Can You Add a Second Monitor to an All-in-One PC? Dual Screen AIO Setup Guide

30 Oct 2026

One of the most common questions about all-in-one computers is: can you add a second monitor to an all-in-one PC? With the right model, yes – and a dual-screen AIO is one of the most productive desk setups you can buy.

What you need

  • An all-in-one PC with a video output – DisplayPort or HDMI out.
  • A monitor with a matching input.
  • The right cable (DP to DP, HDMI to HDMI, or an adapter).

Hibertek all-in-ones with display outputs

The Thin Mini-ITX models GI24, GI27, U24 and BG24 include both DisplayPort and HDMI out on the rear I/O (depending on motherboard configuration), and an optional extra I/O kit can add a further HDMI out. That makes extended desktops straightforward.

Step by step

  1. Connect the monitor to the AIO’s DisplayPort or HDMI out.
  2. In Windows 11, open Settings > System > Display.
  3. Choose Extend these displays.
  4. Drag the screens to match their physical layout.

Best pairings

  • Finance and analysts: GI27 with QHD 2560 x 1440 plus a 24″ second screen.
  • General office: U24 plus a matching 24″ monitor on a VESA arm (the U24 supports VESA 100).
  • Design-led workspaces: BG24 with its aluminium Y stand.

Performance

Because these models take desktop processors up to 65W and up to 64GB of memory, driving two Full HD or QHD displays is comfortable for office and productivity work.
