To set up a mini PC, connect the monitor, keyboard and mouse, attach the supplied power adapter, then turn it on and complete the startup prompts.

Start with one screen and the fewest accessories you need. Once the desktop works, add a second display, printer or other equipment so you can spot the cause if something stops working.

What do you need to set up a mini PC?

You need a display, input devices and the right cables, plus the computer's power adapter. You can reuse a monitor, keyboard and mouse if their connections match.

Before buying anything, check:

• Video ports: the computer needs an output that matches your monitor's input.
• USB ports: leave room for a keyboard receiver, webcam or external drive.
• Operating system: confirm whether one is included and ready to configure.
• Network: have your Wi-Fi password or an Ethernet cable ready.
• Desk space: allow room for vents, cable bends and access to the power button.

Don't assume a USB-C port carries video or accepts power. Those functions depend on the computer, so check its manual before planning a one-cable setup.

If you're still choosing the computer, our mini PC buyer's guide helps you compare options before you buy accessories.

Which equipment suits a basic mini PC desk?

The equipment below suits everyday desk work, but you only need the pieces you don't already have. Check the included cables first: both the GMKtec computer and Philips monitor include an HDMI cable.

GMKtec G3S: for browsing and routine office work

The G3S pairs an Intel N95 processor with 8GB of DDR4 memory and a 256GB SSD. It's a sensible starting point for documents, email, streaming and a modest number of browser tabs.

Choose it for a small home workstation with light workloads. Skip it if you expect heavy video editing, demanding games or many large apps running together; compare higher-performance computers instead.

Also consider storage before moving your files. A large photo or video collection can make a small system drive restrictive, even when the computer is powerful enough for your apps.

Philips 241V8LB: for a straightforward work screen

The Philips has a 23.8-inch VA panel with 1920 x 1080 resolution and a 100Hz refresh rate. It suits email, documents and general browsing without requiring a large desk.

Its EasyRead mode is useful to try for long documents. Adjust brightness to suit the room rather than leaving it at a setting that feels glaring.

Skip this screen if you need lots of room for large spreadsheets or fine detail from a higher-resolution display. Screen size and workspace matter more than refresh rate for those tasks.

Logitech MK270: for simple first-start input

The MK270 connects both devices through one USB-A receiver, avoiding Bluetooth pairing during startup. Its full-size keyboard includes a number pad, while the mouse has an ambidextrous shape.

Choose it for data entry and a conventional desk layout. Skip it if a full-size keyboard would crowd your mouse area or you want to keep every USB port free.

UGREEN HDMI cable: for a longer cable route

The UGREEN cable provides a 6.6-foot connection when the included cable won't reach your desk layout. Its braided jacket is another reason to consider it for a cable you move often.

Skip this extra if an included cable already reaches comfortably. Its higher bandwidth won't increase the Philips monitor's resolution or add display modes that your computer and screen don't support.

How do you connect a mini PC to a monitor?

Connect a matching video output and input, then select that input on the monitor. For the example equipment above, HDMI provides a direct connection without an adapter.

How to set up a mini PC with HDMI

With the devices off, insert the HDMI cable into the computer and monitor. Connect the monitor's power cord, then use its controls to select HDMI when you turn it on.

Leave enough cable slack to move the screen without pulling on either socket. Match the connector's shape and don't force it into place.

For a second screen, the G3S supports two displays through its HDMI outputs. Connect one first, finish setup, then add the other and choose Extend in display settings for separate work areas.

If you use an adapter with other equipment, check its direction. An adapter designed for one signal direction may not work when reversed.

How do you connect the keyboard and mouse?

Connect your input devices before the first startup so you can respond to setup prompts. Wired devices and USB receiver combos are the simplest options at this stage.

For the MK270, insert its receiver into a USB-A port, check the batteries and switch on both devices. Keep the receiver somewhere accessible until you know the keyboard and mouse respond.

Bluetooth keyboards need pairing through computer settings. If you can't reach those settings yet, use a wired keyboard or receiver-based device to finish setup.

If input stops working, check batteries and power switches before changing software settings. Try another USB port and move the receiver away from metal obstructions if the connection is unreliable.

How do you power on a mini PC for the first time?

Use the power adapter supplied for that computer, then press the power button. A connector that fits doesn't prove that a different adapter has the correct electrical output.

Turn on the monitor and wait for the startup screen. Avoid repeatedly switching off the computer while it is starting or completing an update.

If an operating system is installed, follow its language, region, keyboard and account prompts. A barebones computer or one without an operating system needs additional installation work before normal use.

Our guide to whether mini PCs come with Windows explains what to confirm before you reach this step. Don't assume the G3S configuration described here includes a particular Windows edition.

How do you finish the initial computer setup?

Connect to your network, install updates and check the desktop before adding extra software. This gives you a clear starting point if an accessory or app later causes trouble.

Use Wi-Fi for flexible placement or Ethernet when a router connection is within reach. For Wi-Fi, choose your own network carefully and enter its password.

After reaching the desktop:

1. Run the operating system's update tool and restart when requested.
2. Check display resolution, text size and available refresh-rate settings.
3. Confirm sound plays through your chosen output.
4. Check free storage before copying large folders.
5. Set up a backup for files you can't replace.

Get drivers from the computer maker's support service or the operating system's update tool. Avoid third-party driver bundles.

For a shared desk, create separate user accounts. Our mini PC home office guide covers other equipment choices for a regular workspace.

What should you check if the monitor stays blank?

Check monitor power and input selection first, then the cable and computer. A “no signal” message means the screen is on but isn't receiving a usable picture through the selected input.

Open the monitor's own menu. If that appears, reseat the video cable at both ends and confirm that the mini PC is powered on.

Try another compatible cable or video output, changing one thing at a time. Disconnect extra displays and adapters to simplify the connection.

If a startup logo appears but the desktop doesn't, check the computer's recovery or display support steps. That pattern calls for a different approach from a monitor that never receives a signal.

Should you mount a mini PC behind a monitor?

Mount it only after the desk setup works and you've confirmed the hardware fits. This saves you from removing the computer again to reach ports during initial setup.

The G3S includes a VESA mount with screws, and the Philips supports VESA mounting. Check the hole pattern, bracket arrangement and screw requirements rather than assuming the parts fit together.

A monitor arm may already occupy the mounting holes. Our guide to mounting a mini PC behind a monitor explains what to check before attaching the computer.

Keep vents open and leave access to the power button and cables.

How do you keep a mini PC cool and working?

Keep air paths clear and remove dust according to the computer's care instructions. Don't place the computer on soft fabric or stack objects against its vents.

Shut it down and unplug it before cleaning. Keep liquids away from openings, and avoid opening the case unless the maintenance instructions call for it.

Before moving the desk, disconnect cables rather than letting them pull against sockets. Keep the power adapter ventilated too.

If the computer slows down, crashes or shuts off, check airflow and software updates before buying replacement parts. Our guide to mini PC overheating and crashes covers the next checks.

How should you choose your mini PC setup?

For a basic mini PC setup, reuse compatible equipment first and buy only what fills a gap. The G3S suits routine work, the Philips suits a compact document desk, and the MK270 simplifies first-start input.

Add the UGREEN cable only when you need its reach. If your work calls for more memory, storage or screen space, choose those before spending on extra accessories.

Once you know how to set up a mini PC, the remaining decision is whether its size fits your workload. Read how mini PCs compare with desktops before committing to a computer for heavier work.

Frequently asked questions

What do I need to set up a mini PC?

You need the mini PC, its supplied power adapter, a monitor with a matching video input, a suitable cable, and a keyboard and mouse. Keep your network password nearby if you'll use Wi-Fi, and check which cables are included before buying extras.

Can I use a mini PC with any monitor?

You can use a monitor when its input matches the mini PC's video output, either directly or through a suitable adapter. Check the supported resolution and refresh rate too, because the computer, connection and monitor must all support the display mode you want.

How do I connect a wireless keyboard to a mini PC?

For a receiver-based keyboard, insert its USB receiver, fit the batteries and switch the keyboard on. Bluetooth keyboards need pairing through the computer's settings, so keep a wired or receiver-based keyboard available if you can't reach those settings during the first startup.

Why is my mini PC not showing on the monitor?

Start by checking monitor power, the selected input and the video cable at both ends. If the monitor shows its own menu but no computer picture, try another compatible cable or output, then follow the computer's support instructions if the screen stays blank.
