Crt 4:3 to a 16:9

Question

this may sound stupid but i'll give a reason after i ask you this, can i adjust a 4:3 crt monitor height and stuff, to a smaller 16:9, the thing is i have 2 hd lcd tv's and a old crt monitor and the crt monitor looks so much better than the lcd, its just i have a ps3 and it only outputs 16:9 in hd settings.
