Adaptive Sync:

Look for multiple connectivity options such as HDMI, DisplayPort, and USB ports. This ensures compatibility with various devices and accessories.


Features like tilt, swivel, pivot, and height adjustment allow you to customize the monitor's position for ergonomic comfort during long gaming sessions.
