Frequently Asked Questions - OLED77G45LW LG
How do I clean the OLED screen?
Use a soft, dry microfiber cloth to gently wipe the screen. Do not apply pressure or use any liquids, as moisture can damage the panel. For stubborn smudges, slightly dampen the cloth with distilled water and wring out thoroughly before wiping.
Can I mount the OLED77G45LW on the wall?
Yes, the TV is VESA compatible (300x300 mm). Use a professional wall mount designed for the weight and size. Ensure the wall can support the load and cables are properly routed. Refer to the manual for specific screw lengths.
Why is the screen not turning on?
First, check that the power cord is securely connected and the outlet is working. Try pressing the power button on the TV (not just remote). If still off, unplug for 60 seconds and plug back in. If problem persists, the power supply board may need servicing.
How do I connect external devices like a soundbar or game console?
Use the HDMI 2.1 ports (labeled with eARC for soundbar) for best performance. For game consoles, enable ALLM (Auto Low Latency Mode) and VRR in the TV settings under 'Game Optimizer'. For audio, you can also use optical out or Bluetooth.
How do I perform a software update?
Go to Settings > Support > Software Update and select 'Check for Updates'. Make sure the TV is connected to the internet. You can also update via USB by downloading the update file from LG's support site and following the manual instructions.
What do I do if the remote control stops working?
First, replace the AAA batteries. If still not working, re-pair the remote by pressing the OK and Back buttons simultaneously for 5 seconds (magic remote). Alternatively, use the LG ThinQ app as a temporary remote.
Is there burn-in risk with OLED?
Modern LG OLEDs have built-in features like Pixel Refresher and Logo Luminance Adjustment to minimize burn-in. Avoid displaying static images for long periods at high brightness. The Screen Saver activates automatically when no signal is detected.
How do I enable Dolby Atmos?
Dolby Atmos is automatically enabled when playing Atmos content via HDMI eARC or internal apps. Ensure your soundbar or AV receiver supports Atmos and is connected to the eARC port (HDMI 2). In settings, set Digital Sound Out to 'Auto' or 'Pass Through'.
What are the warranty terms?
Typically, LG provides a 2-year warranty covering manufacturing defects. Panel warranty may be longer (up to 5 years) in some regions. Check your region-specific warranty card or contact LG support for exact terms. Keep your purchase receipt.
How do I enable accessibility features?
Go to Settings > Accessibility. Options include Audio Description, Closed Captions, High Contrast, and TalkBack (screen reader). You can also assign accessibility shortcuts to the remote's number keys.
