Sorry, there was a problem. Please try again later.If it's not filling the whole side of the screen and you have the PBP mode set to 1/2-1/2 16:9 dual input (instead of the 1/3-2/3 or 2/3-1/3 mode or the triple input 1/3-1/3-1/3 mode) then one or both of your laptops is probably not set up to run a proper 16:9 (and 1920x1080) resolution (and isn't set at 60hz or less) as needed for proper PBP mode operation.
