Have you ever struggled with laggy remote desktop control during remote work? Or felt frustrated by the blurry screen quality of your current screen-sharing app? These cross-platform limitations and latency issues are exactly what most users experience when sharing screens remotely.

Don’t worry — this article highlights the 6 best screen sharing software for 2025, from DeskIn (known for high-quality 4K transmission) and Chrome Remote Desktop (a fast and free option), to AirDroid Cast, which lets you wirelessly cast your PC screen to a TV.
We’ll help you quickly compare and find the most stable, seamless, and suitable screen-sharing tool for your needs — making teamwork smoother than ever.

Quick Overview: 6 Best Screen Sharing Software

1. DeskIn: High-Quality Transmission and Multi-Functional Sharing

In remote collaboration and technical support, smooth and crystal-clear screen sharing is crucial. DeskIn excels with its ultra-low latency and high-resolution 4K video streaming. Whether you’re conducting software training, design reviews, or code walkthroughs, DeskIn ensures every icon, color, and line of text remains sharp — minimizing miscommunication from visual distortion.

Beyond screen quality, DeskIn also integrates voice calls and real-time chat, allowing you to communicate clearly without switching apps. This is especially useful for live technical demonstrations, keeping voice and visuals perfectly in sync.

Its whiteboard annotation tool enables drawing, writing, and highlighting directly on the shared screen — making remote teamwork as intuitive as face-to-face discussions. Combined with 4K resolution, ≤40 ms latency, and full cross-platform support, DeskIn stands out as a top-tier, all-in-one remote collaboration solution — and it’s free to use.

2. TeamViewer: Best for Mid-to-Large Enterprises

When it comes to corporate screen sharing, data security and access control are top priorities.TeamViewer allows precise connection management — you can control who connects, what they see, and for how long, and can revoke access instantly. This flexible control system ensures collaboration without compromising security.

Its image transmission quality rivals DeskIn, with optimized protocols providing smooth, high-fidelity visuals. At up to 60 fps, mouse movements and scrolling feel natural and delay-free, which is critical for interactive teaching or live software demos. However, TeamViewer’s high subscription cost may deter individuals and small teams, prompting many to seek more cost-effective alternatives.

3. Microsoft Remote Desktop: Windows Native App

Microsoft Remote Desktop (RDP) uses local rendering to achieve 15–25 ms latency, offering near-instant keyboard and mouse feedback. With support for 4K 60 fps and 32-bit color, text and UI elements stay razor-sharp.

The RemoteApp mode lets you share only one application window instead of your entire desktop — ideal for presentations or controlled ERP access. However, RDP lacks built-in chat, annotation, or file transfer features, so you’ll still need Teams or Zoom for full collaboration functionality.

4. Chrome Remote Desktop: Free and Fast for Temporary Sharing

Chrome Remote Desktop is a completely free tool ideal for quick screen sharing. With just a Chrome browser and Google account, you can connect devices across systems securely. The connection automatically adjusts image quality to match your internet speed, offering a stable experience for basic meetings and demos.

However, it lacks advanced features like multi-device management, in-app chat, and resolution control — making it less suitable for enterprise use.

If you find Chrome Remote Desktop too limited, DeskIn offers everything it’s missing — including real-time chat, adjustable resolutions, and multi-device control — for a professional-grade screen sharing experience.

5. AirDroid Cast: Best Multi-Device Compatibility

AirDroid Cast supports screen sharing and remote control between Android, iOS, Windows, and macOS, and can even cast a computer screen to a TV. Up to five devices can share to one PC, perfect for meetings or classrooms.
It offers both wireless and USB connections, with AirPlay support for Apple devices.

While it provides smooth 4K mirroring, image quality may fluctuate depending on network stability — occasional blurriness or delay may occur during wireless transmission.

6. Parsec: Built for Gamers and Creators

Parsec delivers up to 4K 60 fps streaming, with optional 4:4:4 true color for perfect color fidelity. With latency as low as 20 ms on LAN, cursor control feels as responsive as using a local machine — ideal for real-time editing, animation, or competitive gaming.

Gamers can stream from their high-end home PCs to laptops or MacBooks anywhere.
Studios use Parsec to share workstations for remote editing, rendering, or game testing. However, it lacks iOS support, mobile-to-PC control, and Chinese localization, which may limit accessibility for some users.

FAQs

What are the best free screen sharing tools?

If you’re looking for free options, Microsoft Remote Desktop is stable and efficient but limited to Windows systems.

For cross-platform needs, DeskIn is a better alternative — it supports Windows, macOS, and Linux with HD screen sharing, remote control, and voice communication, all for free.

Can I share my screen if I’m on mobile data and the other person uses Wi-Fi?

Absolutely! That’s the key advantage of third-party software like DeskIn. Both devices connect to the nearest server, which relays the stream and controls seamlessly — no router setup required.

In contrast, built-in tools like Windows Remote Desktop only work within a local network (LAN) and require complex port forwarding to connect externally, making DeskIn a far easier and more reliable choice.

Conclusion

Among all screen sharing tools, if you value maximum clarity and low latency, DeskIn is your top choice. Its 4K streaming and ≤40 ms delay make remote collaboration as natural as working side by side. Whether for cross-platform tutorials, design reviews, or live technical guidance, DeskIn ensures a flawless experience.

With integrated HD audio calls and real-time chat, DeskIn creates a complete collaboration environment where teams can discuss, annotate, and decide faster. For professionals seeking smooth, high-quality remote teamwork — DeskIn is the ultimate screen sharing solution.

In the world of gaming, milliseconds matter. One frame of lag, and boom, you’re toast. That’s why remote gaming software like Parsec became a fan favorite: smooth, responsive, and purpose-built for streaming high-performance games from one device to another.

But it’s 2025. The bar is higher now. And while Parsec walked so others could run, one platform has stepped up and sprinted ahead: DeskIn.

If you’re hunting for the best Parsec alternative, something faster, more flexible, and built for both gaming and beyond, keep reading. This one’s for you.

What is Parsec?

Parsec is a well-known remote gaming software that lets you stream games from your high-end PC to another device, be it a laptop, tablet, or low-spec machine, with impressively low latency. It's become a favorite among gamers who want LAN-like multiplayer over the internet or want to play PC games from low-end devices.

 Advantages of Parsec

• Low latency performance as low as 10–60ms on mobile networks, and 10–30ms on Wi-Fi.

• Support for 4K 60fps and even higher frame rates on high-refresh displays.

• Multiplayer rooms for local-style co-op from different locations.

Disadvantages of Parsec

• Limited to gaming use cases. No remote productivity, IT support, or collaboration tools.

• No iOS support, Apple users are left out. Parsec doesn’t support iPhones or iPads, cutting off a huge portion of mobile users from the experience.

• Stability concerns are reported during high-traffic sessions or mobile usage. Despite its low latency, Parsec can experience connection drops or stream degradation during peak usage times or unstable mobile networks.

• Lack of feature depth: no file transfers, screen extension, or clipboard sync. These are standard in modern remote tools, but absent here.

• The free version is not allowed for commercial use, making it less ideal for professionals or studios.

The Best Alternative to Parsec: DeskIn

DeskIn takes everything great about Parsec and enhances it with enterprise-level features, broader device compatibility, and rock-solid stability.

It’s not just a remote gaming software. It’s an all-in-one platform that bridges remote gaming, productivity, and remote support.

Why DeskIn is the Best Alternative to Parsec

DeskIn isn't just trying to match what Parsec does well; it's redefining the remote access experience. Here's a deeper look at what sets it apart:

Unmatched Connection Quality and Performance

DeskIn is built with gamers in mind, prioritizing low-latency and crystal-clear visuals across a variety of network conditions. While Parsec may edge slightly ahead on paper in latency over ultra-fast Wi-Fi, DeskIn proves itself in real-world environments:

• Mobile Network Latency: 30–90ms with smooth reconnection during signal drops.

• Wi-Fi (FHD): 25–50ms, maintaining input responsiveness for competitive games.

• Wi-Fi (4K): 50–100ms with consistent 60fps playback, ideal for immersive RPGs and high-motion gameplay.

Unlike Parsec, DeskIn handles latency spikes more gracefully, keeping gameplay fluid even when conditions aren't perfect.

True Cross-Platform Compatibility

DeskIn provides native support for Windows, macOS, Android, and iOS. This gives it a clear edge over Parsec, which still lacks iOS support entirely. Whether you want to game from an iPad, troubleshoot a MacBook, or work from an Android tablet, DeskIn offers full functionality across all platforms.

• Device Management to organize and tag your host machines under one account. Perfect for users with home PCs, workstations, and shared machines.

• Unattended Access so you can log in to your devices even if no one's there to click "Accept."

• Session Switching via mobile app, move between devices with just a tap.

• Remote Control of Mobile Devices for true bidirectional control, which Parsec doesn’t offer.

These features position DeskIn not only as a better remote gaming solution but also as a productivity and support powerhouse.
