HDMI Works Before Windows 7 Log On Screen / But "No Signal" Once Hits Log On Screen
Jun 26, 2011
I am having an issue of HDMI working during PC boot, but TV loses signal just before Windows 7 log in screen comes up (TV shows "No Signal" at this point). If I use VGA to connect PC to TV, everything works fine. [code] One thing I noticed is that Windows 7 device manager sees my TV as a "Generic PNP Monitor". I have no idea if this is connected to my issue or not. The Intel website says my drivers are up to date when I run their update utility. The Intel Graphics utility on my PC sees my TV as a monitor, not as a TV, but it does list the correct model # (M260MV).I've tried connecting both the TV with HDMI and a PC Monitor with the VGA cable and the computer would only detect the PC monitor with the VGA cable.I have read on an Intel site that others with the Core i3 CPU had similar problems so this may be a CPU/CPU driver issue, but as I said, the Intel Update Utility says my drivers are up to date.

This is on a loptop Meldon E6882, running windows 7, to a LED TV HD. From a cold boot both the laptop monitor and HDMI screen show the windows starting screen .. But the HDMI screen goes blank when the login screen appears. I have tried different screen resolutions. No Luck. I have tried from the 'screen resolution' page to get automatically detect the HDMI - No luck I have tried from the 'screen resolution' page to manually select HDMI. Only offers VGA or component, no HDMI.
I think this maybe a disabled driver as I did a manual disabling of these some time ago in order to try and reduce the boot time. I cannot recall the names of the drivers I have put into manual start (some time ago), nor have I found any info on what drivers are needed for the HDMI. The screen driver is an Intel(R) HD Graphics 3000. I'd like to look at some video on the larger screen...

started recently, when I boot my PC, the screen shows message: no signal and screen stays dark.However, in the background W-7 is loading, but in order to get the video functioning, I must restart the PC, turn off the screen, wait till W-7 loads somewhat and (like after 10 sec.) turn the screen on and everything is OK.Monitor is NEW Video card too, I tried with a second one, same problem...My question is, is this W-7, main board, or something else related?

i have an HP Pavillion dv7 with windows7. It is less then 3 months old. Problem- Yesterday the screen went black while i was watching a video, but the sound kept going. so i restarted the computer, and the screen works until you get to the login screen it goes black again. SO i called customer service at hp, and we worked on it for an hour.THe one thing that seems to work is when i go to the device manager, uninstall the display adapters, and restsart in normal mode, then i go and reinstall the ATI device thing in the recovery manager, but everytime after i reinstall the ATI display device thing, it ends up going black a little while later again. lol

My problem is that if I connect the computer via DVI to a display it functions normally, but when I hook it up via HDMI to my Flat screen, it doesn't show the splash screen that gives you the option to enter bios. The screen just stays black until the windows welcome screen(win 7 64bit) comes up, then it acts totaly normal from that point. When I try to press the del key during the boot, I believe it is entering the bios, but the screen remains black so I can't see anything. I am guessing that the MB is not sending the signal to the Flat Screen until it loads windows, but can't find out anywhere that confirms that or what to do in order to resolve it.

I recently built a computer for my first time. It was running fine whilst playing Arma 2, dayZ and dawn of war 2. I then installed Star Wars The Old Republic and everything went on fine until I went to play the game. The screen went black and the no signal message came up on my tv.
I could not do anything so I just turned my computer off and then back on again. When I then went to boot again in Normal mode, it just shows the windows logo and then does the same thing.
I have tried booting it in safe mode, and this works fine. I don't think it is anything to do with my monitor as it works in safe mode and also it's my tv which works with DVDs and anything on TV.
Could it possibly be something to do with the drivers? Although I have been playing other games fine until now. Or could it possibly be something such as a corrupt file or the game installed something else which won't work?
Someone also suggested that it might be something to do with the power going into the computer? They said it could be putting too mcuh power into it and it would cut out.

I have a white box tower with a ASUS P5KPL-CM Motherboard I turn it on and I get a black screen, no signal to the monitor,so I plugged in my old Sony tower and the monitor works. So it's not the monitor or the cable( switched them a few times by now) I believe it is the new tower. I think it might be the VGA card but know little about these things. Manual says it is a Intel Graphics Media Accelerator (Intel GMA 3100).Or could it be something else? By the way I have Windows XP if that makes a difference.

I turn on the computer, goes past the bios screen as normal, does the windows loading screen as normal, then the screen goes black and the "No Signal" message is displayed.
Now, here is why it is different. I type in my password and press enter, without being able to see and wait for the logon sound to play, then if I unplug monitors cable, I hear the noise of windows telling me a device has been disconnected, I plug it back in again the device connection noise then plays and low and behold, there is the desktop.
I have been running Windows 7 build 7100 for roughly about three weeks until this started happening about one week ago.
MONITOR: ViewSonic VX1932wm
GPU: Sapphire HD4850 512mb
Also, I have noticed too after logging, randomly Aero will disable itself, I have to open the 'Personalize' option and run the troubleshoot to get it to fix itself again.
I assume this is the correct section, as I am experiencing visual issues. Apologies if this is not the correct section.

When I connect my PC to my TV Via HDMI Cable, my TV does not receive a signal. When I check in Control panel>Display>Resolution, My TV hasn't even been detected. My TV is an LG 50", Card is a GTX580, and my OS is Windows 7.
Also, when I connect my laptop to my TV via HDMI (Also on Windows 7), It is instantly recognised and automatically displays, so it has to be an issue with the PC itself.

So my issue is with all my full screen games, after a few minutes to a few hours the screen go's black and an error pops up on screen.
Signal out of range set to "1680 X 1050 @ 60hz"
Normally I would just put it to those settings, but the issue is these are basically my setting in the nevidia control panel my settings are exactly that. The only thing I could see is the advanced display settings are 59hz. But you can't set it to 60 because windows 7 rounds down instead of up now.

I have a Toshiba Satellite C655D laptop running Windows 7 Home Premium. Computer was working like a dream and has been for about a year now, when yesterday I booted up after running Windows update, like always, logged on like normal, only to see a blank screen with only my mouse cursor. Neither Ctrl+Alt+Del nor Ctrl+Shft+Esc work to bring up the Task Manager. I am able to boot into Safe Mode just fine, but of course unable to uninstall the Windows updates to the .NET framework.I have tried System Restore several times now, both from the Safe Mode and from the start-up recovery options accessed via F8 upon system startup. From the same menu, I have attempted Startup Repair but alas, Windows does not detect any problems (go figure, right? ).I have ran the Windows Memory Diagnostics Tool to check if my hardware was going bad, and upon completion, it rebooted, once again, to a blank screen after being prompted to log in. Mouse works, nothing else does. Upon pressing Ctrl+Alt+Del I am greeted with the following message after waiting roughly 5 minutes:"The logon process was unable to display security and logon options when CTRL+ALT+DELETE was pressed. If the operating system does not respond, press ESC or restart the computer by using the power switch."^Pressing ESC makes the message disappear along with my mouse, so that I am staring at a completely blank screen.I am on my friend's MacBook Pro right now, I'm really hoping someone can help, but I must admit I am reluctant to think so because someone once came to this board with the seemingly exact same problem and no one here was able to help him.Just to reiterate, I can boot up in Safe Mode, with or without Networking as well as accessing the Command Prompt. That's about all I can do.Edit: Now when I do a System Restore, I get this error message when it restarts (everything else is blank unless I restart in Safe Mode): However, when I try to navigate to this location either via Windows Explorer in Safe Mode or via the Command Prompt, one can clearly see that the location doesn't exist. I am confused.

Whenever I boot Windows 7, after it starts, instead of showing the login screen, it show a black screen with a movable cursor. Now, I can go into safe mode, and it works, but, hell, I can even put my password on that black screen, press enter and it will go into Windows and work just fine. But the thing is, it's supposed to show the login screen, not just a black one, so I'm a bit worried of what might be causing the problem, and whether or not it could expand into something worse.

I have done some searching but to no avail. I have tried everything I can find/think of with absolutely no luck.
I have a brand new Samsung LN46B750 which I have connected to my desktop for use as an HTPC. VGA works fine, but I would much prefer to use a digital connection. SO, I have an HDMI <> DVI adapter and a monoprice HDMI cable connecting my GeForce 6800 to the HDMI/DVI port on the HDTV.
I have tried 182.5 and the latest Nvidia drivers as well as the generic Windows 7 drivers. It's all the same.
Everything works fine in the OS so long as I make it past the Windows splash screen. And unfortunately, that never happens. I believe that the problem lies in the auto adjustment of the screen when 7 starts loading. (If I boot without the TV connected, and then connect after the splash screen has loaded, everything is perfect.)
Is there any way to disable the auto detection/adjustment of the TV and just have the OS always boot into 1920x1080 @ 60 Hz. I am really tired of the blank or black screen every time I reboot. This is a terrible bug with Windows 7 or EDID and it needs to be fixed now Microsoft!

I am pretty decent with computers but not an expert. I am having a little trouble with my home theater PC display flickering. My video card is a Radeon HD 6900 and the drivers are up to date. I have the HDMI out of my PC going to an Onkyo 7.1ch HT-R590 receiver and it's output going to my LG 42" TV. My OS is Windows 7 Ultimate X64.The system used to work perfectly fine but over time the display started to flicker at random times. I tried to hook my PC directly to my TV and it works perfectly fine, so I am 100% certain the problem is in the receiver. I did a bit of research and it appears to be a problem with my receiver over heating.
Now, if I run my HDMI to my TV, I cannot use 7.1ch surround sound. (Even after playing with Audio Return Channel) If I run optical to the receiver, my video card only puts out 5.1ch surround sound for some weird reason. So I did the next obvious choice, I ran a DVI to HDMI to my TV for video and HDMI to my receiver for audio. I thought it would trick it into thinking there was two displays but this does not work, I do not get audio. was wondering if you guys knew of any utilities that would allow me to output audio on one HDMI stream and video on my DVI port. I did a lot of looking around and it looks like DMCA calls for HDMI to be encrypted and you can't separate the stream. Or would I just be better off getting a separate audio card to connect to my a/v receiver

my computer likes to underscan when I connect to my 720p plasma tv over HDMI. it doesn't do this over VGA though. The problem is, In order to play Blu-Ray disks my software FORCES me to connect over HDMI, and my TV doesn't support DVI.I managed to get it close, but the pixel mapping is off. I can't get it any closer, as the adjustments only go by 5% increments.

I recently made a thread on this forum talking about how my new PC setup has suddenly started creating lines on my screen
Link: Wavy lines across screen, (usually grey-ish colours) on new setup.
After trying a full list of things; 2 different monitors 2 different VGA cables 3 different mice 3 different keyboards change power supply change graphics card used onboard graphics switched ram sticks and removed one at a time reformatted a dozen of times unplugged all sound from computer checked motherboard for any visual problems and couldn't see any updated all drivers I could possibly think of Ran Memtest for 7 passes with no errors I've finally found out the problem and that was when I connected my graphics card using HDMI to a HDMI compatable monitor it worked fine and I had no more lines!
So it seems that using HDMI is working fine but soon as I use a VGA cable its not working and the lines are back. It only confused me more when I connected a VGA cable from another computer to the monitor it all worked fine.
As far as I can tell it's something to do with my computers VGA/HDMI settings, I've tried onboard VGA and that still didn't work so it doesn't seem to be a graphics card problem just something is stopping VGA working properly but HDMI is working.
I'm gonna have to go buy an expensive new monitor with HDMI compatability.

Lately my girlfriend has been experiencing some flickering when connecting her laptop to my TV using a VGA cable or using HDMI. I know it's not the TV or the cables, since using my laptop (and others) worked fine.I updated her display drivers. She doesn't have a dedicated graphics card -- just one of those integrated ones -- but has never had a problem before. I'm not really sure what more to do for troubleshooting
