Dough, an up-and-coming display brand that previously unveiled the cord-free NANO 2K Monitor has now unveiled a new 4K monitor for the global market called the Spectrum Black 4K ES07E3D. The Spectrum Black 4K ES07E3D monitor features a 31.5-inch diagonal display with a 16:9 aspect ratio. The monitor utilizes an OLED panel that achieves a peak brightness of 1000 nits with HDR (400 nits for full-screen content). It provides complete coverage of the sRGB colour gamut (100%) and an impressive 98.5% coverage of the DCI-P3 gamut. The monitor boasts a contrast ratio of 1,500,000:1 and maintains a typical Delta-E of less than 1 for accurate colour representation.The ES07E3D model incorporates a Gorilla Glass cover with a DXC anti-glare coating. As stated by Dough, this combination results in a glare reduction of up to 70% when compared to their glossy monitor counterparts. Additionally, the Spectrum Black 4K ES07E3F is an alternative matte option if you want a matte display.
The Dough Spectrum Black offers two different surfaces: a low-haze, anti-glare matte coating (ES07E3F) and a more premium Corning Gorilla Glass 3 offering (ES07E3D), with DXC anti-reflective treatment coating that allows for “best-in-class optical performance and industry-leading abrasion resistance” as per Dough. Connectivity options encompass 2 HDMI 2.1a ports, 1 DisplayPort, 2 USB-C inputs (one offering DisplayPort 1.4 and up to 100 Watts power output, the other for upstream connection), along with 2 USB-C outputs and 2 USB-A outputs (both supporting up to 5 Watts power). A 3.5 mm audio jack is also included. It supports Nvidia G-Sync and AMD Free Sync technologies for enhanced graphics performance. Dough claims that these offer better ambient contrast ratios by 40% and lower reflections by 70% compared to their older “glossy” models.
