Hey guys,

I'm been trying to resolve an issue lately but have ran out of ideas.

About a week or so ago, i noticed all videos i played through my computer would show flickery lines at some points. After further testing, i noticed this occurred with all types of videos, including YouTube, DVD's and FlipHD videos saved on my hard drive.

I tested the same videos on my laptop and no flickering occurred so I know it's not the content itself.

Have installed the latest drivers for my video card but no change. 

Computer stats:

Windows 7 64bit
4gb DDR3 Ram
 i7 cpu @2.67ghz
 NVIDIA GeFource 9500 GT graphics card


Any help would be great! Cheers

Or got another video card to test it with ?
Do 3D apps (games) have the same problem ? (if not a gamer, download 3dmark and run that)

rscole86: Have you plugged your monitor into another desktop or your laptop to see if its faulty?


Have just done another test, should have thought about this before...

My LCD monitor is connected to the computer via the DVI input.

I recently ran a 10m cable to connect my TV in the lounge to the computer and that is connected using the VGA input.

I noticed that when the TV in the lounge is connected, the flickering occurs in videos on my LCD monitor in the office. If i unplug the other cable, the flickering stops.

Is this typical?

Doesn't occur in games, only videos.

What resolutions and frequency have you set your monitor at? Can your monitor be connected via vga? Or are both your ports DVI and you are using adapters?

I have one DVI port, one VGA port and one HDMI port.

Using DVI for monitor with flickering issues while other tv is connected to the VGA port.

I could borrow a VGA splitter from a friend and see if running both from the VGA port fixes it.

Resolution is 1360x768, 60hrtz (only option selectable)

Well if I plug both my monitor and tv into the one VGA plug with a VGA splitter, both screens are a lot less bright. It does stop the flickering though, but it's not as nice of a picture as i had before.

I also noticed it wasn't just video, i could see the same flickers when dragging folders around really quickly.
