David-thanks for the reply.
You’re feeding SD from the 2100D, perhaps the projectors are set to HD?
We are running the projectors in standard def.-the RGBHV input has been in use for some time. We’re going in the DVI input.
I’ve been through the X2 setting in the EDID override w/o effect-I wonder if the projector is being “fooled” by the HDLink into a certain resolution which I need to override?
