Overview

A 39.7-inch curved 5K2K IPS monitor built for color-critical work and high-density multitasking. It suits creative professionals and power users who need expansive, accurate screen space.

Display Performance

The 2500R curved IPS panel delivers 5120 x 2160 resolution across a 21:9 aspect ratio. It covers 99% of DCI-P3 with 10-bit color depth and meets VESA DisplayHDR 600 at 450 nits typical brightness. A 120 Hz refresh rate and 5 ms gray-to-gray response support smooth motion, while FreeSync Premium reduces tearing.

Connectivity and Docking

One Thunderbolt 5 port, two HDMI 2.1 ports, and one DisplayPort 2.1 handle video input. The USB hub adds one USB4 Type-C, three USB 3.2 Type-C, two USB 3.2 Type-A, and a 2.5 GbE RJ-45 jack. The Thunderbolt 5 connection provides USB-C power delivery to charge a connected laptop.

Ergonomics and Build

The stand adjusts 130 mm in height, tilts from -5 to 20 degrees, and swivels ±20 degrees. A 100 x 100 mm VESA pattern allows arm or wall mounting. The monitor weighs 14.1 kg with the stand and 9.2 kg without it.

Audio and Extras

Integrated dual 10 W speakers provide stereo output without external hardware. A 3.5 mm TRRS jack supports headset use. The matte non-glare coating reduces reflections in bright environments.
