Question: Can you achieve full resolution through an HDMI cable on this monitor? Some people say yes and some say no, so please test before you answer.
Document: Needless to say that having the 2560x1440 pixels makes for some fantastic resolution and desktop space.We drive this monitor with an nVidia GTX 760 using the displayport (we purchased an inexpensive displayport cable from Amazon after reading that it was necessary to achieve the full resolution at the maximum frame rate of 60 Hz).We had no issues with the quality so far (no stuck or dead pixels, no observable defects or dirt/dust).
Everyone should be aware that to achieve the full 2560x1440 you need to have a better quality DVI cable that has all the pins. If you look at the end of your cable and you see two groups of I believe 9 pins each it won't work. You should see a single solid block of pins extending all the way from the blade pin to the other side of the connector. Otherwise you will be limited to 1920 pixels.Theoretically HDMI should work as well.
I ended up having to order a dual DVI video card in order to have two of these running at full resolution. I guess the HDMI version that Dell is implementing on this monitor is not up to the current specs...very frustrating!I bought this monitor as a test with plans to purchase a second if everything looked good. Now, Amazon has a disclaiming stating that the product &#34;may have problems&#34; and they no longer sell it.
I have not personally noticed any bleeding or dead pixels mentioned by some of the earliest reviewers of this display, so perhaps those kinks have been worked out in the manufacturing. There are a couple of points worth mentioning regarding using this display with a Mac. You are going to want to get yourself a Mini DisplayPort to DisplayPort cable to be able to achieve the higher 2560 x 1440 resolution that this monitor provides. Apparently, HDMI cables will be limited to transferring at the lesser 1080.
Excellent monitor!Note to other buyers: in order to get the full resolution of this monitor your computer must be capable of it and you must select the appropriate cable that allows your computer to support that resolution. Read your computers specifications to find the answer on what you need to support this resolution.
The display looks fabulous - bright and crisp with minimal bleeding.Killer: it sells itself as a 2560x1440 display, and also says it has HDMI 1.4 (Yes, Dell, it says that in your supplied documentation!) which should be able to drive that resolution. Alas I could only get 1920x1280 on the HDMI, and this is confirmed by the documentation supplied by Dell.To get the full resolution you need to use the DisplayPort not HDMI.
I just wanted to warn people who want to use this with a laptop about the resolution. You cannot get 2560 x 1440 over HDMI with this monitor (even with HDMI 1.4). BUT, if you use an HDMI to DVI adapter, you can get the full resolution. The drawback is, you can only get a single-link DVI connection, so your refresh rate is limited to 35Hz. But 2560x1440@35Hz is still better than 1920x1080@60Hz in my opinion.
Crystal clear when using a mini-display port to Display port cable (Dual-link DVI-D is the only other cable that will give full resolution. HDMI is limited to lower resolution for this monitor).Very clear, crisp display.
Then I read user reviews here on Amazon questioning if it could display beyond 1080p on whatever type of input signal and I got concerned. One reviewer emphatically stated that it would in fact to full resolution over HDMI. Given Amazon's excellent return policy, I figured it was worth the try. Unhooked the S2740L, routed the new wires for the 2713, plugged it in to my still-running computer's DVI-D cable, and BINGO!
The screen goes into power saving mode when I try to connect to it via Display Port, the reasonable way of supporting it's high resolution. So now I am stuck with HDMI can not get the full resolution from monitor....
Answer: 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.UPDATE: I got myself a new HDMI v1.4 cable and I could not reach full resolution...
