My display has always been full screen coverage then suddenly yesterday I turned it on and I have what I assume is a 4:3 ratio instead of using the whole screen. I restarted the roku stick (3600x) both through the software and by unplugging but no change. I tried switching from auto to 720p to 1080p and all screens still not filling whole TV. I don't know what else to try. Suggestions? Thanks for your help.
Thanks Dan. I did some searching on my TV and was able to correct it. Not sure how it could have happened accidentally, it took a number of button pushes to fix it! I originally looked at TV but only things that could be changed with a single button push thinking the same thing. Thank you very much! Was tired of squinting at TV, lol
