I have the G74SX, with 192bits 560m, and 60hz lcd screen. (no 3d).
With the asus VGA drivers, I only had a subtle grid artefact on dark shades of grey, it is the only disappointing thing on this beast, as I'm a graphic designer.
But, with the last 290.36 Nvidia verde drivers, (and the last WHQL verde one too I think) the grid has been replaced with a scanline effect, in dark gradients, it's not like banding, I'm in 32bits, and gradient are very smooth, but the scalines appears, ike a pattern or something, I took a picture of my screen with my phone, because obviously, you will not be able to see it with a screenshot :
Any idea about what is causing this ?
I apologize for any grammar mistakes, as I'm french.
