A Note About Resolution
HDMI 2.0 is limited to 3440x1440p @ 100Hz refresh rate or 2560x1080p @ 120Hz refresh rate.
For max. resolution/refresh rate, using the DisplayPort 1.4 is required.

Level-up with the Viotek Gaming Suite that includes GAMEPLUS crosshairs to enhance your aim, turning every shot into a bullseye. Spot enemy targets in shadow-heavy games before they get the drop on you when you activate FPS/RTS display modes, which brings out extra detail in darker images. Turn on MPRT anti-ghosting mode* to boost speeds and decrease input lag for even faster responses times. Use the adjustable blue-light filter to reduce the harmful effects of blue light exposure and minimize eyestrain. After all, with all this winning, you’ll want to play all night. V4Victory!

* MPRT Mode is incompatible with Adaptive Sync.
