I have a U2711 monitor which supports 2560x1440, but I have not been able to output this resolution with the following connections -

HDMI (PC) - HDMI (monitor) - max is 1920x1080
Display Port (PC) -> DVI converter - DVI (monitor) (I am using only DP port on monitor for another setup) - max is 1680x1050

Is my only option DP to DP?

U2711 is notorious for not supporting 1440p over HDMI. You'll have to use either dual link DVI cable or DP.

Interesting that it's my monitor that has the limitation. Didn't even think that this could be the problem. Is this limitation mentioned in the spec somewhere?

I ended up buying an external video card (GT 1030) with DVI to solve the issue.

Straight from the manual (yes, it is still on Dell's support site)
Setting the Maximum Resolution
1.Right-click on the desktop and select Properties. 2.Select the Settings tab. 3.Set the screen resolution to 2560 x 1440 (DVI and DisplayPort) or 2048 x 1152 (VGA) or 1080p (HDMI, Component). 4.Click OK.

The HDMI version on that display is 1.1 as I recall. It has a max resolution of 1920x1080 or 1920x1200 (depending if its 16:9 or 16:10). I have Dell U2412M's that are also 1.1, they just happen to be 1920x1200 so I don't have the issue you do.

Just popped in the Nvidia GT 1030 and my max resolution with DVI is 1680x1050 (updated to latest driver). My previous PC had a Radeon R7770 and had an output display of 2560x1440 using the same DVI cable and monitor. Any ideas?

Final update. I was able to create a custom resolution with the GT 1030 to output 2560x1440 using HDMI.
