I currently have a DELL U2713HM monitor with a Max resolution of 2560 x 1440. What DELL doesn't mention on their website is this resolution is only supported via DVI-DL and DisplayPort.

The max HDMI resolution for the U2713HM is 1920 x 1080 @ 60fps. You can force the monitor to accept HDMI at 2560 x 1440 @ 30fps but it looks rubbish (at least from my graphics card).

Due to in wall cabling I may need to hook up my computer to a monitor via HDMI, does anyone know if the DELL U2713H can display 2560 x 1440 @ 60fps via HDMI without any hacks?

Note: The cables I have are HDMI 1.4 so they support this resolution. There are also other monitors out there that support 2560 x 1440 natively by HDMI (http://www.asus.com/au/Monitors_Projectors/PB278Q/#specifications)

This is not simply a Dell limitation, it is entirely a limitation on single link DVI and HDMI. You have found the only real solution (30 hz) and if you want full resolution at 60hz you need to recable. –  Mokubai Jun 13 '13 at 20:59
    
I believe HDMI (1.3 and above) does support 2560 x 1600 @ 60fps over a single link (see en.wikipedia.org/wiki/Hdmi#Version_comparison), its just whether the hardware supports. –  CuberChase Jun 13 '13 at 21:19
    
If the monitor does not support HDMI 1.3 (sounds likely) then my comment still stands. –  Mokubai Jun 13 '13 at 21:54
    
Another forum link on the same problem. –  dma_k May 20 at 9:28

There is somewhere in Dell's specification that it has HDMI limited to FullHD even when HDMI 1.4 supports higher resolutions. I don't think you will be able to change that. I had also this monitor and I had to buy (10 euros) DisplayPort cable (since DVI is used by my second smaller monitor).

BTW: DisplayPort cables use to be very thin so it may not be so big problem to replace existing HDMI in wall.

Thanks. I couldn't find anywhere in any DELL documentation or the website that states this. Provide me the link and I'll accept –  CuberChase Jun 13 '13 at 21:49
    
I remember I read it somewhere... looks like here: superuser.com/a/226333/184761 (I know it's different model, but I believe the reason is same :) ) –  klerik Jun 13 '13 at 22:26
    
And also other high resolution models (made by Dell) has similar limitation: prad.de/en/monitore/review/2012/review-dell-u2713hm-part3.html –  klerik Jun 13 '13 at 22:31
    
Thanks very much for that prad link, they reviewed the monitor I have and had the same problem, I looked again at the DELL documentation and couldn't see it stated anywhere and also the prad review for the U2713 and they don't mention the problem so I'm hoping its possible but would like to confirm it. –  CuberChase Jun 13 '13 at 22:49
