1440p is quite demanding when it comes to the latest games. Luckily,
AMD FreeSync will provide you with a variable refresh rate (VRR) which eliminates all screen tearing and stuttering within the 48-144Hz/FPS range (LFC supported) by synchronizing the monitor’s refresh rate with the frame rate of your GPU at minimal input lag penalty (~1ms).
The LG 27GL850 144Hz gaming monitor is certified by NVIDIA as G-SYNC compatible, so you’ll be able to take full advantage of VRR even if you have a graphics card by NVIDIA (requires a GTX 10-series GPU or newer). Note that the LG 27GL850 FreeSync range is limited to 48-100Hz over HDMI.
