Purchased the monitor for business work. It is gorgeous. The resolution of the fonts is very clear, I am sure it has reduced my eye strain. It takes the place of two monitors and allows me to view two programs (browser, Word, Excel, etc.) at the same time without sacrifice of viewing space. Was not sure I would like a curved monitor. The curve actually helps. You can’t see all of the screen at once causing your peripheral vision to see the area you are not concentrating on. The 3800R seems to be a good curvature for this. I did not look at the Dell U3417W, so I do not know if the 1900R curvature of the U3417W would be better or worse, but my guess was that I would not have liked the tighter curvature of the U3417W as much as the U3415W. The biggest problem I had was with the included DisplayPort cable. I think Dell includes cheap cables. Using the included DisplayPort cable, I connected the monitor to a Microsoft Surface pro 4 and the monitor would go straight to sleep. After 5 hrs of getting nowhere with Dell support trying to determine the issue, I found some Internet dialog about using a better cable. Went and purchased a $15 cable advertised as being 4k/UHD and Microsoft Surface compatible and voila all of my issues were solved. I have used the monitor for about 1 month now and love it. Using it for work 8hrs/day – it was well worth the purchase.
I have placed a few of these in different offices and everyone loves them. Be aware that users take a week or so to adjust to the 'big' monitor, but productivity goes up significantly because they no longer have to open and close windows.. you can have everything up on your screen.. an entire huge spreadsheet.. your email, your calendar etc.. this beats having two monitors because in the middle it is bezelless.
