Large UltraWide monitors offer an immersive gaming and movie watching experience whilst providing an expansive workspace. The Dell U4021QW of the UltraSharp series offers a screen size of 39.7″ in the 21:9 UltraWide format. The styling is minimalistic, in keeping with other recent additions to the series. The top and side bezels are dual-stage with a slim panel border that’s flush with the rest of the screen, plus a thin hard plastic outer component. The OSD (On Screen Display) is controlled by a joystick at the rear of the monitor, towards the right side as viewed from the front.
A 39.7″ 5120 x 2160 (21:9 UltraWide) IPS panel is used, most likely the LG Display LM400RW1-SSA1 Nano IPS part. In terms of pixel density and vertical screen size, this is very much like a 31.5″ 3840 x 2160 (‘4K’ UHD) model – with extra horizontal pixels and screen space. A 60Hz refresh rate is offered, alongside a light matte anti-glare screen surface and 2500R (relatively gentle) curve. A 1000:1 static contrast ratio, 10-bit colour support and 178/178° viewing angles are specified whilst a flicker-free WLED backlight is employed. This offers a 300 cd/m² typical maximum luminance and 98% DCI-P3 colour space, with a factory calibrated sRGB emulation mode offering a claimed average DeltaE <2. Low Blue Light (LBL) settings are included to potentially enhance viewing comfort. A 5ms grey to grey response time is specified, but as usual don’t pay too much attention to this figure. The included stand attaches centrally using a quick-release mechanism – it offers tilt, height and swivel adjustment and can be replaced by an alternative 100 x 100mm VESA compatible solution. The ports face downwards and include; AC power input (internal power converter), 2 HDMI 2.0 ports, DP 1.4, a 3.5mm audio output, Thunderbolt 4 (USB-C 3.2 Gen2 with DP Alt Mode + 90W PD), 3 USB 3.2 Gen2 ports (plus upstream) and an RJ45 port. An additional USB 3.2 Gen2 port with BC 1.2 capability and USB-C downstream port (3.2 Gen2, 15W charging) is located at the very bottom of the screen, for easy access from the front. KVM capability is offered and 2 x 9W speakers are included for potentially rich and powerful sound output.
