I already got it and unfortunately not all the games support this resolution. I have no clue how about league of legends but I had some problem with setting it up for starcraft 2. Apparently according to blizzard's official statement they will never support anything over 16:9 because it is considered as an advantage over other player with, lets say, more standard monitors and they want to keep all the online tournaments as much competitive as possible. So there is no support for ultra wide and multi monitors systems. Took me a while but finally I've found a proper tool to make it possible. Just downland flawless widescreen app and set it up for your monitor(s). They're constantly updated the database of supported games. The tricky part is that you might be banned in your game for doing so as some developers same as blizzard consider this as a kind of cheat. But the good new is that this fix doesn't modify game code, it simply modifies the resolution value in memory. You may give it a shot. Official website http://www.flawlesswidescreen.org/
