2560 x 1600. Is there hope?
 

This is the default res on my monitor. I didn't see any that match it.

I did download the "Uth" interface. I installed it, tweaked it just like the directions said, and oh boy, was my interface BORKED. I went back to the default, and still had to mess with settings for half an hour to get it back the way it was.

Two questions.

A - Was I doing it wrong? Does Uth support 2560 x 1600?
2 - Is there an interface for 2560 x 1600 default res?

1) Don't know for Uth but with some experience you can make most UI fit your res.

2) You can check my UI (Yessh), while you res isn't embedded I provide an XLS file that automatically generates the right code for any resolution. You can also check the file, it will help you understand how the UIs works.

1680 x 1050 is the native setup and the max I can test. I'm sorry to hear it didn't work out for your resolution. If you want to try it again I can see if I can rework the code for 2560 x 1600, but without being able to test it I would only be able to adjust it from your feedback.

Can you tell me what it was doing so I can have an idea of what goes wrong with it in higher resolutions?

DaimonUI supports 2560 resolution with a patch
