The owner's manual for the LG 75” Class UT75 Series LED 4K UHD Smart webOS TV (2024), Model # 75UT7590PUA advises to use a certified cable with the HDMI logo attached. If you do not use a certified HDMI cable, the screen may not display, or a connection error may occur. The recommended HDMI cable type is the Ultra High Speed HDMI®/™ cable (3 m (9.84 feet) or less). That is the recommended HDMI cable for 4K or 8K TVs regardless of brand or manufacturer...^Ivan.
Sorry, there was a problem. Please try again later.
