ASUS VW222U colour banding problem

TarJak · 12-06-07, 12:56 AM

I bought one of these 22" LCD monitors the other day and after a bit of researching and tweaking, managed to get it set up reasonably, running in native 1680x1050 resolution @ 32 bits per pixel, until I ran SHIII with and saw the night scenes and this is where the problem lies.

The colour gradients are all banded very noticably. What I'm seeing looks more like the image on the left What I'm used to with my CRT is what it looks like on the right of this image:

I've got a Nvidia GF 7900GS which has two CVI ports and I'm using the DVI cable that came with the monitor on one and am still running the old CRT via a VGA adapter out of the other one.

My nvidia 3D settings are maxed out 16x AF and 4xAA, Supersampling, Triple buffering and Trilinear filtering all on. I'm running the latest nvidia driver set. These where the settings that I ran using just the CRT.

I tried dialing the 3D settings back and no dice still the same banding. I've also seen it happening in dark scenes on DVD's/movies so it's not just the 3D rendering thats a problem.

I've hooked up my old CRT and the same game and movies work fine with the same settings but using a VGA cable, so I'm starting to think it might be the screen.

Just hoping someone can assist as I assume it is either a settings thing or the monitor is simply crap and I need to go back to just using my trusty old 19" CRT.

Does anyone know what settings can be used to reduce or remove the banding?
