Can't play PTR. Only 1/4 of screen is visible. D2r No problem

The game only shows 1/4 of my display (up/left quarter of my screen) the rest stays black, yesterday there where no problems, no setting changed before log of.
D2 r (no PTR) runs fine.
I did a scan and repair and there where no issues with the files.
Any help or advice would be great. ty

The issue got resolved. Don’t now what changed, but i can use fullscreen again.
