Have TV Questions? Ask a TV Technician
Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
Do you have any issues with using the LG with another (non computer) device, such as a cable box, dvd player, etc?
Thanks for confirming.
That isn't surprising to see, this tv is not really designed for use as a monitor, and doesn't officially support a pc.
That said, the issue is going to come down to a graphics card setting or incompatibility on your computer.
Go into the resolution settings on the pc, and set it at 1920x1080 or 1024x768.
If no change, look in the advanced graphics settings for a scan rate (hz) settings, and try a few different options there: 60, 59, 57, etc until you find one that fits.
Thanks, ***** ***** know if you get stuck and I'll advise further.
