CRT Projection and 72/75Hz

post #1 of 3
Thread Starter 
Hello guys,

how many people are using 72/75 Hz on their CRT Projection systems?

what experiences do you guys have with the different HDMI solutions

out there? (Moome, HD Fury , ...)

ad any problems with syncing to the higher bandwidths?

I do have a friend that just got the latest HDMI card for a Barco 1209s
and he's got a lot of problems with it concerning 72/75 Hz.

any insights appreciated

I don't know if this is relevant or not, but I have a NEC XG-750 (75 KHz max. scanrate). I have issues related to sync (banding) on straight 1080p60 from HDfury2, but I discovered that if I run it through my video processor to combine the horizontal and vertical syncs to composite sync, the problems go away and it looks perfectly fine.
Running 1600x1200 @ 60 Hz from a PC's VGA output did not cause the same issue and I was able to use the separate sync just fine that way.

Our Barco modifications really improve 3d response according to our customers.

The old 800 MHZ opamps used in Barco Cine9 / 909 is replaced with a much more modern faster 2.4 GHZ chip in the video chain that reduces the ghost effect.
