I have tried re plugging the mini dvi display port adapter and have tried using a different monitor with a different monitor cable.
Macbook pro displayport adapter not working.
It was a usb c to displayport adapter after which i used a displayport cable to connect it to my external uhd monitor philips brilliance 288p.
If your display has more than one video connection see if using another connection on the display works.
I have connected a mini displayport to vga adapter in order to show presentations on different lcd projectors but no image appear.
If possible check to see if using a different display or a different adapter works.
The external monitor is detected but no image is shown.
Definitely make sure you use a true thunderbolt cable with a thunderbolt icon on it and not a random old mini displayport cable with a rectangular monitor icon.
I bought 2 new macbook pro 13 2 9 ghz intel core i7 with 8 go 1600mhz ddr3 intel hd graphics 4000 512 mb mac os x lion 10 7 4 11e2617.
For example a mini displayport to dvi adapter can t be connected to a dvi to hdmi adapter.
A bit ago i purchased myself a macbook pro 15 2016.
The macbook pro was running sierra as operating.
If you re using a mini displayport cable with a mini displayport display use a third party usb c to mini displayport adapter.
Another question will be whether your macbook pro can actually support a 4k device at full resolution.
The thunderbolt 3 ports in the macbook pro and macbook air work with usb c devices which have the same connector shape.
This is the correct solution for the apple led cinema display.
Try using a different cable that you know is in working order.
C to displayport cable or adapter.
They have the same connector shape but not the same capabilities.
Mini displayport is not the same as thunderbolt or.
Using the detect displays does nothing.
I purchased an adapter so i could connect it to my external monitor which functions perfectly.
