Preferred Solution: No Display Output

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


Hi everyone.
I am recently having problem with my PC.
My PC in not showing output on monitor when i start the PC.
but after pushing the restart button the PC restarts and output is displayed.
i don't know what is the problem. See my system specs in profile.
sometimes i have to restart twice to bring output.
I have dual boot with Ubuntu and windows 7 ultimate, so I push restart when it reaches the grub menu.
My PC's boot up itself takes more than 25 seconds till it reaches grub menu.
Please can somebody help me?
even if someone have any idea about the problem please share.

I have searched the forums and was not able to find anything on this issue.


windows media player will not display any video on secondary screens. I have a computer hooked up to a network of display outputs and when i tried to show a video it would play on the computer but the outputs (which showed everything else on the screen just fine) would just have a blank area where the video was supposed to be playing. sound worked fine.

My found temp solution:

WMP will only play video on the primary display device, It will not even let me toggle in between display devices while WMP is running. If i change the display device to my secondary screen (main laptop screen is now blank) and reopen WMP the videos will work as they should.

full solution endstate: display video on both primary and secondary screens simultaneously.

other info: unfortunately, there is a class being taught with said computer using temp solution, so i am unable to get WMP version. it is on an XP machine.

all help is appreciated.


A:WMP multiple display output

If you have ATI Catalyst Control Advanced there is a place in the settings for the form of vidieo playback you want on a secondary display (same as 1st, full screen, etc.). There might/should be something very similar for Nvidia as well.

If not however or maybe in spite of these settings correctly set, it doesn't work and if there is no other problem its a video acceleration problem which you can force by going to Display settings/Settings/Advanced/Troubleshoot and set the hardware acceleration to about 50% first and restart the player and see if it works. If not, set it all the way off and it should work if your system is capable and has no other problem. You will lose some other minor functionality in the video subsystem so its only a temporary solution. Definitely see if the Control center settings solve the problem first.

All the lights and fans in my pc turn on. But the problem is there is no display and when I first turn it on it shuts down then turns on. This normally means it is a cpu error and my motherboard couldn?t agree more becuase it has the red cpu light. Any suggestions?

Hi guys,
I'm really stumped with this issue.
I recently dug out my oldish PC (I didn't have it for a year while at University) and on first boot up it was fine. Second boot as soon as it moves from BIOS to windows there is no video out signal. The worst part is I have the same problem booting in safe mode as well.

So first up I'll post the specifications of my PC

ASUS M3A32 MVP Deluxe Motherboard (No integrated graphics to test against GPU)

AMD Athlon 64 X2 5200+, 2.7GHz

EVGA GeForce 9600GT


750W PSU

So the story is. I dig it out and move it to my flat from home. Snag an old monitor off a mate. I go to install Windows 7 64 bit Professional over the top of my Windows Vista Home Premium.

Everything goes smoothly and the update has worked great.

I boot up my laptop and download AVG's free anti virus protection. Copy the installer across to my desktop, run the software and connect my ethernet cable when prompted to download the rest of the software. I'm prompted to restart and do so. And now i when it boots the OS it crashes. Hmm.

I manually restart the computer and try and boot in safe mode, it comes up with all the files that it loads and gets stuck at one named avgidseh.sys and stops loading.

After a while it reboots itself and i'm back to square one.

I've tried to restore to all points available and it comes up with an unspecified error code.

So i figure it might be a GPU problem and plug in a friends AMD/ATI 3450 i think it wa... Read more

Hi guys, I have a problem with my monitor output changing when I play games. I only have one monitor connected via hdmi to my video card. It's sli. It seems to be set as the only monitor in all the settings but for some reason if I start a game the display output changes so I have to pull the connector out and change it to the second connector for the display to work again. When I close the game, I have to switch it back.

I had this same problem back in Vista but somehow it stopped, I am running Windows 7 now.

Does anyone know how I can solve this? Thanks.

That's not a problem. The resolution is supposed to change when you start a game and it's working correctly.

hi everyone I have a M83 Tower (10AK) with a dGPU installed, and I have two monitors, one of which is connected to the iGPU, and the other is connected to the dGPU. I followed the instructions at https://pcsupport.lenovo.com/hk/en/solutions/ht062228 , but while it works fine windows, I can't get the boot menu. This is what happens when I turn on my M83:1. Both monitors power on, but remain blank.2. The monitor connected to the IGP turns on and displays the windows loading screen, but the monitor connected to the dGPU remains blank.3. The monitor connected to the IGP goes blank, while the monitor connected to the dGPU displays the windows lockscreen. As seen above, the lenovo splash screen is not displayed, which makes it harder to get into the BIOS or choose a temporary startup device, since I can't get to the boot menu. Any input will be appreciated. Thanks in advance!

My problem with the card is my S-Video/TV out was working fine with my Samsung HDTV until up to half a year ago or more. The S-V/TV output just stopped working, no signal, no windows logo when I boot up the computer, nothing. So I thought it could be the cable, but the cable works when I use my laptop to my HDTV with the same cable.

I also thought it could be my S-V/TV input on my HDTV, but that wasn't the issue either for it worked when I used the my laptop to hook up to my HDTV. In my ATI Display Settings screen (Catalyst Interface), the system does not recognize the S-V/TV output (its shaded) when before it did. So then I tried to hook up the DL DVI output on the Radeon to my HDTV with a Dual Link DL DVI-I Male Cable to ATI Component Video Adapter and set the necessary switch settings on the adapter to only enable the modes my HDTV supports (480i,480p,1080i). I hooked it up this way because my Samsung HDTV does not support computer signals with its DL DVI connector hence why I went the adapter route so with this I plug that in to my HDTV via its Component 1 inputs, and still a blank screen and I followed the instructions to the letter as to how to hook these up.

The weird thing is in the Catalyst ATI Display Settings when I am hooked up via DVI the card recognizes that, but I still can't get it to display an image on the HDTV even using custom resolutions such as 640x480i @ 30hz or 60hz, 640x480p @ 30hz or 60hz, 1776x1080i @ 30hz or 60hz or just using defau...

A:Display output to tv 1080p quality

Any PC that has any type of external display connector can handle 1080p. VGA might have been a problem since not all TVs accept VGA (and not always 1080p when they do), but DisplayPort and HDMI have supported 1080p since they were introduced on laptops around 2009.

We've got a couple hundered M920q devices in our environment and when plugging in two displays it looks like the Display Port is the default output; when we go into BIOS or BitLocker it defaults to the monitor plugged into Display Port.

Yeah, that's my issue in a nutshell. I've got an ATI card (HD3450) with latest CCC. Thing is, when i run cmd.exe and alt+enter (fullscreen) it, the monitor goes blank (disables) and the fullscreen is drawn at the tv (extended desktop / 2ndary display). This is hopefully something I've misconfigured in CCC. I'd appreciate any help.

1) When I turn my monitor off (to save on electricity) and then turn it on again the picture is gone (no display output at all) and there is a green screen. The only solution is then to unplug and re-plug the HDMI cable which restores the picture.

I have noticed it always seems to happen when a video is being watched online, but not necessarily every time. (eg. never noticed it with youtube) in particular I notice it happening with Amazon prime video. How can I stop this from happening?

I'm running Windows 7 Ultimate and Chrome. I thought maybe driver updates might eventually fix the problem but never did.

2) Additionally, if watching video full screen on some websites (eg. onlinemoviespro) when I click on the screen it sometimes suddenly exits full screen and at the same time makes the window small and I then have to re-maximise the window and go full screen. This doesn't seem to occur when not in full screen mode though.

Any theories/solutions? It only seems to happen with websites which use that specific web video player.

wht should i do???? could it be a power supply issue?? and shud i try removing the small coin like battery and if i shud,then wht happens when i remove that battery and how long is it to be removed for?

A:PC stopped booting up, no display output

What power supply is it? (company, model, wattage,)

Most low quality power supplies will have little or no transient filter, which filter the incoming AC power and suppresses any voltage spikes. Most of the time when the power is cut the voltage spikes a bit.

Try removing your CMOS battery and you suggested and leave it out for about 10 minutes, and make sure you psu is unplugged and discharged.

You can discharge it by pushing the power button immediately after you unplug it, the lights and fans should flash for a second, then go off.

Foolishly, I accidentally changed my display settings (right mouse click on desktop) from "Monitor" to "Digital Display" and now I cannot see anything!

Obviously, I dont have access to the desktop to change it back again, so wondering what my options are....

I can see the system boot up, display the windows logo, etc, but when it should show me the windows desktop, the monitor just goes black and i see nothing.

I can boot up in safe mood, and see the desktop, but not when i boot up normally. Is there anything I can change in "safe mode" that will enable me to change things back?

please help!!!

I resumed my PC from standby this morning, and the display output is now so dark, I can hardly see what's on the screen. I don't think the problem lies with the monitor (a new Hyandai 19" LCD) since the on screen controls are still bright and the VGA connection from my Mac still works fine. I have restarted the computer multiple times, as well as unplugged and replugged the DVI. I haven't yet tried using the VGA connection from the pc. I have an Abit IT7 mobo, P4 2.53, 512 MB, ATI 9700 Pro, Win XP SP2. Anyone have any idea what might be going on? My first thought was maybe the bad graphics card was going bad, but now I'm wondering whether the proble might be a bad mobo or RAM. Has anyone experienced anything like this?Thanks for any help you can provide!

Hi everyone, I came here today because I have an extremely frustrating problem that I can't find a solution for.

I recently ordered and received one PCI-e Multi I/O card: a Moschip MCS9901CV-AA(EoL);

it's a PCI-e (x1) card to add a Parallel port to my computer.

Problem is, when I add this component to my PC, the monitor will stop displaying anything. However, the video card, a NVIDIA GeForce 8600 GT, is still turning on.

When I take the component out, the monitor will display things normally.
Also I already installed the drivers for the PCI-e card, but it didn't do anything to help the problem.

I'm running Windows XP Professional Version 2002 SP2 32-bit

System specs:

CPU Intel® Pentium® D CPU 2.80GHz
Cpu Socket Socket 775 LGA
3GB of RAM

it's a Dell XPS 400 with no prior Parallel Ports.

Thanks to anyone reading.

I recently bought a barebone and a few components to build my new PC, however I cannot get any display output from the machine.

Here's how it is...

Processor fan spins, green led on, HDD's spin and CD Tray opens.

Ram, Processor and Barebone have all been replaced at least once.

Machine has no speaker, so I am unable to listen for beeps, although I do plan on buying one soon.

I believe the bios is upto date, which does support my processor. (rev 1.01g printed on mobo and 0404 on sticker)

I have tried onboard vga, dvi and hdmi as well as a PCI graphics card along with several wires and monitors.

CMOS has been cleared several times.

And I HAVE connected the 4pin power plug.

I have also tried the setup with minimal components (no HDD, CD), and no difference.

Processor: AMD Athlon II X4 640
Barebone: Asus V6-M4A3000E (380w psu)
Ram: 4GB DDR3 1333Mhz x 2

Note: For a while the machine turned on but the front light did not and the processor fan span a little slow, after lots of messing around both these issues now appear fine, still no display output though).

Any help would be greatly appreciated as I am totally stumped.

Hi, I have a thinkpad X230 laptop, ths screen was damaged so I decided to remove it, and then I stripped it down to the motherboard as I really only want it for it's computing power. The issue is, after updating the bios, there is no display output, I assume everything works fine as the fans spin up and there are no beeps. I have tried using both the vga output and the mini display port without any success. I had the same issue when the original screen was connected, the only way I got around it was by closing the lid, which the device no longer has, as it is literally just a motherboard.Any suggestions would be appreciated, thanks.

Hey. I just finished installing my Win7, and having a major issue.
I have a MSI Ex600 which has a Nvidia 8400M graphic card. The card only has a VGA output, and for some reason, I cant make my laptop to recognize my 22' Mag screen as a seperate monitor. When I click the identify button, it just shows '1' or '2' on both screens, and it drives me insane because its not supposed to be like this, it makes 2 major issues:

1. When I close the lid, the monitor shuts down aswel
2. The laptop is running on 1200x800, so when it pops up on a 22' screen, its just huge nd not comfortable to use.

It only recognizes it as a different screen when I do the "Extend" otion. but I dont need nor want that atm. I just want to be able to seperate my monitor from my laptop and have it run on a bigger resolution, like it should.

I heard theres something about the framerates, and i tried changing it to all possible options but still got nothing. every time i try and send it to the big screen it just says "Mode is not supported" and gives me a range of Hrtz that changes every time I make it on a nother resul.

Please help me. I'm going insane here because its not fun working like this and it annoys me having my laptop open all the time.

I have to mention that I did get it to work once, but I restarted my CPU and I couldnt get it right again since, I tried everything but nothing worked. just pointing this out so you know there must be a solution, because it worked once.

A:Laptop, VGA only output, and Multi Display problems.

Hello Gisenu, welcome to the Seven Forums.

If I understood your post correctly, your displays are working exactly as they should in Win7.

You find all display options from Screen Resolution tool by right clicking desktop and choosing it. When desktop (display) is extended, if you want to use just one display you have to first make it your main display and then disconnect the one you don't need:

When using duplicated desktop and you want to use only one display, you have to choose Show desktop only on X, where X is the number of display:

If desktop is duplicated, screen resolution is same on both displays. In that case the resolution can not be bigger than maximum resolution on the display which has smaller maximum resolution.

When using extended desktop or when using just one display, resolution can be different on all displays

Hope this is not too confusing...

Hi there,,
Yesterday I bought a new Asus P4R800-VM motherbaord. Thats the one with the ATI 9200 intergrated graphics. So I install and plug everything in as with the old motherboard but when I switched on the PC everything seemed to be fine. All the fans were running...my AGP ATI X800 card was running the DVD-rom and CdRW was working..the motherboard's light is on to indicate power...all but the display. My monitor has a screen which says that there is no signal from the PC! So I plugged the video cable into the onbaord VGA slot but still no image! I have 500w power supply...could it be that the problem is that there isn't enough power? Also I have one PC2100 memory stick and P4 2gig.

Anyhelp will be appreciate seeing that I can't even see the boot screens!

A:P4R800-VM mothernboard -- No display output to screen!!

If you have transferred the HDD from the other PC, and the new PC has different hardware then thats problem #1.

Unsure if it is your main problem, but its usually futile to do this as when the new motherboard tries to boot, it gets force-fed all the wrong drivers.

Windows does not like that and will usually halt the process to avaiod damage to the devices.

Is this the case with your setup? Needs a new install of Windows (boot from the CD)

I was having trouble installing the driver for a new graphics card, so I deactivated the On-board Intel video driver.
System rebooted fine immediately after doing this and had the basic safe mode graphics display, but still could not get the new driver to be recognized, so as a desperate act of stupidity I deleted the On-board driver.

Now there is no video output what so ever, nothing at all during boot even, so finding it hard to repair windows or reinstall onboard video driver. (I have the original motherboard disks).

I've tried safemode approach, and also the "wait till fully booted then using 'windows + U' to get the vocal screen reader but no approuches have worked. (I've of course tried booting with windows disc, motherboard disc and new video card driver disc. Also tried different monitors and all the output plugs at back. also tried taking graphics card out etc.)

Any advice would be much appreciated. Cheers, Adam.

A:No Display output after disabling video driver on motherboard.

Welcome to TSG.
If you didn't previously told the computer to have dual display, meaning allowing an external monitor, it will be hard to do anything and you might have to install everything from the original disks, unless you have some kind of a networking already set up on that computer and you could access your files from the network to save your files

I also have a digital audio out running to my receiver and a VGA hooked up to my LCD TV. Whenever I want to throw on a video for the kids, I have to go into sound properties, set digital out as my default audio, hit "OK" then go over to "Screen Resolution" after right-clicking on the desktop, setting the "Multiple Displays" to "Extend these Displays" hit OK then OK.

It may not sound like a ton of work each time, but I do it really often and I'd really like to automate it to one or two clicks. I was looking at ways to do it w/ VB Express, but couldn't figure out how to control video/audio settings. Any suggestions?


A:Would like to automate some processes - change audio output/display


what you need is to download and install autohotkey and use the scripts below

Windows 7 Tip: How to change the default audio device with a hotkey

you can click on the source of the article to get more information

this will deal with the audio part

then use this script that i wrote to deal with switching the video


place the scripts in your startup folder if you want them to launch at startup.

i have a similar setup so hopefully this will solve your problem.

Hi there! I was plugging back in a Dazzle DVC100, a video game capture device, when I got a blue screen. This has happened to me before on a previous computer, so I wasn't too surprised.

Upon reboot, my monitor couldn't pick up any signal from my video card's HDMI or DVI output. My OS boots fine, so I know it's not a hard drive problem. I was able to use my Mobo's VGA output and load BIOS and Windows. Therefore I'm led to believe it's some sort of problem with my Video Card. I receive error codes A2 and 9C upon booting through the CMOS debug. Any suggestions as to what I should do?

My build:
MSI Z97 Gaming 5 Motherboard
Intel i7-4790K
MSI Radeon R9 390X
Corsair Vengeance 16GB (2x8GB) RAM
Cooler Master Hyper 212EVO

Hi and welcome to TSG.

Your description would indicate a possible GPU problem.

Have you physically removed and reseated / checked all the connections for the GPU?

What is the exact make, model and wattage of your power supply?

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.

Hello, as i stated in subject i own lenovo v330 laptop. Last month i spilled beer over keyboard and everything worked fine for 2 weeks. After two months display stopped working, but when i connect laptop via HDMI to the TV i can see desptop just fine. I would also note that under very bright light i can see what is going on on laptop's display, but the screen is very indistinct. My question is,  is there any simple solution to my problem? Is there any specific place where i should take a look inside laptop to figure out if my laptop is still repairable? If not, would it be possible to change motherboard? Is that someting i could be able to achive with minimal skills when it comes to such repairs ?

Hi daproof,
Welcome to the Community Forums.
You may need to replace the LCD panel.
You can check on the hardware manual (here on page 63) if you have the tools and skills to change it. You can get the LCD OEM part number here to check online or on service parts center to purchase.
Here is the article guide that can also help.
How to Look Up and Purchase Accessories, Upgrades, and FRU/CRU Replacement Parts
At this point, it is likely a failed lcd backlight as image still is visible onscreen when illuminated but you can try to reseat cables first and check areas you can clean but setting expectation for LCD panel replacement.
I hope this helps answer your query.

Hi, I installed the most recent firmware update (fwdphb07) and run into problems with my T450s: My displays (two attached via DP, the main display with DP 1.2) stay blank until the windows login screen shows up (no windows is starting screen). The problem is that I have a SSD password so the password dialog is not shown on the external screen. I downgraded the firmware to fwdphb06 (installed fwdphb03 before, because fwdphb06 does not allow for a direct downgrade) and everything works fine again. @Lenovo: can you please fix this issue - if you need more information please contact [email protected] users with the same issue: try to downgrade the FW Have a nice dayMichael

I have been using a Display Port to HDMI Cable with my M92p for a long time now to connect to my 2 Philips Monitors. I now wanted to connect my M93p the same way and I'm now struggling to do so. I just cant get a signal out through Display Port no matter what I do neither in Bios nor on Windows. And on the PC side, my Monitors are not recognized at all. As my setup works with the M92p, the cable and Monitor are OK I guess. Why does M93p fail? Apart from VGA, the Display Ports are the only other Option. I read that M92p has DIsplay Port Version 1.1. and M93p Version 1.2: https://forums.lenovo.com/t5/ThinkCentre-A-E-M-S-Series/M93P-Displayport-1-1-or-1-2/td-p/2174499 But I also read that Cable wise this schouldn't make any difference. https://en.wikipedia.org/wiki/DisplayPort#Overview WHats the problem here? WHy is Display Port Output not working on M93p while it does work on M92p?

The title says it all. I'm very frustrated with this problem since I really need to connect my laptop to an external monitor for work. I've read and tried all relative topics in this and intel forums (e. g: https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Yoga-920-can-t-connect-to-any-external-mon...), have done all steps mentioned (including firmware, bios and windows update, windows reset, ...) but the problem still persists. Apparently, most users that had faced the same problem been able to get it worked after installing "Type C Firmware for Windows 10 (64-bit)" or the BIOS update provided by Lenovo. I installed them successfully but nothing changed. I am sure it is a software issue since there is no sign of any hardware one (all devices are fine as device manager shows and diagnostics app found no problem). It was just working fine until suddenly stopped working (probably after some recent windows update). I would greatly appreciate any help.

Okay, here's what I want to do. I want to send video output to a Plasma in my family room and also have output to the computer monitor in the adjacent office. I have the option of using either VGA or DVI to either monitor, so I can use a video card that has dual VGA/DVI outputs. Or, I can buy a separate PCI video card. Right now I have an ATI All-in-Wonder 7500.

Am I better off to get a new video card with dual monitor output or have two separate video cards. If the former, what video cards do you recommend? I know I've seen recommendations for the 9600 Pro, which seems to have dropped significantly in price? I'd like to stay with ATI as I've always used that.
