Q: Early 2013 MBPr max resolution for Dell U2713HM

Hello,

 

I have a 15" 2013 MBPr (running 10.11.5) and am having difficulty getting the computer to output at the 2560x1440 resolution.  I know this is possible because I got it working once but after a reboot, I am stuck at 1920 x 1080.


I know that this resolution is only supported on DVI and DP on the monitor and I am using DVI so  I have that covered.  Also I got it working once (I'm not sure how) but after a reboot I can't get that resolution back.

 

I am using the HDMI->DVI apple adapter to connect it, but I have also tried the TB->DVI connector without success.

 

I also know that the cable is ok because I use the cable to connect to my PC and it can output 2560x1440 to the monitor.

 

Would anyone have any ideas on what I can try to fix this?  I have spent a small fortune on different cables and now I am convinced this is something to do with the MBP and not the monitor or the cables.

 

Thanks,

MacBook Pro (Retina, 15-inch, Early 2013), OS X El Capitan (10.11.5), Dell U2713HM
