Just a wild guess, but maybe Kaur Hendrikson might be able to help you out with that specific task...

Just tried some tests with the HDMI output to an Eizo monitor and the SDI output to my main OLED monitor.

1080p/25 project loaded in Resolve.

The 'use 4:4:4 SDI'  option seems to feed RGB to both outputs. 

The Eizo doesn't always correctly identify this consistently in Auto (for it's Input Color Format) so I set this to RGB.

You can separately switch the SDI output to Y, Cb, Cr 4:2:2  in the Desktop Video and this doesn't effect the HDMI output, although switching from 1080p to 1080 psf does seem to effect both outputs.

Switching the Data levels in Resolve from 'video' to 'full' effects both outputs. The 'auto' setting in the Eizo 'Input Range' doesn't seem to identify the signal level, so you have to set this manually.

I've found that sometimes switching back and forth between the Resolve settings and the Desktop Video settings, can cause problems with a setting not 'sticking'. In these situations you have to go away from a setting (say, the 1080p/1080psf) and then come back to it.

But in conclusion, I could get my OLED reference monitor to display Y, Cr, Cb, 4:2:2 video levels and my Eizo monitor to RGB with video levels with the combination of 'Use 4:4:4 SDI'  (Resolve menu) and 'Video is converted to Y, Cb, Cr 4:2:2' (in Desktop Video menu).

 

 

Thank you for experimenting and testing! I'm still not sure what to do with the "Use 4:4:4 SDI"-option. As I mentioned it behaves the same (increases brightness a bit), regardless of what I set the SDI Output in my UltraStudio settings, which makes sense, since I use the HDMI-output.

I've set the monitor to RGB, Matrix auto and and the input range to full; Resolve is set to full, too. I generated an SMTPE chart within Resolve's generators and experimented with the "Use 4:4:4 SDI"-setting.

Switching "Use 4:4:4 SDI" on makes the image a bit brighter and makes two small bars on the bottom of my SMTPE chart visible. Looking a my scopes, I should indeed be seeing these two bars, since they are clearly elevated from 0 IRE... turning "Use 4:4:4 SDI" off makes the two bars invisible... this happen in full/full and video/limited.

I guess I'll probably leave "Use 4:4:4-SDI" on for the moment...

What's Blackmagic Desktop Video Setup saying your output is set to?

I've found that to be the main determiner of what comes out of the Ultrastudio 3G monitor

Even when using HDMI and not SDI? My UltraStudio 3G is set to 1080p25 in the General tab.

Under SDI-Output I could switch the color space between "RGB 4:4:4" and "Y, Cb, Cr 4:2:2" and the 3G-SDI format between "SMPTE Level A" and "SMPTE Level B"

Hi there,

I'm working in Resolve on a mac with a cleanfeed to my EIZO CS2700s via an Ultrastudio 3G over HDMI. Regardless of whether I set my monitor's input range to "limited" to match Resolves' Data Levels set to "video" or set both to "full", ticking the "Use 4:4:4 SDI"-option in Resolve (project settings --> master settings --> video monitoring) results in a huge brightness-shift.

So that left me wondering whether I should check or uncheck the "Use 4:4:4 SDI"-option and why it's even altering my signal over HDMI? 

Thank you for your help - I'm really confused at that point...

Cheers, Flo

My apologies, it is not. I got swamped with work and also got hit with an ongoing illness, so it's a question of when I can get time.

Thanks for replying @Marc Wielage.

No worries! I wish you all the best and hope to see you/ read from you here at lowepost!
