Millumin with AJA HA5-4K to multidisplay

Hi, 

Now I try to the multidisplay in Millumin.

I create 4k resolution screen (3840x2160) on a display. And I use the AJA HA5-4K to separate 4 displays with MAC PRO ver., 10.9.
But it doesn't well, like the positioning of display do not fit to the 4 screens.

Does AJA's scaling not well ? Or because of the setting onto Millumin ?

    Hello @YOKOTA,

    From what I understand, you are using a AJA HA5-4K to convert a stream via HDMI 4Kp60 into a stream Quad 3G-SDI 4Kp60 : am I right ? (see there for an explanation of the Quad 3G-SDI stream)

    I do not think the problem comes from Millumin at all :
    - Is the AJA HA5-4K recognized by your Mac as a 4Kp60 display, 3840x2160 pixels ? (See macOS System Preferences / Displays)
    - Did you check the options of your AJA HA5-4K ? Quad 3G-SDI is meant to use 4 x 2Kp60 streams (for each quarter of the image), but as far as I know, it is not a standard and each manufacturer can have its own implementations/options.
    - Lastly, did you ask AJA support ? I guess, they are the best to provide answer on this topic.

    Best. Philippe

    Hello Philippe,

    Thank you your quick response!

    Ok, I understand the problem, like you say, I think it's not because of Millumin.
    I will ask at AJA.

    Thank you.
