How to know if your TV supports the new 4K DTT channels starting November 5

The new 4K DTT channels use the DVB-T2 system and HEVC codec, essential to receive and watch them properly. On November 5 at 8:00, this change begins, directly affecting how to access Digital Terrestrial Television (DTT).

The channel La Séptima, although new, does not require this technology because it broadcasts in HD, but it will be necessary to retune the DTT to find it and to adapt to the changes in channel positions.

What exactly changes on November 5?

Which channels arrive in 4K and what does this imply?

The channels La 1 UHD, La 2 UHD, Antena 3 UHD, and Telecinco UHD will start broadcasting in 4K resolution (Ultra High Definition) using the DVB-T2 system and the HEVC or H.265 codec. This means they can only be viewed on televisions compatible with these standards.

How do the position changes and the new channel La Séptima affect you?

Some channels will change their location within the DTT dial, so it is essential to retune the TV to avoid losing any channel. La Séptima is a new broadcaster that transmits in HD and does not require DVB-T2, but it also requires retuning.

How to know if your TV is compatible?

What requirements must your TV meet to watch the 4K channels?

Only a TV with support for DVB-T2 and the HEVC codec will allow receiving and playing the new 4K channels. Neither being a Smart TV nor having a 4K screen guarantees this compatibility.

How can you verify your TV’s compatibility?

The simplest way, although not always practical, is to check your model’s technical sheet, looking for the terms "DVB-T2" and "HEVC" in the settings or on the manufacturer’s website. Usually, TVs manufactured from 2017 onwards incorporate this technology.

A very direct test is to retune the DTT and check if the channel La 1 UHD appears. If you have it, it means your equipment is compatible, and you will be able to watch the rest of the 4K channels without problems.

What to do if your TV is not compatible?

What options do you have to keep watching the new channels?

If your TV does not support DVB-T2 with HEVC, you have two alternatives: buy a new compatible TV or acquire an external decoder that handles receiving this new signal. The second option is usually more economical.

Is it always necessary to retune the DTT after the change?

Yes, necessarily. After November 5, you will have to retune the DTT to update the channel list, including the new channel La Séptima and the channels that change position.

• Access the Settings or Channel Settings menu on your TV.
• Select the Retune or Search channels option.
• Wait for the process to finish and verify that La 1 UHD appears.
• If it does not, confirm compatibility with DVB-T2 and HEVC.

How to check if you are affected?

• Is your TV less than 9 years old? It is probably compatible.
• After retuning, does the channel La 1 UHD appear? You are ready for the new 4K DTT.
• Do the 4K channels’ images show lower quality or do not appear? Your TV is not compatible.
• Do you have a decoder compatible with DVB-T2 and HEVC connected? You will be able to watch the channels without buying a new TV.

To maintain an optimal experience, it is recommended to keep the TV or decoder updated, activate automatic updates if possible, and perform periodic reviews of permissions and connections. Technical support can help if you detect problems after the change.

One detail often forgotten is to make backup copies of the configuration or preferences on devices with this option, to avoid losses after a retune or update.

The reality is that preparing for the new 4K DTT guarantees that you won’t miss any channels and that you will enjoy the best image quality available. Don’t get left behind: check compatibility now and prepare your equipment for this technological leap.
