see what you need to do is go down to the beach and get yourself some sand
hook the 360 up to the monitor and power on both the monitor and the 360
open the disc tray of the 360 and pour in two tablespoons of sand whilst whistling the theme tune to the a team
next, take a piece of A4 paper and coat it in a layer of glue, pour the rest of the sand over the glue covered paper so it sticks to the glue, you now have a sheet of sandpaper
rub this sandpaper over the monitor screen and wait for 5 seconds
the 360 should now reset automatically and when it turns back on it will be displayed on your monitor
hope this helps
