Not sure what your monitor size is ?
Monitor Size: Unknown
Iphone 4 2
Htc hero 2
Genius m712 tablet
Ipod touch 4g black
just a teeny tiny bit too long like 4mm on a 17"
Perfect on a 19'' screen
i think mines bigger :P (i cba to go get it)
I checked it with my nano 3rd gen. It's pretty much exact. :-)
