So my laptop monitor is 1366*768 and my TV is 1920*1080. When I use the laptop screen alone, the wallpaper is stretched to the size of the laptop screen, but when I hook up the TV monitor and use the "Extend These Displays" function, the wallpaper on the TV is the same size as it is on the laptop (ie. it doesn't fill out the screen), but all of the black space around the wallpaper is still usable.
How can I make it so that the wallpaper fills out both the laptop and TV screens with the Extended Display mode?
Okay, I might be wrong then. The monitor is probably 1920x1200, but the thing is is that the display area is the correct size so that I can utilize the entire monitor. The issue is that the background image does not stretch to that size as well; it just stays the same size as it is on the laptop monitor.
It isn't a really big issue, but I know that we'd done it before at work with two monitors of different resolutions,
