You're sitting there with a massive 4K screen in the living room and a tiny laptop on your lap. It feels wrong. Why am I squinting at a 14-inch spreadsheet or a grainy Discord stream when I have sixty-five inches of HDR glory ten feet away? Honestly, the dream of figuring out how to stream my pc to my tv is often met with a nightmare of stuttering video, audio that doesn't match the lips, and "No Signal" screens that make you want to throw your router out the window.
Wireless tech has come a long way, but it isn't magic.
If you want to move your desktop experience to the couch, you have to choose between convenience and performance. You can't always have both. Sometimes a $10 cable beats $1,000 worth of networking gear. Other times, the software already built into your television is more than enough to get the job done without buying a single extra dongle. Let's get into what actually works in 2026.
The HDMI Cable: Why Boring is Better
Wires are annoying. I get it. Nobody wants a black cord snaking across the hardwood floor where the dog can trip on it. But if we are being real for a second, physical cables are the only way to get zero latency. If you are trying to play a fast-paced game like Counter-Strike or even just a snappy platformer, wireless is going to frustrate you.
Modern HDMI 2.1 cables support 4K at 120Hz. Most wireless solutions struggle to hit 4K at 60Hz without compressing the colors into a muddy mess. If your PC and TV are in the same room, just buy a long cable. Look for "Active HDMI" cables if you need to go over 15 feet; they have tiny chips inside to boost the signal so it doesn't degrade before it hits the port. It’s the "set it and forget it" solution that never requires a firmware update or a Wi-Fi password.
Miracast and the Built-in Windows Solution
Windows has this thing called "Project." You hit Windows Key + K, and a little menu pops up on the right side of your screen. This uses Miracast. It’s basically a Wi-Fi Direct connection between your computer and the TV.
It's... fine.
The problem with Miracast is that it’s notoriously finicky. One day it works perfectly; the next day, your TV won't show up in the list for no reason at all. It also tends to be heavy on the "lag." You'll move your mouse on the laptop, and a half-second later, the cursor crawls across the TV. It’s okay for showing off vacation photos or a PowerPoint, but please don't try to watch a high-bitrate movie this way. The macroblocking—those ugly little squares in dark scenes—will drive you crazy.
When to use Miracast:
- Quickly sharing a website with people in the room.
- Displaying static documents.
- Emergency situations where you forgot your adapter.
The Steam Link App (It’s Not Just for Games)
Valve discontinued the physical Steam Link hardware years ago, but the software is a masterpiece. This is arguably the best way to handle how to stream my pc to my tv if you own a smart TV (Samsung, Sony, or anything with Android TV/Google TV) or an Apple TV box.
You install the app on the TV, open Steam on your PC, and pair them with a PIN.
Here is the secret: even though it's called Steam Link, you can use it to stream your entire desktop. Once the app is running, you just minimize Steam’s "Big Picture Mode," and boom—you have full control over your Windows environment. It uses a custom encoding protocol that is much more efficient than Windows’ native casting. If both your PC and your TV are plugged into the router via Ethernet cables, the experience is nearly indistinguishable from a direct HDMI connection. Wi-Fi works too, but you’ll want a 5GHz or 6GHz (Wi-Fi 6E) band to avoid the stuttering caused by your neighbor’s microwave or a busy smartphone.
Chromecast and the Google Ecosystem
If you use Chrome or the Edge browser, you already have a streaming tool. You click the three dots in the corner, hit "Save and Share," then "Cast." You can choose to cast a single tab or your entire desktop.
Google’s approach is great for video. If you cast a YouTube video or a Netflix tab, the TV often takes over the stream directly from the internet, which saves your PC's battery and ensures the highest quality. However, if you "Cast Desktop," the quality takes a massive hit. It’s clearly meant for browsing, not for high-end media consumption.

Moonlight and Sunshine: The Pro Way
If you’re a power user, you need to know about Moonlight. Originally, this was a way to use NVIDIA’s "GameStream" protocol on non-NVIDIA devices. Since NVIDIA killed off GameStream, the community created an open-source "server" called Sunshine.
This is the gold standard.
Sunshine runs on your PC (doesn't matter if you have an AMD, Intel, or NVIDIA GPU), and Moonlight runs on your TV or streaming box. It is significantly faster than Steam Link. It supports HDR, 120fps, and high-bitrate 4K. Setting it up takes about twenty minutes and a little bit of technical patience, but once it’s running, you’ll never go back to basic casting. It makes the PC feel like it's actually inside the TV.
Hardware Matters More Than You Think
You can have the best software in the world, but if you're trying to stream to a $200 TV with a bottom-tier processor, it's going to suck. The "brains" inside your TV have to decode the incoming video stream in real-time. Cheap TVs have slow decoders, which adds "display latency."
If your TV’s built-in apps are sluggish, do yourself a favor and buy a dedicated streaming device.
- NVIDIA Shield TV Pro: Still the king for local streaming. It handles almost every video format and has a great Ethernet port.
- Apple TV 4K: Incredible hardware, though the ecosystem is a bit locked down. The Moonlight app on Apple TV is stellar.
- Chromecast with Google TV (4K): A solid budget pick, but it can struggle with very high-bitrate local streams.
Why Your Wi-Fi is Probably the Problem
Most people complain that streaming looks blurry. This usually isn't the PC's fault. It’s the "jitter" on your wireless network. Wi-Fi sends data in bursts. If a packet gets lost, the video freezes or drops in resolution to compensate.
If you can't run an Ethernet cable, at least make sure you're on the 5GHz band. The 2.4GHz band is crowded and slow. It’s like trying to drive a Ferrari through a school zone at 3:00 PM. Move your router closer to the TV, or look into "Powerline Adapters" that send internet signals through your home's electrical wiring. They aren't perfect, but they are often more stable than Wi-Fi for video streaming.
Setting Up for Success: A Checklist
Before you start, change your PC’s resolution to match the TV. If you have a 1080p monitor but a 4K TV, your PC is going to try to send a 1080p signal, and it will look fuzzy on the big screen. Go into Settings > System > Display and kick that resolution up.
Also, turn on Game Mode on your TV settings. This turns off all the "motion smoothing" and "noise reduction" junk that TV manufacturers add. Those features look okay for movies, but they add a massive amount of delay to the image. In Game Mode, the TV processes the image as fast as possible, which is exactly what you want when streaming from a computer.
Quick Fixes for Common Issues:
- No Sound: Right-click the speaker icon on your PC taskbar and make sure the "Output Device" is set to the TV or the streaming software (like Steam Streaming Speakers).
- Black Bars: Match the aspect ratio. Most TVs are 16:9. If your PC monitor is an ultrawide (21:9), you're going to have big black bars on the top and bottom of your TV.
- Laggy Mouse: This is almost always network interference or the TV not being in Game Mode.
Actionable Next Steps
To get the best result today, start by checking if your TV has a native Steam Link or Moonlight app in its app store. If it does, grab a controller or a wireless keyboard/mouse combo with a USB dongle. Plug that dongle directly into the TV (most smart TVs support HID devices).
If the wireless lag is too much, skip the headache and order a 15-foot Certified Premium High Speed HDMI cable. It costs less than a pizza and solves every single problem mentioned in this article instantly. For those determined to stay wireless, ensure your router is positioned high up and away from other electronics to give your PC the best possible path to the screen.

Start with the Steam Link app for the easiest setup, and if you find yourself wanting more control and better image quality, graduate to the Sunshine/Moonlight combo. Just remember to keep your PC's power settings to "Never Sleep" while you're in the other room, or your stream will end abruptly the moment the computer decides it’s time for a nap.
