I was having problems with the Roku Express displaying the home screen menu settings fully. Each screen had the left side justified so far over, I could not read the entire menu option. Also, when I streamed YouTube TV, I could not see or access the top or sides menu selections. After a week of trying to change the display settings on the Roku, nothing helped. So, come to find out I discovered that I needed to change the aspect mode on my TV (Insignia) settings. It was set to cinema mode and I changed it to normal mode and that fixed the problem!
I hope this helps someone else who may be having the same issues.
