M270KCJ-K7E low brightness problem on monitors without USB

Hi, my monitor VG270U Pbmiipx has an M270KCJ-K7E panel wich is famous for very dim on some acer monitors. For a bunch of monitors Acer releases firmware updates for solve this issue, but obviously only for models with USB for user-friendly update.
Hovewer I have a skill to disassemble my monitor and flash directly it through external programmer. It would by very handy if Acer release firmwares for this kind of monitors too.

My particular has a main board 715G9400-M01-001-005K with firmware V0.03 from 2020-11-06.

Tried my luck with available firmware from XV272UV, but this wasn't work, seems it has a different controller.

Hi @GlooM,

Hi did you try to Adjust brightness level.

Yes, just for comparision I installed "Lux Light Meter" on my phone and tested two monitors on white color with 100% brightness.
My old VG270Ubmiipx can achieve 476 Lux, but new VG270UPbmiipx can only 246 Lux.
Yes, I know that is not a precise measure, but it is okay for compare two monitors. Both monitors advertised as 350nit in SDR mode, but in reality they has a huge differens

Similar problem with another monitor was described in this article https://www.rtings.com/monitor/reviews/acer/nitro-xv272u-kvbmiiprzx and it can be solved by new firmware.

Hi @GlooM,

What exactly you want to see? Two monitors side-by-side on a one photo? It is rather difficulty now, as the both secured on table mount stands on different tables.
