Mac as a Second Monitor for PC: The Complete Guide

In the era of remote work and multitasking, having more screen space is no longer a luxury it's a productivity powerhouse. If you've ever asked, "Can I use my Mac as a second monitor for my PC?" the answer is yes. And it’s easier than you might expect.

Whether you're dusting off an old MacBook or repurposing your iMac, turning your Mac into a second display can save you money and optimize your workspace. As someone who manages multiple projects daily, I’ve experienced firsthand how this setup can transform your workflow.

Method 2: Wired Connection (HDMI/Adapter Solutions)

Prefer a physical connection? While most Macs don’t support HDMI input directly, there are workarounds using adapters like USB-C to HDMI or VGA to HDMI.

Connection methods to use Mac as second monitor for PC with HDMI

Before You Begin:

Identify the ports on your Mac and PC
Use the appropriate adapters (MacBooks may require a USB-C Digital AV Multiport Adapter)

👉 How to Set It Up:

Plug the HDMI/adapter into your PC
Connect the other end to your MacBook
Enable screen sharing on your Windows PC

Note: Not all Macs support HDMI input, so this method may be limited based on your model. It's most feasible with a Mac Mini, and trickier with MacBook or iMac without third-party software.

Troubleshooting Common Issues

Even with the best tools, hiccups can happen. Here’s how to fix the most common problems:

Can't Connect?

Double-check Wi-Fi connection on both devices
Temporarily disable firewall or antivirus software
Restart both the DeskIn app and your devices
Make sure DeskIn is up-to-date

Lag or Delay?

Ensure a strong Wi-Fi signal
Close bandwidth-heavy apps like video calls or downloads
Lower display quality settings in DeskIn
Consider switching to a wired connection

Display Looks Off?

Check your Mac’s native resolution
Adjust scaling in both DeskIn and Windows display settings
Try using Mac in clamshell mode (MacBook lid closed with external keyboard/mouse)

Conclusion: Boost Productivity with the Setup You Already Own

Turning your Mac into a second monitor for your PC isn’t just a clever workaround. It’s a practical, budget-friendly way to increase your productivity and make the most of the devices you already have. With tools like DeskIn, setting up a dual-screen workspace becomes fast and accessible, even for those with minimal technical experience.

Whether you're working on creative projects, managing spreadsheets, or simply trying to reduce window-switching fatigue, extending your display can significantly improve your workflow.

How to Play iPhone Games on Android: Complete Guide for Mobile Gamers in 2025

Can You Play Android Games on an iPhone?
Technically, it is not possible to run Android games directly on an iPhone. This is due to the distinct differences in operating systems and application frameworks between Android and iOS. Apple’s iOS is a closed ecosystem with strict controls over app installations and permissions, which prohibits the direct execution of Android applications.

Running Android Apps on an iPhone

While Android games are not natively supported on iPhones, there are workarounds that allow users to access Android applications and games from their iOS devices. One such method involves utilizing remote access software to bridge the two platforms.

Method 2: Android Emulators for iOS

Another method to run Android apps on an iPhone is through Android emulators developed for iOS. These emulators are designed to simulate the Android environment, allowing access to apps such as Google Maps, Google Photos, and even Play Store games.

However, many iOS-compatible emulators require jailbreaking the device. Jailbreaking not only introduces security vulnerabilities but may also void the iPhone’s warranty. Due to these risks, the use of emulators is generally discouraged.

Instead, DeskIn offers a safer, more stable alternative that allows remote access without compromising system integrity.

Conclusion

While it is not possible to natively install or run Android games on an iPhone, remote access tools like DeskIn offer a reliable workaround. With DeskIn, users can remotely control their Android devices from an iOS device and enjoy Android games without switching platforms or resorting to risky modifications. For a secure and high-performance experience, DeskIn remains the preferred solution for accessing Android games on iOS.

This is by design, but for those managing remote PCs, it's a headache.
