I was not able to achieve full resolution through HDMI on my EVGA GeForce 560 Ti. I can only go up to 1080p. Looking at the graphic card spec, it has a HDMI port version 1.4a which support full resolution. From HDMI.org, a new cable is not required to support HDMI 1.4 (except for some specific features). I can only assume that monitor does not support full resolution through HDMI. Dell's website make absolutely no mention of the HDMI version this monitor supports... I made the test on Windows 8.

It works fine with Dual-Link DVI (which I use) and Display Port. Everyone who has problems is using HDMI, which is designed to only support resolutions up to 1920x1080 at 60Hz (1080p). HDMI does support higher resolutions, like 4K, but only at much lower refresh rates (30 herz or 24 herz). HDMI also supports frame-packing (for three-dimensional television) and other features commonly found in televisions but not necessarily computer monitors. HDMI was designed by the television industry, so it supports the resolutions and frequencies used by televisions, but not necessarily the ones found...

Or to put it in layman's terms - you should be using a cable and connection with a computer monitor that is designed for a computer monitor (DVI, Dual-Link DVI, or Display Port). Although there is a lot of overlap between television technologies and computer monitor technologies, they are not the same. So don't be surprised if a computer monitor has problems using a connection and cable that is designed for television when operating the monitor at resolutions or refresh rates that are not commonly found in televisions.

The macbook pro has no hdmi port but I tested using my notebook HP dm4t-3000. Its a 14" notebook with these specs: i7 dual-core 2.8ghz, 8gb memory, dual graphics of HD3000 and ATI Radeon HD 7470, Windows 7. Using the HDMI port and switched to 7470 discrete card, it can only show up to 1920x1080p. Tested with 3 types of hdmi cables that I have and not sure if its HDMI v1.3 or v1.4 but all hdmi cables shows up to 1080p max resolution only.

As others have stated, it only officially supports 1920x1080 via HDMI. I managed to get it to a full 2560x1440, but I had to create a custom resolution and I could only get it to 30fps. Not ideal, but it's acceptable for me. See my image and review for more info.

Was only able to go up 1080P@60hz by default ... I am using a gtx 670 for the test.
I did a custom resolution through nv control panel and it actually go up to 2560x1440 but it didn't look good at all. DVI and DisplayPort seem to have no issues with it.

I have the previous generation of this monitor. Full Resolution through HDMI is not supported on these. Dell decided not to include it in the firmware for the monitor as they did not see many people using devices on HDMI that would go above 1080p. As all dells come with at least on Displayport. If you have an active HDMI to Display port converter it would work coming from your video card to the monitor (your hdmi becoming displayport) as the monitor would see it as displayport. However, this only works if your videocard supports the HDMI versions and cabling as listed in everyone elses...

I've been VERY happy with my previous purchase and would consider purchasing this version as a 2nd.

No... You have to use something like DisplayPort in order to get full resolution . That's what I use... Works great... In my situation though, my video card has Display-port outputs. If yours does not, I'm not sure if you can achieve full res.

I have run 2560x1440x60.0 through an intel I7 directly with no problems over HDMI for about a year. The trick is in the Screen0 section of xorg I use Option "CustomEDID" "HDMI3: /root//root/fastedid.bin"
I made the bin file by grabbing the edid from what the displayport reported in hex and then converted it to a binary file like so:
Here is the hex edid, copy it into /root/fastedid.hex: » Read More
