problems with 1920 x 1080p

[Gian]

We used here just fine

1920 x 1080
or
1920 x 1200

during set up today we tried to run Cat1 output one at 1920 rather than 1600, both attached monitors were ok at 1920 ( one FOH via Cat5) but the Image Pro still seems to have issues... Black seems to have a green cast over it and White seems to have a purple tint?

run everything at 1600 and everything is happy?

Ian,

What model Image Pro are you using...SDI?....HD?

Are you seeing this issue when you hook up a monitor to the passthough port on the Image Pro? or only at the projector?

It sounds to me from your description that it might be either a Gamma adjustment issue or the polarizers in your projectors.....odd that it goes away at a different resolution though.

Have you tried swapping out your Image Pro for another to rule it out?

purple green hues sounds like a yuv sampling problem- a phase shift -
something isnt sampling the image correctly-

means something has gone wrong in the electronics - probably-
if it works at 1600 the bandwidth of the signal is lower.

thanks Richard.

When we get the cats out of their cage after our day off. i will run some perms with our two cats and 3 HD Image Pros...

I did see the same thing in MIA on one of our US friends new spec cats when we tried 1920 direct to a Barco PJ via the TL fiber kit..again only at 1920 problem, change to 1600 no problem.

I am running four Cats into image pros into a router-switch-router and on to Barco HD 18s with no problem at 1920x1080. I am running everything legal and in time at 59.94 interlaced. Cats are outputting 1920x1080p @ 30.
