completely agree with you
Since the size of the monitor is pretty much between 14 to 17 you wont see a difference between 720p and 1080p.The difference is evident only if you have a 42inch Plasma/LCD
however i have not been able to differentiate betweem 720p and 1080p on my 40" bravia. While playing games on my PS3 some games play on 1080 while most do on 720. Till date i cant say which ones which.
