Hi, can you please add address and code for 3840x2880 (proper 4:3) resolution for this and future firmwares so the 4k ultra mode can be modified to this resolution?

so this:

set 4k ultra to 4000x2700

NTSC

writel 0xA064DACC 0x0A8C0FA0 writew 0xA064DAD0 0x0403

PAL

writel 0xA065444C 0x0A8C0FA0 writew 0xA0654450 0x0403

how to make to be this:

set 4k ultra to 3840x2880

NTSC

writel ? writew ?

PAL

writel ? writew ?

or can you explain how to do it myself?

Thank you.

0x0A8C0FA0 -> 0x0A8C and 0x0FA0. 0x0A8C = 2700 and 0x0FA0 = 4000

So if you want 3840x2880 2880 = 0x0B40 3840 = 0x0F00

So you would put: 0x0B400F00 instead of 0x0A8C0FA0 to get 3840x2880
