Resolution Question

I have tried both 1080 and 750 in settings but my picture continues to be square instead of oblong and filling the screen. Does anyone know how to fix it?

Re: Resolution Question

Is it specific, or all content?  Does the menu also appear in a box instead of full screen?  What Roku unit do you have and how is it connected to the TV?

Re: Resolution Question

This may be a setting on your tv, not the Roku.

Do you have one for "picture size" or something similar? For a wide screen tv, be sure it's not set to 4:3.
