I have a 1366x768 resolution HD widescreen monitor .

I did xrandr -s 1366x768 and it comes out more neater, however I wanted something better.

You see, I use monitor shielding for emf/vlf/elf rays, that I bought from lessemf.com. It's not the size that completely fits my monitor and basically I want to change the light emitted to only be one large square section of the screen, the selective area where the glass covers the screen.



You know when you burn a dvd movie as playable on dvd using some dvd authoring program, it doesn't completely output to fit the tv screen, but there is like black rectangles on the sides. I don't know how to explain it well, sorry.

I just want to do this as a temporary solution until I get more emf protection delivered to me by next week.
