Dell UltraSharp U3417W review: update of a favorite

Extremely good colour quality with clear downsides


Gaming: response time and input lag

The Dell UltraSharp U3417W is not a gaming monitor. It has a standard 60Hz refresh rate and does not support things such as G-sync or Freesync. For this reason we only show a selection of the results, the added values of rise and fall in standard-mode and with maximum overdrive and with the setting that is optimal for gaming in our opinion. Sub values can be found on the product page of the monitor, in the Test Results tab.

Out-of-the-box the U3417W does not turn out to be a fast monitor. Remarkably enough the 0%-100%-0% transition is slower than the predecessor U3415W, the 20%-80%-20% is faster. With overdrive on maximum the monitor is faster, although still not great, but we do measure a rather high overshoot of 52%. Back to the ‘Normal’ setting, where we end up at 19.9 ms for a double transition white-black-white. Fortunately the rise- and fall-times are evenly distributed, so with 11.7 ms for the longest transition 60 fps is still a possibility.

Input lag

The Leo Bodnar input lag tester did not yield any usable results with the U3417W – as we see more often, there were no reproducible values. At least the comparison with a CRT-monitor does not show any noteworthy input lag.
