It should be noted that all original units (“HDLink Pro DisplayPort”, without the “3D” indication) magically became 3D upon applying this update (or a later one). I am grateful that several months after I discussed this issue with Blackmagic in 2009, they added the capability of deactivating EDID in the HDLink Pro 3D DisplayPort starting with firmware update 3.4 on July 15, 2010. That is not good for editing or grading, unless you happen to be editing or grading exclusively at the quite uncommon 30.000 fps or the equally rare 60.000 fps.īlackmagic added the capability of deactivating EDID in HDLink Pro in mid 2010 If EDID is active, when inquired the DreamColor monitor will respond: “My favorite is 60 Hz!” and the device will unfortunately feel obliged to convert everything to that rate. Why EDID is bad for the DreamColor (or other monitor) in an editing or grading situation?Īs covered in several prior articles, when editing or grading it is ideal to monitor at the same framerate as the project, or at a multiple of that framerate if it is low (i.e. In fact, the original version of the product -called “HD Link Pro DisplayPort” (without the “3D” indication)- came with the EDID constantly active. not editing or grading) since the unit ships from the factory with EDID active. Apparently, Blackmagic markets and sells the HDLink Pro 3D DisplayPort device in greater numbers for other target uses (i.e.
Outside of editing and grading applications, EDID is usually good because it allows a computer to deliver the monitor’s ideal spatial resolution and its ideal refresh rate (akin to framerate) as long as it is available from the GPU. EDID is defined by a standard published by the Video Electronics Standards Association (VESA). It is what enables a modern personal computer to know what kinds of monitors are connected to it. …a data structure provided by a digital display to describe its capabilities to a video source (e.g. If you are new to my articles, you might want to review Blackmagic: We’re ready to remove the Band-Aid! from May 2012.ĮDID is an acronym for Extended Display Identification Data, and has been defined by Wikipedia as:

Ahead I’ll define EDID, explain why it’s so important to deactivate it, and show you exactly how to do it. However, I haven’t yet covered how vital it is for the user to deactivate EDID in the HDLink Pro 3D DisplayPort to achieve proper system operation. (23.98 PsF = 47.96 Hz)Ģ Changing the HDLink Pro 3D signal setting from YUV to RGB is required because the DisplayPort of the monitors do not support YUV.I have clarified in prior articles how essential it is for DreamColor monitor users who also use an i/o device from Blackmagic Design to purchase an HDLink Pro 3D DisplayPort as an accessory (“Band-Aid”) to satisfy the DreamColor Engine’s absolute requirement for RGB/4:4:4, at least until such time as Blackmagic updates its firmware/software to allow for this signal over HDMI. PsF (Progressive segmented Frame) means Interlace signal. Plugging and unplogging the power cable may improve the image. Image noise may occur especially in 24 and 25 Fps.
