Hi I have a Viewsonic VX2025 (it's a 20in PC LCD that doesn't have HDCP).

I'm looking to connect my PS3 via DVI. I'm fairly certain that the PS3 should do everything just fine, except bluray movies.

Am I right?

I believe you are.

My Sceptre X42 42" 1080P LCD HDTV happily accepts PS3-sourced video as long as it isn't a BluRay movie, when I set the TV to DVI mode (no HDCP handshaking).
