There is a reason why the GUI is rendered at 720p even when the display is 1080p.

And the reason is ..... ¿?

The only reason I can figure out is the lack of performance.

Almost ALL arm devices just don't have the GPU ponies to render GLES in 1080p at decent frame rates. Facts of life, the wild thing is the raspberry PI can do this Go figure.

I feared it. I guess you mean rendering the menus, etc. At least, they HW decode and render video in 1080p, don't they? How many "ponies" does it take? Dual core GPU? Quad core GPU?
