I am having a specific issue with my X925. When Dolby Vision content starts playing, the image changes to a washed out full brightness version of DV IQ. It is not until I go into picture settings and change Dolby Vision IQ to ‘Bright’ or ‘Dark’ then back to IQ that the image looks correct. I have to do this every time. Does anyone have any suggestions?

When playing Dolby Vision, adjust setting for your need and in pic setting set ..Apply for current input.

I have a question regarding the C825.

What version miniLED panel is it using? Peak brightness? Black crush issue?
TCL panel version you can see in service menu...type 1950.
Peak brightness is arround 1000,you can found in many reviews.
Black crush issue,I don't know.

Bro, no need to post same thing every 2-3 days.
2021 TCL models for UK are all Android 9 and differ from Europe spec and firmwares.
Since a month ago, TCL stop posting (and relocated) firmwares on they known server.
At the moment no clue even for older TCL models ,specially not for K...UK models.

Sorry I was asking because if you look at the CPU specs and platform it does not seem to be the specs for that model and in Amazon discription. Just wanted some who knows a bit about TCL if then can tell me the specs in the pics match what the Amazon discription for 65C729K 2021 match as it didn't seem to , to me.

As I posted earlier, UK 2021 models are different then Europe models.
UK.... C728/9K and C825/6K ....models are with Realtek SoC RT51M and NOT with MediaTek 9615 (as Europe models).
For better understanding read in this forum....

Hi @stasiof! I just bought a 75C728 in Saudi Arabia so I guess it is the EU model with MT9615. I updated the TV to latest v083 as was posted by you and the image quality appears to be dark overall in HDR/SDR or even DolbyVision content played from an External HDD using DV Bright setting.

I also have a 50C715 model which has overall better image quality with proper highlights in DV videos compared to C728 which surprises me as I was hoping the new model would fare better.

Did you notice this behavior with your TV on v083 as I didn't test anything on its original firmware which it came in (v027)

Thanks for all your support on the TCL TV's you've been giving.

In setting...check Advanced/ Brightness and play with Gamma + or -.
In system, I have sports, game and shop mode disabled.

    Is same platform R51M.
    In Philippines, India and Brazil.... P725 and C725 are coming with R51MT05 (Google TV) firmware,out of box.
    Read more:

    Anyway, you can always flash back to R51MT02, with IMG file.
    (not valid for UK "K" models, because there is no IMG file)

    Taken from test V418 IMG....hardware support:

    Hi!

    I just recently bought a TCL 55C725 ( in Spain ), it came with R51M v246 installed. I've been having tons of problems, specially in Dolby vision and game modes where some sort of backlight auto dimming is on even if everything is off on the settings ( including the secret menu where both the eco mode and DBC are off ). After reading around, the only possibility that I have left ( as far as I know ) is too try to update the software. When I try to update through the network it says it's the latest update. When I go to the European website it points me to v256, but reading this post i can see there are plenty of newer versions. I'm new to updating manually my TV, although I'm confident I can do it.
    I want to ask: what's the latest, most stable and recommended update for my specific model (55C725) ?? v267?.. or??

    Many thanks in advance!!
    I am completely happy with v267 which I installed locally (also, not OTA) over v256 which was preinstalled in my 43C725. However, I am not using any sound passtrhu since I am using my tv without any external speakers or amplifier. Therefore I cannot tell you, if passthru works OK in v267. If you run into any problems, you can always try v256, v282 or those custom firmwares to which you can find a download link in this very forum...

    There are certain regions where OTA is not available for years & neither on TCL local support. AP region hasn't. NA & EU are lucky though where updates are available via OTA or local TCL has it on support page.

    Hello everybody. I recently bought the TCl 50C725 and I am satisfied (especially after the adjustments I found in this forum; I followed the previous model C715).
    For the Italian market there is no PVR and Timeshit; as you indicated, I would like to try to change the Project ID of the TV (currently 6446).
    Compared to what I found here on the forum, now the Project ID is with 4 digits instead of 3.
    Also in the list of TCL Project ID sheets (let me thank stasiof for the great work he does to the community) clearly I don't find my TV (too new) and I only find 3-digit Project ID.
    Do any of you have experience with the Project IDs of the new 2021 series (C725)?
    In the meantime, thank you all for the great job you guys do!
    For 2021 models Project ID is not released yet, so need the time to be released and change Project ID.
