There's also factors like input lag that are separate from display refresh that can be a problem for people playing action games. Even casual players can notice some high input delay from time to time (we're into the 100ms+ range) so it's a good idea to check the display's input lag if games are anywhere near a possibility. While I like my 34UM95P for professional purposes it's really not that great for games that are much more than interactive movies. In contrast, nothing stops me from using an Acer x34 monitor for coding 95% of the time.
