I just picked up a Viewsonic vx2268wm hoping to be able to play Counter-Strike 1.6 in 640x480 with 120hz refresh rate. Using the DVI-D Dual connector that came with the monitor, I'm currently able to set my desktop and CS both to 120hz without problems on my native resolution... but I need to be able to play on 640x480.
If my desktop is on 1680x1050 (my native res) @ 120hz, and I open CS with -freq 120 in launch options, it opens in the desired 640x480. However, while Counter-Strike is running, the screen gets a hue/fuzziness to it. Everything responds in time and looks normal as far as the resolution goes, but there is a constant hue/fuzziness to the pixels. It almost looks like an old television that is getting a barely shaky signal through an antennae (if I had to try and describe it). This same thing happens when I use nVidia control panel to make a custom resolution of 640x480 @ 120hz. If I open CS when my desktop is like this, it stays the same hue/fuzziness.
If anyone knows how I can use this monitor to play CS on 120hz in 640x480 please let me know, I'd really appreciate some help.
