There is also one 10 Gb/s USB-C 3.2 Gen 2 upstream port, two 10 Gb/s USB-C 3.2 Gen 2 downstream ports with 15W of charging power, five 10 Gb/s USB-A 3.2 Gen 2 ports, one of which supports device charging, and a 2.5 Gigabit Ethernet port for network connectivity. Audio from HDMI or DisplayPort sources may be output using the dual 9W speakers or 3.5mm output, which does not support headphones.
Also featured is an anti-glare panel with IPS Black technology, a 120 Hz refresh rate, support for 1.07 billion colors (8-bit + A-FRC), coverage for 100% of the sRGB, 100% of the Rec. 709, and 99% of the DCI-P3 and Display P3 color gamuts, a static contrast ratio of 2000:1, 600 nits peak brightness with VESA DisplayHDR 600, 450 nits of typical brightness, and 8 ms (normal) / 5 ms (fast) GtG response times. Using the 178° horizontal and vertical viewing angles, it is possible to watch content from virtually any position. To further help improve viewing and accessibility, the display features a vertical tilt of -5 to 21°, a swivel of 60° (±30°), and a 5.9" height adjustment. If you'd like to attach this display to a wall, there is an integrated 100 x 100mm VESA mount.
Please note that the USB-C 3.2 Gen 2 upstream port must be connected to your host system when the HDMI or DP ports are in use. It is to enable USB communication between the monitor downstream devices and the host.
