The HP Series 3 Pro 21.5 inch FHD Monitor (model 322ph) is a professional display designed for business environments. It features a screen diagonal of 54.6 cm (21.5 inches) and provides a native resolution of 1920 x 1080 pixels, matching the Full-HD standard. The display technology is based on an IPS panel with LED backlighting, ensuring uniform brightness distribution and high color accuracy. The display surface is matte, reducing reflections and glare, making the screen suitable for use in office environments with varying lighting conditions.

Applications
This monitor is designed for use in offices, workstations, and other professional environments where clear, color-accurate display and high readability of text and graphics are required. The 16:9 aspect ratio and Full-HD resolution are particularly suitable for displaying documents, spreadsheets, presentations, and multiple windows simultaneously. Integrated speakers with an RMS power of 4 W enable simple audio playback without additional speaker systems.

Features and Specifications in Detail
The screen offers a brightness of 250 cd/m², ensuring good visibility even in daylight. The contrast ratio is 1000:1 (typical), enabling clear visibility of depth and detail in images. The response time of 5 ms (Gray to Gray) ensures smooth motion display and avoids visible distortions during fast image changes. The maximum refresh rate is 100 Hz, providing flicker-free display. Viewing angles are 178° horizontally and vertically, allowing good visibility from various positions. The color depth is 8 bit, and the color gamut covers 72 % of the NTSC color space, ensuring natural color reproduction.

Technology Explained Simply
The IPS panel (In-Plane Switching) ensures uniform color and brightness distribution across the entire screen, even at viewing angles up to 178°. The LED backlighting with side-LED technology guarantees homogeneous brightness without visible hotspots. Flicker-free technology and Low-Blue-Light technology reduce eye strain during prolonged use. The matte coating minimizes reflections, which is especially beneficial in offices with windows or artificial lighting.

Compatibility and Accessories
The monitor features an HDMI port (version 1.4), a DisplayPort (version 1.2), and a VGA port (D-Sub), ensuring compatibility with a wide range of graphics cards and computers. HDCP support enables playback of protected content. The VESA mounting interface with a mounting pattern of 100 x 100 mm allows installation on wall mounts or monitor stands. The integrated cable lock slot provides additional theft protection.

Mounting and Installation
The monitor comes with a removable stand that allows height adjustment up to 10 cm and tilt adjustment from -5° to +23°. These adjustments support an ergonomic working position. The On-Screen Display (OSD) enables direct adjustment of screen parameters on the device.

Operational Advantages
The monitor is characterized by high image quality, excellent color reproduction, and ergonomic design. Integrated speakers and multiple connectivity options reduce the need for additional devices. The energy efficiency class D (SDR and HDR) and power consumption of 18 W in standard operation make the monitor an energy-efficient solution. The operating temperature range of 5 to 35 °C and storage temperature range of -40 to 65 °C demonstrate the device’s robustness under various environmental conditions.

Product Type, Core Function, Technology, Standard
The monitor is an LCD display with IPS panel technology, designed for business use. The Full-HD resolution and matte surface are key features. The VESA mounting and height adjustment support ergonomic use. The energy efficiency class D is specified according to EU standards.
