Q: Why would different devices cause issues even on the same TV?
Every device manufacturer implements HDMI specifications differently so that incompatibilities can arise. Factors like the processor, graphics card/chip, onboard memory, and installed version of the operating system contribute to each device's unique HDMI personality. Updating systems helps bridge compatibility gaps between brands as standards evolve.
Q: What if resetting to factory defaults wipes out other settings?
Backing up is highly recommended before taking that step. Most modern LG TVs let you save presets like WiFi passwords, customized app positions, and input labels to an external storage device in Settings. That way, your customizations can be restored quickly after a reset. It prevents unnecessary headaches.
Q: Can using a different HDMI port on my A/V receiver help?
It's possible since some receivers have HDMI inputs that support higher bandwidths than others. By trying alternate ones, you effectively change the cable between your source and LG TV to see if it helps. Be sure any inputs involved support the resolution you need, like those labeled for 4K/HDR.
Q: Can adjusting display settings on my PC help?
Yes, manipulating your PC's resolution settings is worthwhile. Right-click the Windows desktop and then select Display Settings to check your current output resolution against your LG TV's specification. Ensure it matches, or temporarily lower it to a more basic option to test compatibility.
