to go. Thanks in advance.

Hi - I have recently acquired a new work computer with 1 widescreen Dell monitor (Dell E228WFPc 1680 x 1050, Monitor A) and my older 4:3 monitor (E178FPc 1024 x 768, Monitor B). The graphics card is a NVIDIA GeForce GT 620. I cannot get them both working at the same time on an extended display.

One is plugged into (excuse my slightly less-than-technical language here!) the 'main' monitor port and one has a VGA-DVI adapter.

When either monitor A or B is plugged into the main port without the other plugged in, they work fine.

When monitor A, the widescreen, is plugged into the main port and B is plugged in via the adapter, A works perfectly and the PC detects monitor B (if I set it to extend displays, programs open in that screen but I cannot see anything - the screen is completely black).

When B is plugged into the main port and A is on the adapter, B boots up normally until the point where I would usually see my Windows log in, when it goes black and I can only see and move the cursor.

I thought it would be a case of adjusting the screen res down so that they weren't so drastically different - in fact I'm still sure that would help but I can't get the smaller monitor B to let me do so and it doesn't seem to make a difference when widescreen monitor A is plugged into the main port with B in the other?

A:Extended display monitor problems with one widescreen and one 4:3 monitor?

That is usually normal. Try dragging a window over to the other monitor and see if it works.

Hi guys

I have read quite a few forums to try and find an answer to my problem, however everything I have found and tried has not worked. Please read bellow and see of anything pops into mind to help.

I am extending my display to a Dell monitor and the screen wont fit the monitor exactly. I have tried all possible resolution options as well as going into the Advanced settings for the monitors display settings with no success (changing the monitors screen refresh rate - only the 24Hz option works). I have not tried to alter any graphic card options etc and took a screen shot of what I think the graphics card is, just in case it helps.
Another issue which I have noticed is that when moving my mouse left and right from display to display, it gets "caught" at the bottom of the screen but not at the top. I know its from the positions that are set for display 1 and 2 in the display options menu - as in the screen shot. Is there anyway to overcome this? Because when I move the screens around it still gets caught because of the different sizes of the screens.

I have attached an image with a few screen shots of all settings I have been playing with as well as a picture of the problem (Screen2).

I am using a Acer TravelMate 5740G laptop and have attached image (Screen1) showing the graphics properties.
Dell 26" monitor

Could someone please assist in getting my screen to fit the monitor exactly?

I have an HP laptop and I have been running it with dual monitors. I finally decided to upgrade to Windows 7 and after I installed it I noticed that the built in monitor of my laptop looked strange and when I opened the display settings to change the screen resolution and set the external monitor as a separate monitor rather than a mirror I noticed that only one monitor was detected and it was the external one (Generic non-pnp monitor on standard VGA graphics adapter) and the built in monitor does NOT show up at all.

I've tried the detection button, in hopes that the computer would read the built in monitor and I could fix the problem. This did not help. I tried unplugging/replugging the external monitor to no avail. I tried restarting without the external monitor plugged in and it STILL reads the built in monitor as if it is the external one. Is there anyway to fix this? I have not tried re-installing the OS, not yet anyways.

Any suggestions ?

I am using a 22" screen for my primary screen and the laptop lid open for a secondary screen. The main screens resolution is 1680x1050, I can set it to anything I want and it's always using the full screen. The laptop screen on the other hand will only use the full screen if it's at 1400x1050 resolution (max for that screen, IBM Thinkpad T43). With the large 22" screen I have no trouble reading the screen at high resolutions, the screen is huge, with the little 14" screen though I have to strain to read the screen at 1400x1050.

The problem is when I set the laptop screen to anything lower than 1400x1050, it uses less of the screen. Preferrably I want it at 1280x1024 or 1024x768 (I dont know which I want yet as I can't see the freaking screen at that resolution). At 1280x1024 for instance the useable screen is just a box in the middle, so the "1280x1024" is still barely readable for me cause it's shrunk from full screen, plus it's just annoying only using a portion of the screen.

I have played with the ATI Control Center, the Thinkpad display settings and windows display settings and just cannot get this thing to go full screen at lower resolutions when docked and using the external monitor.

Anyway to resolve this?

If you can boot into safe mode on the CRT screen, right click on that screen and select PERSONALIZE and then you should see two boxes to represent your screens. Click IDENTIFY monitors so you know which is which and then using the drop down box, select the correct screen and make this your MAIN Monitor

Hi all,

I recently purchased an ASUS laptop running Win Vista Premium. It has ATI Radeon HD3470 graphics and runs an Intel Duo P8600 processor.

I am trying to use a BENQ FP202W 20" LCD screen as a second monitor using the VGA output of the laptop. The problem is I can't get the screen to run in native resolution of 1680x1050. The option just does not appear in Vista or in the ATI Catalyst Control Centre.

I've downloaded the latest drivers for the video card and the latest version of Catalyst Control as well as the latest BENQ monitor drivers and nothing has changed.

Has anyone had this problem and is there a solution or do I just live with what I have.

Thanks in advance.

This is a rather odd problem. I use an basic SVID wire to a three plug audio/video cable from my laptop into a 10 meter extension, then into the tv. When I click to extend my desktop, it dosn't recognize the television. If i unplug the extension cable and plug directly into the television, then I can extend my desktop and it works fine. After I have the desktop extended, I can plug back into the extension video/audio cable, and it remains extended. And still works fine. I assume I cant extend with the extension cable plugged in becuase the cable is to long for the information to pass through and return to the laptop fast enough to change the settings.
The issue is:
Sometimes when I drag something onto the television side, my desktop flips. MY laptop screen appears on the television and my television screen appears on my laptop. My mouse also flips to the other screen, but though i see it on the television, its actually on the laptop side. If i click on the laptop side I will click on things that i see on the television side. If I click on sometime on the television side, instead it clicks on something on the laptop's side. If I log out, and log back in, my screens are flipped back around, but then I have to extend my desktop again.

Hi there,

I found a small 16 inch LCD tv laying around, which I want to use as an extended display.
My graphics card (GTX 285 Black Edition) as 2 DVI-I outputs, one already in use for my 24" Dell screen, so I bought a DVI to HDMI cable.
Now, my screen extends with it, but not on the way it should.
2/3 of the screen in height is displaying great, but the bottom section does not.
the left side (about 2/3 of the width of the screen) displays the right side, with a kind of green triangle over it, and the right side displays the left.
I included a picture, so you can see what I mean.

A:Extended Monitor Will Not Share Desk Top

Hi Reason, welcome to the Seven Forums.

There is no way you can use your laptop as a secondary display for your desktop simply by connecting it with VGA to your desktop. It does not work.

You can connect external display to a laptop to use multi display mode on laptop. If you want to use multiple displays on desktop, you need to use monitors or TV's equipped with VGA, DVI or HDMI. Laptop display is impossible to use as a secondary display for your desktop without some heavy tweaking.

Can I use my laptop display for my desktop?

With some restrictions, you can use laptop as a secondary display over the network. Here's how: Bits Bytes n' 42: Using the spare laptop as a secondary monitor.

Please keep in your mind this is not suitable for graphic intensive stuff:

Since the desktop is captured, streamed over the LAN and recreated at the destination end this is generally ideal for the static text windows. But it is quite acceptable for small sized videos as well.

I recently bought a DVI cable to plug my external LG monitor to my laptop to run nVidia's DualView (stretch format) across the two monitors. I'm using a beta driver (169.04 from laptopvideo2go.com), and when I enter nVidia control panel and go into the setup additional monitors tab, it only lets me choose "choose only ONE monitor". So I did that just to test that my monitor was plugged in right, and it worked. So I KNOW that my monitor is working and is being recognized by Vista. But when going into display settings byt right clicking on my desktop, it also only recognizes 1 monitor. Is it my beta display driver messing my Vista up? Or what could it be?
Any help would be greatly appreciated

I have a Genius GPen 4500 USB graphics tablet (using the built-in Windows 7 driver), and would like to use it on my secondary monitor (which is 4:3, unlike my primary which is 16:9)

However, windows seems to have decided that the tablet is integrated into my primary monitor (according to "Tablet PC Settings" in the control panel - it shows "Pen Input Avaliable" for the "1. BENQ E2220HD" item and "No Pen or Touch...." for the "2. SyncMaster" item)

Running "Setup" from that window does not work, as the tablet still maps to the primary screen, and can't be used to click on the second screen.

Is there any way (even a registry hack) to change which monitor is used? Or to update the range for the tablet such that it maps to the second screen.

If it helps, the setup is a classic horizontal setup (1920x1080 on the left, 1280x1024 on the right)

P.S. Sorry if this has been asked/answered before, but both googling and a search of the forum failed, but I may not have been using the correct terms)

A few days ago I was trying to get my tv to act as a monitor so that I could watch movies on it through my win7 PC. It kept showing up as a black screen with the cursor on it, or weird bits of my desktop, so as I was trying to get it to work I played around with my display settings and set extended display mode on.
Now, if I boot into windows regularly, it is just a black screen, and if I connect the TV and the monitor, the TV is a black screen and the monitor goes into sleep mode (no input). My display works fine in safe mode, and I have tried changing the safe mode resolution (which doesn't carry over) and using regedit to change the x/y resolution values for normal mode, but that did nothing. The most quirky thing is that if I try to boot into VGA mode my monitor also goes into sleep mode. If I use msconfig and choose to boot at base video, my safe mode resolution is appropriately 640x480, but if I try to boot normally, it is the same as if I used VGA mode (no input), I also cannot do a system restore (no save points).
I have an AMD Radeon HD 5670 graphics card and would greatly appreciate any help.

I extend my Tecra laptop to an external monitor and has worked fine until a couple of days ago where the monitor screen has suddenly started showing a red tint on the screen whereas my laptop screen has a normal colour on it.

I have tried 2 different monitors and 2 different VGA cables so it must be a problem with the display settings or hardware in the laptop. Anyone have an idea of why this is happening?

It is not easy to give you some concrete answer to your question. In my opinion this should be checked by Toshiba service provider.

Hello: I purchased a ZBook 15 G2 Mobile Workstation in February 2016 and noticed something I didn't expect with this computer.  When I play video on both screens the external screen is playing at 15fps.  I saw this with my older EliteBook but expected that it would be cured since the new one includes a video card.  I assumed that with a video card that both monitors could process video at the given frame rate. How do I make use of the video card or other setting to maximize the video playback quality (and other graphics) on the external monitor? Details: I have a ZBook 15 inch G2 Mobile Workstation with an NVIDIA Quadro K610M Graphics card, am running Windows 7, have 16 GB RAM and a 7200 RPM hard drive.  I am using a VGA (XVGA) output.  I believe there is also a thunderbolt 2 output. I am using a software called TrialDirector that utilizes Windows Media Player.  The video is playing on both screens, but the screens are set in Extended Screen mode.  The software mirrors the video onto both screens. There must be a way to set the onboard screen to run from the onboard graphics and the external to run from the card. Thanks in advance.

First of all, I highly appreciate any help I can get through these forums. My problem is so stressful that anything would be good atm.

Ok, so my problem:

I can't get extended desktop to work since I have Windows7. It allways worked flawlessly on windowsXP pro and I used it on windows7 aswell for a little while.
But all of the sudden my second monitor won't boot from hibernation correctly anymore.
When I turn on extended desktop, my second monitor will boot and everything seems to be working perfectly, but unfortunately this only lasts for a couple of seconds before the monitor goes to black again. Windows still sees it as a working monitor and I can drag stuff on that screen.

There's a huge list what i've tried allready:
- Changing monitors and cables ( tried 3 ).
- Dual-link and single-link DVI connectors.
- Updating ATI drivers from 9.7 up till 10.9 ( current )
- Format windows 7
- Checking resolution and hertz
- Replacing the PSU ( old one died, new psu has 200Watt more and runs on 700 and should be enough )

From this point on I contacted a Club3D tech:
- Bios flash to latest version
- Motherboard chipset drivers updated
- Clear CMOS

The Club3D tech analysed the problem and thought it was a timing issue in the graphics card and told me to send it in for repairs.

The card has been tested on:

Hi, so I'm having an issue with a monitor that I'm trying to do extended display with. I suspect the issue is with my computer because I can do dual view or duplicate display with the second monitor but not extended display though from what I've seen on youtube and forums I should be able to do it. I've updated my drivers for my graphics card but it doesn't seem to be issue. I've been doing a web crawl to see if my graphics card is compatible with an extended display setup but also no specific answers although I don't see why not. My cousin has virtually the same computer and computer specs I have and has been able to do it so I don't see why there should be an issue.

A:Problems with Extended Display/Desktop Monitor

Read other 16 answers

This is a strange problem...

My secondary monitor automatically dims itself unless I engage it either by pulling up the context menu or clicking a window. Simply bringing my mouse into its area doesn't brighten it, and it automatically dims as soon as I finish a task on that monitor.

Say I open a text document, click save and close it, as soon as the document closes the monitor dims.

I've searched around my video card's driver and firmware and I can find nothing, but I suspect this is a feature of said card.

Any ideas?

I have read this post: Generic Non-Pnp Monitor problem please help

and it seems similar to my problem but not quite the same. Before I proceed, I wanted to ask if the above solution will likely work for my problem.

I have an hp pavilion pc windows 7 with a radeon 5770, connected to two displays. I started up the computer about 4 months ago. The two displays are:

1)a pioneer vsx 1020 a/v receiver (in turn connected to my toshiba hdtv) via hdmi

2)an old (2001 or so) acer 1916 monitor

Everything was working fine for a while. I could control music selection (pandora) on the acer monitor while just having the a/v receiver on and not the hdtv, and it would be in dual display mode (both hdtv and monitor would default to 1280X1024 resolution---lowest resolution between the pair). Or I could extend displays and view hdtv in full ~1920X1000 hd resolution. When I chose extended display settings, it would recognize the acer monitor and recommend the correct resolution per this image: http://www.greenandtheblue.com/homet...desktop_PC.png.

Just a few days ago, I turned on the a/v receiver and the acer monitor (without turning on the hdtv) and the display was just the background and the resolution was too large on the acer monitor. I checked devices and now it shows "generic non pnp monitor". Also, in the catalyst control center settings, it shows the correct monitor (whereas windows config shows generic pnp) but it shows max reported res as 1600 X 1200 which is not ... Read more

A:generic non pnp monitor/extended display problem

I found a solution...first I reinstalled the hp monitor drivers under the hp recovery manager GUI. Then, no sound was coming, so I put default to both ATI Radeon and Realtec sound devices instead of just ATI or just Radeon which was the case when I checked. No idea what happened except maybe HP installed some updates and they wiped out the old monitor driver settings.

I currently have a 15" PC with a 3200x1800 resolution. Using Windows 8.1. I have the scaling to highest.

My 2nd external monitor is 1920 x 1200.

I am trying to extend my desktop to the 2nd monitor but is there a way to use different scaling for both the PC and monitor?

I have unchecked "use scaling for all my displays" but no matter what, I still can't change the scaling on the external display. It uses the scaling settings of my PC (scaling set to highest because of 3200x1800 resolution) and because of that, the monitor scaling shows everything large.

Thank you.

I worked with 2 monitor displays attached to my PC extending the desktop view across both, but one of them has broke, now only using one display I have an annoying issue that my desktop workspace still appears to be extended, and as such certain pop ups from programs I use are still appearing in the extended area which I can no longer use.

The display/ screen resolution options with Win 7 seem very limited I cant work out how to get around this

A:2nd 2nd monitor broke but cant disabale extended desktop

I've just checked again running my mouse pointer around the edge of the screen it is not extended anymore (I uninstalled the broken monitor drivers and rebooted) but I still have the issue with the program option pop up menus not appearing in my screen (I have to just press the ENTER key to close the options or the program locks up). I'm feeling I may have to re install the software I guess

We have an Optiplex 7440 AIO that needs to be setup as a tutorial PC in a teaching space.  There are also two projectors that display the image on the wall.  Both of the 7440 video outputs consisting of one HDMI and one DP (which is converted to HDMI) are delivered down to a Crestron switcher which pushes the output to the 2 projectors via a different topology.  
The actual configuration is a little more complicated than this, but I have simplified to the above configuration in order to troubleshoot.
Now what we need is to have a clone of the main 7440 screen on one projector and the 2nd projector having an extension of the desktop so they can display extra charts/windows.  When going into Windows Display settings, all three screens are detected and are in an extended state which is all good. When attempting to modify the setup and clone the 7440 image with either screen 2 or screen 3, an error is reported "Unable to save display settings".
I have updated the video driver to (A08) and also BIOS 1.7.6, but the problem still exists.
Is it possible to have a mix of extended and cloned displays such as this on this model?
Looking forward to your reply

I need some advice.

While attempting to clean out my husband's fan on his laptop, I think I may have disconnected the monitor?

I have cleaned it out before without much issue but this time I was having trouble taking the plastic housing off to get access to the fan. I finally got it separated enough that I could clean it.

However, once I turned the laptop on, I hear it powering up, but the screen is completely black.

I assume I may have disconnected the ribbon? Any ideas?

I want to open it back up and look but am a little fearful now. I want to know where I should look before diving in.

He has a Compaq Persario F700 series.

I have an HP Pavilion ze5170 which has many problems, but usually runs ok. I found out the other day that I have that worm on it that closes the task manager, msconfig, etc. I began trying to fix it, and at one point I had to reboot a few times. When I did, my monitor on it never came back on. I have no idea what happened, but another weird thing is that the onboard soundcard started working just before the monitor went out (the soundcard hasn't worked in over a year).

Is my laptop possessed? I have pluged my desktop monitor into the back of my laptop and am able to use that just fine (I'm actually making this post from my laptop). But I would just like some suggestions on how to get my monitor working again.

Can you see anything at all on the monitor screen even very faintly? The combination of the Fn key plus another key can also toggle the display between monitors.

Hello all,
I have a Phillips 32" LCD (model # 32TA2800/98) that I connect my laptops to with a VGA cable. I usually had my Gateway NV53A (AMD Mobility Radeon HD 4200 series Graphics card) connected and I never had a problem. Recently I connected my Samsung to the monitor and again, had no problems. When I reconnect my gateway the PC detects the monitor but the monitor does not detect the PC. If I switch back to the Samsung it works fine. I have reset the TV to factory default the only way I know how (owners manual). I have unplugged the power cable to the TV for 10 min+. I have changed from a 14 pin VGA to a 15 pin. I have updated all drivers.


A:1 monitor (Phillips 32" flat screen), 2 laptops, only 1 laptop detected by monitor

It appears this one has got them all stumped. I really need help with this one and I am at a total loss. I would be forever in someones debt.

Could it be that the TV has a capacitor that holds the settings for an extended period of time? Maybe I should leave it unplugged for 24-48 hours?

I have a dell laptop that has 1920x1080 resolution. However, i connect it to an external monitor that has 1920x1200 resolution. Basically almost everything i do is on my external monitor which acts as my main primary screen. Thus i do sometimes open some windows or drag a window or so to the other screen like youtube etc to the laptop screen which is the secondary monitor.

My issue at the moment is everything is way too big on the laptop screen. I want to have 1920x1080 resolution but its way too big. I googled what is my resolution on it and it shows 1536 x 864. Can someone tell me how to change this to 1920x1080? I googled what is my resolution on the external monitor and it does show 1920x1200 which is correct.

My external monitor which is my main monitor is fine at the moment with the 1920x1200. Its windows 10 but im assuming this should be very similar to windows 7 to fix this issue?

I had posted this on the Monitor forum, but they said this is a Windows 10 issue and not a monitor issue.  When I disconnect the P2715Q from the laptop and start to use the laptop LCD, everything is OK. When I reconnect the P2715Q to the laptop, I notice font changes. In Windows 10 File Explorer the font in the left panel is larger than the right panel, and the fonts in Quicken are smaller. When I reboot the laptop, everything is back to normal on the P2715Q. Is this normal?  Is there a setting in Windows 10 that I need to make so I don't have to reboot when returning to use the P2715Q?

My old dell laptop L502x is a bit quirky and caused me to buy a desktop, however, i think it is still saveable. when i have it display to an external monitor via hdmi, it works 100% with no problems. however, when i use the monitor that is physically attached to the laptop, i will get a " A clock interrupt was not received on a secondary processor" BSOD. from what i've gathered over numerous crashes, i believe its a problem with the integrated graphics in the processor, since they are not used when outputting via hdmi. i could be wrong tho, any help is greatly appreciated.

Windows 10 laptop. I connect it to an external monitor and use hdmi cable. My external monitor is my main monitor. I use the laptop monitor as the secondary monitor. I extend the display.

My desktop icons are always on my external monitor desktop. I had moved the hdmi cable connected to my laptop i believe which caused all my icons from my external monitor to go on the laptop monitor. Also there is even spacing on all of the icons. Has anyone had this happened? I then clicked sort and then it rearranged so there is no spacing etc. However, i then noticed hey why are my icons on my laptop monitor and not my external monitor.

Does anyone know why this happened? When i open chrome and other programs, it does open up on my external monitor though which is my primary monitor. I believe i can just drag each of the icons on my desktop on my laptop screen to my external monitor. So just do this and that fixes the issue right? Or is there a way to have all the icons just move to the external monitor. The reason i ask this is in case the icons just suddenly move to the laptop screen again.
