Connecting the EX3 to the Apple 30" Cinema display
 

I was wondering if there is a cheep way, under 300$ to monitor the EX3 on the Apple 30" cinema display in HD using the HD SDI output or some other output. I am doing it with the component out to a Dell right now but there is interference in the picture. I need about 25' of cable to get away from the camera.

Thanks!!!

This is closest. SDI to ANYTHING is NOT going to be inexpensive. You can go to HDMI but I don't see DVI.
Blackmagic Design: Mini Converters

Maybe this at about $680
AJA | HDP SDI to DVI-D Converter - HD and SD Input | HDP | B&H

Take a look at Blackmagic Designs HD Link.

According to the specs tab, the max output resolution on that is 1920x1200. Apple 30" is 2560x1600.

Similar problem here. It looks like you need HDLink Pro ($495) if you want to output to a 30" computer monitor (dual link DVI). As far as I can tell, the regular HD Link can only use single link DVI. The standard HD Link seems to be discontinued now though, so if you have a 1920x1200 monitor, maybe this is a good way to get a cheaper converter, and it looks to be more compact than the HDLink Pro too, if that matters to you.

I don't know if the 30" Apple monitor can scale up 1920 res video.
