| Mar 10, 2017 at 12:36 | comment | added | n1000 | @ThomasTempelmann Thank you so much for these reflections. The "dongle trick" and the fake dongles you can buy at Amazon were initially invented to speed up the remote desktop. My uninformed guess is that without it the CPU renders the image. After all I (sometimes) get a picture, as seen in the screenshot above. | |
| Mar 10, 2017 at 11:13 | comment | added | Thomas Tempelmann | Okay, then asking for "force-enabling the GPU" won't get you anyway, I believe. The hardware trick works because the GPU senses the line and therefore lets the OS know that there's a monitor, and then the OS activates the GPU. But whether the GPU is active or not may not be relevent to Screen Sharing. Instead, The OS needs to think there's a display. Just activating the GPU somehow would not make the OS think that. You'd only get irritated responses for that question, I think :) It's all about making the OS believe there's a monitor connected. Hence AirDisplay etc, which can do that. | |
| Mar 10, 2017 at 11:05 | comment | added | n1000 | That is what I gathered from the other discussions. Also the fact that the "dongle trick" works hints at that. This mac mini has only one GPU. | |
| Mar 10, 2017 at 10:48 | comment | added | Thomas Tempelmann | What makesyou think it has something to do with the GPU (I guess your Mac has both a simply graphic processor on the Intel CPU and a dedicated high-performance one, for games and such? I only know that from my MacBook Pro, my older Minis don't have that.) | |
| Mar 10, 2017 at 10:43 | comment | added | n1000 | @ThomasTempelmann Thank you for that. Using SwitchRes did not cross my mind yet. I will give it a try later today... Maybe I should ask another question on how to force enable the GPU. | |
| Mar 10, 2017 at 10:40 | comment | added | Thomas Tempelmann | I'd try SwitchRes and see if that helps, as it can mess with the available screen parameters. Alternatively, there are some other tools simulating or inserting screens that may help, such as AirDisplay and related apps. It may also help to add another video connector for a VGA or DVI display to fool the Mac into thinking there's an active display connected (oh, I see you already mention that in your answer). | |
