Hello, I just bought TCL 55C635. It automatically updated to firmware v477 on first start via OTA and I then soon updated it to the latest v501 using IMG firmware.

I noticed 2 problems with this TV:

1. Videos played on it (thru IPTV apps, Netflix etc) are not very smooth, I can see considerable stuttering in movement. It seems it is much smoother when using the same apps on Fire TV Stick (4k Max) connected via HDMI, but only when I have TV Stick's output set to 8bit colors - if I set 10 or 12bit, it stutters too. Is there any way to reduce that stuttering? Or is it caused by too slow CPU in the TV, that doesn't have enough power to play 24-25 fps content on 60 Hz TV with the postprocessing it has, and there can't be done much to fix it?

2. I noticed that TV has kind of yellowish tint, like if the white balance is not set correctly and white tends to be rather yellow than white. It is especially visible with lowered brightness. Is that normal? Can that be fixed somehow? I didn't test the TV much with the original firmware, so I am not sure if that could be caused by flashing that v501 IMG FW, if it could wipe some panel settings,etc, or if it was yellowish before that already..

My new 50C635 (still keeping C715 :D) came with V496.

After debloating (disabled) all unused apps, disabled power saving in streaming apps, update all apps to latest version, set 4 different picture setting,TV works as I expected,

Not gamer , so can't comment on this.
[Philips, Sony, TCL Android TV] AvGear:
Please let me know if there is an update regarding this, I also experienced the same thing on the 4xx firmware
[Philips, Sony, TCL Android TV] tonarii:
Hi, i also can't activate the Game Master Mode with my PC, do you have new informations about that ?

Also regarding your 144hz issue, have you looked at the color depth ?

2160 p 120hz 12 bit

2160 p 144hz 10 bit

On the Rtings test for the North American version of the tv, they also had some issue with 4K 144hz on an Nvidia card, but no problem with an AMD card. I think that will be fixed if it's from Nvidia.
[Philips, Sony, TCL Android TV] lapist:
I also found that I can't activate Game Master with my Xbox Series S when I enable VRR (TCL 55C635 v501), without VRR I can... Strange.
[Philips, Sony, TCL Android TV] testguest:
Hi guys, could someone owning a C635 or C735 confirm if it is possible to rotate the screen 180° in the service/factory/hidden menu?

I'd really appreciate your help since I'd like to avoid ordering the TV blindly and trying it/sending it back if it's not possible.

I know, it's a weird use case!

What hdmi port are you using? Ive same tv but with series x and works great
[Philips, Sony, TCL Android TV] lapist:
Is it normal that I have panel name null in service menu on 55C635?
[Philips, Sony, TCL Android TV] lapist:
I tried HDMI1 and HDMI2, but it was the same. What firmware version do you have?
[Philips, Sony, TCL Android TV] extream87:
@lapist Im on V8-R51MT05-LF1V501.020739

HDMI 1 is 2.1 port.

Do you also have activated vrr on game master settings? You only need to enable vrr 1 time. Game Master allways need to be activated mannualy. You can press 3 lines button and enter on game menu also to activate hgig.

Recently acquired a TCL C635i, not exactly sure what the "i" letter stands when compared to the C635 model. Very happy so far, just got a couple of questions, this model doesn't seem to have any LED Motion or Black Frame Insertion equivalent present in other TCL models? There's a "Boost" option that can be changed from ECO to Fast, but not sure if that's related to BFI.
[Philips, Sony, TCL Android TV] stasiof:
Maybe firmware ?...just guessing....

My attached....
[Philips, Sony, TCL Android TV] dah145:
Same for me
[Philips, Sony, TCL Android TV] lapist:
Doesn't seem like firmware - I just tried reflashing v501 to v483 via IMG and also null.. Upgraded it using OTA Zip to v496 and still null.

I am wondering if that could be related to yellowish tint of the screen, if it can't set parameters of the panel correctly. Are your whites perfectly white, or also a bit yellow?
[Philips, Sony, TCL Android TV] lapist:
I tried, but it doesn't seem to work. First I enabled VRR in Inputs settings, then game master shows VRR as enabled and option in Xbox settings to enable VRR is unlocked. But when I enable VRR in Xbox settings, game master turns off and it can't be enabled again. I tried various settings of video output in Xbox, enabling/disabling 120 Hz DLG, but no change. Does VRR with Game Master enabled works for you in Xbox GUI, or it can be enabled only when a game that supports it is running?
[Philips, Sony, TCL Android TV] lapist:
I reflashed v483 and upgraded it to v496 using OTA ZIP, set everything again, then set limit for background processes in Developer options to 3, and it seems that the stuttering is almost gone. Hopefully it will stay like that 🙂

EDIT: Unfortunately it stutters again. Perhaps it depends on app, tasks running in background, or CPU temperature.. 😔
[Philips, Sony, TCL Android TV] extream87:
Xbox gui works for me. Also when i enable game master in the top right corner appears port, reso, gamemaster. I will post an picture later.
[Philips, Sony, TCL Android TV] lapist:
OK, just ensure that you have VRR enabled in Xbox Video settings, in the same time when you have Game Master enabled..
[Philips, Sony, TCL Android TV] extream87:
Yes i have. Allow vrr and vrr on on tv
[Philips, Sony, TCL Android TV] CyberPhoenix69008:
Hello, from france. I buy the 50c735 , so i give you my return. First time i have problem with automoatic brightness. Brightness was not sync with the scene (0.5 sec delay)so i did a reboot /with switch off the power cord. The problem is now solve.

Secondly, i have stuttering with 4k/hdr scene in app on the tv (amazon prime) i call tcl and do a complete reset and it’s do nothing… i think the processor on tv is not good / or the refresh rate of this tv is so bad (60htz)/ or maybe some bug.

I have an apple tv hd , it’s better with movement optimisation on tv at 10. I buy the 4k apple tv soon so i give you some new information soon. An other problem was the CEC with apple tv work to on the tv but won’t off (tcl has no solution).

So i try an echange with my supplier to the mod 55c735 (120htz) maybe it’s better.

Finally i don’t find homekit /airplay on this tv . Maybe it’s the french version don’t have it ? I’ll try another language if it’s activate it.

Some new after 20 December if a recive the 55c735. Hope it’ll be better
[Philips, Sony, TCL Android TV] lapist:
I checked the service menu on my C635, but didn't see such option..or at least nothing was clearly named like that, but there is still a chance that it is hidden somewhere..
[Philips, Sony, TCL Android TV] extream87:
@lapist do you know if we can check if the tv is on 4:4:4 or 4:2:2?
[Philips, Sony, TCL Android TV] lapist:
@CyberPhoenix69008 Does 50c735 have the same poor Realtek CPU like C635 and 60 Hz panel, while 55C735 has faster Mediatek CPU and 100 Hz? If so, are there any differences between 50C735 and 50c635?

Anyway, on my 55C635, I got smoother system when I enabled Apps Only mode in profile/user settings and limited background processes to 2-3 in Developer options. Videos played in Netflix, HBO Max, Disney+ and Amazon Prime (including 4k and HDR, but Dolby Vision content is not so smooth) seems to be smooth now, but I get a lot of stuttering in IPTV apps (which is 25 fps content fullhd ). Those are smoother from my Fire TV Stick Max 4k. At least CEC works fine for me with Fire Stick.

Did you try updating to the latest firmware from the Telegram group?
[Philips, Sony, TCL Android TV] testguest:
Darn it, thank you very much for checking.
[Philips, Sony, TCL Android TV] lapist:
Unfortunately not, I didn't find such info in service menu nor developers options in the TV.. But I would be interested in knowing that too 🙂
[Philips, Sony, TCL Android TV] CyberPhoenix69008:
I don’t try to update firmware for now , I’m waiting the 55c735
[Philips, Sony, TCL Android TV] pingpong100:
Hi, I recently bought a TV model C635 - 55 inches. The TV works properly, but when I connect an xbox game console the screen gets a warm tint and it causes the screen to display inaccurate colors at all, I would love to know how to solve this problem.
[Philips, Sony, TCL Android TV] tonarii:
Hi, I just thought about something, is it possible to change the tv resolution just like you can do when you use it as a PC monitor ? When you play old quality sources from regular tv channels for instance, to be able to just display the channel in native 1080p might be sometimes better than using the 4k upscaling function of the tv.

Do you think it's possible to do that ? And if not, why manufacturers don't let us do this ?
[Philips, Sony, TCL Android TV] lapist:
Yes, for some reason it gets warm/yellow colors by default. You can change color temperature to Normal or cold in advanced picture settings on the TV.
[Philips, Sony, TCL Android TV] pingpong100:
Wow, thank you very much, and I thought my TV was broken or something, I was very upset. Now that I have changed the color settings, will these settings be saved forever or will I have to adjust it, again and again, all the time?
[Philips, Sony, TCL Android TV] dexlemaffo:
once the color settings changed; they're saved
[Philips, Sony, TCL Android TV] stasiof:
You should take a time and read this threat.....

Has 4 main picture settings, all can be saved if is set to "Current input"...and not to...All inputs.
[Philips, Sony, TCL Android TV] pingpong100:
You are right, I will indeed do that, thank you very much!
[Philips, Sony, TCL Android TV] asikis:
Hello all. I recently bought a 55'' C635 TCL TV. Till now I am ok with this purchase. I am in SW version v477.

A few things i have noted:

1. First days of use, while watching TV channels, there was a time to time delay between sound and image. I shut down and turned on again and it got solved. I believe that this is a bug that hopefully will be fixed some time soon.....

2. In the Library section of the Google TV I cannot find any game to install. It is like any game title has been removed from the Google TV library for me. I search for "badland" or "crossy road" etc and i get feedback "something went wrong" or something similar. Has anyone experienced this issue before? Why I cannot see games section in the library at all? Or when searching for any game i get no results at all???

3. I have Apple TV+ subscription and watch some shows there. I can say that Dolby Vision is not impressive, at elast to my eyes. Looks like a filter to apply on top of the screen and that filter somehow removes some picture details. When i see a 4K video on YouTube without Dolby Vision, the picture clarity is much better. So is there a way to disable Dolby Vision from setting menu?

Thank you.
[Philips, Sony, TCL Android TV] lapist:
Which Xbox do you have? Can you try enabling VRR in Inputs settings and then in Xbox Video setting, to see if you can then enable Game Master function in the TV?
[Philips, Sony, TCL Android TV] lapist:
2. I tried installing Badland and it works fine for me - I installed it from Google Play store. Google Play is not visible as app in Google TV launcher, but you can open it from installed apps in Settings (or from a 3rd party launcher like FLauncher)

3. I have the TV just for a couple of days and didn't see much Dolby Vision content yet, but you can try installing firmware v501 (in IMG format) using USB stick as linked here (it will also make factory reset) - someone wrote here that it fixed Dolby Vision for him. To install the update, you need to place IMG file (extracted from ZIP) to root of FAT32 formatted USB stick, turn the TV off (e.g. by long press Power button on remote), insert the USB stick, and then start TV in flashing mode by holding Power button on TV (on bottom edge under TCL logo) for a few seconds until LED starts blinking...
[Philips, Sony, TCL Android TV] asikis:
Thank you for your answer @lapist . Much appreciated. I managed to install a couple of games by accessing Play Store from my pc browser and selected install the games directly to my TCL tv and it worked. I wil also check your proposal. The thing is that in C635 reviews in youtube, the library part has games shown. But my TV hasn't......Maybe with a next SW update this is fixed as well.

For the Dolby Vision, i do not believe i have an issue that needs a fix. It is more of personal taste of the picture seen. I do not want to setup everything from scratch, so for the time being i will not proceed with new SW installation via IMG unless it comes with OTA.
[Philips, Sony, TCL Android TV] lapist:
OK, in that case v496 here is the latest available for OTA via USB stick - it won't reset the TV settings, instructions. Otherwise I have no idea if Dolby Vision can be disabled somehow, I didn't see any options to do that.
[Philips, Sony, TCL Android TV] Wensum:
Proton's reply confirmed what you say. (VPN.ac also don't work when I looked more closely). Looks like it's back to firestick!
[Philips, Sony, TCL Android TV] asikis:
So you can actually play Xbox cloud games? Is the performance good? What game-pad have you used with? Xbox One controller works ok?
[Philips, Sony, TCL Android TV] Ed_Saxman:
Of course you need a GamePass Ultimate subscription to play cloud games, but yes!

The performance is simply amazing, if you have a good internet bandwith and a reasonably low lag. It's limited to 1080p, though, but is still great to be playing in a few seconds to hundreds of titles.

I'm using the original Xbox Series gamepad. It connects to the TV using Bluetooth. Probably not as good as using the 2,4Ghz mode (the gamepad supports both) in terms of input latency, but still good. Latency was neligible to me anyway.

All in all, I was VERY impressed with the GamePass app performance running in my modest TCL C635 TV. The Microsoft Cloud service is simply awesome. And I find the whole GamePass Ultimate service really CHEAP for what it offers: 13€/month and it covers my PC, my Xbox Series X, my iPad, my mac, my iPhone and even my TV, standalone!!

During 2022, the GamePass app has been an exclusive for Samsung TVs, with the exception of "manual" installs on our Android TVs. But the exclusive ends in a few weeks, so theoretically the GamePass app will be available for any other TV manufacturer.

Good times to be a gamer: you don't even need a console or a computer anymore!

Is it possible to control a Firestick 4k with the Tcl C635 remote?

I've added TCL in the TV Firestick device settings and turned on the HDMI-CEC on the Firestick and the TCL but no luck.
[Philips, Sony, TCL Android TV] hypnopt:
Hi, bought 55c635 recently, excelent value for money but I'm having lipsync/audio delay. If I reboot it it gets fixed buts it's annoying nonetheless, I even tried to disable fast start so it would reboot more often but sometimes I start the tv normally and it's delayed, then I reboot it and becomes ok. Can't really see a pattern here. Any clue how to fix? It's kinda a deal breaker if it's not possible to fix :( thank you.
[Philips, Sony, TCL Android TV] AsItLies:
I have same version, but not problem you indicate, knock wood. Mine is plugged in all the time, so powered but use remote pwr button to turn off.

One thing, I've never installed the google tv, just chose normal tv and use firestick exclusively.

Not sure that helps much, but I also use Avantree headphones wireless low latency. The sending device is connected with Aux, couldn't get the fiber connect to work, latency is okay even with aux.

what version firmware is on tv?
[Philips, Sony, TCL Android TV] hypnopt:
Hi, I'm only listening through tv speakers so nothing connected at all. Firmware version is v8-r51mt05-lf1v501 . I'm using Google tv, it's one of the reasons I wanted to buy this tv infact. Not sure if it's Google tv not helping though.
[Philips, Sony, TCL Android TV] dah145:
yes yo can, but it is awkward, you have to go to the cec menu in the TV, select firestick and go down to the menu option. You have to do this each time you want to control the firestick with your tv control.
[Philips, Sony, TCL Android TV] pingpong100:
I bought an Xbox Series X. I did activate the option of the games on the TV, after I changed the color settings on the TV, it worked out, thank you very much!
[Philips, Sony, TCL Android TV] Wensum:
Thanks for the info but I couldn't get it to work. I also read somewhere that there would be a conflict with the home button - ie when you press home on the Firestick it would go back to the Android TV home.
[Philips, Sony, TCL Android TV] pingpong100:
Hi, I would appreciate it if you could help me with something small - according to the specification of the television there is one connection of HDMI version 2.1, but this is not indicated on the television itself so I do not know which connection to connect the console to in order to get the performance of the better connection.
[Philips, Sony, TCL Android TV] aworan:
Hi,

I own a 43c635 Tcl Tv and it is very good for the price. I successfully flash the last update v501 image file, install flauncher and remove a lot of bloatware with adb commands. While I activate USB debugging from developer setting I saw there is and option to "Allow bootloader unlock" option. I turn it on, but what to do after ? I presume I must go to fastboot mode and do some kind of "fastboot oem unlock" command ? I try to reboot the tv via adb in fastboot / recovery and bootloader. But when I boot one of this modes I have just a picture on tv with "No command" written. I try to connect with an USB-A to USB-A cable from my computer to the Tv but command "fastboot devices" show no devices. Somebody successfully unlock the bootloader for c635 Tvs ? Or have some ideas of things to try ? It can be very good because the image v501 is an archive file and there is the boot.img inside so I can patch it with magisk, but I cannot flash it until I don't unlock the bootloader first. Thanks to share your ideas with me :)
[Philips, Sony, TCL Android TV] asikis:
I also have the same issue time to time and i fix it by rebooting the TV. I am on v477 Sw. But you are on 501, right? So it has not been fixed even in the latest SW. This is not a good sign....Maybe a hard reset could solve the issue?? Not sure what to suggest here.....
[Philips, Sony, TCL Android TV] lapist:
Right, I am curious about that too. Some specs say that the TV has 1xHDMI 2.1 and 2x HDMI 2.0, somewhere I saw it has 3x HDMI 2.1, but TV manual doesn't say which HDMI is what version, nor is it written on the outputs...I tested Xbox SS in HDMI1 and HDMI2 and didn't see any differences...

Discrete IR codes for C735

I am currently setting up a home control system to include a C735 98-inch model and looking for some IR discrete codes in HEX format.

Does anyone have them and is able to share?

Yeah i dunno I just turned tv on and it's fine. Sometimes it gets desynced and only reboot fixes it. I installed a couple of apps on Android tv dunno if that is not helping. I feel this processor isn't that great although I tried some streaming through moonlight and it performed decently.

Specifications of TCL 75C635. Display: 74.5 in, VA, Direct LED, 3840 x 2160 pixels, Viewing angles (H/V): 178 ° / 178 °, Static contrast: 6000 : 1, Refresh rate: 50 Hz / 60 Hz, TV tuner: Analog (NTSC/PAL/SECAM), DVB-T, DVB-T2, DVB-C, DVB-S, DVB-S2, CPU: ARM Cortex-A55, 1300 MHz, Cores: 4...

www.displayspecifications.com

it says just one hdmi 2.1 port. limited to 4:2:2. in reality its hdmi 2.0b spec. the regulations permit TCL to advertise as hdmi 2.1 because they have the VRR feature. but the bandwith is missing. the port indicated to have VRR is the eARC one also. so hdmi3 maybe. the features of the hdmi2.1 standard keep fluctuating. look up for a recent RTINGS YT channel on it. when i get 4:4:4 it wont be from TCL. even if its printed theres always gimmicks to deploy. i bought the TCL because i had only Samsung smart tvs so far. almost 10 units. i needed a CHANGE! i got the 75" C635 and absolutely NO DELAY but i never used Google TV! just the TV basic app for digital cable TCL has. plus many other sources outside cable. BT headphones work just fine. the main reason i am happy about the tv is the panel looks perfect. no bleeding blooming banding etc. wall mounted. bright enough for me.

i cant believe the 2.1 stuff is so weasel-ish but its not just TCL to blame. but for my budget i dont think i could have bought a better more complete overall product. but the 2.1 stuff was one i could have sworn this tv in 2022 has it covered. fully. at least 1 port...... no wonder it doesnt say on the back of the tv anything about 2.1.

Try to enable Apps Only mode in account settings, and limit background processed to 2-3 - that speeded up the TV GUI for me. I don't use TV tuner as I use IPTV apps instead, so I didn't notice the audio delay..
[Philips, Sony, TCL Android TV] lapist:
I figured it out, if somebody has the same issue - I enabled CEC on Xbox (+Xbox rebooted) and then Game Master works with VRR enabled.
[Philips, Sony, TCL Android TV] asikis:
I do not believe it is a CPU issue as the bug is not there when watching through Netflix, Apple TV, Disney+ etc. So it has to be a bug on the TV app (if we can call the normal TV viewing as an app....). Hopefully TCL is aware of the issue and will fix it in a future update.

And another thing: TCL shall provide change log with every new SW they release so that users know what has been fixed and if it worths updating their SW version.

[Philips, Sony, TCL Android TV] lapist:
I am not seeing this issue with Fire TV stick. You can try some things, like different HDMI port, changing some sound settings (like enabling/disabling Dolby Atmos etc), CEC, setting the output resolution and refresh rate on the TV box to match the content (e. g. 50 Hz instead of default 60 Hz), enabling/disabling Dolby HDMI pass through for audio on the TV box, or eventually contact TCL support.. The issue may be also on your TV box.
