Beamer delay

Postby duckprinter » Fri Jun 06, 2014 8:18 am

Hey,
I have a Viewsonic projector (pjd7820hd) and noticed at my last print, that it has a delay to show the slice or show blank. The problem was that the machine lifted before the projector showed blank.
I solved it writing a "<delay> 500" between the <blank> and the lift command.
Did someone notice something similar?

I had this problem when I was running CW on my old netbook, and I did the same exact thing with adding a half second delay! The problem went away completely when I switched to a more powerful computer. You wouldn't think that CW would be that resource intensive, but maybe it isn't releasing the memory and cycles it needs for the 3D rendered screen when you switch away from it?

I also had this issue when I was using VGA on my old Dell laptop. Switched out to HDMI and hasn't been a issue since.

Thanks for your help. It should be the VGA-port. At the moment I have to stay at this configuration because my laptop doesn't have a HDMI-port.
