When you connect a game console such as PlayStation or Xbox to your LG TV, you can enable Game Optimizer (or Instant Game Response on some models) to reduce input lag and apply game-focused picture settings.
This issue can occur if the connected HDMI port is not configured for enhanced HDMI signal (HDMI Ultra HD Deep Color/HDMI Deep Color), if the TV is using a different menu structure based on webOS version, or if the TV is not currently using the HDMI input where the console is connected.
If HDMI Ultra HD Deep Color (HDMI Deep Color) is Off for the port your console uses, Game Optimizer-related options may be limited or unavailable.
Depending on your model year, you may see Game Optimizer (webOS 6.0 and later on many models) or Instant Game Response (common on webOS 5.0).
Some settings are easiest to find and apply when the TV is switched to the HDMI input where the console is connected.
Setting: Settings > General > Game Optimizer
1) Turn on the TV and switch to the HDMI input where your game console is connected.
2) Press the Settings button on the remote.
3) Select All Settings.
4) Open General, then select Game Optimizer.
5) Set Game Optimizer to On.
