I discovered that my older 2017 TCL and new 2021 TCL TV’s can support 120 Hz at 1080P. This wasn’t advertised for either of these TV’s, so this may work on other TV brands as well. If you have a TCL TV that wasn’t advertised as a 120 Hz display, try the following.
That makes sense, though I still feel the difference when playing Ori and the Will of the Wisps at 120 Hz. There is an on the fly toggle in Ori’s settings that you can change back and forth. So while it’s not native support, I’d argue that the method I’ve provided is still a valid way of improving the responsiveness of games that support 120 Hz.
Using this method, the console believes that the TV is 120 Hz native, so from a system level, it allows the games to run at 120 FPS. While weren’t seeing 120 FPS, we can feel it because the game is running at double the speed.
Edit: This is only true of games supporting 120 FPS.
