Hello, I'm considering buying a C935 and wanted to know if it's worth it or if I shouldn't. I once had a C825 and it had a lot of bugs. Does the C935 have as many bugs as the C825?

Hi guys, Iam looking for help with my new 65 c735 and connection to PC. It has been really flustrating few days I spent with the PC to TV connection.
I have 3060ti card capable of 2.1 as well as a 2.1. cable (unfortunately 10m long because of the room spacing. its a special cable with internal electronics - tried 2 different cables already).

My problem is that when I send signal from PC to TV in 4k 120 Hz to port 1 in tv (144hz capable) I cannot activate VRR because I loose the signal.
If I activate VRR in tv settings the TV goes immediately to no signal mode. When I deactivate VRR in settings the TV goes back to normal PC signal and I see the picture from PC.
also the game bar doesnt allow me to go rapid-two thunders (black screen/no signal), only normal and eco seems to work.

without rapid screen settings I also dont see G-Sync tab in nvidia so I cannot activate that too. On normal or eco mode I cant see the G-Sync tab in nvidia settings.

Tried several settings in windows and nvidia panel but no luck so far.

any ideas what to do?

I think 10 meters are too long for the HDMI cable even with special electronics. Try an optical HDMI cable.

Yep, tommorow I will try to move the PC closer to the TV and try to use shorter 2.1 hdmi cable for a test.
To my knowledge this 10m cable should be working too... Its a special optical fibre cable that specificaly supports VRR among other things.
I have a bad feeling that the new and shorter cable wont make a difference for me but I will test it anyway to confirm the cable compatibility, I suspect Iam having something wrong in the settings in either TV or PC.

didn't know you were already using an fiber optic cable. maybe it's because the C735 doesn't support Nvidia G-Sync.

Copy apps on USB ,insert USB in TV input and install.
Thanks for your prompt reply, but I had already tried to install the files and pretty much thought that I had exhausted all possibilities. However I input the USB drive, from cold or warm start, or through the TV apps the USB is only recognized as a media device and shows media files only!
Do I need an app to see .apk extensions?

It seems like it's fixing most of its minor bugs, but it has 2 major faults that it doesn't seem to be fixing or maybe not able to fix. One is unusable crackling sound with Dolby sound in cinema sound setting in the build in speakers. The other I guess is only a problem on the 75 inch with bright line and with certain colors really distorted coming far down below the black bar when for example watching movie with the right aspect ratio. It's actually also to the right of black content but that's minimum how much that ruins things. But for me, the top distortion is completely unacceptable. It can be helped with local dimming on low or disabled or turn contrast way down, but that's not acceptable solutions.

They do recommend 2m cables or less for optimum bandwidth, however i have the same GPU and the same TV and can tell you that its better to run one HDMI from the GPU to port 1 on the TV, and then i have a second HDMI (extended display) running from the onboard Intel graphics to my AVR which does audio. This way seems to be better but i am yet to be able to activate G-Sync. The VRR is only supposed to work with game consoles i think.

You need to go to system menu, about, update. And choose local install (usb) and it should work.

I had also a similar problem with output resolutions , refresh rates and color output with my 55C835 paired with the amd rx 6900 xt. If it's not the gsync incompatibility or the cable length maybe you should look the bandwidth your nvidia rtx 3060 ti can give, look specs from other sites about the resolution, refresh rate and color output it can deliver.

No VRR also works with PCs. I have activated it at my pc. At PCs VRR is also shown as GSync by nvidia or FreeSync by amd.

    No one test the beta version..
    This is a forum for people who do exactly that. Developing and testing different firmwares and other forms of software development. If people didn't do that then you wouldn't have a forum to whinge on. Everybody is different and everybody has different things they enjoy doing, so I'd say yes there is people that care about it despite the fact that you may not.

    I have 50c735 europe_pl (bought and use here) first set up update firmware to v477, but that's it, no more updates to do, it says - nothing to update. I know that there are few next updates so I decided to do update by myself, but to be sure and safe, just for know I just update with v496 OTA, of course reset shop, reset all and after that full factory reset and configuration of all Google TV once again with all apps etc.. Hmm.. I don't know if this update give something new, may be some functions or naming of it, may be little smooth feeling, but rather little not many. Hmm, but what I noticed, after update the screen is more more red.. and maybe pink moreover in some movies/ apps so I have to change white balance in expert mode 2 points and red boost set to -16 and blue -2, now is very good, but.. hmm someone also noticed it?? Some said here that the Dolby Vision is repaired now, but don't know what, maybe is more smooth, maybe - ok, but still the problem about @OnyOnaki said above actually exist. I can't say that is brightness lag, its like a delay in led backlight software saying about reaction. Hmm Im good with that to be honest, it doesn't annoying me, but some in my family said that is really not cool. Hm.. in my opinion this is a dynamic hdr so..., but yeahh.. it could be faster... To avoid big jumps of brightness I set bright preset and gamma -1, everythings OFF and dynamic mapping on OFF [but to be honest this option is really good to have ON, because of details that he helps you to see in very white scene, but.. also makes more work to brightness regulators]...

    I think about v501 flash via IMG and make completly fresh instalation, but.. don't know if it make sense. I think the main problem is CPU and everything we say its about him. TCL make not good move with making money on us who don't need big-bigg screens and they implement ****ty realtek CPU inner <50 inchs. Really sad, because these TV to be honest isn't the cheapest we can buy, but maybe some updates helps us.

    Maybe someone has calibration settings for these C735 SERIES to 50 inches etc.. screens, I mean of course calibrated with sensor, not on eye, because on eye I also did that, I've got good eye hehe, but if someone has settings made by pro, it will be be nice to share with us.

    Someone test v501 on c735? I saw there isn't at v501 OTA so.. I don't know if it is safe.. and if it is worth to update.


    EDIT: UPDATE ABOUT FOR ALL OF US WHO HAVE DOLBY VISION BRIGHTNESS PROBLEM, THERE IS A WORKAROUND SOLUTION AND SOMETHING LIKE A GOOD NEWS.

    I found these instruction here on xda in other thread with beyond TVs:
    1. Activate Quick Start (EVEN if you have this option ON, just do TURN OFF AND TURN ON THIS OPTION once AGAIN)
    2. Turn off (hold power button on remote control 5 seconds and say YES/ OK to turn off question and unplug the TV and of course after 10-15 sec, plug in powercord to TV again)
    3. Turn on the TV
    4. Let it load all the GTV UI
    5. Turn off the TV with the remote control button (but not completly, just one short click - to quick start standby mode)
    6. Turn the TV back ON with the button on the remote
    7. Put the movie or series with Dolby Vision
    8. Enjoy, finally, the movie or series without brightness changes in the scenes

    And if you always use stand-by quick start turn off turn on method od remote control, these will be work. If you unplug TV or you lost power on TV powercord you will need to do that ALWAYS ONCE AGAIN AND AGAIN [DON'T SKIP ANY STEP, JUST DO THAT ALWAYS THE SAME WAY]. Don't test it how it will be working after few days and making a mess with apps etc.

    And these is that good news - its only firmware problem, not a hardware, but the question is if the TCL knows about that and has a will to repair that in next updates. Some say here that the V501 repair that. Don't know, im on v496 now after manual OTA update with V477 stock firmware, but on these two version, it was the same problem. Maybe I will try to V501 IMG full firmware flash with reset all and reset shop before, and factory reset after flash this IMG and I will also report if that helps or not, but to be honest I think TCL don't know how to repair that. I know one TV from my country which is on the market warranty Service and 7 days after still we don't know what will be done in this case. I also forward these news and instruction how to workaround these problem and maybe service will contact with TCL SUPPORT and MAYBE THEY forward this information on the next steps, but to be honest in these budget - the only we can do now is to have hope that they will still work on these platform, it's 2022y model so maybe... Don't know, will see.
