How to Cast Your PC to a Xumo TV

Yes, you can cast your PC to a Xumo TV, but the method depends on which Xumo device you own

Xumo is a streaming service owned by Comcast, and it comes built into certain TV models and set-top boxes. If your TV has Xumo built in, you can mirror your PC screen using Miracast, which is Windows' wireless display standard. If you have a Xumo set-top box instead of a Xumo-enabled TV, your casting options are more limited — you'll need to use an HDMI cable or a separate streaming device.

The fastest way to know what you have is to look at your TV's input menu or the box itself. If it says "Xumo" on the screen or in the settings, you likely have a Xumo-enabled TV. If you have a separate black or silver box connected to your TV, that's a Xumo set-top box, and you'll need a different approach.

Key Takeaways

Xumo-enabled TVs support Miracast, which lets you wirelessly mirror your PC screen without installing extra software.
To use Miracast, your PC and TV must be on the same Wi-Fi network, and your TV's Miracast setting must be turned on.
Xumo set-top boxes do not support Miracast, so you will need an HDMI cable or a separate streaming device like a Roku or Fire Stick.
If Miracast fails, check that your PC's Wi-Fi driver is up to date and that your TV is not in use by another device.

Casting from Windows to a Xumo-enabled TV using Miracast

If you have a Xumo-enabled TV, the built-in Miracast receiver means you can cast directly from Windows without downloading anything. Start by making sure both your PC and TV are connected to the same Wi-Fi network. Then open the Windows Settings app, go to System, select Display, and scroll down to Multiple displays. Click Connect to a wireless display.

Windows will search for available devices. Your Xumo TV should appear in the list with its model name or "Xumo TV." Click it to connect. The first time you connect, your TV may ask you to confirm the pairing. Once confirmed, your PC screen will mirror to the TV. You can adjust the display mode by pressing Windows key + P to choose between mirroring, extending, or using only the TV as your display.

If your TV does not appear in the list, check that Miracast is enabled on the TV itself. Go to your TV's settings menu, look for Display, Miracast, or Screen Mirroring, and make sure it is turned on. Some Xumo TVs require you to enable this in the Xumo app settings rather than the TV settings.

Turning on Miracast on your Xumo TV

The exact steps vary depending on your TV's brand and model, but Xumo is most commonly found on Comcast-branded TVs and some LG and Samsung models. Look for your TV's settings menu — usually accessed with a button labeled Menu or Settings on the remote. Navigate to Display, Network, or Connected Devices.

Inside that menu, search for Miracast, Screen Mirroring, Wireless Display, or Cast. The exact name depends on the manufacturer. Toggle it to On. If you cannot find it in the TV settings, open the Xumo app on your TV and check its settings menu for a casting or display option. Some Xumo TVs hide the Miracast toggle inside the app rather than the system settings.

What to do if you have a Xumo set-top box instead of a Xumo TV

Xumo set-top boxes — the separate devices that connect to your TV — do not have built-in Miracast support. Your best option is to use an HDMI cable to connect your PC directly to the box or TV. Plug one end into your PC's HDMI port and the other into an available HDMI input on your TV or Xumo box. Then switch your TV to that input using the remote.

If you want wireless casting without buying a cable, you can add a separate streaming device. A Roku, Amazon Fire Stick, or Google Chromecast plugs into an HDMI port on your TV and supports screen mirroring from a PC. These devices cost between $25 and $50 and work independently of your Xumo box — your TV will straightforward switch between inputs.

Troubleshooting when your PC will not connect to the Xumo TV

If your PC finds the TV but the connection fails, or if the TV does not appear in the list at all, start by checking that both devices are on the same Wi-Fi network. Open your PC's Wi-Fi settings and your TV's network settings and confirm they show the same network name. If they are on different networks, connect the PC to the TV's network.

Next, restart both devices. Turn off your TV completely, wait 10 seconds, and turn it back on. Then restart your PC. After both have fully booted, try connecting again. If the problem persists, update your PC's Wi-Fi driver. Go to Device Manager on your PC, find Network adapters, right-click your Wi-Fi adapter, and select Update driver. Choose Search automatically for updated driver software.

If Miracast still does not work, check whether another device is currently casting to the TV. Xumo TVs can usually only receive one Miracast connection at a time. If a phone or tablet is already connected, disconnect it first. You can also try forgetting the TV from your PC and reconnecting. In Windows Settings, go to Bluetooth & devices, find your TV in the list, click it, and select Remove device. Then try connecting again from scratch.

Using your PC as a media source instead of casting the whole screen

If you only want to watch videos or music from your PC on the Xumo TV, you may not need to cast the entire screen. Many streaming apps — like Netflix, YouTube, and Spotify — have built-in casting buttons. Open the app on your PC, look for a Cast icon (usually three curved lines), click it, and select your Xumo TV from the list. This uses less bandwidth and battery than mirroring your whole screen.

This method works even if Miracast is not enabled on your TV, because the app handles the connection directly. It also means you can use your PC for other tasks while the video plays on the TV — the app is streaming to the TV independently, not mirroring your screen.

When to use an HDMI cable instead of casting

Miracast is convenient, but it is not always the best choice. If you are doing something that requires low latency — like playing a game or editing video — an HDMI cable will give you a more stable, faster connection with no lag. HDMI also does not depend on Wi-Fi strength, so it works reliably even if your network is slow or crowded.

If your PC is far from your TV or your Wi-Fi signal is weak in that room, an HDMI cable is also more reliable than Miracast. A standard HDMI cable costs $5 to $15, and most PCs have at least one HDMI port. If your PC does not have HDMI, you can use a USB-C to HDMI adapter (usually $10 to $20) or a DisplayPort to HDMI adapter, depending on your PC's ports.

Frequently Asked Questions

Do I need to install software to cast my PC to a Xumo TV?

No. If your TV has Xumo built in and supports Miracast, Windows has the casting feature built in. You do not need to read or install anything. Just make sure both devices are on the same Wi-Fi network and that Miracast is enabled on the TV.

Can I cast from a Mac to a Xumo TV?

Miracast is a Windows standard, so Macs do not support it natively. You can use an HDMI cable with a USB-C or Thunderbolt adapter, or you can add a separate streaming device like an Apple TV, Roku, or Fire Stick that supports AirPlay or other Mac-compatible casting methods.

Will casting slow down my internet?

Miracast uses your local Wi-Fi network but does not consume internet bandwidth — it sends the signal directly between your PC and TV on your home network. If your Wi-Fi is slow or crowded, the connection may be choppy, but it will not affect your internet speed for other devices.

What if my Xumo TV is too old to support Miracast?

Older Xumo TVs may not have Miracast built in. Check your TV's manual or settings menu to confirm. If it does not support Miracast, use an HDMI cable or add a separate streaming device like a Roku or Fire Stick to your TV's HDMI port.

Can I cast to a Xumo TV from my phone or tablet?

Yes. iPhones and iPads can use AirPlay if your Xumo TV supports it (check your TV's settings). Android phones and tablets can use Miracast the same way a PC does. Open your phone's settings, look for Display or Connected devices, find the casting option, and select your TV from the list.
