Dell U2311H: E-IPS, Full Adjustments, and DisplayPort
by Chris Heinonen on September 27, 2011 12:20 AM ESTFor years now Dell has been one of the few companies that consistently offers a range of displays using IPS panels for desktop displays instead of only the more affordable TN panels. Now with the availability of e-IPS panels, Dell has been able to offer even more models and lower the price all the way down to $319 for a 23” 1080p display.
The U2311H uses a very similar base to what Dell has been using for years that lets the monitor simply clip in, and allows for rotation to be used as a portrait display as well. The left side of the display has a pair of USB 2.0 ports, to go with the pair located on the bottom of the display. Also on the bottom of the display are DisplayPort, DVI, and VGA inputs, as well as the power input. Located on the front of the display on the right side are the menu control buttons that are unlabeled and nicely disappear into the bezel. The U2311H can adjust in height vertically and has both tilt and swivel adjustments as well, which should make it able to fit into most spaces. It might not be flashy but it gets the job done.
With all the above features, you’ll note that a few items are missing. There’s no HDMI port, making this less desirable as an all-in-one display for use with PCs as well as game consoles. There are also no speakers, though given the quality of most LCD speakers we don’t feel like we’re really missing out. In a similar vein, there’s no audio out, so if you were to use DisplayPort for carrying audio there’s no way to get the audio from the display to an external source. There are perhaps minor omissions, but most of Dell’s higher-end LCDs include such features and they’re worth pointing out. Here’s the full rundown of the LCD specs:

Can you post the calibration settings you used?Thanks!

I will grab the settings I used when I hook it up for the input lag test, but since the majority of the work is done with the LUTs in your graphics chip, and not in the display itself, it really won't get you that much of an improvement over the stock settings unfortunately.Zoomer - Tuesday, September 27, 2011 - link
How about a review of HP's line, the ZR24w, etc, or maybe even a comparison?Makaveli - Tuesday, September 27, 2011 - link
I own a ZR24w and I would love to see this. From what I have researched the HP screen uses a real 8 bit panel and would love to see this compared to the 6bit+AFC in this. I'm sure if the Dell 24 inch version is also a non 8 bit panel?TegiriNenashi - Tuesday, September 27, 2011 - link

I Love these monitor reviews. Thanks for working hard on this! I would REALLY love to see a comparison of the current monitor technologies (H-IPS; E-IPS; Samsung's newest tech; TN Panels; Discussion of diffrent styles of LED backlights etc....) and which monitor lines we can find each tech in. This is a very complex issue and actually very pressing for those of us amateur turning-pro photographers and graphic designers on a budget. I've even seen some 40"+ LED backlit Televisions that claim to use IPS technology that i've considered for a display mostly for the price per inch ratio seems so good. Any thoughts on why that might be a bad idea if they are IPS panels?fausto412 - Wednesday, September 28, 2011 - link
yes, i would like to see comparison of technologies...TwinIon - Tuesday, September 27, 2011 - link
I own three of these. Great monitors for the price, but wait for a Dell sale. I got mine for closer to $250 each.Displayport was a real benefit for me since I wanted to use the screens for eyefinity, which requires DP for at least one monitor. The ability to adjust the screens has also proved very important for eyefinity.

I remember in the last 12 mouth, another Dell IPS screen was reviewed here. I recall this monitor have also the same price and have a Genesys board inside to drive the lcd. It's perhaps the same monitor with the dvi port instead, So, I saw many reader comments say this ips lcd is bad. I prefer at this point to pursage a nice and bright used Apple Cinema Display HD 23" for the same price. I very happy with this screen and I'm not regrating to don't have buy the Dell one.I think the Apple Cinema Display HD 23" could be a good comparison monitor to compare with new incomers, if you could found one like new. It perhaps an old monitor but it certainly clash with the Dell offers.

Check out the NEC EA231WMi. It has since been discontinued for a newer model with a LED backlight, but I got it just south of $300. It suffers none of the issues Dell's E-IPS panels do. It can be calibrated to be quite accurate. In fact you can download a calibration file from TFT Central from their review. You can get .inf files for 75hz and 83hz over display port. There is no input lag or ghosting that I can detect and I play a lot of video games. The stand on it is epicly good. Simply put there are a lot better and cheaper E-IPS panels than what Dell offers. NEC is worth the look.
