How to Check if Your TV Supports New 4K DTT Channels from November 2026

If you want to know how to check if your TV supports the new 4K DTT channels launching on November 5, you're in the right place. On that day, Spain's Digital Terrestrial Television (DTT) will undergo one of its biggest technical changes in over a decade, with the arrival of the first 4K (UHD) channels using DVB-T2 technology.

This shift brings new channels that require the DVB-T2 standard, while others will remain accessible without it. You'll also need to rescan your DTT to receive all the new services. It can be confusing, so we'll break it down simply.

What's Changing on November 5?

The major DTT change will take place on November 5 starting at 8:00. From that time, several changes will occur, including the launch of new 4K channels and the reorganization of existing ones. The technical shift that could leave your TV outdated only affects your ability to watch the 4K channels.

The fact that La1, La2, Antena 3, and Telecinco will broadcast in this resolution does not mean the HD channels will disappear. You won't lose them; you simply won't be able to watch them in maximum resolution if your TV isn't compatible.

Why Your Smart TV or 4K Resolution Isn't Enough

Having a Smart TV or a 4K resolution doesn't guarantee compatibility with the new 4K channels. To watch them, your TV must support the DVB-T2 standard and be compatible with the HEVC (H.265) codec.

DVB-T2 is the second generation of the digital terrestrial television standard, allowing more efficient transmission and higher capacity, which is necessary for 4K broadcasts. HEVC is a video compression standard that reduces the file size of high-resolution video without losing quality, making it possible to broadcast 4K over the air.

Key Compatibility Requirements

• DVB-T2 tuner: Your TV must have a built-in DVB-T2 tuner or you need an external set-top box that supports it.
• HEVC (H.265) codec support: The TV must be able to decode HEVC video.
• 4K resolution: While not strictly required to receive the channels, you need a 4K TV to actually see the 4K picture.
• Firmware updates: Some TVs may require a software update to enable DVB-T2 or HEVC support.
• Rescanning: After November 5, you must rescan your TV's channels to pick up the new services.

How to Check If Your TV Is Compatible

To find out if your TV is compatible, start by checking the manufacturer's specifications. Look for mentions of DVB-T2 and HEVC in the user manual or on the box. You can also check the TV's menu system for a section on tuner settings or signal information.

Another way is to use online tools or contact the manufacturer's customer support with your TV model number. They can confirm whether your TV supports the necessary standards.

Step-by-Step Compatibility Check

Follow these steps to verify your TV's compatibility:

If your TV lacks DVB-T2 or HEVC support, you can still watch the new 4K channels by purchasing an external DVB-T2 receiver that supports HEVC. These set-top boxes are available from electronics retailers and are relatively inexpensive.

What Happens If Your TV Isn't Compatible?

If your TV isn't compatible, you won't be able to watch the 4K channels in maximum resolution. However, you'll still be able to watch the HD versions of those channels, as they will continue to broadcast. The change only affects the 4K transmissions.

To avoid losing access to the 4K content, consider upgrading to a compatible TV or buying an external receiver.
