Xbox One S 4k Issues with TCL 55S401 Roku TV

Hello everyone,

I bought the TCL Roku TV with 4K and HDR (55S401) about a year ago, and so far I am pretty impressed with how everything looks. I got an Xbox One S last night and was shocked to see that it's not detecting the TV as a 4K display.

Not only that, when I set the video settings on the Xbox to Auto-Detect, I get stuck in 640x480 resolution. I can only go to 1440p if I force it in HDMI mode instead of Auto-Detect. However there isn't an option to force 4K resolution. And on top of that, I tried putting on a Blu-ray DVD in the Xbox and it gave me the pink/purple screen HDCP error.

I set all my HDMI ports to HDMI 2.0 in the 'TV INPUT' menu, and I tried each port (1, 2, and 3) but that didn't work. I've also factory reset the TV twice and updated software to 8.2 build 6170.

I've also tried several different processes of power cycling and plugging in the HDMI cable in different orders with no effect. I am using the brand-new HDMI cable that came with the Xbox, and I tried another one that I had and it didn't work either.

I've called Roku support but they weren't able to help me. From what I read on other forums, I think it's a problem with the HDCP hand-shake or the EDID not being sent from the TV. If anyone else has had this problem please let me know. It's extremely frustrating to find out this awesome TV might be defective.

Any ideas what I should try?

Thanks.

I’m having similar problems specifically with the Xbox One S, I can usually force the resolution to work by switching HDMI modes from 2 to 1.4 and then restarting the Xbox but the next time I turn on the TV it’s broken again. Very frustrating

Re: Xbox One S 4k Issues with TCL 55S401 Roku TV

I am having a similar issue. When the xbox one s is hooked up to my TLC roku, the colors and visuals are extremely distorted, although everything else within the Roku seems to be working fine. I think Its an issue with the Roku because when I plug the Xbox into a different tv, it works like normal with none of the issues it has with the Roku.

Anyone have the same problem/have an idea to fix this?

Thanks for the post.

This may be related to a hardware issue. Have you tried contacting TCL support yet to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support for their products running the Roku OS. 
You can reach them here: https://support.tclusa.com/televisions or at 1-877-300-8837.


Thanks,
Danny
