After starting ZDMC 20.2, the resolution of the GUI changes to 480p.

Hello,
my Z9X Pro 1.0.80 is set according to Zidoo's recommendation. The display in Android is set to 4K60Hz. When I start ZDMC, I can already see from the splash that the resolution has changed. When I press the info button, it also shows me that I am in 480P. When I quit ZDMC, the GUI is changed from Android to 480P even though the Fixed switch is selected for the resolution. This has no effect when playing movies. This has been the case since yesterday. Before that it worked without any problems. Are you aware of this phenomenon?

 

I reset the settings in ZDMC and everything is fine. Topic is done.
