27" Monitor Flickering only at 1920x1080 res. Can't RMA

post #1 of 6
Thread Starter 
I have the 27" Asus LCD with LED Backlight monitor and I get constant flickering, weird color inverting, screen going black for 1-2 seconds when the resolution is at 1920x1080. I RMA'd the monitor and they sent it back saying it's not faulty and my GFX card must not support that resolution. I have an HD5870 and a EVGA E760 CLASSIFIED motherboard I can't imagine them not supporting 1980x1050...

Any recommendations on what I can do? I can't leave the res @ 1680x1050 as it looks terrible.

You try replacing the HDMI cable or DVI cable? Most monitors don't have native support for 1980x1050. They do however have native support for 1920x1080 which is full HD.

I believe you certainly mean 1920x1080 (not 1050).

Have you tried running driver sweeper and then replacing drivers with the latest? who knows.

Or perhaps seeing if asus has drivers to download for that very monitor. It is weird that it only happens at the max resolution setting.

You have some troubleshooting to do. Test all related cables with different ones (power, dvi/hdmi, etc). Try a different computer or card if you have one. Then post back with results and what you changed.

Sorry I meant 1920x1080. I updated my GFX Drivers, and couldn't find drivers for the monitor. I'm using the DVI cable it came with, I'll try buying another one and seeing how it works. At first I was using HDMI and it didn't flicker, but the picture quality was awful, and I was told by some people on this forum to switch to DVI.

Then it's likely the DVI cable.

Whoever told you to switch to DVI because it was better than HDMI needs their head examined.

HDMI and DVI are both the same digital signals. Major difference being that the HDMI cable can carry audio as well as video in just the 1 cable. If the picture quality looks different then with DVI, it's likely because your monitor adjusts color when using the HDMI cable. You could just change the color settings on the monitor if you don't like that. Otherwise, it's the same digital signal.

That is why I believe it's the DVI cable, and not the monitor. You get a proper signal with no flickering while using the other cable (HDMI cable as opposed to the DVI cable).

Swap cable. Rules out fault on the monitor. Simple.
