DIAGNOSIS The infrared (IR) receiver on the monitor is likely being blocked or you're dealing with low batteries or IR interference. The sensor is behind the bottom bezel, centered.
FIX Start with the remote itself and your positioning.
- Replace the remote's batteries (CR2025). Weak batteries reduce IR signal strength dramatically.
- Ensure you're pointing the remote at the center-bottom of the monitor's front bezel, not at the screen. Stand within 15 feet and at a reasonable angle (not extreme side angles).
- Remove any obvious obstructions in front of the monitor's lower edge, like a soundbar, webcam, or thick monitor riser.
- Check for strong sources of infrared light, like direct sunlight or incandescent bulbs, shining on the monitor's sensor, which can flood it.
IF THAT DIDN'T WORK Test if the remote works flawlessly from very close range (2 feet). If it does, the remote is fine and the monitor's IR receiver might be faulty. If it's still inconsistent, the remote is defective.
HEADS UP The remote is primarily for the volume rocker, input switching, and HDR toggling. For most other settings, using the physical joystick on the back of the monitor (downward for menu) is faster and more reliable.
