HDR & UHD for your blue TV: what you need to know

UHD offers a higher number of pixels; HDR greatly improves contrast and has a much broader colour spectrum. In combination, the two technologies deliver a noticeable improvement in quality. With blue TV, you can enjoy a range of channels and programmes in HDR and UHD. All you need is the right setup. 

 

In order to receive UHD and HDR, you will need a UHD-compatible TV-Box from Swisscom as well as a UHD-/HDR-compatible TV set. Find out now whether you have the equipment you need: 

  1. Press the home button on your blue TV remote control and select the cogwheel in the top right. 
  2. Choose Video & Audio 
  3. Go to UHD > the status of your connected equipment is indicated by a green tick or red cross. 
  4. Go to HDR 
  5. Choose the HDR-Test tab 
  6. This test detects whether your TV supports HLG, HDR10 and/or Dolby Vision.  

To watch 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. See below for more information. 

 

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. 

 

Activating HDR 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 

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. 

 

LG  

LG calls this function HDMI Ultra HD Deep Color. It is also usually listed under general settings rather than picture settings and needs to be activated for each HDMI channel. 

 

Sony 

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. 

 

Philips 

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

 

Panasonic 

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 TV-Box from Swisscom 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 blue TV on and off. You may even need to restart the TV-Box (if present) using the main switch.  

 

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 better the effect.  

 

HDR10, HDR 10+ or Dolby Vision? 

There are a number of competing HDR standards at the present time: the widely used HDR10; Samsung's HDR10+; HLG, a format co-developed by the BBC and primarily used for live programming, and ‘Dolby Vision’, promoted by LG and also used by Netflix and Apple TV.

The Swisscom Box from blue TV conforms to all the different standards and is fully compatible with the latest generation of televisions, which can typically display more than one standard without a problem. It is even the first box of its kind in Europe to support Dolby Vision. Worth knowing: Dolby Vision, like HDR10+, is one of the next-generation HDR standards, offering an even better HDR display than the widely used and somewhat older HDR10 standard (without the plus). 

 

These standards are rarely specified directly on the visible logos on the screen. If in doubt, therefore, it is vital to check with the retailer of the device in question.

I activated my TV’s HDR setting, I turned the Swisscom box on and off, it says the output is 3840x2160 but I still do not see RTS Deux in UHD, just in HD (I know because the logo is different) 

 

i have a TV L and internet S at 40 Mbit/s package

Hello @Etoledo

 

It seems that you don't own the new UHD TV-Box: https://bit.ly/2zf5c8L

@LeylaGI investigated the problem further and, whilst I do actually have a UHD TV Box, my area's internet connection is not good enough for UHD (capping out at 30 MBit/s and not 33 as needed) but thank you for the response!

@Etoledo You're welcome! Thanks for the feedback. I hope an improvement of the network will be possible soon at your address.

I have an HD TV set but an iPhone XS max + iPad with Retina display.  If I subscribe to teleclub will I be able to watch the UHD programs on my iDevices or not? (I am rarely in front of my TV which is why I have not yet upgraded)

Hello @AzimA

 

The UHD programs are only available on a TV screen.

Is there any restriction regarding the picture / sound quality when using the blue TV app on a smart tv (supporting UHD / 4k)?
The only information I found (https://www.swisscom.ch/de/privatkunden/abos-tarife/inone-home/swisscom-blue-tv/geraete.html) indicates that 4K, UHD, HDR, Dolby Audio will only be available when using the Swisscom Box.

Hello @leo-bruder

 

As far as I know, there are no further sound/image restrictions while using blue TV app on a Smart TV. However, some features like the voice assistant or the access to Netflix and Amazon Prime are not available.
