I was just thinking in terms of the most features for the most people, at least on the first release
Chris, you are aware that I'm talking about Rig Manager in the first place? We're way beyond first release, many years actually. And yes, I have complained before about the lack of scaling ... without success.
G, are you running yours at full 3840 x 2160 (-ish) resolution, or do you run at 1920x1080?
Given that G String is on Windows (which is the topic in this thread), he'd have to be pretty hardcore to accept the terribly blurry and awkward Windows system scaling. This would be very hard on his eyes and I would expect G "Eagle" String to turn into G "Mole" String in no time.
I would think if it was 1920 x 1080 that it would be normal size text but very clean due to the high dpi. However, it's running 3840 then couldn't you just change the res to 1920?
On Mac, system scaling is much better but it still doesn't make sense to pay for a 5K display just to restrict yourself to 1920x1080. There's apps that can make very good use of the higher resolutions. Rig Manager certainly isn't one of them though.
