HELP! Using HDTV as monitor, screen is blinking black then normal again!
Hi

Im new here so sorry if this is the wrong place to post this.

Here is my problem:

I have just recently purchased a new Philips HDTV (32") and I have connected my pc to it via hdmi. I use a dvi-hdmi converter via the DVI port on my graphics card (NVIDIA XFX GeForce GTX 260).

The screen blinks and changes to black for a second usally displaying no signal or unsupported format in the top right hand side of the screen. Then it switches back to normal. The blinking happens randomly but never takes longer than a few minutes to happen.

I have all the latest Nvidia drivers installed.

One more thing I had a 32 inch tv before this one and it worked ok. It had issues with the text being blurry and it ended up blowing .

But any help would be really appreciated!

Thanks in advance!

Your computer screen display resolution has to be same with the HDTV. First of all check your HDTV highest display resolution from Internet (or NVidia Control Panel) and setup your video card display resolution same as HDTV highest display resolution. You can do that easily on NVidia Control Panel.

Change the PC resolution? If I hook my Sony VAIO FZ38M up via HDMI, I sometimes get flashing and no correct picture for a while, and often no mouse on either screen, change the resoultion to the highest possible on the PC.

It is on the highest, the problem is the screen flashes black and then normal again all the time.

I really don't know how to fix it.

Ive tried changing res and refresh rates nothing seems to help.

Oh and I can run it in safe mode without it blinking/flashing

Did you install N-Vidia Control Panel? If yes, you can easly setup at "SET UP MULTIPLE DISPLAY" section at left side of the screen. You gonna set your HDTV is primary and pc screen is secondary screen.

Yes, I have always had Nvidia control panel (my version is Ntune) and I have tried all possible resolutions and refresh rates. It is not anything to do with that I think.

I really need help with this

Thanks
