note: I have 2023 LG G3, so it's a bit different than previous models

press green button (magic remote) 7 times to access VRR Information screen, shows refresh rate, state, resolution and color depth

press mute button 3 times shows another menu, that lets you change some settings, like logo display, and auto power sync, and if wallpaper is displayed when no signal.. av reset, a number of things

settings>>general>>channels.channel tuning will be highlighted, press "1" 5 times and you get a host diagnostics information panel, lots of info

 long press 0, lets you edit the quick access menu, you can have long press on a number key access an app

more actions menu, with arrow on screen (shake remote if no arrow) press scroll wheel, some more settings, including changing the banner location

For the "secret" menu, the access method has changed...

Use the factory service remote, and use the "P-only" button, before the "In start" button worked, but now it only gives some limited information and little to change

• press ""P-only" button
• enter 0 4 1 3 into the 4 circles
• the tv will now reboot
• when you see the box with "Power Only", now press the EXIT button, and then the "IN START" button

You should now have the "original" secret menu, using the up and down keys you can scroll through the 19 menu items

 in the OLED menu, people often turn of TPC and

GSR - Global Sticking Reduction

TPC - Temporal Peak luminance Control -

ASBL - auto static brightness limiter (system 1 menu)

adj key will now take you to more settings

 to exit press menu  button, WAIT 30 seconds, and then press the HOME key on the original magic remote

 after all of this, pressing the IN START button will take you to the menu without using the password... use exit to exit
