I just sold one of two Barco 1609's I have. THe customer wants to run 47 Khz, or line tripling.


He's done some research, and crtcinema seems to think that the set scans from 15 to18 Khz, then from 30-32 and then 60-64 Khz, eliminating 47 Khz as being a viable scan rate.


Is this true? I've never heard of this, and while I can lug the uncrated 1609 into the basement to my quadrupler, I'd rather find out form someone here.


Are there any other sets that do not have a continuous scan rate?


Thanks!

Curt,


Unlike the Data and Graphics series, all of the Vision series projectors have a limited, non-continuous range stated for horizontal frequency capability. I don't know why they did it that way, but there must be something slightly cheaper about manufacturing a Vision projector to be able to do this. I bet the frequency detection circuit combined with software disallows the use of signals outside of those specified ranges, but I haven't tried it myself.


Can you take your lightweight quadrupler and a video source to the projector instead of the other way around? I don't think you would really need to project the image on a screen to initially see if it works for tripled. I'd sure like to hear what you learn since I have a pair of the older BV1600 units myself.

Oh, tick me right off! (but thanks Nick!)


I'm on the phone with Barco now to see what can be done about this...

Well, Barco says nothing can be done. I'm going to try and modify..;-)
