Problem with Photoshop Elements 2019

[tosstaler]

On Mac Studio, I can no longer edit the documents I created with Photoshop Elements 2029. The monitor no longer displays the documents correctly. Does the 2019 version no longer work on Mac Studio?

I will move this post to Photoshop Elements forum.

Two things come to mind, and one of them is prbably the problem.

1. Outdated video drivers.  (this is probably the issue)

2. Loose / bad cable to monitor.  This is rarelyy the issue, but even a kink in the cable can cause your problem.
