I'm going to buy myself a new pc beginning of 2007 with (hopefully) a 30" lcd display.
What graphics card does the best job for the massive screen resolution of 2550x1600 px : the latest G8800 GTX of the quadro FX 4500 ?
Assuming you mean "2560x1600", yes, both the 8800GTX and R600 will output this resolution. They all have dual-link DVI ports.
As for 1080p, no, neither will drive it as 1080p - it will have to be upscaled to fit on the display - whether by the monitor or the card. I suppose you could force it to display on a 1:1 pixel map, but you'd be wasting approximately a third of the screen on black space.
I would imagine that 1080p video would look *amazing* on the 3007 monitor - it won't be any worse than a true 1080p screen (and will probably be significantly better) - but it won't be displaying in native 1080p. In exactly the same way as a 1080p screen won't display native 720p - it upscales.
As far as I am aware the 8800GTX has full support for HDCP.
I've heard that the nvidia 8800 doesn't do a full HD (1080p) on a 30" display like the 3007WFP Dell, when the movie is a HDCP content protected movie. Is this thrue ?
Will the new ATI R600 do a full 1080p together with HDCP ? Remember : it will be on a 30" display with res of 2550x1600px.
ya, 8800gtx wont support it on both link ports.. only one dvi link supports hdcp so it ll b hard for a 30" monitor to work out with those hdcp movies.. and also yes for ATI R600, That supports full hdcp.
