The resolution is fine on a 49″ TV viewed from 3′ (my zoom room setup), but it’s also fine with a 125% zoom. Then I read the text in a NoMachine session, which I do a lot.
I tried adjusting the native display zoom through a NoMachine session and NoMachine got confused; the display was messed up and slow to refresh. Even quitting the session and trying again didn’t help. But changing the zoom natively and then opening NoMachine worked fine.
