[Lenovo P11] DaneLaw:
I reckon it went over your head.. the use of 900 nits brightness on Lenovo P11pro2021 comes in handy with certain use-cases in bright sunlight - as you hopefully can conclude on your own.

instead of making a braindead example, like "who would be watching movies with a flashlight to trigger maximum brightness"

c'mon bud.. a tablet can be used for other things than just watching movies.

The 900nits maximum brightness feature, is intended for bright sunlight, if your using the tablet fx outside, or in a car, - or as I often do, as a 1600p OLED screen for DJI drones, - the native sustained brightness is at 625nits..

People have different use-cases for their tablets, not only watching movies, and it's a nice feature to have on mobile items like tablets, and mobiles that the item can peak brightness in certain well-lit environments..

I haven't noticed any of these things you referring to, but I'm also running native CN OS and haven't put any third-party ROMs on it, or flashed it back and forward with different ROMs, and many models are being sold of this unit - are being sold with third-party multilingual ROMs. (not sure if your unit is one of those)

But I was trying to help, and I kept backing it up with videos. and pictures and examples... simply to demonstrate where it excels and where it doesn't - but it needs to be repeatable.. just claiming I get some issues in something I'm watching, is a relative as it comes and not easy for others to check or validate, as it can be down to numerous things., and I don't recall I have seen any examples from you..

That you have grainy "reds"....don't take for granted that it's the same for all other people with a P11pro2021 - with your statement. - // "you like OLEDs and you can't even see the grainy reds".

If you take a screentest-app.. and chose red and even dial brightness back and forward..does it look solid, if it does, then it ain't fundamental.

You could clearly see how coherent the RED looked in a side-by-side with 1600p AMOLED panel.

So far you haven't delivered even one example to repeat these things as I recall - so it doesn't make much sense to debate it further if there are no tangible examples.

you DID state that you would show an example.. didn't you??. (have I missed it, then my bad??)

and you even stated it was a "pentile display", which I explained to you it wasn't and Pentile displays are a Samsung trademark, and this wasn't a pentile display as per se' as it had an equal amount of RGB subpixels..

The biggest drawback with these Lenovo tablets is the OS.. which seems kind of half-baked IMO.. the hardware is top nudge' fronting flagship-level.. not least for a sub 350 USD device delivering 725k in Antutu and IMO the ideal framerate for different use-cases, like video or gaming with 90hz for an SD870 Soc with a DC dimmed RGB OLED panel and a 1TB SD storage slot.

Certain media players can cause problems with HDR metadata, not least when this device also supports dynamic HDR (frame by frame) and not just static HDR.. again I don't know if flickering can be down to that. or the mediaplayer your using.

- at the end of the day, it's Lenovo.. it's not like their firmware & software is the gold standard.. often quite half-baked... even products intended for the western market can be a hard sell. -. it's the low price that makes this product stand out.

Just check the colorcharts for the differentOLED-tablets, and as I showed in my colorslide-video the color reproduction that is being delivered with this Lenovo/Xiaoxin 1600p RGB OLED in P11pro2021 is better than what I'm seeing on AMOLED. E3, E4, E5.

Sadly Notebookcheck did not check the SD870 variant but they did check another Lenovo unit. (P11proSD730) that seems to have the same 1600p RGB OLED display (just run at lower framerate and lower brightness) and they also saw better colors on that RGB OLED than on Lenovo P12's E4 AMOLED.

_Lower is better_

AMOLED E4 blue S-stripe panel in Lenovo P12pro.

P12pro dE2000 3.43

P12pro dE2000 max. 7.25 (wow)

P11pro dE2000 1.8

P11pro dE2000max 4.2

The P12pro color check scores are not good, they are around the 1350p IPS in Yoga Pro13, but that is IPS.

even Samsung own flagship Tab S7plus own AMOLED E4 panel. are delivering worse colorcheck-scores (dE2000 2.4) than the 1600p RGB OLED panel that was in the P11pro (dE2000 1.8) a dE2000 at 1.8 is flagship ApplePro mini-LED level..

And it falls in line with what I saw when comparing the colors of the RGB OLED in P11pro2021 vs AMOLED ..

the p11PRO2021 RED subpixels does seem more coherent then on AMOLED. https://tinyurl.com/2p9d63yw

Im quite impressed by the 1600p RGB OLED panel that are in P11pro2021 and its even beating Samsung tabS7+ and is also ahead of Apples current tablet flagship Ipad Pro 12.9 MiniLED on color check scores, and when you then have in mind - it's a sub 350 tablet.

- not to shabby 90HZ DC dimmed 625nits 1600p RGB OLED panel Lenovo is using in the P11pro2021.
