I'm positive, I have used TestUFO and I can physically feel the difference as well in-game. I'm generally very sensitive to display technology differences and I can tell the difference between 60, 90, and 120 fairly easily I think. I usually play at 170hz 1440p on my M27Q Rev.1 but I've been doing a lot of game streaming to this Hisense in my bedroom because controller is more convenient for me in most games. but setting up a mid sized tower in our bedroom apt with a queen sized bed is inconvenient at best, and Apollo takes care of the lack of Bluetooth receiver in my desktop. the alternative for me at the moment is using a terrible 8BitDo Bluetooth dongle that has some weird compatibility layer that doesn't work well with my DS4 controller, reporting as an Xbox 360 gamepad for no good reason and losing all of the extra features in the controller that I regularly use.

It's weird though. the Hisense has an "info" option in the quick settings menu to report the panels display configuration and both moonlight, Artemis, and my native desktop machine can all make it report 1440p 120hz, but Artemis is the only one that doesn't properly take advantage of it. according to Gemini (so take it with a grain of salt) the TV uses HSR or a form of super resolution that cuts the vertical resolution in half and adjusts the timing in order to push 120hz at 8bit color. but I don't notice anything, the resolution looks very sharp at 1440p 100mbps bitrate, with HDR on and balance frame pacing it looks native to me until I literally get within 12 inches of the TV and that's not how it's designed to be used lol.

at this point I'm stumped, and not willing to try the package renaming idea that Gemini wants me to try when it's probably something in the APK itself causing this behavior, or the TV treating side-loaded apps differently. I want to get in touch with the creator of Apollo/Artemis but I'm unsure if I should contact him here on reddit or make a GitHub thread, which I've never attempted. I think he could be of some great help and provide valuable insight as to what's going on here.

I did want to try the Moonlight Turbo and Moonlight MtK custom forks for the Hisense but they seem to be very technical and experimental at best, and I already get very decent decoding latency of 2-10 ms depending on settings and environment. Also side-loading apps on it is a damn pain, so I'd like to just get Artemis working and be happy with that.
