Starting today, Spain's digital terrestrial television (TDT) begins its first phase of the jump to ultra-high-definition (UHD), requiring viewers to rescan their televisions to access new channels and frequencies. Unlike the 2024 HD blackout, no channels disappear, but several new UHD channels and the launch of La Séptima mean you'll need to retune your TV to keep watching.
What's changing on TDT today?
Today, November 5, 2026, marks the first phase of the transition to DVB-T2, a standard that allows for UHD broadcasts. The state-owned multiplex RGE2 will begin using DVB-T2 to deliver UHD content, while other multiplexes continue as before. This means some channels are moving to new frequencies, and new channels are being added.

Importantly, no channels are being removed. The shift is purely technical, aimed at improving picture quality and enabling UHD. However, not everyone will be able to watch the new UHD channels, as they require compatible equipment.
How to rescan your TV to watch new channels
To continue watching all available channels, including the new UHD ones and La Séptima, you must rescan your TV or set-top box. The process is straightforward and varies slightly by manufacturer.
- Press the Menu button on your remote.
- Go to Settings or Installation.
- Select Channel Search or Auto-tuning.
- Choose Antenna or Terrestrial as the input.
- Start the scan and wait for it to complete.
- Save the new channel list when prompted.
After rescanning, you may need to reorder channels or update your favorites list. If you use a external tuner or a TV with built-in DVB-T2, the process is similar.
New UHD channels and La Séptima
The first phase introduces several UHD channels, but availability depends on your TV's capabilities. To watch UHD, your TV must support DVB-T2 and the HEVC/H.265 codec. Most TVs sold after 2016 include these, but older models may not.
La Séptima is a new channel launching today. It will be available in HD and will be accessible after rescanning. The UHD channels will only appear if your equipment is compatible.
Will you be able to watch UHD? Check your TV's compatibility
Not all viewers will receive the UHD channels. Your TV or set-top box must support DVB-T2 and HEVC. Here's a quick comparison of what you need: Context on how this played out before sits in TDT Resintonización: How to Watch New UHD Channels and La Séptima.
| Feature | Required for UHD | Required for HD |
|---|---|---|
| DVB-T2 tuner | Yes | No (DVB-T works) |
| HEVC/H.265 codec | Yes | No (H.264 works) |
| UHD resolution (3840x2160) | Yes | No (1080p is fine) |
| HDMI 2.0 or higher | Recommended | Not required |
If your TV lacks these, you can still watch HD channels, including La Séptima, but not the UHD ones. Consider an external DVB-T2 set-top box if you want UHD without buying a new TV.

What to do if you can't find the new channels
If after rescanning you still miss channels, check your antenna and cables. Sometimes a weak signal prevents new frequencies from being detected. Also, ensure your TV's firmware is up to date. If problems persist, consult your TV manual or contact the manufacturer. Earlier coverage in Bending Spoons: Italian Tech Giant Winning Wall Street by Buying Failing shows how the argument developed.

For those with community antennas, building administrators may need to adjust the installation to receive the new multiplex. In that case, contact your building's management.
