Very simple problem: I am trying to hook up a laptop to a projector via a Mini DisplayPort to VGA connector, however it just doesn't work at all. Where this gets odd is: • This all works to the second monitor on my desk - thus the Mini DisplayPort, OS/Drivers & adapter are working. • This all works if I take the VGA cable from the monitor and plug in the projector directly this would imply a cable issue to the projector.

Use the Mac mini’s HDMI port to bypass the eGPU when booting into macOS. Shut down your Mac mini. Windows Update driver install status. Disconnect the HDMI cable from your Mac mini and the. To use the new 27-inch iMac as an external monitor requires a very specific cable to work: a Mini DisplayPort to Mini DisplayPort cable, to be exact.

• Other laptops work with the normal monitor VGA cable albeit without the adapter, seems to eliminate a catastrophic the cable issue. • There are no pins missing from the projector cable. • The projector is pushing out the plug & play info. • Tried on a second projector with similar config and same issue occurs. This leads me to think an issue exists between the combination of the adapter & cable.

The only key difference I can see between the screen cable & the projectors cable is length (projector cable is much longer) but still. The question I have is how to get this working?

If you have next steps in troubleshooting, I would love to hear those too.

Many people seem to have an issue with linking laptops with Mini DisplayPort output to projectors with VGA input. Here's the real solution to my similar problem: I purchased a Dell XPS 8700 one year ago: • Windows 7 Home Premium • NVIDIA(R) GeForce(R) GTX 650 Ti 1.0GB GDDR5 card I paired it with a Dell 1610HD projector, using its stock 6 foot VGA to VGA cable, and an Apple Mini DisplayPort to VGA adaptor from Best Buy.

I had no problems for a year, maybe twenty PowerPoint presentations. Then, the projector failed to detect a signal from the laptop. I tried all the usual techniques on the laptop: • cycling through the displays with the F1 key • rebooting etc.

After reading online posts, I believed that my adaptor was broken, so I purchased a Rocketfish brand. So, I purchased the Dell brand.

What, I wondered, were the chances that three different manufacturer's products were defective? Not very high. I reasoned it much more likely that the problem was with the Mini DisplayPort module, itself. Most likely, the more it is used, the 'looser' it becomes, making the connection with the adapters more tenuous.

So, I did an experiment. SOLUTION: In sequence': • I turned on the laptop • I then turned on the projector • I connected the VGA cable to the projector, and the adaptor to the cable. • I used the F1 key on the laptop to toggle through the display choices to the 'Duplicate' mode. • The display on the laptop then shrinks horizontally, and says that this is isn't the optimum display resolution. I ignored that. This also works with the 'Extended' mode, and the warning about resolution isn't displayed.
