I have a OP6 and I found an XP-Pen drawing tablet that I can use with Android via an OTG adapter.

It works, but the problem is, the active area is a 16:9 ratio, while the OP6 is 19:9. So anything I draw on the tablet ends up a little squished or stretched.

I was wondering if there's an Android utility that can alter how much of the tablet can be used at one time, and fit it into a 19:9 ratio probably, with a margin of the active area disabled.

Or if there's something that will change the aspect ratio to 16:9 via software.
