Make the call to LG and if they can't correct it, return it. Shop for HDR in your next set.
Hi. I have a 4K LG TV.
When the picture is on high resolution I get one or two small shadowy boxes on the screen. The are about 5in x 3in. If I turn off TV they will go but soon one or both will soon reappear. Any suggestions how I can sort please as quite annoying .
