Product information

Description

The HP Series 3 Pro 21.45 inch FHD Monitor provides an extra 21.45 inches of workspace with a Full HD 1920 x 1080 resolution and a VA LCD panel. The matte screen reduces glare and the flat form factor fits typical desk setups; VESA mounting is supported for alternative placements. Designed for everyday productivity, it balances clear visuals with a simple, unobtrusive design.

Advantages

This monitor offers a sharp Full HD image, a wide 178° viewing angle and a 5 ms response time for smooth on-screen motion. High typical contrast (3000:1) and 250 cd/m² brightness deliver readable content in most indoor lighting conditions. Its lightweight, black chassis and VESA compatibility enable flexible installation.

Suitable for

Office work and productivity applications (documents, spreadsheets, email)
Web browsing, video streaming and general multimedia
Multi-monitor setups to expand desktop space
Home and small business workstations with limited space

When it may not be suitable

This monitor is not aimed at professional colour-critical workflows such as photo or video colour grading, where higher colour accuracy and wider colour gamut panels are required. It also lacks built-in speakers and a USB hub, so users needing integrated audio or multiple peripheral ports will require additional accessories.

How to use

Place the monitor on a stable desk or attach it to a compatible VESA mount.

Adjust tilt and display settings via the on-screen menu to set brightness, contrast and colour preferences for comfortable viewing. Position the screen at eye level and at a suitable viewing distance to reduce strain during extended use.

What to consider before purchase

Ensure your computer’s video output matches the monitor input or that you have the correct adapter.
Consider whether you need built-in speakers or additional USB ports, since this model lacks them.
Check VESA mount size and compatibility if you plan to wall- or arm-mount the display.
Assess whether Full HD resolution and a 21.45-inch screen meet your workspace and multitasking needs.

Usage recommendations

This HP Series 3 Pro monitor is best used as a secondary or primary display for everyday office tasks, web content and media consumption. For extended comfortable use, calibrate brightness and contrast to your environment and use an external audio solution if sound is required.
