I haven't tried sending an AV signal from a PS3 using component cables.
DVD output *may* be restricted to 480p. All SD upscalers I've seen require an HDMI connection.
Blu-Ray would be limited to 1080i.
Supposedly, PS3 games can output at full 1080p if your monitor supports that resolution. My guess would be 720p/1080i.
Can't confirm that without trying it myself, but that's what users claim.
