The Dell UltraSharp U3417W is an excellent monitor if you are looking for colour fidelity in a uwqhd-monitor. As we have come to expect, the construction of the monitor is solid and it has excellent connectivity. The test results are, especially in terms of the colour quality, very good. If you value accurate reproduction, the uniformity compensation is a useful function.
However, that functionality does come with a severe downside: the contrast is not impressive when it is turned on. Furthermore the black value disappoints as well, something we often see with calibrated monitors based on ips-technique. This makes the monitor less attractive for watching video and we would not recommend it for gaming either – the limited functionality for that purpose and the modest response time are reason enough to look elsewhere.
In our opinion this results in a rather small target audience for the U3417W: web designers, graphic artists and video editors will all approve of the extremely good colour quality and the MSRP is not that bad for this target audience either. Of course the colour range of this monitor is limited to sRGB/Rec.709, but especially for web content this is sufficient.
For all other target audiences there is presumably another monitor that suits the specific needs better. If you simply want a lot of (horizontal) work space as cheap as possible, you can find considerably less expensive uwqhd-models like the Iiyama Prolite XUB3490WQSU-B1 (not curved, but also about 268 pounds / 300 euros cheaper). If you do want a curved panel you have a lot of options for productivity applications, of which the still readily available predecessor U3415W is definitely worth considering. The LG 34UC88 is also a lot less expensive, while the 34UC98 might come closer to the U3417W in terms of price but also offers Thunderbolt-connectors. Last but not least, gamers are better off looking at a slightly more expensive model with 100Hz panel and G-sync such as the Asus PG348Q or the Acer X34 (although the latter is not readily available), or the Asus MX34VQ, that we will cover in more detail soon.
