Macbook Pro Displayport Adapter Not Working

C to displayport cable or adapter.

Macbook pro displayport adapter not working.

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. The macbook pro was running sierra as operating. Try using a different cable that you know is in working order. They have the same connector shape but not the same capabilities.

If you re using a mini displayport cable with a mini displayport display use a third party usb c to mini displayport adapter. I have connected a mini displayport to vga adapter in order to show presentations on different lcd projectors but no image appear. If your display has more than one video connection see if using another connection on the display works. Using the detect displays does nothing.

It was working fine a few hours ago at work i got home and plugged in the external display as usual and turned on the machine and nothing. The thunderbolt 3 ports in the macbook pro and macbook air work with usb c devices which have the same connector shape. A bit ago i purchased myself a macbook pro 15 2016. 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. For example a mini displayport to dvi adapter can t be connected to a dvi to hdmi adapter. Check with its manufacturer for compatibility with your mac and display model. This is the correct solution for the apple led cinema display.

Another question will be whether your macbook pro can actually support a 4k device at full resolution. A 61 watt power adapter. 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 possible check to see if using a different display or a different adapter works.
