What about the new P11 Pro (2022) with mediatake 1300T processor, what type of panel does this tablet have? Same as 2021 model or P12?It's so easy too jump to conclusions, and not do your own due diligence..
no doubt Lenovo FW leaves a lot to be desired, but the hardware is top nudge not least with the price in mind - and so is this 1600p RGB OLED panel Lenovo is using - as you can also see on Notebookcheck, where this panel tops the charts amongst all OLED tablets and also better than E4 and E5 AMOLED.. the only other model that can match its color check scores - is Ipad Pro 12.9" 2021 with its MiniLED, as I showed above with the pasted values.
This "LCD glow" you keep referring to that you encounter/encountered..- can often be down to other things, that have nothing to do with this product, but third-party aspects you are pushing on the item..
like numerous custom ROMs, third-party apps.. or simply the HDR container-.. where static HDR or dynamic HDR data does not play along with the app you are using and the black floor ain't referenced.
Also why its usually preferred to cut away as many chains in the link as possible, if you wanna decipher the reason for a possible issue your experiencing- and get it as native as possible to sense which factors are causing problems and if its fundamental?
This is what I have tried to show you in the pursue to help you, get to the root of your problems, not least with direct greyscale grading directly to a display app with finer and finer lines to black' as if there is a problem with the grading it will show itself, but it was ideal., and where you stated that you would make a video showing it, but you never did, and fair enough, you do you.
If anybody is experiencing it, then try to take some of the promo OLED HDR vids, from Sony, LG, Samsung, etc. (don't use Youtube) - take them down natively in their TS codec.
Here is an example with P11pro2021 natively. (YT below)
The unit has not been through the wringer with different custom-ROMs back and forward - at any time, came with the native CN/ENG with OTA ability and this video is with the FW it arrived with.
Here playing an OLED promo vid, (the LG OLED with the pencils) that I was stunned by when I first got my 7'serie LG OLED TV back in 2017.
Its called"LG OLED Art HDR UHD 4k Demo".. (469MB) Link:
LG OLED Art is a promotional video, in Ultra-HD HDR, for LG 4K TVs. Video Info: Resolution: 3840 x 2160 File size: 406 MB Duration: 00:01:21 Format: TS Codec: HEVC Frame rate: 60 fps4kmedia.org
Played from ext. M.2 SSD with MX Player Pro app on P11pro2021.
and you can clearly see the "black" is inky black, and completely summons with the bezels.
