any recommendations to adjust settings to have it fit correctly? if I adjust the resolution to a lower setting it tells me that its not the optimal resolution.
I have same issue with my compute stick as well as a NUC.
Issue seems to be that my TV assumes overscan. I guess this is an HDMI handshake issue with the Intel bios/drivers. To work-around I go into the Intel HD Graphics Control Panel - Display - General Settings - Custom Aspect Ratio and move the scroll bars to 85%.
I had the same problem on my LG 60" plasma HDTV. In my case, I used the remote for the TV to set the screen into "Justify" mode, rather than let the TV try to figure out how to scale the resolution set by the Stick.
That worked just fine. Now my Stick displays 1920x1080 perfectly sized for my TV screen.
If your TV has controls to set the aspect ratio of the TV, you might find a similar function for you to use.
