I'm currently using my Vizio 32''(VX32L) as my computer monitor. I'm connected using a Geforce 7800GTX(DVI), the cable is VGA with a DVI-VGA adapter that came with my dell computer. The picture is fine except that there's 8-10 vertical 1/2'' lines running down my screen that make the picture where they are hazy, kind of like a like a focus picture. I only really notice it when reading text, it makes me squint. I noticed that these lines move left and right when adjusting the "Fine Tune" under the TV menu. My Question: Is this the cable/adaptars fault? If so, what brand do you suggest I replace it with? Also, I bought a HDMI DVI cable (24AWG) w/net jacket-15ft (Gold Plated) from Monoprice.com, thinking this would be a better signal, but I get an out of focus picture. I tried every option/resolution option w/ my Nvidia settings but to no avail. Does anyone have a solution to this problem? Thanks in advance!
