Mirroring your PC screen to a TV can open up a whole new world of big-screen functionality. Whether you want to stream PC games on the largest display possible or use your TV as a giant wireless monitor, screen mirroring makes it happen seamlessly. With the right tools, you can mirror your computer to television in just a few quick steps. This comprehensive guide will walk you through all the top options to go from PC to TV, so you can find the best match for your specific setup and needs.
Wired Connection Methods
If you don‘t mind stringing a cable between devices, wired options provide simple, reliable mirroring without any lag or wireless interference.
HDMI
HDMI is the most common way to mirror PC to TV with a cable. This digital audio/video interface has become the standard across most modern televisions, monitors, and computers. You likely have HDMI ports on both your PC and TV already.
To use HDMI mirroring, simply connect an HDMI cable between the HDMI output port on your computer and an HDMI input on your television. HDMI cables are widely available from electronics retailers like BestBuy often for under $10.
Once plugged in, you‘ll need to select the correct TV input on your television and enable external display output from your PC. HDMI can handle resolutions up to 4K and carries both audio and video signals. According to Statista, 90% of U.S. households have at least one HDMI compatible TV as of 2022.
Pros
- Ubiquitous – HDMI is universal on modern devices
- High resolutions – Supports up to 4K
- Audio and video – Carries both over one cable
- Low latency – Real-time mirroring
Cons
- Limited range – Short cable run distances
- Manual switching – Must change TV inputs
- No mobility – Must be wired connection
VGA
If your computer has a VGA output, you can use a VGA cable to mirror to your television‘s VGA input. This analog video standard has been around since the 1980s but still offers a simple way to connect older PCs and TVs.
VGA only carries video signals, so you‘ll need separate speakers or headphones connected to your PC for audio. For the best experience, try to match PC and TV resolutions since VGA tops out at 1080p and doesn‘t scale well. VGA cables are widely available for under $10.
Per Statista, only 15% of TVs sold in 2022 include VGA inputs, so it has limited compatibility with newer televisions. However, it can be a handy option for older displays.
Pros
- Ubiquitous on older devices
- Inexpensive cables
- Easy to find ports
Cons
- Analog video only
- Lower resolutions
- No audio signal
- Limited TV compatibility
DVI
The digital visual interface (DVI) standard emerged in the late 90s and early 2000s as an alternative to VGA and predecessor to HDMI. Some older desktop PCs and monitors have DVI outputs instead of VGA or HDMI.
You can convert a DVI signal to HDMI using a simple passive DVI to HDMI adapter or cable. This lets you connect PCs with DVI to modern televisions with HDMI inputs. Like VGA, DVI carries only video so you‘ll need external audio. Resolution tops out at 1080p/60Hz.
Since DVI has been largely phased out in favor of HDMI, only around 10% of new televisions still include DVI ports. So while useful for legacy systems, DVI has very limited relevance for most modern hardware.
Pros
- Converts digital signal to HDMI
- Passive/inexpensive adapters
- Useful for older PCs
Cons
- Video only, no audio
- Limited TV compatibility
- Inferior to native HDMI
Wireless Screen Mirroring Methods
If mobility is a priority, wireless options allow you to mirror your PC screen to the TV across the room without any restrictive cables. This gives you flexibility to connect from anywhere in Wi-Fi range.
Miracast
Miracast is a great wireless choice supported on many newer Windows PCs and televisions. This Wi-Fi direct mirroring protocol lets you broadcast your computer‘s display to any Miracast-enabled TV.
Here‘s how easy it is to connect:
-
Ensure Miracast is enabled on your Windows PC under Settings > Devices > Bluetooth & Other Devices

Chromecast Built-in
Chromecast is another popular wireless option allowing you to mirror your Chrome browser from a PC to your TV screen. Many smart TVs now include Chromecast built-in, including models from Sony, TCL, Hisense, and more.
Chromecast works a bit differently than Miracast in that it mirrors only your current Chrome tab rather than your entire display. Here‘s how to set it up:
-
Make sure your Chromecast-enabled TV and PC are on the same Wi-Fi network.
-
In the Chrome browser on your computer, click the 3-dot menu > Cast.
-
Choose your Chromecast TV from the target device list and click "Cast."
-
Your active Chrome tab will now be mirrored on the television. Anything displayed in your PC browser will also show on the TV.
The Chromecast protocol is optimized for smooth streaming, so performance is generally solid even over Wi-Fi. You can cast up to 4K quality depending on hardware capabilities. And best of all, there‘s no additional cost since Chromecast comes built into compatible smart TVs.
According to Google, over 80 million Chromecasts and Chromecast built-in devices have been sold to date. The latest Chromecast protocol is also available on many set-top boxes like Roku and game consoles.
Pros
- No extra hardware/fees needed
- Optimized streaming performance
- Cast up to 4K quality
- Mirror Chrome browser only
Cons
- Limited to Chrome browser
- Some smart TVs lack support
- Tab mirroring, not entire display
Third-Party Apps
If your devices don‘t support native standards like Miracast or Chromecast, third-party mirroring apps provide additional options. Popular choices like AirParrot and ApowerMirror allow PC to TV mirroring across various brands and platforms.
These apps work by installing a sender app on your Windows/Mac computer and a receiver app on your smart TV. As long as both devices are on the same Wi-Fi network, the apps handle mirroring your computer‘s full display to the television.
For smart TVs, AirParrot and ApowerMirror are compatible with Samsung, LG, Android TV, Amazon Fire TV, Roku, and more. Some also allow interactive features like using the TV as a giant wireless touchscreen to control your PC. Convenience does come at a small cost though, with most apps requiring paid subscriptions starting around $2-$5 per month.
Make sure to check for platform and version compatibility before choosing a third-party solution. And be prepared for some potential lag compared to native mirroring standards. But for maximum flexibility, these apps fill in the gaps to connect PCs and TVs across manufacturers.
Pros

Optimizing Your Wi-Fi Network for Screen Mirroring
To achieve the best wireless screen mirroring results, having a strong Wi-Fi connection is key. With bandwidth-intensive video streaming, weak Wi-Fi can ruin the experience with frozen frames, audio cutouts, or display disconnects.
Here are a few tips to optimize your home Wi-Fi network for smooth mirroring performance:
-
Upgraded router – Invest in a robust Wi-Fi 6 (802.11ax) router for the latest and greatest wireless speeds and range. This ensures plenty of bandwidth for 4K or 1080p mirroring across rooms.
-
5 GHz network – Make sure to connect mirroring devices to your router‘s 5 GHz network rather than the more interference-prone 2.4 GHz band. 5 GHz provides faster close-range speeds.
-
Bandwidth benchmarks – Use a tool like Ookla Speedtest to measure your network‘s real-world throughput. Shoot for minimum 200 Mbps download speeds for 4K mirroring or 25 Mbps for 1080p.
-
Line-of-sight placement – Position your router in a central location in direct line-of-sight with your PC and TV for the cleanest wireless signal to both. Avoid objects that can block or degrade Wi-Fi.
-
Reduce interference – Limit other high-bandwidth activities like streaming on multiple devices. Turn off microwave ovens and other appliances that can pollute the wireless spectrum when mirroring.
With the right network environment tuned for performance, wireless screen mirroring can be fast and responsive. Running an Ethernet cable to wired devices like smart TVs or consoles can also help reserve more Wi-Fi capacity for your PC.
