ThunderBolt/ minDisplayPort EDID emulator Plug, Headless Mac-mini 2560x1600, Ghost

Used 2 of these to adjust my remote VNC session screen dimensions to suit. Installed 2 of these (mDP-DDP-2560 mDP EDID emulator Plug 2560x1600 max Resolution 20171 92600) in my 2010 MacPro 5,1 VNC server running headless (no monitors) Mac OS X 10.10.5. Graphics card is ATI Radeon HD 5770. Have configured the headless output screen to look like 1 large wide display so that I access the system by VNC and the headless system displays the 2 headless monitors as 1 continous desktop across 2 monitors on the VNC client. Client is another Mac Pro 5,1 but I think the client configuration does not matter. Works great. Mac OS X 10.10.5 sees each of these as 1 monitor with a slew of resolutions you can choose from. Many but not all possible resolutions are available. Bought it 7/19/2017. Running 2 months with zero issues. Love it - 5 stars.

Exactly what one needs in a headless accelerator. My mac acting as a server just got a nice boost in responsiveness and I can unhook the old monitor. Clever product. I chose this over OWC and am glad I did. It is lower profile.

Works as described.

These tiny emulators work very well on my headless Mac mini with Sierra OS installed for remote desktop work. A long list of possible resolutions are available at 30-60fps after installing the free Display Menu from the App Store (see attached picture). The reason for four stars? On a MacBook Pro laptop or iMac with built-in screen the mouse doesn't work well, if at all, when accessing the Mac PC remotely (at the time of this posting). However, on a laptop if you close the lid (essentially negating the built in monitor), the EDID adapter is seen via remote access as a single monitor, and at that point the adapter provides the same full-screen experience with a wide range of possible resolutions as seen on the headless mac mini. If I knew of a way to easily disable/re-enable the built-in monitor on the iMac, I would try that too. As it now stands, the built-in iMac monitor causes the mouse to behave erratically when trying to use the EDID adapter via remote screen sharing - as also experienced on a mac laptop with the lid open. I love the device on a Mac mini serving as the sole monitor (picture attached).
