Binary version of EDID
Many tools exist which can decode EDID.
On Ubuntu you can use
edid-decode
.

Human Readable version of EDID
WIP
At the we use a samsung display with same resolution and similar timings which works.
But to optimize the devicetree someone has to decode EDID to panel-timings
Controlling the following GPIOs from UEFI Shell gave the result below. The GPIOs were extracted from ACPI
GPIO | Backlight | Logo | Note | Function |
B2 | Y | N | Image fades out | LVDS power down |
DD0 | N | Y | Logo can bee seen with external light source | backlight power |
DD2 | N | N | Display is dead | panel power |
H0 | N | Y | PWM brightness control | PWM brightness |

Pin | |
2/3 Panel VDD | GPIO DD2 |
25 BL_PWM | GPIO H0 |
26 Backlight enable | GPIO DD0 |
28/29/30 LED Anode | Always connected to 12V |
