If you want to know how to improve screen mirroring quality on your TV, you’ve come to the right place!
It’s a frustrating issue, especially if you’re dealing with blurry or buffering images on your TV.
The good news is that you should be able to resolve this problem in less than 10 minutes.
Let’s find out how!
To improve the screen mirroring quality, you must connect your devices to the same 5G WiFi network. Configuring your router’s QoS settings to prioritize your screen mirroring devices will also help improve the quality.
Now that you have a general idea of how to deal with this problem, let’s look at some of the things you should consider when doing screen mirroring.
Screen mirroring is essentially showing content from one device to another. In this case, it’s usually from your phone to your TV.
Your most important consideration here is the quality of your network connection.
The faster and more stable your connection is, the better the picture quality you’re mirroring.
Here’s what you should consider when you’re screen mirroring:
1. WiFi Band and Connection
Your WiFi connection plays an important part in your screen mirroring or casting quality. The faster your connection, the less chance you get blurriness or lag.
2. Signal Interference
You also want to consider signal interference, which can disrupt your connection and cause screen mirroring quality issues.
3. Software and Firmware Versions
Having the latest firmware versions on your router helps ensure that your connection quality isn’t compromised.
4. Device Proximity to the Router
The close your devices are to your router, the less chance of them suffering from quality problems.
5. Network Usage and Congestion
If you can free up your network during screen mirroring, it will ensure that you get the best quality.
Let’s now move on to the different ways how you can improve the screen mirroring quality if you suffer from blurry and buffering videos.
Bad screen mirroring quality between your phone and TV is commonly caused by a bad connection. Most of the time, you will be relying on your wireless network.
If your setup suffers from blurry or laggy screen mirroring, you first want to restart all your devices. This includes your phone and TV.
However, most importantly, you want to restart and power cycle your networking devices, especially your router.
Doing all these will reset the connections, which can greatly improve the screen mirroring quality.
If restarting your devices doesn’t resolve the issue, we can move on to the more advanced steps below.
To improve your screen mirroring quality, you also need to improve your connection.
Since it’s a challenge to hardwire your phone and TV at the same time, your most realistic option is faster and more stable WiFi.
The good news is that this solution already exists in the form of the 5GHz band.
It’s less congested and offers higher data transfer speeds which are perfect for screen mirroring and casting.
It’s also more stable as it’s not affected by outside interference.
Here’s how to activate the 5GHz band on your router:
- Using a browser, log in to your router’s admin account.
- Navigate to the Wireless menu.
- Locate the Band or Frequency menu.
- Enable or Select 5GHz.
- Click on Apply or Save.
Note: Once you enable the 5GHz band, you want to ensure that your devices are connected to it.
If you want to know how to improve screen mirroring quality iPhone, the quickest solution you can take is to turn off Bluetooth.
It’s also not limited to iOS devices, but it seems more of a problem than Android.
It’s known that the Bluetooth module can interfere with the WiFi signals, which can cause blurriness or buffering whenever you’re screen mirroring.
It’s certainly a simple solution, but it’s one of the more effective ones, especially if you always leave your Bluetooth on.
Here’s how to switch off your phone’s Bluetooth:
- Open your phone’s Settings.
- Navigate to Bluetooth.
- Toggle the switch to the Off position.
- Go to your phone’s Settings app.
- Select the Connected Devices option.
- Choose Connection Preferences.
- Go to Bluetooth, and toggle the switch Off.
Pro Tip: You can also turn off Bluetooth quickly by swiping down from the top of your phone’s screen and tapping on the Bluetooth icon.
Apart from choosing a WiFi band, another router setting you can change to improve your screen mirroring quality is the 802.11 mode.
There are several modes that your router can use.
They don’t make much of a difference unless you’re using them for intensive activities.
Some modes, like 802.11n, increase the bandwidth, which is helpful for screen mirroring.
Here’s how to change the 802.11 modes on your router:
- Use a browser to log in to your router’s admin dashboard.
- Select the Wireless option.
- Locate the Wireless band and mode option.
- Choose 802.11a or 802.11n from the drop-down.
Note: Some router models will only have options with letters like a, ac, ax, or n.
Screen mirroring is essentially projecting the content from your phone to a different display device like your TV.
If you’re having issues with screen mirroring, especially when the content on your TV is blurry, it can mean a mismatch with the resolution.
For example, if you have a 4K TV, but your downloaded content is only 720p, it means that your TV has to work to fill in a lot of missing pixels.
If you plan on mirroring or casting content from your phone to your TV, you want to ensure the resolution matches your TV.
Here’s how to adjust the video resolution of your TV:
- Open your TV’s Settings.
- Locate the option that says Screen Resolution or Output Resolution.
- Select the resolution that matches the content on your phone.
- Other TVs might refer to this as Zoom Mode.
Note: If you’re streaming and casting your screen at the same time, you want the best possible connection for improved quality.
Since screen mirroring uses network resources, making it your network’s priority is vital.
If someone is downloading or streaming 4K movies, you will surely experience blurriness or buffering with your screen mirroring.
The most effective way to prioritize your network resources for your screen mirroring would be to set up QoS on your router.
Here’s how to setup QoS for screen mirroring on your router:
- Log in to your router’s admin dashboard.
- Go to the Wireless tab.
- Find the QoS Settings and select it.
- Add a new QoS rule.
- Set your Phone and TV to the highest priority.
AP Isolation is a useful tool that improves the security of your network. However, it’s a feature that can prevent your devices from communicating properly with each other.
If you’re having problems with screen mirroring, this is a solution that you can take to improve it.
Turning AP Isolation off should allow your devices to connect with each other and improve the screen mirroring quality.
Here’s how to disable AP Isolation on your router:
- Log in to your router’s admin panel via a web browser.
- Select Wireless.
- Go to Advanced Settings.
- Find the AP Isolation menu.
- Select the On option.
Note: For the changes to take effect, we recommend restarting your router.
That’s it! These steps will help improve the screen mirroring quality. If these steps don’t work, you want to check your router’s firmware for updates.
Resetting your router to factory settings can resolve any bugs or glitches that are causing this issue.
This is how to improve screen mirroring quality between your phone and TV.
Now that you know the solutions, you can follow these steps to fix this problem in a few minutes. You don’t have to deal with blurry or buffering videos anymore.
