If you’re a print designer or a photographer, this post is probably not very useful, but stick around and see if provided links can help.
Dell U2711 is significantly cheaper here in Croatia than 27-inch LED Cinema Display. It’s a smart alternative, especially if you don’t like glossy screens.
But are there any caveats?
Color-spaces for web design
Internet is all in sRGB, i.e. the relatively small color-space. This standard is brought by Microsoft and HP back in the days, to create a common denominator for consumer grade systems and it’s a default for Windows PCs.
I found this article a good starting point to understand differences between various color-spaces: Setting a Work Color Space in Digital Photo Professional.
If you are designing for the web exclusivelly, it’s best to work in sRGB. Learn how to set up Color Management for web design.
Oversaturated colors issue
Macs output colors in Apple RGB, so if a monitor can handle it, it will display colors more vivid, and somewhat truer to the real colors.
Apple is shipping displays that are not wide-gamut, but probably Apple RGB (at the time of this writing I haven’t found exact technical specs).
Apple displays are calibrated to Apple RGB and for the average PC user the picture is rich in colors. Apple’s products are also evenly calibrated to keep consistent experience across platforms, but that also gives you troubles once you pair Apple product with something else.
Dell U2711 is wide-gamut monitor, which means out-of-the-box colors will look too saturated than you probably used to using your laptop’s display or regular (lower-gammut) LCDs.
The display has quite a lot OSD controls, which was in my case miss-leading. There’s an option to set gamma for PC or Mac and also some handy color-space presets.
In Snow Leopard, default gamma is 2.2 (like the rest of the World) and not 1.8 like in Leopard (read how to make your display’s gamma in Leopard match Snow Leopard).
Setting gamma to Mac will create over-saturated picture and if you try different OSD presets, you’ll probably notice that nothing changes, even though you are switching between sRGB and Adobe RGB which are significantly different.
To make Dell U2711 display proper sRGB colors, set gamma back to PC and choose sRGB from the presets menu. This gives you the most accurate colors for web design and general use via built-in OSD.
At this point you might want to calibrate with OS X calibration software under System Preferences – Displays – Color – Calibrate. In my case Dell’s default .icc profile was a little greenish (Dell’s profile was already in there when MacBook Pro detected new display).
I was not happy with the results, so I calibrated mine using Spyder3Pro. Download .icc profile and see if this suits your particular display.
The created profile is more or less accurate. Spyder3Pro is a calibration tool for photographers and from what I learned on the internet forums not very accurate with spot colors, so I’m interested to give ColorMunki Design a try sometimes in the future, just to make sure this is true (Belgian graphic/web designer Veerle Pieters wrote a ColorMunki review back in 2009.).
Connectivity
I’m still working on a MacBook Pro with DVI port, so it was a breeze for me to connect the display with included Dual-Link DVI cable.
Newer Apple laptops are shipped with Mini DisplayPort, which leaves you with either Mini DisplayPort to Dual-Link DVI adapter or Mini DisplayPort to DisplayPort cable (both Dual-Link DVI and DisplayPort cables are included with the monitor).
However, I didn’t try any of these, so I suggest you investigate more about Dell U2711 + MacBook Mini DisplayPort.
The former is available in Apple Store, but costs $99 or $75 in OWC, and the later is $25 in OWC store (I’m not affiliated with OWC, but they ship items almost anywhere in the World).
Obviously, cable is a better option than adapters, but it might not suit your particular setup.
