Just wondering if the Barco 808 Graphics CRT front PJ is progressive or interlaced? I have no idea, as I'm not familiar with CRT front projectors. Are they progressive like a PC monitor? Or interlaced like NTSC TV's? I'm thinking maybe the HDTV CRT front projectors are progressive but I don't know. thanx P.S. The reason I am asking is because I am curious as to whether an iScan HD would make sense with this unit. If its interlaced, I don't imagine that the iScan HD would make much sense.
