On the FireTV version, while on the desired input: Press the “Gear” button on remote (top right below power button) Select “Picture” option. Scroll to the very bottom and select “Advanced Settings” Scroll to the very bottom and select “HDMI Input Mode” Change setting to “Mode 2 (2.0)” Hope this helps.
Thanks for the reply. Unfortunately no luck. AppleTV 4k recognized the S551F as 4k HDR10+/DV compatible, but the FireTV OS crashed persistently. This was with a HDMI 2.1 cable and enabling 2.0 speeds on the TV. A massive flaw, as this TV is advertised as capable of HDR10+ and DV. Have returned and switched to a Hisense U7. Wow. Google TV OS is light years better, and the Hisense just looks better. If you’re considering buying this TV for a dorm room, it’s a good deal, but if you’d like to utilize those features like HDR10+ / DV, this is not the one.
Yeah that’s right, if your external player is doing the upscaling for you then you won’t have to worry about this. If you do plan on using an older device like a Wii, there are also external upscalers available that will do a much better job than the TV’s built-in processing.
Thanks for the reply Adam, sounds good! :)
Can you explain how to do this? S551F, and anytime I try to play HDR or Dolby Vision content via AppleTV, it seems the FireTV OS just crashes. I imagine being locked to HDMI 1.4 would explain it, but I see no options regarding changing this.

So, I was considering this just as an extra, basic TV for an extra bedroom. Just looking for something cheap, so this would be fine enough. My main concern would just be the upscaling. My understanding is that this is actually referring to upscaling when the TV is doing it itself, correct? So if I hook up a DVD player or a Wii or something to the TV, it wouldn’t look great, but let’s say I hook up a newly released Switch 2, and play some 900p Switch games on it that the Console itself is upscaling to 4K. In that case, the Console is doing the upscaling, so it would be fine, right? If that’s the case, it’s not much of a worry, but otherwise could be a dealbreaker.

For anyone trying to use this screen as a monitor, it will not output 4:4:4 chroma @60hz by default in PC mode, it is locked in 30hz 4:4:4 chroma or 60hz 4:2:0 chroma due to limiting itself to HDMI 1.4 under its auto-detection. You need to go into the settings and change the HDMI mode manually to HDMI 2.0. This is true for the S551F (FireTV), S551G (AndroidTV), and S555 (Roku) versions of this set. This may only be an issue with Nvidia GPUs but not confirmed. @rtings please update the inputs and PC Monitor section to reflect this necessity.

Can these TCL “Roku” and “Google TV” smart TV’s be used WITHOUT connecting TV to internet? I JUST want the TV, gaming and streaming from an external USB stick
Yes! Google TV also offers a basic mode that completely disables all connected features like this, so you don’t even have to worry about the TV nagging you to connect to the internet or create an account.
