Is there any way to remove the red green and blue lines on top

Stupid iPhone. It rotated the picture as you can see. The lines I was talking about are on the left.

That may just be some extra graphical junk on the outside of the borders that's being displayed by the game console.

Are you playing a genesis game? the genesis is known for this.
Try a different system and see if it's still there.

Service menu = Degauss + enter
VBlank increase until lines are gone. I think Enter to save setting or Reset to go back. Keep note of what settings you have.

You're right on the service menu code.

On my 20L5 the controls are "H RASTER SIZE, H CENTER, V RASTER SIZE, and V CENTER" or something like that.

those three lines are common to all PVM and BVMs, as well as other brands of professional monitors.

It's full of obnoxious trip cunts though.

There are two, and the occasional harmless namefag or two.

It's the quickest and best way to get an actual decent answer at least.

Definitely a massive weenie, but it doesn't completely nullify the thread as a decent place to ask questions and find information in.
