Review on 🖥️ DTECH HDMI Dummy Plug 4K Display Emulator: Enhance Compatibility on Windows, Mac OSX, Linux (fit-Headless, 3 Pack) by Sean Webb

Three units arrived as described. The manufacturer had a quality package with all three packed in a single protective zipped bag. (I know there's a name for it, but it eludes me). One hooked up to an old Retina laptop and the other two were headless miniatures by mid-2011. Now I get 1080p on two minis and 4096x2160 on a powerbook. Actually I have to resize it to 2560x1440 on Powerbook to fit my monitor. Bonus, the Powerbook can remain closed and still active. Mini 2011 are servers. I still remember the screen size of my original 1984 Mac being 512 x 342.
