AOC are showing off their two new 34 inch curved 21:9 gaming monitors, the CU34G2 and CU34G2X. The former smashes out a 3440x1440 resolution and matches it with a 100Hz refresh rate and 1ms response time.
The CU34G2X still hits the same resolution but bumps up the refresh rate to 144Hz. It also still maintains the 1ms response time.
Both monitors support AMD FreeSync to maintain smooth gameplay, they can't improve your skills but give you all they can to help.
