I have myself a Sony PVM-14N2E which ive tried my best to show a good picture

So gooooood
However i have a consitent issue when showing white on the screen, the more white, the worst the distortion

These are ment to be square



It really dosn't like that white bar there...
So as you can imagine, this causes problems with games that have to much white on the screen, sometimes flickering if its too much, i can indeed lower the brightness, however only all the way to the minimum making everything else look near black.

Setting are near unplayable levels just for the sake of no distortion by the white.
And sadly there arn't alot of settings i can see i can really mess with

We have brightness, focus and, rgb focus?, regardless these 3 should be fine. And even if i changed any of these, over time the screen corrects itself.

Pretty sure this is all it needs to be.

There is alittle switch that can set the horizontal offset on here but other than that i dunno what else is going on here.
Any advice on how to fix the over brightness and white distortion would be greatly appreciated. :3
