I have MacBook Pro (late 2013) and I'm considering getting Dell U2515H QHD monitor. The MBP has two Thunderbolt ports.

The monitor supports DisplayPort and DisplayPort 1.2.

Which adapter I need to get in order to use the Dell U2515H with my MBP?

  • The thunderbolt is backwards compatible with displayport so a normal displayport cable works fine. – Hoshts Jan 23 '16 at 14:23
  • The MacBook Pro only has two Thunderbolt ports, not three. – user3439894 Jan 23 '16 at 14:28
  • @Hoshts So this would work ? amazon.de/Patuoxun-Thunderbolt-Displayport-Microsoft-Thinkpad/… – Chiron Jan 23 '16 at 14:28
  • @user3439894 True, my mistake. – Chiron Jan 23 '16 at 14:28
  • @Chiron You should not need any adapter at all. The Dell U2515 comes with a dp-to-minidp cable. – Hoshts Jan 23 '16 at 14:31

The MacBook Pro Thunderbolt ports are fully compatible with DisplayPort so as long as you have a DisplayPort cable, there is no need for an adapter.

I own 2x Dell U2715H myself. Dell is so nice to deliver their display with the needed cable. Working like a charm and I love the displays.

  • Which MacBook Pro do you have ? I have rMBP late 2013 and the U2515H is not working :( Constant black and white flickering and it is not working at all when pressing any key while the laptop is sleeping – Chiron Jan 27 '16 at 19:48
  • Flickering? Sounds bad tbh. If it doesn't get a signal it should say that, like when cable is unplugged, but flickering?? Do the OSD work on the display? When the input select is showing, try hold the accept button for about 8 seconds. A modal should come up saying something about DisplayPort. Try enable/disable that (it is for DisplayPort 1.2 if I remember correctly) – Hoshts Jan 28 '16 at 0:25
  • Btw, did you use the mbp with an external display over DisplayPort earlier? – Hoshts Jan 28 '16 at 0:26
  • I didn't try my rMBP with any external monitor before. I'm having this exactly youtube.com/watch?v=OTIdH1KtJDk – Chiron Jan 28 '16 at 8:50
  • It was very depressing. I returned the monitor. Looks like 13 inches late 2013 aren't supporting higher resolutions. 15 inches late 2013 do though ! – Chiron Jan 28 '16 at 8:51
