Changing Screen Resolution with Blank Screen

I am having an issue where my Roku logo will appear flashing on my screen maybe 5-7 times and then the screen will go pixely for .5 seconds and the screen goes dark.

I believe that I need to change my screen resolution, but do not know how to do this when the screen is blank. Any guidance on what button sequence to press on remote?
