I've tried just about everything I can think of with the config.txt file, including changing the buffer, maxbuffer, hdmi timings, display hdmi rotate, etc, but I cannot produce any good results. I've changed many of them 1 at a time, and then some in conjunction, and the closest I can get is a square. Check out my images and the original config file below. Any bright ideas?
Before anyone asks, yes I've updated the OS and the screen rotates just fine when I attached it to a windows 10 machine and extend, lol.

Here's the config.txt on its own. Fine, right? (Let's just rotate that 90 degrees, right? )
