50hz

I had some issues with performance on a system that was solved switching to refresh rate. The projector boys told me their input had to be 60Hz. Changed it to 75H and using 1024 x 768. This was on a Barco R18.M

Performance issues are something else.

There is a bug in opengl after about osx 10.3.5 which requires the installation of the ATI displays control panel and software.
otherwise 60hz doesnt work well, but 75 works fine.

Did you check this?

I have been using R12s lately always at 75hz and no issues.

try doing a very fast strobe- one frame on one frame off.

This is NOT a problem with normal usage at all.


just doesnt work well with projectors that do internal processing in a certain way.
