vga picture has wavy lines

post #1 of 13
Thread Starter 
so i am trying to get a picture through the VGA port on my monitor(not the one in my sig rig) which has just 1 DVI and 1 VGA port. i have tryed cable after cable and figured it was just my adapter so i ordered a DVI to VGA cable(bypass the adapter) and the picture still has scan lines all over the place, icons have ghosting, etc! What is wrong?

in both monitors? Unlikely, but still possible. I ordered a triple shielded VGA cable to see if that fixes the problem. I switched a cable and plugged the adapter back in. it still has scan lines in games but no ghosting

That's common. Dude, VGA is oldschool tech, that should have been abolished years ago, but it's too entrenched into the pc industry to die so easily. The first step in the right direction is the number of new video cards that do not include a vga port (just a dvi-vga adapter).

The main reason I find for the wavy lines is that VGA uses an analog signal, which means it is subject to interference. Try rerouting the power cables away from the video cable. Also try turning off your speakers, re-positioning other devices that may be on or near your desk. You may also find that the wavy lines are reduced or eliminated if you run a lower resolution.

DVI, HDMI and DisplayPort are all digitial, they are naturally much more resilient to interference. You should be using one of these if at all possible.
