50hz

[tharding]

I use Barco DLP projectors - G5, G8, G10, R12 on a regular basis all running at 75Hz with no issues. And I live in a world of PAL.

I have however once had an issue with A Folsom Screen Pro not liking 75Hz.

I know they had problems on eurovision last year.
Cant remember what is was or how they solved it.

I have seen problems with the DL1 running at 75Hz.
It seems to have an internal buffer that works better at 60Hz. if you strobe it at 75hz you get frame glitching. this isnt noticeable with normal footage.

I am using Barco ELM R18s. I have a fairly constant flicker on a few lines at 1280x1024 75Hz. However, while it is noticable on the line-up grid, it is not noticable on the content I have at the momemnt. The content may change to be more graphic with more fine lines and that may show the flicker.
I do not have a lot of head room on the processing side, since I have to run sxga using photo jpeg at 60 sq. Thus I want to avoid running at 60Hz.
I have re-configured the grapics card to overide os settings, but seen no noticable change to the 60hz output.

could be some kindof active temporal deinterlacing in the barco processing?

They might have a deinterlacing algorithm which works with successive frames?

I havent seen the options available in the barco menus recently.
