QR Code on TV: How to Scan It and Why It Sometimes Does Not Work

To scan a QR code on a TV, open your phone's Camera app or Google Lens and point it at the code on the screen. If it will not scan, the cause is usually glare, brightness, distance, focus or an expired code, not a broken code.

Dim nearby lights, turn up the screen brightness, and move closer or further away until the whole code is sharp and fills a good part of the frame. If a login or pairing code has expired, refresh it on the TV and scan the new one.

How to Scan a QR Code on TV

A QR code on a TV scans the same way as any other QR code. For every method in detail, including scanning from a photo, see our guide on how to scan a QR code on iPhone and Android.

• iPhone: Open the Camera app and hold your iPhone so the QR code appears. Then tap the link that appears. Control Center also has a Scan Code button.
• Android (Pixel): Open the Camera app, point it so the whole square is on screen, and tap the bubble or link that appears. Quick Settings has a Scan QR code tile. Google Lens also works.

Hold your phone steady and keep the whole code inside the frame. If your lens is smudged, wipe it with a soft cloth.

Why a TV QR Code May Not Scan

Most failures come from the room, the screen or the code, not from the phone.

• Glare and reflections: Glare from windows or lamps can wash out the code. Dim nearby lights, close the curtains, or scan from a slight angle so reflections miss the code.
• Brightness: A dim screen makes the code hard to read. Turn the brightness up and turn off glare-reducing or dimming filters if you can.
• Distance: Standing too close can show the screen's pixel pattern as a shimmering effect that confuses the camera. On a very large TV you may need to step back further than feels natural. If the code is small in a corner of the screen, move closer.
• Focus: Give the camera a moment to focus before you tap.
• An expired code: Some TV apps show a login or pairing code for a limited time. If it has expired, refresh the code on the TV and scan the new one.

What TV QR Codes Are Used For

QR codes on a smart TV are often used for logging in to an app or pairing a device, or to open a link shown in an advert or programme. The code opens whatever link its creator chose.

Before you open a link from a TV QR code

1. Look at the link preview your phone shows before you open it.
2. Do not enter passwords or payment details on a page you reached from a code you do not trust.

Tips for Showing a QR Code on Screen

If you are putting a QR code on a screen yourself, a few things help viewers scan it.

• Leave a blank margin. Denso Wave, the inventor of the QR code, says a QR code needs a four-module wide margin on all sides.
• Use strong contrast. A dark code on a light background is the safest choice.
• Make it big enough and keep it on screen long enough for people to point a phone at it without rushing.
• Link to a short web address or a mobile-friendly page.

Backup Method: Scan a Photo of the TV Screen

If live scanning keeps failing, take a clear photo of the TV screen and scan the code from the photo.

1. Take the photo straight-on so there is less glare and distortion.
2. Open the photo in your Photos app or in Google Lens.
3. Use it to read the QR code.

This can work when the code is hard to scan live. It is a backup, not a first choice.
