monitor will not show in full screen

hello,i have a toshiba e205 satillite and my monitor will not goto fullview when i'm watching video tutorials. There is a icon that has four arrows pointing in opposite directions(full screen) when i choose it the monitor goes black. These are art and digital art tutorials and i need to see them better. I think there is a power saving ajustment that needs to be changed. i looked everywhere for it and can not find it.

P.S. my toshiba service station is not working.

Please help
