Hi Jeremy, yes I have true p originated material, I work mostly with Red originated files or panasonic 3000 and both in 24p or 25p. My problem is not with the quality of the image, it looks fine, but with the black levels, that are too high and noisy even in a graphic image, such as a gradient and viewing it in a native rgb program like after effects or nuke.
On monday I will try to create a new rec 709 calibrated profile with the hp probe and see how it looks. but I’m not confortable doing this, as the monitor is already calibrated and I think that is the Aja HDMI output the culprit here.

Thanks a lot for taking and interest trying to help me whit this issue.

Thanks for your reply Gary, yes I have set the HDMI preference to RGB and tried both, Full Range and SMPTE in the drop box next to it, sorry I don’t recall how this preference is called.

I have tried this with red footage converted to prores, straight red footage in color and also a generated gradient in nuke which is allways RGB, and in all programs with the same result.

The HdLink always converts to rgb, and the only prefrence is for using true progressive intead of PFs, and I’m aware this is not the prefered way to do it, The HDLINK downsamples to 8bit, as dvi is only 8bit, that’s why I bougth the IoExpress, to use HDMI 1.3 straight of the IOExpress, going trough SDI and the HDLink was only a way to test if the problem was with all of the Aja outputs ore only with HDMI.

Before, I was using sdi out of a multibrige pro with the hdlink going to the dreamcolor via dvi, and it was working just fine, besides being 8bits of course, and thats the reason that I went to the aja, to use the 10bits out of the HDMI 1.3 as i said above.

I doubt it has anything to do with the cables, I have tried a couple, so I’m quite lost as what is causing the problem.

Thanks a lot for your help

Thanks Jeremy, but I was sending a true progresive signal in RGB, I’m not having a problem being able to access the colorspaces in the dreamcolor, is with the hdmi output in the aja IoExpress that doesn’t seem to send a proper signal using hdmi, the monitor is already calibrated and works right if I go via sdi from the aja and use hdlink to convert to dvi.

Best regards
