How Do I Connect a PC or Console?

Turn both devices on and select the input you used through the joystick shortcut or menu. For a first test or a missing picture, use 1920 x 1080 @ 60Hz and add adapters or docks only after the direct connection works.
How Do I Choose the Right Resolution and Refresh Rate?
| Connection | Supported modes |
|---|---|
| HDMI 2.0 |
3840 x 2160 @ 60Hz or 1920 x 1080 @ 120Hz
|
| DP 1.4 |
3840 x 2160 @ 72Hz or 1920 x 1080 @ 144Hz

Select the M27U6 in your PC's display settings, set the intended resolution first, and then choose an available refresh rate. Use 4K for sharper text and images; choose 1080p when a higher refresh rate matters more. If a mode is missing, confirm the selected input, source output, cable, and display settings. Return to 60Hz if the screen becomes unstable.
How Do I Adjust the Picture?
Use the rear joystick to open the on-screen menu. Move up for input, down for brightness, left for gaming assistance or return, and right for a preset or selection. Press briefly to power on or open the menu; hold for about three seconds to power off. Adjust brightness and the picture preset to suit your room. If HDR content looks wrong, check the source device's HDR setting and the monitor's picture mode.
How Do I Clean and Care for the M27U6?
Turn it off and unplug the power cord before cleaning. Wipe the screen gently with a soft, slightly damp cloth. Avoid liquid spray, hard objects, pressure on the panel, and blocked vents. Keep it away from heat and humidity.
Troubleshooting M27U6 Problems
The monitor has no power or picture
Check the outlet and power connection. If the power indicator is on, open the menu, choose the connected input, and reconnect one direct video cable. Test 1920 x 1080 @ 60Hz before selecting a higher mode.
4K 72Hz or 1080p 144Hz is unavailable
Use a DP 1.4 connection and a suitable cable for these modes, then check that the PC supports the selected resolution and refresh rate. HDMI supports lower maximum rates at these resolutions.
The picture is dark, blurry, or flickering
For blur, select the intended native 3840 x 2160 mode and adjust operating-system scaling for text size. For darkness, review brightness, picture preset, and the source's HDR setting. For flicker, return to 60Hz and compare another cable or input.
Frequently Asked Questions
Can the M27U6 run 4K at 144Hz?
No. The M27U6 supports up to 4K at 72Hz through DP, or 1080p at 144Hz through DP. Choose the resolution and refresh rate that fit your task.
Why is 144Hz missing when I select 4K?
The 144Hz mode uses 1920 x 1080. Select 1080p to make that refresh rate available.
Does the source device determine available modes?
Yes. The monitor, selected input, cable, source output, and operating system must all support the mode. Test one direct DP connection if a dock or adapter offers fewer choices.
