Dell U2917W and U3417W UltraWide monitors

Since the introduction of the first 21:9 monitors, including the Dell U2913WM, there have been many developments in this sector. Larger screens, the introduction of various levels of curvature and higher resolutions and refresh rates. Dell have now refreshed their UltraWide line-up with replacements for both the U2913WM and U3415W. The U2917W is a replacement for the former, again featuring a flat 29” screen with 1920 x 1080 resolution. The U3417W is a replacement for the latter, featuring a steeper curvature than last time owing to a new panel being used (1900R compared to 3800R – so ‘twice as curved’). Both models retain the smart, unfussy and professional look of their predecessors. Pressable buttons rather than any flashy or potentially temperamental touch-sensitive buttons are used for the OSD (On Screen Display) controls. The power light is a gentle cool white, nothing bright, colourful or flashy.

A 29” 2560 x 1080 panel is used on the U29 and a 34” 3440 x 1440 panel used on the U34, so both are 21:9 UltraWide parts with light (and ‘ungrainy’) matte screen surfaces. Both panels are LG AH-IPS, run at a native 60Hz refresh rate and feature the expected 178° horizontal and vertical viewing angles and 1000:1 specified static contrast. Flicker-free WLED backlights are employed, with a typical maximum luminance of 300 cd/m² and comprehensive sRGB coverage (at least 99% promised but some over-extension as well – these are standard gamut models). To further enhance viewing comfort, a new ‘ComfortView’ Low Blue Light setting is included. The 29” model is true 8-bit with a factory calibration touting a DeltaE <2. Meanwhile, the 34” model feautures 8-bit + 2-bit FRC dithering (10-bit effective) and a promised Delta E <3. A 5ms grey to grey response time is specified for the smaller model and 6ms is specified for the larger model. As usual Dell’s values are usually far more reflective or real-world performance than the highly optimistic values touted by other manufacturers, so take this with a dose of salt.

The stands offer tilt, height and swivel adjustment and are attached to the rear of the screen using a quick-release bracket mechanism. Once the stand is removed, 100 x 100mm VESA holes are found for alternative mounting. The ports on both models are; DP 1.2, mDP 1.2, DP 1.2 out (for MST ‘Daisy Chaining’), 2 HDMI 1.4 ports, 4 USB 3.0 ports (2 with DC 1.2 charging for connected devices) and a 3.5mm headphone jack. 2 x 9W speakers are included on the 34” model, too.

Further information on the 29” model (Chinese, translation required) and 34” model can be found on various regional Dell websites. The 34” model can be found for around $1000 in the US. Further pricing details to be confirmed. Provided there’s sufficient interest we will consider reviewing at least one of these models.
