Display Resolution

I have Lakka installed on an old laptop. I have tried both HDMI and VGA out of the laptop to the TV. In both cases my TV sets to 1080p and the Lakka OS only outputs 2/3ish of the screen. Is there a way to set the resolution in Lakka?

Thanks for any help.

If you go to settings > video, you can turn off integer scaling, which will make it take up the full vertical resolution and you can set the aspect ratio to 16:9 if you want it to stretch to the full horizontal resolution.
