MacBook – 2560×1600 on Dell U3011 with new MacBook Pro

macbook pro

I have a brand new MacBook Pro (Mid 2014) and a Dell U3011 30" display.

Is there any way to get the full 2560×1600 resolution on the Dell without the $100 Dual-Link DVI adapter?

I've tried HDMI to HDMI and Thunderbolt (Mini DP?) to HDMI, but I can't get more than 1920×1200. I've also tried resetting NVRAM/PRAM.

Try using the mini Display Port to the Dell's Display Port.
That's how I connect to 2 2560*1440 Dell screens.

I've found, in order of reliability

  • Display Port - works every time
  • DVI - works most of the time, can be fussy on some screens
  • HDMI - haven't used
  • anything > VGA [barely works at all on anything over 1920*1200]
