I have a 47" LG TV after doing a factory reset the picture is too big for the screen, have tried aspect ratio from TV remote with no change
Thanks for the post.
Does the issue only occur on a specific channel or all channels installed on your Roku device? Could you reply here with a photo of the problem you're experiencing? We'll be able to further assist you from there.
We look forward to your response.
All the best,Kariza
