[LG TV Screen] Colors bleed

Color bleeding may be observed in certain broadcasting channels due to poor reception of broadcast signals.
If you experience symptoms like color bleeding and color overlap, particularly on a specific channel,
it is advisable to contact your set-top service provider for further assistance with the signal check (cable TV, Skylife, IPTV, etc.).

Causes and Symptoms

• The broadcast signal strength is weak.
• The HDMI cable connection between the TV and the set-top box may not be in good condition.
• Ultra Deep Color is disabled.

When using a set-top box, an incorrect Ultra HD Deep Color setting can result in various symptoms, such as color bleeding and abnormal colors.
If your set-top box (including the HDMI connector) supports a picture quality of 4K (3840*2160), set it On.
If your set-top box supports the HD (1920*1080) or lower picture quality, set it Off.
