Description

Overview

The HP ProOne 400 G3 is a 20-inch all-in-one business PC that puts the whole computer behind the screen. There is no tower under the desk and no tangle of cables — the processor, memory, storage and speakers all sit inside a single unit on an adjustable-height stand. For a shop counter, a reception desk or a small office, that matters: the machine takes up the space of one monitor and leaves the rest of the desk free.

This is the touch configuration: a 20-inch 10-point capacitive touchscreen at 1600 × 900 (HD+), so staff can tap a billing screen, swipe through a catalogue or sign a form instead of reaching for the mouse. One honest note: touch was an optional configuration across this family, and touch and non-touch units look identical from the outside — confirm with NexGenShop.pk that the stocked unit is the touch variant before ordering. Inside is an Intel Core i5-6500T, a 6th-generation quad-core processor drawing only 35 watts, with 8 GB of DDR4 memory, a 256 GB SSD, Windows 10 Pro, a 720p webcam and a SuperMulti DVD drive. The unit weighs about 5.6 kg without the stand and measures 497.7 × 347 × 58 mm.

Key Benefits

On a reception desk or a shop counter, touch is faster than a mouse for the jobs that repeat all day: opening a bill, selecting an item, checking a patient in. The 10-point panel responds to taps and swipes like a phone screen, and at 20 inches everything on it is within easy reach.

A traditional desktop needs a tower, a monitor and the cables between them. The ProOne 400 G3 needs one power cord and one desk space, and cables route through the stand so the desk stays tidy.

It is built for business peripherals: a serial + PS/2 combo port and two PS/2 ports on the back for receipt printers, barcode scanners and card machines, alongside six USB ports and a DisplayPort output for a second screen. Nothing needs an adapter to work.

The 35-watt processor sips power and stays quiet, so the machine can run all day without heating the room or the electricity bill.

Features and Advantages

The 20-inch TN panel is WLED-backlit at 1600 × 900 (HD+), with a capacitive layer supporting ten simultaneous touch points. The edge-to-edge glass front looks clean and modern on a counter.

The i5-6500T is a quad-core chip — four cores at 2.5 GHz, boosting to 3.1 GHz, with 6 MB of cache — on Intel’s H270 chipset with HD Graphics 530 built in, handling office work, browsing and video without complaint. The 8 GB of DDR4-2400 arrives as a single module in one of two SODIMM slots, so adding a second module to reach 16 GB is a five-minute job, and the 256 GB SSD boots the machine in seconds.

The side carries two USB 3.1 Gen 1 ports (one charging), a headphone and microphone combo jack and an optional SD card reader. The rear has Gigabit Ethernet, two USB 2.0 ports, two more USB 3.1 charging ports, a DisplayPort 1.2 output and the serial and PS/2 ports, plus dual-band 802.11ac Wi-Fi. The 720p webcam and dual-array microphone cover video calls, and the SuperMulti DVD drive still matters for businesses keeping records on disc. The box includes the stand, an HP USB Business Slim keyboard, an HP USB optical mouse and the power cord.

For the network behind it, a wall-plate access point such as the TP-Link EAP225-Wall or the Wi-Fi 6 TP-Link EAP655-Wall gives the room strong Wi-Fi, and a small-business gateway like the TP-Link ER605 router handles the internet connection and any branch-office VPN.

Ideal Users

Small shops will get the most from it. On a billing counter the touchscreen turns the computer into something the cashier taps rather than operates — faster at the till, easier to train new staff on — and the serial and PS/2 ports keep the existing receipt printer and barcode scanner working.

Reception desks and clinics suit it too: touch check-in, appointment lookups and visitor registration without a keyboard in the way, with the webcam for video calls. It also suits small offices and schools as a shared machine.

FAQs

Is the screen really a touchscreen? Yes — this is the touch configuration: a 20-inch 10-point capacitive panel at 1600 × 900. Touch was optional across this family, so confirm the stocked unit is the touch variant with NexGenShop.pk before ordering.

Which processor is in it? Intel Core i5-6500T, 6th Gen, four cores, 2.5 GHz up to 3.1 GHz. That is the 6th-generation i5 option for this model; the only other 6th-gen i5 offered in it was the i5-6600T.

Can it run Windows 11? No — not officially. 6th-generation Intel processors do not meet Microsoft’s Windows 11 requirement. This machine runs Windows 10 Pro.

Can I add a second monitor? Yes — a DisplayPort 1.2 output on the back connects an external display, so the machine can drive a second screen alongside its own panel.

What does “20:LCD” in the sheet title mean? It means a 20-inch LCD display — the panel is a 20-inch TN LCD at 1600 × 900.
