[Lenovo P11] DaneLaw:
As I tried to explain in #138 the thing you're referring too and the picture you repasted in #104, looks a lot like the ZUI transparency feature where things underneath will shine through and almost give that old IPS-blooming-effect, but on P11pro2021 it looks (as far as I can tell) like it's with intent, and a feature of the Android skin Lenovo are using.

Are you sure it ain't that "ZUI transparency feature" you mistakenly take as "grey problems" as you expressed above to the picture #104 that was posted that certainly looks a lot like the pictures I showed of the OS transparency feature? in post #138

also why I hope'd you would demonstrate it.? (as you mentioned a few months back you would in #132)

As then I could try to replicate it and see if you got a bad batch, or it's a revision issue, or it's common?

- as it ain't magic and if there is problems with grey toning. you would see it with finer and finer grey slide-lines or in different grey or black scales like the examples above, but in the few tests I have made, and where such things usually would be elevated, - I don't see anything, quite the contrary, I'm very impressed with the OLED display Lenovo er using and it blew my mind the prices this tablet is being sold at, like 350 USD, but it also looks like it originally was sold at a way higher CN price back in the day

- and here in the west, the older little brother P11pro2020 (J-706) just entry version' is still from +655 USD on Lenovo dk (Denmark) (4299 DKK) so the J-716 would likely be +750 to 850 USD if Lenovo had released that model in the west.(no wonder that people turn to foreign markets, with such price mockup.

I also have Samsung AMOLED displays, so I can compare one to the other and my girl's parents have an S7+.

The E4 is an older AMOLED blue-stripe panel and certainly also has its weaknesses and almost no change from E3, likely also why we are seeing a new generation E5 in the second half of 2021 and now in the start of 2022 and on Tab S8+ and Ultra and numerous third-party mobiles.

Personally, I prefer the Xiaoxin ability to show red. often a problematic color to get deep and vibrant as it is choking into orange..

I'm also impressed by the Xiaoxin P11pro2021 DC dimmed panel and its brightness ability.

I'm seeing some of the highest brightness values I have seen on any tablet on the Xiaoxinp11pro2021 and way higher than fx P11pro2020.

with the brightness sliders it tops out a tad over +600nits.. like 630nits, but if you activate the extreme brightness effect and trigger the lightsensor. it goes up to just under 900nits. (that ain't too shabby in full white)

- and it does inform you on the screen when it goes into this extreme brightness mode and also when it goes out of it. (the max seems to be around 900nits and I don't know how long it can sustain it)

Example..

plain sliders. (a tad over 600nits)

As a person that is fascinated by display technologies, I love the fact that it ain't a very common OLED panel in the P11pro2021, as we have seen the Samsung E4 AMOLED panel in so many products and also in sub200 budget tablet brands, like Alldocube, and Chuvi, ... the Samsung E4 panel is very common and I reckon most people have an item with that AMOLED E4 tech in house and why I find it interesting to get access to other manufactures OLED technologies and being able to compare variables and pro & cons.

The biggest con on these Lenovo / Xiaoxin P11pro2021 / P12 is the OS.. kinda half-baked from a western viewpoint, hence the lack of western release - but some things the ZUI-OS is actually doing better than my Samsungs DeX Tablets.

fx video-out looks to be in 4K.. my LG 4K OLED TV (2017) does list it as a 4K signal but in like a 4:3 ratio.. where I otherwise the max are 1440p on Samsung.

Was also pleasantly surprised to see the wireless-display interaction with LG OLED TVs and the wireless-display quality and the LG remote control-pointer function as an android mouse..

makes it a blast to stream Magellan & Wondrium and the other science stream channels up on the big screen, without cables.
