There's lots to know if you're choosing a new gaming screen. All the major companies bumped their flagship 1080p configurations to 360Hz, but for many a gamer, they're not essential: 240Hz max should be fine for those few times you can get frame rates above 240fps. Even 144Hz will do for many people. But artifacts like tearing, caused by the screen refresh rate becoming out of sync with the frame rate, depend on your games as much as your laptop brand and hardware. We're also seeing a lot more 120Hz 4K screens in the flagship models in all sizes and a ton of 165Hz and 240Hz QHD (1440p) options. The latter are my favorites, balancing higher resolution -- certainly enough on a laptop screen -- with gaming-friendly refresh rates.
