Hi everyone! I posted it everywhere and got no solution.TechSpot is my last hope. I have 50 cm samsung LCD and nvidia 9500GT installed.Screen resolution is 1600*900.My problem is that whenever i connect my monitor to Graphic card's vga port, then Gray hum bars are seen on the whole screen.These are not visible on bright colors, but i can see these on light dark colors and the whole screen seems to be shaking. When I connect my monitor to my motherboard's vga port, then everything is fine.There is no problem there.This only happens when I connect monitor to graphic card.If anyone can help me with this issue, it will be a great help for me. Thanks in advance!
