The TCL Q550F is an okay TV for mixed usage. The TV's contrast is decent, but its HDR brightness is just alright, so it's not very good for dark room usage or for watching HDR content as bright highlights don't really pop, and blacks are raised whenever bright highlights are on screen. On the other hand, its SDR brightness is quite decent, and it has good reflection handling, so it's a solid pick for watching SDR content in a moderately lit room. Unfortunately, the TV has a narrow viewing angle, so it's not a good choice to use in a group setting. The smaller sizes of the TV are barebones when it comes to gaming features, although it does have VRR. Sizes bigger than 50 inches have some modern gaming features like 1080p/1440p @ 120Hz, with a wider VRR range.
