Dedicated MK4 cab, the screen has a wavy background, the gameplay is fine, it almost looks like it's some type of interference or something. Does the same thing on all PCB's.

If you view the video and pause it at :27, you can see what I mean.. it's tough to catch but it's there...

Any advice on what to look for or what I can do to fix this would be greatly appreciated!

I've never had this problem myself, but to my understanding it can be caused by an earth ground or just a bad ground. if you have a green earth ground wire going to your monitor chassis, try disconnecting it. if there is none present, then perhaps that's what you need. :)

I'm sure you know what an earth ground simple looks like, it's like an arrow facing down with 3 lines... helps if you have a screw terminal power supply, cause you can just tap into that terminal and ground your monitor frame with it.

I guess it also couldn't hurt to make sure your monitor chassis is properly screwed in...?

what kind of monitor is it btw, do you know?
