Sorry, what is this "Local dimming Off Off"?

Maby You're wrong. Check again
[Philips, Sony, TCL Android TV] leichenlager1980:
This is the setting under Picture/Advanced settings/Brightness settings/Local dimming (2nd point over Gamma)

I set it off for SDR/HDR/DV
[Philips, Sony, TCL Android TV] kohanyi.robert:
On the TCL Telegram discussion channel a user using the M999 V2 firmware posted a problem about a week ago.

With local dimming set to high the following video (probably other SDR content has this too, but this could be a good reference) looks oversaturated/clipping happens, when local dimming is off it looks natural (more details are visible). See attached pictures and observe the face of the man wearing a baseball cap.

Using M999 V2 the same happens for me on my C745X2. So this is an issue with V2.

Could someone using M999 V3 verify, make a picture when local dimming is off/high, using the video as reference?

Thanks in advance.
[Philips, Sony, TCL Android TV] zenix123456:
This must be on/high, especially in hdr
[Philips, Sony, TCL Android TV] kohanyi.robert:
Thanks for the effort @Rafy1991. Based on the pictures I can see some difference between the two, but can't really judge whether this feature of the TV have been improved in V3 compared to V2 based on this. Inconclusive fo me so for now I'll stay on V2 because this is my only beef with it.

What's your personal opinion, did turning on local dimming made details on faces disappear/go flat?

Thanks for testing V3 🙏
[Philips, Sony, TCL Android TV] Rafy1991:
În my opinion on high settings image you can see more details, on off is too dark
[Philips, Sony, TCL Android TV] Rafy1991:
look at the blue curtain behind the sofa
[Philips, Sony, TCL Android TV] kohanyi.robert:
On the pictures you took with local dimming off the picture is a bit washed out for me (too much brightness), the other is too dark a bit (especially the curtains).

Again, I'm unsure based on this, I'm thinking maybe this is due to the picture quality of the photos you've taken (no offense, really, thanks for chipping in, this is how it is when you take a photo of a screen I guess, depends in the camera, lighting, etc.). Can't decide whether it's better this in V3 compared to V2, but certainly not worse. So maybe I'll take the plunge and update, but I'll take before and after pics :)

If someone's reading this with stock V028 firmware please do take the time and take pictures of this settings for reference. Thanks :D

If anyone interested I made pictures on my C745X2 set using the aforementioned video as source setting local dimming to off/high using M999 V2 and after upgrading to V3. Same thing happens, this is not fixed in V3 (if this is considered as an error, I think it is personally).

I tried a factory reset also, in hope that it'll set things straight to no avail. Same happens. Let's hope V4 will do the trick.

For reference I took screenshot in the video at 4:44,

T653T01...testing recovery IMG (PKG) file.....:D
[Philips, Sony, TCL Android TV] Rafy1991:
What firmware version have on this img file?
[Philips, Sony, TCL Android TV] kohanyi.robert:
Turning it on (setting it to high) distorts colors for me. Setting it to low is acceptable. The most significant effect is between off and low, from low to mid and mid to high blacks won't get significantly more black IMHO.
[Philips, Sony, TCL Android TV] kohanyi.robert:
Yay, is this the V028?
[Philips, Sony, TCL Android TV] zenix123456:
Maby your set is defective and you should turn it back. The higher local dimming the better blacks
[Philips, Sony, TCL Android TV] kohanyi.robert:
Well, maybe, I think the test updates "ruined" this feature, or ar least altered it, I'm not sure. On the other the test firmware fixed my "green dot" problem in Game Mode. So it's a trade off. Others had the same problem. Low dimming is perfectly dinw for me, but I'm monitoring changes ro this feature in upcoming test versions.
[Philips, Sony, TCL Android TV] 001248/776:
That's the TCL world you entered into - one thing gets fixed, two other get broken.

But still - apart from firmware bugs, you want local dimming to be set on highest setting in any miniled tv, especially with quite large amount of zones like TCLs have.

Also - its super sad that years pass and TCL still releases tvs with firmwares ridden with bugs and basically non-working basic functions...
[Philips, Sony, TCL Android TV] kurtschmeichel:
R090.000728 it seems.
[Philips, Sony, TCL Android TV] kohanyi.robert:
I'm not sure that setting local dimming to high is a bug actually. If you read this thread on Reddit a Sony model has a similar issue. So, maybe on the original firmware (V028) this was the case, only I didn't notice it, or local dimming was set to low/medium, who knows.
[Philips, Sony, TCL Android TV] stasiof:
Seemse forget about V028.

Two times should get, but person next day disappear.

Yea, is R090 .pkg file.

Hello,

I'm on a 75" C745 X2 (Pentone 700) with V028 Firmware

(still not updating, because I'm not brave enought to risk a deterioration in image quality ... Waiting for all advices to be good)

Here the pics of V028 :

(local contrast is set to disable for the 2 firsts images)

Local dimming high :

No Local dimming :

In real situation, with my eyes, I see no difference in skin tones between Local dimming stopped and Local dimming High with V028

Local dimming High + Local Contrast High :

(Not what you asked for, but i see a deterioration in faces skin tones here)

[Philips, Sony, TCL Android TV] firefly2023:
Hi everybody!

I couldn't find a clear answer reading the last few posts so I'd like to get some confirmation.

Is this lately released IMG file (T653T01) usable for the C805/C845X2 and X8 (Pentonic 700) or is it only suitable for the older chipset (C845X1)?

Thanks in advance!
[Philips, Sony, TCL Android TV] kohanyi.robert:
Thanks for the comparison. Hard to tell, but

Based on stasiof's message

> T653T01...testing recovery IMG (PKG) file.....:D

it's only for Pentonic 700, T653T01 platform.
[Philips, Sony, TCL Android TV] firefly2023:
So where can I download this file, please?

I've only found a link for the following firmware on page 28:

The recovery img stasiof mentioned?

It's up to him/her to upload it somewhere.
[Philips, Sony, TCL Android TV] ThePS4Gamer:
Hello, @stasiof!

What should I install? M999 test 4 vs recovery IMG file? I am concerned if I ever get OTA updates because I installed test firmwares.
[Philips, Sony, TCL Android TV] firefly2023:
AFAIK the IMG recovery file for the Pentonic chip hasn't been uploaded yet. The latest link doesn't seem to be the recovery version.

Btw, I really doubt that you'd reveive an official TCL update OTA no matter what type of firmware you use.

At least in the EU region TCL is well-known for not updating their TVs ever.
[Philips, Sony, TCL Android TV] stasiof:
Today I will upload R090.pkg recovery file on telegram....:D

For new users.....

All firmware posted is from TCL.

(and TCL has 8 independent regions...EU, ME, AP, AU ,etc...,

but is doesn't matter as firmware is global).

So, less asume , less headache.....:p
[Philips, Sony, TCL Android TV] ath156:
To have such an "img" file of course is very important.....and of course Thank You for this.:)

What this number "R090" means? As most of us still have the "official"/"stock" firmware version 028 (European?).....how is this compared to R090? If someone installs R090 will he be able to update to something newer? Or he has to install something with a larger number than 90?

As I understand it, we will never be able to roll back to 028 (until someone or TCL itself decides to leak it). Correct?
[Philips, Sony, TCL Android TV] stasiof:
Why you need V028, in first place?

TCL (EU) will probably soon finally place new update on they server ( I read info...end of this month).

So, after new "official" update arrive ,V028 will be history.

Installing recovery R090 will enable you to install any OTA, higher that R090.000728.

From R090 to install any OTA, will need again to rename zip file, either from V (official update) or M (test versions)...... to R version.

Take a note, that official EU TCL service, also installing R090 or R094 version after TV is back from service.

Crossposting here too, maybe xda has more PC users:

Can someone confirm that newer than 028 firmwares fix 4:4:4 chroma in SDR with game mode enabled?

Bought 50c805 and counterintuitively 4:4:4 chroma works just fine with HDR enabled in Windows regardless of other settings - currently 4k@120Hz, VRR, 12bit.

However, it doesn't work in game mode if HDR toggle in Windows is off.

The only way to make 4:4:4 work in SDR is to disable game mode (& disable GSync). Then it works no matter 60/120Hz or 8/10/12bit color.

Basically:

Game + VRR + HDR = 4:4:4

Game + VRR + SDR = 4:2:0

Strange bug.

Here's a test pattern - save it to disk and open in image viewer if using scaling in Windows other than 100%.
[Philips, Sony, TCL Android TV] kohanyi.robert:
Installed the recovery firmware posted by stasiof on my TV (C745X2)

1. Still fixes the "green dot" problem when in Game Master/Mode.

2. Fixes the local dimming issue I had: with this version when I switch between off, low, mid and high the effect it has on the picture much less adverse: from off -> low is the most noticeable, from low -> mid and mid -> high it's only barely noticeable.

I think/feel this is how the original V028 firmware was behaving for me with regards to the local dimming stuff, so I'll go with this (my main issue was the green dot problem). My guess is that in the newer test firmwares the "low" local dimming setting corresponds with "high" in the older ones and TCL engineers are playing with how "far" they can raise this without problems. In the test firmware even if I set it to low it still felt off in menus and all around - less noticeable in moving images, but it was bugging me in the menus.

One other difference I noticed between the recovery and 1st test version: there's no "green leaf" icon beside brightness and other options.

hi all

i recently bought a tcl c845 75inches tv.

I'm generally pleased but I'm facing a major problem. the TV is unable to lock the 24p when playing material from an external player. From NVIDIA shiled for example playing with Kodi or with plex, i have continuous drop outs every 1-2 seconds. At 60 it plays perfectly. if I change the setting in Kodi or Plex "adjust display refresh rate" from "on start/stop" to "off" then I don't have any problem, but that means I lose 24p. but I prefer to watch my movies in their original 24p format.

any thoughts or solution?

Hi everyone. I hope someone understands something. On my TCL Android TV, the optical audio output to the amplifier, if I transmit from a TV source, works perfectly but if I transmit from a connected USB hard disk, it presents a deafening hiss. I noticed that this happens when I select the source from the remote control but, if I select the film from an Explorer file and probably open it with another media player, everything works without any noise. I can't figure out which media player the TV uses by default because I can't find any options. I thought that by finding this player and changing it it could be solved. Can you help me?
