Philips 27B1U3900 27" 4K UHD IPS Business Monitor – USB-C 90W PD, RJ45, USB Hub, HDR10, HDMI 2.0, DP 1.4 & Ergonomic Stand

The Philips 27B1U3900 is a 27-inch business/productivity monitor built around a 4K UHD IPS panel and integrated USB-C docking. Its strongest selling point is the ability to connect a compatible laptop through one USB-C cable for video, data, networking/peripherals, and up to 90W Power Delivery. 

Core display specifications

Philips specifically positions the UltraClear 4K resolution for detailed professional work such as large spreadsheets, graphics and other productivity applications.

USB-C docking

This is the standout feature of the 27B1U3900.

USB-C supports:

• DisplayPort Alt Mode
• High-resolution video
• Data transfer
• Up to 90W Power Delivery
• USB PD 3.0
• Connection to the monitor's integrated USB hub

This means a compatible notebook can use a single USB-C connection for the display, peripherals and charging. 

Connectivity

The monitor is particularly well equipped for a professional workstation:

• 2 × HDMI 2.0
• 1 × DisplayPort 1.4
• 1 × USB-C upstream
• 3 × USB-A downstream
• 1 × USB-A with BC 1.2 fast charging
• RJ45 Gigabit Ethernet
• Audio out
• USB 3.2 Gen 1 hub — 5Gbps
• HBR3 support

The RJ45 connection can provide up to Gigabit Ethernet when operating through the appropriate USB connection. 

Built-in audio

2 × 2W stereo speakers are integrated into the monitor, reducing the need for basic external desktop speakers. 

Ergonomic stand

The SmartErgoBase offers significantly more adjustment than a basic monitor stand:

• Height: 130 mm
• Tilt: -5° to +25°
• Swivel: ±180°
• Pivot: ±90°
• VESA: 100 × 100 mm

The 90-degree pivot capability is particularly useful for coding, documents and vertically oriented content.
