    There are simpler solutions like this one:

    It has a weird caveat: On a 27" Cinema Display or iMac it only outputs 1280x720 due to limitations of the employed HDMI standard.
    (exactly half of the native resolution, so in essence it's the retina effect in reverse, you get very big and blocky 4-pixel pixels, but at least it's without scaling artifacts)

    On a 24" Cinema Display you get the full 1920x1200 resolution.

    I have two of these and tested both cases and can confirm it's working as intended. I connected a 2007 Macbook Pro with DVI-I output to a 27" Cinema Display this way, and a Raspberry Pi 3 to a 24" Cinema Display.
