Connect PS3 on 21.5" iMac?

[Zenor]

Hello everyone,

Would it be possible to connect a PS3(or PS3 slim) to my iMac 21.5"?
I want to use the iMac as a monitor for the PS3 in order to play games.

Has anyone tried it before, and if so what are your results?

It's possible with EyeTV but it only gives you 480p and it lags a lot (=not playable). Unfortunately only 27" can so far be used as a display as well with an expensive adapter.
