I'm having issues using an external monitor with my 2011 17" MBP. The screen is a Dell U2713HM, 27" 1440p monitor. I've connected it using a mini DisplayPort to DisplayPort cable, connected to the Thunderbolt 1 port. It only displays the screen when outputting certain resolutions, but not others. For example, I'm currently using it at 1600x1200, however it will not run at 1600x900, or 2560x1440. The screen immediately enters power save mode when I choose these resolutions.
Obviously I would like to use the screen at 2560x1440.
I also have the screen connected to my home desktop via DVI, where it works perfectly.
Does anyone have any suggestions about what I could do to figure out what's wrong?
