Video will not play on primary mon\itor

[wtmac]

I have 2 monitors on my system and as of this morning Video will only show if I select the 2nd monitor for video. If I try to have 2nd monitor do nothing the primary monitor will display just a grey box but will play the audio portion of the video. This is after moving touchjams to a new pc. It worked correctly for a few days and then not. I have installed and uninstalled both Klite and Touchjams.

AMD Ryzen 5 3600

Video drivers, probably some update on Windows 10 broke something.

Check installed updates and try and rollback your video driver.

Also, you may have to setup your monitors again in Windows and also your GPU software.

Check your Desktop is set to EXTENDED.
