Re: IO Express HDMI out not working properly

[Jorge Torrens] "[gary adcock]First - The 1.0 Release version of the Io Express software does not support RGB V-out from any the animation sources you list. So there is some color conversion going on in your workflow that is not being accounted for....

I clearly understand that, What I was meaning is that using nuke and a gradient generated in nuke it would be by definition a progressive rgb image, so it would not be any extra conversion from yub to rgb or psf to true progressive, and would be one less thing to consider."

OK - the IoX does not support RGB video out- so something is doing the conversion from your Nuke file to YUV- it is NOT the hardware.

[Jorge Torrens] "Exactly the same problem, the black level is to high. If I adjust the black level in the monitor as per Jeremy's suggestion I can get an image that looks fine, but it kind of defeats the porpouse of having a calibrated monitor, doesn't it? "

Isn't that what calibrating a monitor is??- adjusting it so that the viewing space is a close to correct as possible? Correct calibration of BroadcastVideo monitors is done using the "blue only settings" while viewing 75% SMPTE Color bars.
