impossible to change Screen Resolution

[ghost]

Hey, i want to change the screen resolution in cubian x1 on cubietruck to 1280 x 600, because my beamer cuts the rest of the image from 1280x720. But every changes in uEnv.txt oder script.bin are without results. Any suggestions how to do that? i am searching for a solution since friday :(

These machines only support 1280x720, and 1920x1080 resolutions. This is hardware-limited, it has nothing to do with software, you won't be able to use a resolution like that.
