Today I've purchased a brandnew TFT screen to attach to my laptop.
I've noticed that I get "waves" which run horizontally over my screen, it's very visible with dark backgrounds but it also shows up on light backgrounds.
The screen is an Acer AL2206W (similar to AL2216W but no DVI connection), connected via a VGA cable. It's set on 1680x1050 resolution since that's what's recommended on the box and manual. The refresh rate is default, 60Hz.
I know the issue is with the screen since other flatscreens show no waves. I have no other screens, speakers, computers, power sockets or anything else close to it which could interfere with the screen. I've doublechecked the connections to make sure nothing is loose and there are no bent pins.
I've searched all over the internet for a clear answer to my problem, but these answers don't apply to me.
I honestly don't want to contact Acer tech support about this, I've dealt with them many times in the past and they never managed to give a clear answer to my issues.
Thanks for your help.
