Re: IO Express HDMI out not working properly

Hi Gary thanks for your time I really appreciate it.

I believe you are misinterpreting me, most likely due to my english, I understand perfectly how the dreamcolor works, I've been using it without problems for over a year, so I'm not worried about how to get it to work with a predefined colorspace. I'm not asking how to send a true progressive RGB signal to the dreamcolor.

My problem is exclusively with the black levels out of the HDMI output of the Aja IoExpress, and I'm seeing the problem irregardless of where the material originated or the application I'm using.

I see the wrong levels in:

YUV originated material, AVCIntra panasonic in FCP and color

RGB converted to YUV, RED to prores in FCP and color

RGB native, computer generated gradient in nuke

RGB native, Red r3D in nuke and color

[gary adcock]WHAT does the IoExpress/ Kona control panel say the video space is? not what you think it is- what does it SAY it is?

I'm positive that the settings in the IoExpress control panel are:

Protocol: HDMI

Color Space: RGB 10 bit

Output Video Range: I have tried both SMPTE Range and Full Range.

The way I see it is either the HDMI output from the Aja is sending the wrong information or the HDMI input in the dreamcolor does not work. And if the problem was located in the dreamcolor it would display the same wrong image when in rec709 colorspace, both with the aja, or when conected straight to the display card of the computer or with the multibridge, and it doesn't. The levels displayed with the blackmagic and the ones from the computer card are correct.

The reason why I've tried going through straight from the computer or via the hdlink is to make sure that is not the hdmi port in the monitor the one to blame.

[gary adcock]a 10 bit signal should show more detail and by-passing any LUT's that are being used in the default mode on the HDLink.

That is exactly the reason I would like to use the Aja for, a cleanest signal, one less conversion, and more detail in 10 bit.

Thanks again for your time and sorry for the lenghty posts as it's hard for me to convey clearly my problem in english.
