FAQs

Does this monitor support wall mounting?

Yes, it features a standard 100 x 100 mm VESA mounting interface.

Can I use this for console gaming?

Yes, it supports HDMI 2.1, making it fully compatible with modern consoles like the PS5 and Xbox Series X.

Is there a risk of burn-in?

As with any OLED panel, there is a risk of image retention. LG includes built-in protection settings in the OSD menu to mitigate this risk; ensure these are enabled.

How do I split the screen into multiple windows?

You can use the 'LG Switch' application on your PC to manage display splitting and custom window layouts.

Does it include a built-in USB hub?

Yes, the monitor features both USB-A and USB-C downstream ports for connecting peripherals directly to the monitor.

What is the recommended viewing distance?

Due to the 800R curve, it is designed to be viewed from roughly 60cm to 100cm away for the most immersive experience.

Troubleshooting

Monitor fails to output 240Hz refresh rate

Ensure you are using the included DisplayPort 1.4 or HDMI 2.1 cable and that your GPU drivers are updated to the latest version.

Screen appears blurry or shows flickering

Check your OSD settings to ensure that 'Adaptive Sync' (G-SYNC/FreeSync) is correctly enabled and verify that the cable is securely seated.

USB-C power delivery is not charging the connected laptop

Confirm that your laptop supports USB Power Delivery (PD) and that you are using the provided high-speed USB-C cable capable of 65W transfer.

Pros and Cons

Pros

  • Incredible 0.03ms response time for fluid, crystal-clear motion
  • Expansive 21:9 aspect ratio provides an immersive gaming experience
  • Deep, realistic black levels thanks to OLED technology
  • 65W USB-C power delivery allows for single-cable laptop setups
  • High-end gaming features like G-SYNC and FreeSync Premium Pro compatibility

Cons

  • Very large size requires a deep and wide desk configuration
  • OLED panel requires maintenance settings to avoid burn-in
  • Higher power consumption compared to smaller LED monitors
  • Premium pricing reflects the high-performance panel technology

Setup, Compatibility & Care

To begin, mount the display using the included L-stand or a compatible 100x100mm VESA arm. Ensure your desk is at least 60cm deep to accommodate the monitor's curvature and footprint. Use the `DisplayPort 1.4` cable for maximum bandwidth on PCs, or `HDMI 2.1` for console gaming.

For care, it is vital to enable the built-in OLED protection features via the On-Screen Display (OSD) settings. Avoid leaving static images, such as taskbars or browser logos, on the screen for extended hours. When cleaning, use only a soft, dry microfibre cloth; do not spray liquid cleaners directly onto the OLED panel, as this can damage the sensitive coating.
