I have had my Xbox Series S and TCL Roku TV(55S421) for over two years. Ever since I have had it, the colors of my games look cartoon-ish. Over the years I have toyed with the settings in order to fix it, but to no prevail. Today, I tried disabling the 4k/HDR on my Xbox and turned Game mode to "Off" in my Roku TV picture settings. I managed to turn Game Mode back to "On" and "reset to default" in my roku TV picture settings, but my Xbox will not let me re-enable 4K/HDR, because it says my TV doesn't support it.
I've tried a power reboot and went to power > restart on both devices. That did not solve the problem. Any suggestions?
EDIT: Nevermind, I figured it out.
