Ideal for image editing (Adobe color space, 2560x1440 resolution). Latest LED technology (GB-R). Viewpoint Stable (AH-IPS). Less for gamers. Cable included. Beautiful design. Anti-reflective. Gruesome On Screen Menu. Revision "A07" tested. No "squeaking" or similar noise.
Now in detail:
Resolution and size: the next generation screen (4k) just around the corner. We expect the resolution 3840x2160 display (compared to this monitor with "only" 2560x1440). It is better to wait?
I decided against it. Because resolution is not everything. Windows 8 comes up not really well with high resolutions. You can switch to larger view, large parts of the system, but the system does not scale automatically all the dialogs, which are issued by applications. As a result, one has suddenly tiny, barely legible window on the screen. The larger the monitor, the less the problem (assuming equal screen resolution).
For me here is 27 "in the" smaller "of the resolution sweet spot, where everything is still clean readable.
And one more request: The monitor requires a set 2560x1440 resolution. Please, please - make the windows in a same way. If the font is too small, rather scale the screen dialog to "150% size", set as a different resolution!
Viewpoint: It seems logical: The larger the monitor, the more areas we see not directly head-on, but with a slight angle. Old technologies showed color and brightness shifts here. For imaging a total "Nogo". The IPS Technolgy has not the problem. But it has the reputation of being a bit slower. Hardcore gamers should accurately inform (I recommend prad.de) and possibly for cheaper "hm" model grab.
Color Space: Our cameras are getting better. This monitor reproduces the Adobe RGB color space. Who uses a DSLR reasonably seriously, should be able to look at this color space. In practice, this means that more or less shades are distinguishable, as when "sRGB" color space.
Calibration: The monitor comes with a calibration protocol. Much readjustment was not necessary. I asked him a bit warmer (which allows the on screen menu via the color temperature) - if you have settled down in the grisly menu - I recommend the software from Dell to install from the CD - then you live pain free.
Backlight: Here is the latest UK R Techno Lige is used: very early compact fluorescent tubes (CCFL) were used. Problem: The monitor must be something "preheating" until it reaches the operating data (color fidelity ...). LEDs do not have the problem. Use the cheaper models as yet "white" LEDs. These are blue LEDs with a yellow phosphor converter. A very convenient method, which does not exhibit the problem of "lead time" in contrast to the CCFLs. However, here is the larger color space probably very difficult and the yield lower.
Ideal would RGB LEDs that emit all primary colors separately. This is rarely used for cost reasons. The newest "hot shit" the "GB-R" LEDs .. are you working with green and blue as a primary color and a "to red" phosphor converter. "Red" is therefore created as a waste product by increasing the wavelength of the green or blue light. This is currently the best technical affordable solution.
Flicker: LCDs do not flicker. Sensitive people sometimes complain about it to see the timing of the backlight (I do not belong). DELL clocks the LEDs (depending on the setting of brightness) for the most part not at all (see test at prad.de) - only below 50% brightness is pulsed at about 1000 Hz - which sees no more (cheaper monitors taken for reasons of cost with the 100Hz - the you can partially see).
Cable and little problems: As of this resolution, the graphics card and the cable "Dual Link" should be capable of. Grakas can actually been around for a very long time - the cables I have only fallen on the nose. My old wiring, it could not and the picture was completely broken and let himself not even with the right resolution set. Caution: Cheap cables and extensions can very listless disasters create - using the supplied cable! If the image "wedged" is totally wild or "pixels storms" emerge (who sees it will recognize) - always think of the cable.
The Image:
Lighting and colors are just great. My old "Refernz" HP is a little embarrassed in the corner ...
And I am very picky when working with Lightroom and Photoshop.
Power consumption: The above 24 "HP radiates considerably more heat towards the front, as this DELL The manufacturer max 130W, but that is extremely dependent on the set brightness is why I consider the.." Heat test "for quite informative.
Mechanics and Optics: The device looks very good! The height is adjustable very clean - all in all a great device for the (upscale) price.
Connections: A lot. DisplayPort, DVI, HDMI (no cable included) and USB.
The device contains no speakers.
Audit: There was probably some problems with the previous revision. This monitor in front of me, the revision "A07" - that is probably the latest (you can see on the box behind the product number there is a field "Revision"). Others had probably (especially with older Revsionen) problems with "tweeting" on the monitor. This is mostly due to sloppiness in the power supplies (loose coil or similar) - I have no problems.
In conclusion: I recommend him further - for people who are serious about image editing operate for most others it would be overkill.
PS: the writing of this review took more than an hour. It was important for me to type up any specifications, but represent what motivated me to choose this monitor and if the bill came up. Should I forget something, I am pleased with corrections in the comments or by email. "Helpful" ratings are the spur, not tumb squatting front of the TV, but here provide information for others. So it would be nice .... ;-)
