Help needed here. I noticed that the picture on the monior under vista is blured like I`m using below native resolution 1920x1200. I opened display settings and it is saying that is 1920x1200. I`m pressing auto on the moniotor restart settings from the monitor menu. Nothing still blured picture. Than from the settings inside the monitor I noticed that is saying that is at 1600x1200 resolution and display settings from Vista say that is 1920x1200. And I think that both VIsta and monitor readings are wrong. Because the picture is blured like I`m using 1600x1200 but it is proportional like I`m using 1920x1200. And when I set proportion from moniotor menu to auto the picture shrinks in 4:3 ratio like I`m using 1600x1200 and in properties in Vista is 1920x1200. I changed to second DVI port on the VGA and Vista is not letting me to set res above 1600x1200. I reinstaled drivers. I have tried 3850 and it is working like it should. Put back 4850 in and problem is still here. WTF ?
