How to Use a Laptop as a Monitor: Complete 2026 Guide

Need an extra screen but don't want to spend hundreds on a new monitor? With 76% of remote workers using multiple displays for productivity, the demand for affordable screen solutions has never been higher. The good news: you can use a laptop as a monitor for your desktop PC, gaming console, or another laptop using several proven methods.

Whether you want to use laptop screen as external monitor for Xbox gaming, create a dual-screen setup with an old laptop, or extend your desktop workspace, this comprehensive guide covers all methods—from wireless display to HDMI capture cards. Let's explore how to transform your laptop into a functional secondary display.

The short answer is yes, but with important limitations. Unlike traditional monitors, laptop screens aren't designed to accept video input directly. Here's why:

Critical Fact: 99% of laptop HDMI ports are output-only, meaning they send video signals OUT to external displays but cannot receive signals IN from other devices.

Why This Matters:

• You cannot simply connect an HDMI cable from your Xbox to your laptop and expect it to work
• Laptop displays use internal connections (LVDS, eDP) that are incompatible with standard HDMI input
• Special hardware or software solutions are required to make your laptop function as a monitor
• Available Methods to Use Laptop as Monitor

Fortunately, there are three proven approaches:

• Wireless Display (Software): Use built-in Windows features or third-party apps
• HDMI Capture Card (Hardware): Convert external video signals into USB data your laptop can process
• Hybrid Solutions: Combine software and minimal hardware for specific use cases

Each method has different performance characteristics, costs, and ideal use cases—which we'll explore in detail below.

The easiest way to use laptop as second monitor is through Windows' built-in wireless display feature called "Projecting to this PC". This method is completely free and requires no additional hardware.

Requirements for Wireless Display

• Both devices running Windows 10/11
• Both connected to the same WiFi network
• Miracast support (most laptops from 2015+ have this)
• No special cables or hardware needed

1. Open Settings (Windows Key + I)
2. Navigate to System > Projecting to this PC
3. Change the first dropdown to "Available everywhere" or "Available everywhere on secure networks"
4. Set "Ask to project to this PC" to "Every time a connection is requested" (⚠recommended for security)

Optional: Set "Require PIN for pairing" for added security

1. Press Windows Key + K to open the Connect sidebar
2. Click "Connect to a wireless display"
3. Select your secondary laptop from the list
4. Accept the connection request on the secondary laptop
5. Choose display mode: Duplicate or Extend
