At 300 Hz the monitor shows a new frame five times as often as a standard 60 Hz screen, which makes fast movement look sharper. FreeSync Premium and G-SYNC Compatible match the refresh rate to the frames from your graphics card, so the picture does not tear or stutter. Black eQualizer brightens dark areas, Virtual AIM Point puts a crosshair on screen and Super Arena Gaming UX gathers game settings in one menu.
The G40H suits competitive players who prefer a compact 25-inch screen where the whole view stays in sight. The stand raises by 105 mm, tilts and pivots to portrait, helping you find a comfortable position for long sessions. Flicker-free and Eye Saver Mode reduce eye strain. It weighs 3.8 kg with the stand and 2.5 kg without it.
