Could anyone please check the issue with the adaptive luma being always set to "on" when switching between hdmi's?
Thanks!
Thanks!
Xiaomi to launch Mi TV Q1 75" on 23rd March - QLED, 192 Zones, 120Hz
- Thread starter aditya2603d
- Start date
Not happening with me. I have adaptive luma turn off and and swapping between hdmi inputs does not turn it back on.
volume output on optical is lower than ARC. thats the reason I use arc with my old pioneer VSX424 receiver.

To be honest I have not checked or come across the 1st point of adaptive luma control. Not a geek and also not sure on how this really affects picture quality . Never actually bothered to get into finer details as long as the PQ was to my liking ....a quick question - Does adaptive LUMA being ON or OFF affect PQ ?
For the 2nd point , I agree with you . Sound via optical is low than HDMI for reasons unknown to me. Most likely could be s software bug with the TV. Ideally for old receivers which at least support ARC try doing a passthru from HDMI Port 2 to AVR . Sound is ok. If you use a FS or Google Chromecast 4k connected to HDMI 1 or 3 of TV , the sound output is even better (in passthru mode) thru AVR.

Are you sure?, I mean...just to clarify my point:
The problem is not that the "label" in the menu is not set to off when swaping HDMI's or from anywhere to an HDMI, actually the label in the menu says it is "off/disabled", the thing is, the effect is actually enabled even though it is labeled as disabled. It can be checked by enabling (then nothing happens becasuse it is already enabled) and then, if you disable after, you will probably see how the image changes (now it is really disabled).
To make this I recomend a still image with blacks on it.
Is that what you checked?
thanks!

Of course it affects picture quality. Everything will look much darker and it will mostly crush blacks...it MUST be disabled for a serious picture adjustment. In PS5 it is terrible and every single time I connect with the PS5 HDMI I have to enable and then disbale the effecto to get rid of it...is making me sick!!!
I have the exact same problem every time I turn on my playstation 5. Don't think the problem was there before the update.

For me it was before the last update so pretty much the same for you. This is a SERIOUS bug, how can we make Xiaomi to awkonwledge this?
Hi,
Do you know how to downgrade the firmware? I've got 5135, and I see some lag while streaming Netflix, sometimes Youtube... as reported by other users.
I would like to downgrade it to 3270. When I try it through recovery mode it tells me it's not an update (of course it's not) and I can't. Any suggestions?
Or any news about a new update?
Thanks,

Thanks,
I disabled a lot of background android system apps using ADB and also limited the background apps to 4 maximum (via developer options in android)
that almost completely removed the lagging and stutter in the native apps .. I still didn't find a solution for my yellow push however (on all my HDMI inputs in 4K UHD )
If someone can tell me how I can adjust the color settings for the Native apps like netflix etc.. I would be very happy.
I can't find it ...color adjustments only work for hdmi inputs it seems also no color adjustment possible in UHD profile.
I also tried connecting a Amazon FireTV 4K Max stick to the TV but then I get bad Netflix quality compared to the native app !
Netflix on the FireTV stick is not using 4k resolution , but I've set all my hdmi ports to hdmi v2.1!... (HDCP2.2. issue?)

I bought the TV 2 weeks back after reading this thread and I am coming from 7 years viewing LG OLED 55B6T
the TV had permanent burn in issues and screen loosing colour accuracy due to this. watching movies for 5 years made it have burn as cinema scope - ribbon band inbetween and messing up.
had to sell for 5K while I bought it for 2L in 2016 LOL.
I have decided to not buy a OLED after this bitter experience.
Coming Mi TV 75 QLED, the quality is acceptable for me, coming from OLED. not a deal breaker for the price.
Blacks are pretty good, I would say in Bright screens, it doesn't match up in clarity with OLED (its blown up white and looses details)
especially noticeable in Sky and Sun scenes in TOP GUN MAVERICK vs a OLED
overall I am still happy for the price and size of 75.
(Bought from Mi Directly, and I Paid 1.39L with 9 months No Cost EMI and 2 Years extended warranty free, which gives 3 years full coverage)
I find following settings good for my taste
1: Movie Mode or HDR / DolbyVision DARK modes
2: Noise and Motion settings OFF
3: Local Dimming, Dadaptive Luma,Local Contrast Control ON
4: GAMMA - DARK
5: HDMI Range & Colour Space - AUTO.
For HDR and Dolby Vision, I set Backlight to 90, Contrast @50 (rest settings at default)
for normal modes/4K I set Backlight to 80 and even 70(during night) as TV is very Bright, Contrast @40 (you can goto 30 also, if you find it brighter)
Here are some pics

I checked again properly, you are right, adaptive luma turns on automatically on every boot even though the label says 'Off'. I have to click on and turn on and again on turn off to properly turn it off. If I change HDMI sources, adaptive luma again turns on again even though the setting label says off.
Adaptive luma makes things very dark and kills a lot of detail. I'm surprised this isn't fixed yet.

Thanks for your time checking this!, glad to hear I'm not alone, so then we can conclude this is a common issue. What really puzzles me is how on earth this wasn't noticed by anyone?
, as described, it is glaring obvious that the blacks are crushed with the luma enabled and that's how it looks as soon as one changes from anything to HDMI or between HDMI's.This should be reported to Xiaomi. To me, the most critical bug!!
Honestly speaking the TV was a good buy, all the hardwares are really good for the price I paid but the gobar software is shit shit as shit they should have used stock android, their so called techy shit Sandeep is so stupid.Thanks for your time checking this!, glad to hear I'm not alone, so then we can conclude this is a common issue.

Actually All TV's should be pure dumb displays and nothing else
- let people connect consoles/ set top boxes etc
- saves cost
- removes unnecessary hardware components
- still wonder why they still come with TV tuners this age and time.
Hope some brand comes with Dumb Displays with less cost and purely concentrating on display performance.

Agreed, I bought it at 1.1L at launch and panel is quite good. I use the shield pro so no real issues except ARC and adaptive luma. both I manage through a macro on the harmony remote so it’s a button click to toggle off and on.

Guys at about 144k with 3 yrs warranty at 9k, its working out about 135k today.
1. Are there better options for 135k? Over all recommendation to buy this tv pls? I will be upgrading from a mitv 55 inch 4k. (Presume it's an led tv)
2. Does the mitv 75 inch wall mount well? Is it the same mount as the 55 inch mitv? Can it wall mount on same bracket used for 55 inch mitv without having to redo the bracket?
3. If i have the firestick or the shield in place does the tv sw come in the way of user experience in anyway?
4. What is the local adaptiv/ luma issue ? Can anyone point me to a relevant message or page to understand the issue?

1: @135K its still a good deal, you will get Vu and Hisense for 10-20K less but they panels are low specs than miTV so its still a bargain
2: Swivel Wall mount could not hold weight and was angled down and had to make them install normal mount. the 55inch normal MiTV mount should work for 75 inch too. anyway the installer guy will install what is recommended not recommended to experiment here, given its a big tv
3: i use Apple TV and use MiTV as dummy display and no issues, it works seamlessly
4: Adaptiv Luma makes black levels better, some dont like and feel its not good and disable. I like it though.
the issue spoken in this forum, is the setting comes back ON if disable, if you switch the TV input.
since i use only Apple TV and always use only 1 Input and never change and also i keep it ON as i like it, its not an issue for me
in my view its not a big deal of an issue, just a small niggle for folks who really find luma bad, for me i feel its good. better back levels
