video size not showing info on right side screen

I have a problem installing a file by zip. I go through all the steps until after approx 10 steps where I click the jarvis (16.1) and there it stops. My screen does not show an ok to click on and does not install. Tried going to home screen/display and increasing and decreasing with arrow buttons but sideways doesn’t seem to change. cheap remote w/o keyboard doesn’t seem to move it left or right
