C815K 65'' - V649. I have noticed some audio delay, but it is minor as I can either change the channel or if its VOD like on prime/netflix/disney+ I can just close the video and then resume it.

Dolby Vision seems to have changed. I usually have it at dark preset because it looked better, but this time the bright preset seems to look far better with highlights popping out while dark just looks washed out and dull, nothing pops out with the dark preset. Also this isn't just the preset itself, I have done some tinkering with it to make it look better IMO

Last - I'm not sure what is going on with Dolby Vision on Prime. It does not show up in the in-built TV app and neither on my firestick 4k. Instead, I get HDR10+ which isn't bad at all, but I would prefer DV.

Thank you
*****************
شكرا لكم

أهلا ،
لقد قمت بهذه التحديث (65P815):

- أجرى التحديث يدويًا باستخدام ZIP عبر USB (تم تنزيله من الموقع الرسمي)
- كان التحديث ناجحًا بشكل واضح ، وأعيد تشغيل التلفزيون ، وتحققت من الإصدار -> نجح التحديث
- قررت (كما أفعل مع أجهزتي بعد التحديث) أن أقوم بإعادة التشغيل (إعدادات نظام Android)
- حاول تشغيل إيقاف التشغيل ... وتوقف ...

الشاشة مضاءة ، ولكنها سوداء.

يبدو أن السبب في رسم توضيحي للرؤية الدائمة ...

حاولت استخدام التحديث.zip. يبدأ عند التعتيم. وضع الاستعداد العميق. حتى وضع الضغط على الزر الموجود في الخلف. ثم ضغط الصور الفوتوغرافية على الصور الفوتوغرافية ، ثم نشر الصور على الشاشة مرة أخرى في اليومض. حتى الان جيدة جدا. تشغيل مؤشر LED لتشغيل الشاشة ، تشغيل الشاشة مرة أخرى ، تشغيل الشاشة مرة أخرى.

هل لدى تشغيل مرة أخرى؟

شكرا!
لحل المشكلة بعد اكمال التحديث ويبدا بل الاقلاع اسحب الفلاشة من الشاشة ودعة يشتغل وتنحل المشكلة

I too have noticed a terrible degradation in the audio delay on v649 as well, its frustrating.
Though, I have some work around, not perfect, through different audio outputs from my PC.
Some changes to +10 to +50, sometimes +100, it changes... on the audio delay can help, sometimes.
Sometimes, pausing and resuming a video fixes it, for a little while..

Dolby Vision works same for me. Cant fault the Bright mode, looks stunning. Though I have always found Dark not worth it. Yep, its a little washed out on this version.
On Prime Ive seen HDR110+ popup in the corner, but it doesnt look like its doing much!?... Not sure.

In general, Im really happy with the picture quality as it is now. The audio delay sucks.

If the audio delay is better in v650 then Ill update (anyone have comparison between v649 and v650 yet?) otherwise I'll stay as the picture is the best ive seen yet

Um, were mostly English speaking here, unable to read that, sorry.

EDIT, this appears to be support provided to someone else.. Translated as (tahnks Mod)

Hello , I did this update (65P815): - Update done manually with ZIP via USB (downloaded from official site) - The update was clearly successful, the TV restarted, I checked the version -> the update succeeded - I decided (as I do with my devices after an update) to do a reboot (Android System Settings) - Tried to turn off the shutdown ... and stopped ... The screen is lit, but black. The reason seems to be an illustration of a perpetual vision... I tried using update .zip. It starts at blackout. Deep standby mode. Even put pressure on the button on the back. Then compress the photos to the photos, then post the photos to the screen again in a flash. So far, so good. Turn on the LED to turn on the screen, turn on the screen again, turn on the screen again. Do I have to run again? Thanks! To solve the problem, after completing the update and it starts to boot, pull the flash from the screen and let it work and the problem will be solved

    Be advised!

    I would suggest NOT to install this Android11 update yet, wait until bugs are sorted out.

    I have 50C715

    Firstly, great to see Android11 on its way! Awesome, cant wait for normal performance and functionality. Good job TCL and anyone else working on updates ;)

    Positive
    I have found that Auto Low Latency Mode (ALLM) is now available, I have not been able to test to see if it does anything yet​

    Negative - HDMI inputs DO NOT WORK
    I can not get my PC to display a picture. Have tried HDMI 1 and 3. The TV recognises the PC resolution but it can not find a signal. I also notice that the HDMI option for enabling 2.0 is no longer present in the options.​

    Digital TV channel scanning is not possible.​


    As most of use would be gamers on PC or consoles, this is not a viable update as cant play if you can not access the output of your chosen device. Im guessing DVD/bluerays wont work either, from what I can tell, HDMI is broken

    Trying to work out how to revert back to an earlier Android9 update, as I can't use my PC where I have the files lol. Lucky I have a work PC with me, just trickier..

    V900 works good on my TCL 55EP640...
    Thanks good.

    Its interesting then. 2 users having R007 (v900) working on xxEP640
    2 not working on xxC715
    1 not working in xxP615

    Is it better suited and made for only specific TV models? Eg just the EP640?

    The HDMI stopped working for me on this version as well... though my power on remote stopped working a couple versions ago. I had to use voice command. But then, voice command didnt work on new version. After downgrading way back to v453, my power still didnt work on remote. I tried repairing and unplugging tv, swapping batteries, even doing a factory reset and trying to pair remote in fresh setup flow... nothing worked until i found the exact process. I unplugged TV power, removed batteries, powered up tv, and did not place batteries in remote until TV fully booted (this was on TCL's troubleshooting steps) -- and it worked!

    Hello today i want Suggest & share TCL C715 settings for Xbox series x, at first never enable HDR for this tv disable HDR on xbox .

    also you need to enable in Xbox settings -- > ALLOW YCC 4.2.2 and use 10 BIT color depth this settings did not exceed hdmi 2.0 bandwidth also has less banding .

    tv setting must be

    SDR
    Game mode : ON for lowest input lag
    brightness: 100
    Contrast : 100
    Dynamic Contrast : Low or Hight ( I prefer High )
    local contrast : low
    Black stretch : 0
    Dynamic Backlight : off
    color : 45
    black level : 48
    Sharpness : 0
    color space : auto
    color temperature : -1
    Gamma : 0

    HDR : X not good for this tv

    with this settings tv gets darkest blacks as possible and brightest whites , picture are fantastic clear and 3 dimensional, fantastic result on forza horizon 4 and more

    I 100% recommend to try this settings on this tv and xbox if you want bright and Crystal clear image

    Another Argentinian here.
    As I got tired of waiting for the OTA to appear, with my adb logcat running, and it never did ...
    I thought: "why don't I edit the ota v213 url to see if it works?", and it did. :p
