31.5-inch 4K VA panel for colour-critical work
The Philips 32B1U3900 delivers a 31.5 inch viewable area at 3840 by 2160 resolution on a VA panel with 3500:1 static contrast. It covers sRGB 122% and NTSC 106% with 1.07 billion colours at 350 nits brightness, making it suitable for creative professionals and office users who need accurate colour reproduction.
Flat anti-glare screen
The flat panel uses an anti-glare coating with 3H hardness and 25% haze to reduce reflections. The stand provides 180 mm height adjustment, -5 to 25 degree tilt, +/-180 degree swivel and +/-90 degree pivot for flexible positioning. A single USB-C upstream port carries DisplayPort Alternate Mode video and up to 90 W power delivery while feeding four downstream USB-A ports, one supporting BC 1.2 fast charging, plus an integrated RJ45 Ethernet connection.
60 Hz ceiling and HDMI 2.0 bandwidth limit
The monitor accepts 4K signals at 60 Hz through DisplayPort 1.4, USB-C DP Alternate Mode or two HDMI 2.0 ports. HDMI 2.0 caps 4K at 60 Hz without HDR metadata support, so higher refresh rates or 10-bit HDR at full resolution are not possible. The 4 ms gray-to-gray response suits general productivity but may show motion blur in fast-paced gaming. VESA 100 x 100 mm mounting is available for arm or wall installation.

商品問答
Does the USB-C port with DP Alt Mode deliver 90 W charging while driving 4K at 60 Hz?
Yes, the single USB-C upstream port supports DisplayPort Alternate Mode and provides up to 90 W power delivery alongside 3840 x 2160 at 60 Hz.
What VESA pattern and stand clearance does the 31.5" chassis require?
The monitor uses a 100 x 100 mm VESA mount; the stand offers 180 mm height travel, -5 to 25° tilt, ±180° swivel and ±90° pivot.
How do you enable the integrated RJ45 Ethernet through the USB-C link, and what common step is missed?
Connect the USB-C cable to a host that supports DP Alt Mode and USB data; the hub then exposes the RJ45 port — the step often missed is ensuring the host USB-C port carries both video and data, not just power.
