@Lokie A big favour to ask

I need to try and change this

vmode = <3>; /**0:VMODE_720P 1:VMODE_LCD 2:VMODE_LVDS_1080P 3:VMODE_1080P*/

to this

vmode = <1>; /**0:VMODE_720P 1:VMODE_LCD 2:VMODE_LVDS_1080P 3:VMODE_1080P*/

Locking my device at 720P. Where/What can I edit to do this ??

The reason being that I am using my vega in conjunction with my pioneer app radio and despite setting it at 720p (the only resolution the radio accepts) something in the firmware is indicating a default of 1080p and it is messing with my touchscreen calibration.

Any help much appreciated

You got the kernel source and can you compile it?
You need to change that option in your device tree that gets paired with the kernel image.
I'm quite new to this - just compiled my first kernel and need to test it now. Once i'm comfortable that I got it all right i'll help you with pleasure!
