Bests & Worsts Reviews from Amazon

I have U3415W and U3417W in a dual-monitor setup, so I'm just going to comment on the differences. The two main differences are: - Less backlight bleed on U3417W. Most noticeable in a dark room viewing dark content. U3415W is not the best choice for watching movies full-screen. - Greater curve on U3417W. U3415W is slightly too flat for a monitor of this width. This matters mostly in a multi-monitor setup, where you might not always be sitting right in front of the monitor. As a single monitor, U3415W is fine. Both differences make U3417W better. Not worth the current 50% price premium, but clearly better. There are other, smaller differences: - Thinner bezel on U3417W. Approximately 10mm on U3417W and 13mm on U3415W. - U3417W has two USB ports on the side and two on the bottom. U3415W has one on the back and three on the bottom. Needless to say, both monitors are great. No discernible difference in picture quality.
