A few days ago, I received a cryptic message from an Australian reader (a countryman of Blackmagic, but apparently not a Blackmagic Design employee). It said: “Looks like Blackmagic have removed the Band-Aid. Latest software supports RGB 10bit on HDMI!”. I immediately downloaded the ReadMe for the latest update to Blackmagic’s Desktop Video Software, which also automatically updates firmware when appropriate. I had a couple of questions and contacted Blackmagic PR. Ahead are the critical details you need to know.
What’s a “Band-Aid” in this case?
As covered in many prior articles, a “Band-Aid” in this case is the requirement for a device called the HDLink Pro 3D DisplayPort from Blackmagic in order to fulfill the original DreamColor Monitor’s DreamColor Engine to work, since that Engine demands pure progressive (no interlaced or PsF video) and RGB only (no YUV). Although not required to function, it is still better to send RGB even to the new DreamColor Monitors if possible. That way (in the case of use with a project or timeline that is already RGB), less processing will take place, as long as the interface allows for pure RGB from the source on the project or timeline to HDMI.

Relevant quote from the Desktop Video Software ReadMe
The original ReadMe from June 6, 2014 stated:
10-bit RGB support on HDMI in all HD modes.
Unfortunately, this line wasn’t totally true for all current Blackmagic products, as you’ll see ahead.
I requested an official statement from Blackmagic public relations department in the U.S. They responded with:
We are always working to improve our hardware and have our products reach their full potential. Full support for HDMI RGB displays such as the HP DreamColor monitors is an important addition.
My additional question, and the response
With a device like the UltraStudio Mini Monitor when used with DaVinci Resolve (where the material is already RGB/4:4:4), will the path from DaVinci Resolve to the UltraStudio Mini Monitor's HDMI port now remain as pure RGB/4:4:4… or does the hardware design of the UltraStudio Mini Monitor still force a conversion from RGB/4:4:4 to YUV 4:2:2 and back again to RGB/4:4:4?
The sad response was:
The UltraStudio Mini Monitor does not have the capability to support 10-bit RGB over HDMI. The feature was only included on the Desktop Video 10 devices (4K products). It will still do the conversion to YUV.
I asked for verification, given the way the ReadMe was written. The PR contact double-checked and said that the lack of RGB over HDMI on the UltraStudio Mini Monitor was indeed true, and that the documentation would be corrected to reflect this.
I am delighted to know that after several years and 241 electronic signatures (and counting), some DreamColor Monitor users can now rejoice and sell their Band-Aid and simplify their system. However, I wish the update covered all Blackmagic products with HDMI output, the way many of AJA’s, Matrox’s, and MOTU’s products that include HDMI have already done for many years. However, if you are going to use DaVinci Resolve either for video grading (or with recent versions, even to edit video), then the only way to see your program out on a program monitor correctly will be via a Blackmagic interface, not one of any of the competitors. So those who have a DreamColor Monitor with one of the “chosen” Blackmagic interfaces will now be able to remove their Band-Aid, sell it, and simplify their system. Those who have the other, “non-chosen” interfaces must keep the Band-Aid, at least for now. Purchasers of new interfaces for new systems will now have a greater incentive to purchase a higher-end Blackmagic interface model that now supports RGB over HDMI directly (aka the UltraStudio 4K), rather than a lower priced one like the UltraStudio Mini Monitor together with a Band-Aid. In fact, some users who currently use an UltraStudio Mini Monitor together with a Band-Aid may be tempted to sell both, and replace them with a single interface that handles everything for that. If Blackmagic ever adds RGB over HDMI on the UltraStudio Mini Monitor, I’ll be letting you know on this same channel!

My most recent book is available in two languages, and in paperback as well as an ebook. The ebook format is Kindle, but even if you don’t have a Kindle device, you can read Kindle books on many other devices using a free Kindle app. That includes iPad, Android tablets, Mac computers, and Windows computers. Although generally speaking, Kindle books are readable on smartphones like Androids and iPhones, I don’t recommend it for this particular book since it contains both color photos and color comparison charts. The ebook is also DRM-free.
