Monitor Dell UltraSharp de 27 inch Ultra HD 5k with PremierColor UP2715K

The Monitor Dell UltraSharp de 27 inch Ultra HD 5k with PremierColor UP2715K It is known as “the first monitor with ultra definition of the world 5k”. Are 5.120 x 2.880 pixels, a total of more than 14 million pixels. In addition it has the PremierColor, which provides excellent color accuracy, 99% de cobertura de AdobeRGB e 100% sRGB coverage. The Dell UP2715K It was acquired in my work, and it is with him I'm working on for about a week. I will not try to make a review here, because there are already several made by experts. I'll just leave my impressions.

It was my first contact with a resolution so high. I do not have TV 4K, I still think they are very expensive and little content is available. We pretty much just Netflix content to 4K, but to use it you need an Internet connection of at least 25 Mbps, which is something I have not. But if the story is different monitors. If the entertainment at 4K / 5K is not widely available, working with 4K / 5K is already possible. O Windows 10 It is ready to enlarge the text size, windows and other items, so that the resolution is immediately perceived 5K, because virtually all the expansion is done in level vector. Text and vector graphics are perfect.

The pixel density is so high that you can get within 10 cm from the monitor without being able to see a single individual pixel. I had only seen it on the iPad, from the third generation with Retina Display, which is the name that Apple chose to screens with high pixel density. In the case of the iPad are 264 dpi. The Dell UP2715K has 218 dpi, the same pixel density iMac with Retina Display 5K. I came to think that it would make sense a resolution so high on a 27 screen″, but does. Can not make a difference in TVs, where normally stay away from the screen, but not if monitors, we work within 1 metro da tela, It makes a nice difference.

To get an idea, mine Digital Camera Canon PowerShot SX60 HS strip photos 16 megapixels, 4608 x 3456 pixels, which means that you can see almost the entire photo on the screen without resizing. For photo editing, graphic works, etc. is excellent. Even for word processing and surfing the Internet at high pixel density makes it more enjoyable and natural.

The Dell UP2715K It has rigid screen and finished more glossy, unlike the monitor that I previously used, at Dell U2410 where the screen is flexible and matte. Both use IPS panel. The Dell UP2715K It has anti-reflective treatment, but you can still see some reflection when the image is very dark. But nothing too worrying, unless you work with a window right behind you or something.

O Windows 10 resizes automatically to almost everything 200%. This value is configurable to the user's taste. Using the setting in 200% the size of items on the screen as it is on a screen 2560 x 1440 pixels, but with the advantage of high pixel density. Exceptions are related to the Windows UAC windows and the Command Prompt, appearing without being resized and are very small, but you can read without much effort. The vast majority of applications have also automatically resizes. Virtually every tool I use to work respects the resizing and is perfect. It also includes common applications like Office, Browsers, Skype, Thunderbird, Tweetdeck, Spotify, among others, all perfect. Exception is mIRC, We need to have the increased supply manually. Adobe software, como o Photoshop, also do automatic resizing in newer versions (DC on), but in older (CS5, for example) the icons and some windows are very small, hindering the work.

A not very common requirement to use Dell UP2715K It is to have at least two DisplayPort outputs on the graphics card, because a single DisplayPort cable 1.2 can not transmit all 5.120 x 2.880 pixels, It is limited to 4K resolution (4.096 x 2.160). At the micro where the Dell UP2715K has been installed have a Placa de Vídeo Gigabyte GeForce GTX 970 (GV-N970G1 GAMING-4GD) with 3 DisplayPort ports, because we work with programming in CUDA possibly, then it does the job. Of course for those who want to use the games Dell UP2715K it takes more processing power, I would even say that Quad SLI is no exaggeration in this case. But how do I use only professionally and with predominantly 2D graphics, a GTX 970 that is enough.

By connecting both the DisplayPort GTX 970 on the Dell UP2715K, he has started to work immediately 5.120 x 2.880 pixels. I had no problems even in viewing the boot screen and BIOS settings. This problem is reported by some users and the crude solution from Dell is recommend having a second monitor just to make settings. Fortunately I will not have to go through it.

One problem I have been facing is that I left Dell U2410 como segundo monitor, connected in the third of DisplayPort Gigabyte GeForce GTX 970. But, when the display come into stand by, only Dell UP2715K Returns. The Dell U2410 remains stand by and the only way to wake it is disconnecting and reconnecting the DisplayPort cable. How it always worked perfectly before Dell UP2715K, rule out problems with the monitor or cable. I think it's something with the board or with the drivers for NVidia. But I'm using the latest version of drivers and already updated the BIOS. For now it is an unsolved problem.

O aspecto do Dell UP2715K it is 16:9, while the Dell U2410 it is 16:10, because it works with 1920 x 1200. Actually I always thought 16:9 It is best for TVs, and monitors benefit from the extra time provided by 16:10. But in moving to 4K / 5K appearance 16:10 It appears to have been left behind by the manufacturers. As the resolution is much larger and also have 3 inches more total size, I'm not missing the 16:10.

The Dell UP2715K also features a USB hub 3.0, It is an input port and 4 outlet ports, All the back. At this point the Dell U2410 It takes certain advantage, because two of the four USB ports are on the side. But we must consider that the Dell U2410 It is much thicker and ports are USB only 2.0. The Dell UP2715K It is more thin, and on the side just fitted the SD card reader, which is very practical.

I can say that I am quite satisfied with the Dell UP2715K. The only downside is not being able to have one of these at home. 🙂 Em casa tenho também um Dell U2410, that until then seemed perfect. But, after working with the Dell UP2715K, when I work from home and realize the difference of working with “only” 1920 x 1200 in 24 inches. Will look forward to the day when prices become more affordable and I can have a Dell UP2715K at home too.
