Can't get 4k (not even at 30Hz)

[heinzdembowski]

After finally figuring out that the values are little endian, I was able to set a maximum of <0000e001> for framebuffer-stolenmem. This allowed me to use a resolution of 3440x1935@40Hz through USB-C + DisplayPort which is a good compromise but no solution. I would still be happy for any help.

Should I ask in the WhateverGreen thread?

@heinzdembowski,

If using WhatEverGreen you need to add the -cdfon boot argument to enable 4K
See the last part of the whatEverGreen section of this guide :-

I have this argument, but thanks for the tip.

I have the same problem - have you been able to solve it eventually? Thanks!

No.
