The short answer is yes, but with caveats. While the original Steam Link hardware is limited to 1080p, the Steam Link app, available on various platforms, does support 4K streaming. The experience, however, is heavily dependent on your hardware, network, and software setup. Let’s break down the specifics and explore how to achieve the best possible 4K streaming experience.

Understanding Steam Link’s 4K Capabilities

The confusion around Steam Link and 4K stems from the device’s evolution. The dedicated Steam Link box, now discontinued, was capped at a maximum resolution of 1080p. This limitation was due to the hardware’s processing power and network capabilities at the time.

However, Valve recognized the growing demand for higher resolution streaming and extended Steam Link’s functionality through a dedicated application. This Steam Link app is available on a range of devices, including:

Android devices: Smartphones, tablets, and Android media players.
Samsung Smart TVs: Select models, though support is ending soon.
Raspberry Pi: A popular choice for DIY enthusiasts.
Apple TV: 4K 60fps is the limit here, unfortunately.

The Steam Link app leverages the processing power of the host PC to encode the game and stream it to the client device at the desired resolution. This means that if your host PC can run a game at 4K and your network is capable of handling the bandwidth, you can stream in 4K using the Steam Link app on a compatible device.

Enabling 4K Streaming on the Steam Link App

To enable 4K streaming through the Steam Link app, you’ll need to configure both the Steam client on your host PC and the Steam Link app on your client device. Here’s a step-by-step guide:

Host PC Configuration (Steam Client)

Open the Steam client on your host PC.
Navigate to Settings > Remote Play > Advanced Host Options.
Ensure that the “Enable Hardware Encoding” option is checked. This offloads the encoding process to your GPU, which is crucial for achieving smooth 4K streaming.
Consider checking “Change desktop resolution to match streaming client”. This can improve performance by reducing the load on your PC, especially if your host PC’s monitor is at a higher resolution than the streaming client’s display.
In the Advanced Host Options, experiment with different encoding options. NVFBC (Nvidia Framebuffer Capture) and AMD VCE (Video Coding Engine) offer excellent performance with minimal latency on compatible hardware.

Client Device Configuration (Steam Link App)

Launch the Steam Link app on your client device.
Navigate to Settings > Streaming.
Select the “Advanced Client Options” or “More…” button.
Locate the “Resolution Limit” option.
Set the resolution to “4K” or “3840×2160”.
Adjust the “Bandwidth Limit” to a value appropriate for your network. A wired connection is highly recommended for 4K streaming, and a bandwidth limit of at least 50 Mbps is generally necessary.
If you encounter performance issues, try lowering the “Bandwidth Limit” or selecting a lower resolution.
Explore the “Display” settings in your device to ensure that the connected display (TV or monitor) is configured to the appropriate resolution and refresh rate.

Performance Considerations for 4K Streaming

Achieving a smooth and enjoyable 4K streaming experience with Steam Link requires careful consideration of several factors:

Host PC Hardware: Your host PC needs a powerful CPU and GPU to encode the game at 4K resolution without significant performance drops. A dedicated graphics card (Nvidia GeForce GTX 1070 or AMD Radeon RX 580 or better) is highly recommended.
Network Bandwidth: 4K streaming requires a robust network connection. A wired Ethernet connection is strongly preferred over Wi-Fi, as it provides a more stable and reliable connection. Ensure your router supports Gigabit Ethernet and has sufficient bandwidth available.
Client Device Processing Power: While the host PC handles the encoding, the client device needs enough processing power to decode and display the stream smoothly. Older or less powerful devices may struggle to maintain a consistent frame rate at 4K resolution.
Encoding Settings: Experiment with different encoding settings in the Steam client to find the optimal balance between visual quality and performance. Using hardware encoding is crucial, and you may need to adjust the bitrate and other settings to avoid lag or stuttering.
Game Settings: Lowering the in-game graphics settings can significantly improve streaming performance. Reducing the resolution, texture quality, and other visual effects can reduce the load on your host PC and improve the streaming experience.

Alternatives to Steam Link

While Steam Link is a convenient option for streaming games, it’s not the only solution available. Several alternatives offer similar or even superior performance, particularly for 4K streaming:

Moonlight: An open-source streaming solution that leverages Nvidia’s GameStream technology. Moonlight generally offers lower latency and better image quality than Steam Link, especially when streaming at high resolutions.
Parsec: A popular choice for cloud gaming and remote collaboration. Parsec is known for its low latency and excellent performance, making it well-suited for fast-paced games.
Nvidia GeForce Now: A cloud gaming service that streams games directly to your device. GeForce Now offers a wide selection of games and supports 4K streaming with RTX capabilities.
AMD Radeon Remote Gaming: AMD’s solution for streaming games from your PC to other devices. Similar to Steam Remote Play, but optimized for AMD hardware.

These alternatives can provide a better 4K streaming experience depending on your hardware configuration and network conditions.

Discontinued Steam Link on Samsung TVs

It’s important to note that the Steam Link app will no longer be available on Samsung TVs after November 30th, 2023. This is due to Samsung ending support for the application, which was created and maintained by them. This does not affect the availability of the Steam Link app on other platforms.

Optimizing Steam Remote Play

To achieve the best possible streaming experience, consider the following tips:

Prioritize Wired Connections: Use Ethernet cables whenever possible for both the host PC and the client device.
Update Drivers: Ensure that your graphics card drivers are up to date.
Close Unnecessary Applications: Close any applications running in the background on your host PC that may be consuming resources.
Monitor Network Usage: Use a network monitoring tool to identify any bottlenecks or congestion on your network.
Experiment with Different Codecs: Try different encoding codecs in the Steam client to find the one that works best for your hardware.
Adjust Bandwidth Limits: Experiment with different bandwidth limits in the Steam Link app to find the optimal balance between visual quality and performance.

By following these tips, you can improve the streaming experience and minimize lag and stuttering.

In Conclusion

While the original Steam Link hardware is limited to 1080p, the Steam Link app offers 4K streaming capabilities on compatible devices. Achieving a smooth and enjoyable 4K streaming experience requires careful consideration of your hardware, network, and software configuration. If you encounter performance issues, consider exploring alternative streaming solutions like Moonlight or Parsec.
