Display Flickering, Need Spliting HDMI Signal?
Jul 15, 2012
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

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

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.

Sony notebook with HD AMD6630 M. HDMI port not giving signal to TV. When I rollback the Intel Gaphics driver the HDMI signal comes alive but then goes dead after reboot. I have been trying to solve this for 2 weeks without success.

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!

ive got a problem with my new viewsonic vx2753mh-led monitor. its got 2x hdmi inputs and one vga.the vga works straight off the bat, but whenever I try and plug the hdmi in it just says no input signal detected and goes black I noticed in device manager that this was installed as 'generic non-pnp monitor' so after jumping through some hoops i managed to install the driver as 'viewsonic vx2753 SERIES' anyway this doesnt seem to have made a difference. still no input through the hdmi.I have tested to cord on my samsung tv and it worked fine so it can't be a problem with the cord or the graphics card....just some general info that might be of use:
windows 7 x64
dual monitor setup
the graphics is integrated on the intel i5 chip my display adapters in device manager says Intel(R) HD Graphics Family.it has a dvi out, hdmi out, and vga out.

I've got some minor problems but still I find them quite annoying.
First: When I'm running Win 7 my display is flickering. It just looks like bad reception on a TV station. When it gets too bad the display turns blak and after a second everything is fine and it starts all over again.
Second: After a while Windows states that there is a problem with the Nvidia windows kernel mode driver, version 186.81 and that it has been restored. (This info is given after the screen turns black).
I think that there is a connection between those two problems but I don't know how to solve it.
I've got a nVidia Geforce 9650m GT grafics card and after I installed win 7 downloaded and installed the driver.
It is even worse when aero is running.
In Vista everything was fine.

I have been having troubles with my display port monitor, and I just realized that the monitor is picking up 1923x1080 60hz (thats what the HP settings say on the monitor) but according to Windows its sending out 1920x1080. ATI Radeon 5770, I don't have CCC installed because of previous issues, any ideas why I'm getting such an odd resolution?

I have been facing a wierd problem recently. My desktop monitor turns off itself after a few minutes but the CPU works, I can hear the fan running and see the lights blinking. One thing I noticed is that when the monitor turns off, the Orange light on the CPU stays on which normally just blinks. My PC works normally on safe mode, but the worst part about safe mode is that I cannot work on my software CorelDRAW. Can this be the SMPS problem? because recently my mouse and keyboard inputs were not working because of which I got a USB keyboard and mouse. I have recently installed Windows 7 64bit, but I think that should not cause the problem as I have worked with 64bit Windows before on the same machine.
PC configuration -
Intel Core 2 Duo 4500 @ 2.20Ghz Processor
ASUS P5QPL-AM Motherboard
3GB RAM
No Graphic Card (Maybe inbuilt, not sure)
1TB Hardisk

Just recently was doing some additional overclocking on my PC and had this happening just now. Whenever I resume my session out of sleep mode by hitting either a key on my keyboard or mouse, my PC fires up, but the display doesn't come back, almost as if I had pulled out the cable from the monitor. The PC is running normally as this is going on, and the only way for me to get my display back is to do a hard reset.

I accidentally deleted all the display drivers off of the computer, the computer restarted and now the computer has just seemed to screw up completely. The computer turns on however I get no signal from the monitor, it's on but nothing on the screen so i cant get into BIOS or anything.
I've tried:
- Using different cables
- Taking out and putting the CMOS battery in
- Using different Monitors

I have my Iiyama prolite connected via dvi and another TV via HDMI.As soon as the HDMI is plugged in I lose the DVI display and it transfers to the HDMI. The DVI is no longer detected.Does this mean if I want a second monitor I will have to set it up through VGA?

I use my computer mainly for living room entertainment and I use my HDTV (LG LED 1080p) as my main computer screen. Everything used to work fine but I've recently started having problems with the sound. When I turn the computer on, the sound works perfectly. However, if I close the TV or change the input from my computer to anything else, and then go back to the computer, the sound is gone.I looked through the sound options in the Control panel and noticed that the sound problem comes from my TV speakers (identified as AMD HDMI output) being unplugged. This is obviously impossible because the speakers are in the TV so this must be a Windows problem. This output works perfectly when the sound is on.My TV is connected to my computer through a single HDMI cable for sound and image (ATI Radeon 5700 graphics card and ASUS M4A79XTD EVO motherboard on-board soundcard, both with latest drivers). I use Windows 7 premium home edition 64-bit and I have 4 GB of RAM. i found that either logging off from Windows or restarting the computer will bring the sound back on. Unfortunately, as soon as I turn off the TV or change the input, the sound goes off again.

When playing back two channel pcm music on my diy home theater computer, the output begins to progressively contain random static as additional tracks are played. The operating system is windows 7 64 bit. There are no issues with 5.1 audio as it is always clean.My motherboard is an Asrock H67M and my processor is an i3-2100. The computer is connected to a Yamaha receiver via an HDMI cable.Video from the i3-2100 is outstanding on my 52" Sony TV. I am using the on board Intel display audio device as this appears to be the only way to transmit digital audio output to the receiver via HDMI. The only way to get clean sound when the static becomes unbearable is to turn the computer off and reboot. I'm not sure it matters, but the computer does contain a TV card.

I connected my HP Pavilion dv4-2165dx to my TV via the HDMI slot, and worked perfectly. I disconnected the cable from the notebook when I was done and still got the main LCD display to work. When I restarted the system, the LCD display was gone, just a blank screen with a backlight. The system is booting correctly, I can hear the windows7 startup sounds and even type my password in and access my account. So far I know that:
1. The screen hardware is not damaged, because after some reboots and taking the battery off for an hour I could get the input back with no problem (with windows complaining about being unable to boot and suggesting me to run Startup repair), but got a black screen again after rebooting again.
2. I can connect the HDMI again and get the output on the TV screen, but no main display is detected. If I toggle between displays with fn+f4, only the external HDMI-TV display works.
3. I get no startup screen either. That is, not even the first screen from where I can access the BIOS. But if I connect the HDMI-TV from the beginning I get all that info on the TV.
4. I reinstalled the Graphics driver from HP with no change.
My guess is that somewhat I messed up the default configuration and that the system is only recognizing the external displays as default displays. I haven't been able to modify this from the Control Panel - Display Settings menu, and I don't know where in the registry this default startup options could be.

I have an HP Pavilion Elite HPE machine, Windows 7, Radeon HD 5700 Series graphics card, connected to an Acer monitor and HDTV. Here's details on my setup:
My Equipment | Building a Home Theater With Your Office PC
My problem is that even though my HDMI cable's plugged into my Radeon graphics card, sometimes the PC only recognizes the Acer monitor and not the receiver (that's connected to the HDMI cable and my HDTV). So I end up having to plug and unplug the HDMI cable several times (sometimes 10+) before it recognizes the HDTV/receiver connection. Is there any setting that would favor the card/PC recognizing the HDMI cable more frequently? I've heard it's a handshake issue, and that maybe using a different type of cable would work. But wondering if there's a setting I could use before switching out cables.
