Can I Cast Steam Link from Phone to TV? The Ultimate Guide for 2025

Hey there! Loring here. Steam Link is one of my favorite pieces of technology for streaming PC games anywhere in the house. In this guide, I‘ll share everything I‘ve learned about casting Steam games from your phone to TV using Steam Link in 2024.

How Game Streaming with Steam Link Works – In Depth

Steam Link uses some neat video streaming technology under the hood to send your gameplay from a gaming PC to other devices. Here‘s a deeper look at what‘s involved:

• It encodes and compresses the video output from your PC games using H.264 video encoding. This shrinks the size while retaining quality.

• Your controls and inputs are sent back to the PC using custom network protocols built by Valve. This two-way communication enables remote play.

• On the device side, Steam Link decodes the video stream and displays it on your screen. This happens in real-time so the video keeps flowing constantly.

• To reduce latency, it streams over UDP protocol unlike TCP used for web traffic. UDP doesn‘t check for packet loss but delivers data faster.

• You‘ll need a home internet speed of at least 10-20 Mbps for smooth 720p streaming or 25-50 Mbps for crisp 1080p visuals.

Now let‘s look at the recommended hardware specs for the best game streaming experience:

PC requirements:

• Quad core CPU @ 3 GHz or higher
• High-end NVIDIA or AMD GPU
• 8 GB RAM
• Windows 10 or 11
• Ethernet connection preferred

Router requirements:

• Dual band router (2.4 GHz + 5 GHz)
• 802.11ac WiFi or newer
• Ethernet ports for wired connections
• Good signal coverage throughout home

TV requirements:

• 1080p or 4K TV
• HDMI port
• 5GHz WiFi or Ethernet port
• Game mode enabled for low latency

Comparing Game Streaming Resolutions and Internet Speeds

Here is a quick reference table of the resolutions supported by Steam Link and the internet speeds needed:

Resolution	Minimum Internet Speed	Ideal Internet Speed
720p	10 Mbps	20+ Mbps
1080p	25 Mbps	50+ Mbps
1440p	40 Mbps	80+ Mbps
4K	80 Mbps	100+ Mbps

As you can see, faster internet allows you to stream at higher quality. I recommend Ethernet cables for all stationary devices for the most stable connections. Wi-Fi works fine too but is prone to interference.

The Rapid Rise of Cloud Gaming

Cloud gaming services are exploding in popularity. According to Accenture, the global cloud gaming market is predicted to grow from $387 million in 2021 to over $5 billion by 2026.

The number of cloud gaming users is also expected to jump from 10 million in 2020 to around 75 million by 2025 according to Juniper Research.

Major companies like Sony, Microsoft, Amazon, Google, Nvidia and more are investing heavily in building cloud infrastructures to deliver games on demand like Netflix.

This means the future will likely be dominated by services that stream games over the Internet instead of relying on local game streaming like Steam Link. More on this later!

How Different Game Genres Perform With Streaming

Not all games stream equally well. Here are some streaming performance guidelines for popular genres:

• Slow paced games like turn-based strategy and RPGs stream perfectly fine even at higher latencies.

• Fast paced competitive games like racing sims and fighting games require very low latency and high frame rates.

• Mouse and keyboard heavy games like RTS titles are harder to play without native PC controls.

• Controller based games like platformers stream very well to TVs and mobile devices with gaming controllers.

I‘ve found slower paced single player games work great on TVs. But I prefer playing competitive shooters and MOBAs natively on the PC for best performance.

How To Enable Remote Access for Steam Link

To allow Steam Link to connect from outside your home, you‘ll need to enable port forwarding on your router:

1. Log in to your router‘s admin page (192.168.1.1) and go to its port forwarding or virtual server settings.

2. Forward TCP ports 27031 and 27036 to your gaming PC‘s local IP address.

3. Save settings and restart router. Your PC will now have open ports for Steam Link anywhere!

With port forwarding set up, you can stream games from your PC to any device when traveling – super handy!

Level Up Mobile Gaming with Wireless Controllers

Playing Steam games on your phone is awesome, but touch controls aren‘t ideal. Here are some controller accessories I recommend:

• The Razer Kishi attaches to your phone providing Switch-like handheld controls. Very fun for remote play!

• Backbone One is a similar snap-on controller for iPhones with a great companion app.

• For big screen gaming, the 8BitDo Ultimate Bluetooth Controller works great across Windows, Android, Mac and more.

• Can‘t go wrong with the tried and tested Xbox Wireless Controller – connects easily to phones and TVs.

Controllers elevate mobile gaming to the next level. I always keep one in my bag for gaming on the go!

Comparing PC vs TV Gaming with Steam Link

Let‘s weigh the pros and cons of playing games natively on PC compared to streaming over Steam Link to your TV:

PC

• Highest performance possible
• Unlimited control options
• Mod support in games
• Adjust all settings easily
• Dedicated high refresh rate monitor

TV

• Big screen couch gaming
• Lean back with controller
• Gather around for co-op/party games
• Split screen multiplayer support
• Play PC exclusives from comfort

I find myself using both equally depending on my mood and the game genre. Local co-op party games are super fun on the living room TV with friends. But competitive online shooters I play seriously on my gaming PC setup.

My Experiences with Steam Link and Game Streaming

I‘ve used various game streaming services over the years with mixed success. Here are some quick impressions:

• Steam Link works great for streaming my Steam library to any screen in the house. Very convenient thanks to the mobile app.

• Nvidia GameStream is fantastic when paired with an Nvidia Shield TV. Low latency and supports 4K HDR. Sad it‘s being discontinued.

• Chromecast streaming gets the job done but I notice more compression artifacts and lag compared to native apps.

• Google Stadia impressed me initially but the library and adoption never took off. Being shut down now.

• Xbox Cloud Gaming has vastly improved recently. Great for trying out Game Pass titles easily without needing to install them.

Overall, I find dedicated gaming devices or wired connections provide the most reliable results for local game streaming. But cloud gaming services continue to rapidly improve.

Alternatives like Moonlight and Parsec

Here are some more advanced open source options I‘ve tested for streaming games over Internet:

• Moonlight – Streams from PC to devices like Steam Link but with more configuration options. Lower latency than Steam Link in my experience.

• Parsec – Lets you stream full remote PC desktop and games. I use the web client to access my home PC from anywhere. More suited for prod usage than gaming.

Moonlight is great for low latency game streaming while Parsec shines for general remote computing. I sometimes use Moonlight if I‘m noticing lag or glitches with Steam Link.

Tips for Smooth PC to TV Game Streaming

To avoid hiccups when casting your PC games to the living room TV, follow these tips:
