Activate HDR on your TV: enjoy sports with optimum picture quality

Have you purchased a new UHD TV set in the past three years? If so, there is a good chance that you can watch programs in HDR. Activate the function on your TV set to enjoy a clearer picture immediately.


Swisscom TV offers the biggest choice of UHD programmes: on eight channels and including live matches from the Raiffeisen Super League and UEFA Champions League.


Find out more about the type of TV you need here. But before you go and purchase a new TV, check your current set – it might be HDR compatible.




Swisscom TV provides an HDR Assistant to check if your TV is HDR compatible. Follow these instructions:

1. Go to “Settings” in the Swisscom TV menu.
2. Select “System”
3. Go to “UHD/HDR Assistant”
4. Select “HDR Assistant”
5. The HDR Assistant will check if your TV set supports HDR10 or HLG.

To watch programs in HDR, there needs to be a green tick next to “Supports HDR10”. If you see a red cross, run a software update on your TV and check if you need to activate HDR.
You can search for your TV at the following link: This will show all the functions available on your TV set.




For information on how to activate HDR, read the user manual for your TV set. We have summarised some details from a few manufacturers here:

Samsung calls this function HDMI UHD Color. For most TV sets you need to activate it for each HDMI channel. Depending on the TV model, you will find this function in different places in the menu. Older models often list it under Picture settings > Picture options. More recent models list it under General settings > External device management

This function is called HDMI Ultra HD Deep Color on LG TV sets. It is also usually listed under general settings rather than picture settings and needs to be activated for each HDMI channel.

You need to change the HDMI signal format from “standard” to “extended format” or “optimised format” on Sony TV sets. Go to Settings > External inputs> HDMI signal format.

To receive HDR on a Philips TV set, go to Settings > HDMI Ultra HD > HDMI 1&2 > UHD 444/422 or 420.

You need to switch on the HDMI HDR settings on a Panasonic TV as follows: Menu > Setup > HDMI HDR Settings: on

In the case of HDR, the Swisscom TV-Box always uses the settings required by the television. It supports up to 4:2:2 12bit YCbCr. Deep Color needs 4:2:0 10bit and higher as the minimum basis for HDR transmissions on the HDMI interface.

Important: If you have activated the HDR function on your TV, you need to switch the Swisscom TV-Box on and off using the remote control. You may even need to restart the Swisscom TV-Box using the main switch. If you have connected your TV-Box to your TV set using an AV receiver, soundbar or HDMI splitter, this also needs to be UHD HDR compatible. Again, the rule of thumb is: After activation, restart the AV receiver and make sure the software is always up to date.


Picture settings


Once HDR is activated, you can optimise your picture settings. Most TV sets have the option to adjust the picture modes for HDR and SDR separately. Proceed as follows:

• Switch to the HDR channel.
• Select picture settings in the TV set menu.
• Set the required mode or brightness you want.



What is HDR?

HDR incorporates a significantly greater range of colours and contrast, particularly noticeable with very light or very dark content. The greater the luminosity of the TV screen, the greater the effect. If you are watching a channel broadcast in HDR, it is important to realise that the screen will be very bright when you open the Swisscom TV home screen or the TV Guide. When you are not watching an HDR channel, however, the brightness of your TV will be normal. Swisscom is currently working on ways to minimise or resolve this problem.
