TV box picture quality can no longer be adjusted

Hello everyone

For some time now I have not been able to change the image quality in the menu.

This point is no longer listed at all.

Even if I press options, the quality cannot be selected (gray instead of black).

I have restarted and reset many times.

This is very important for me because I can only use HbbTV in medium quality.

This is because we don’t have the best signals here.

I’ve contacted support so many times that I don’t want to call them anymore.

Maybe someone has had this problem before and has a tip for me.

If it works in each case, then it works for all channels that have HbbTV.

Or then not at all.

Many thanks to those who answer me.

Assume reset with the paper clip?

What speed do you have on site and is the TV-Box connected to the Internet box via LAN?

Use the link below to call up the status menu of the Internet box and then use the mouse to press the top green dot on the right, image pattern below.

Hello Walter

The box is connected via WiFi, the TV is not in the same room.

We have a weak connection.

I just did a speed test this morning and it showed me 7 to 2.

It’s never been better, and it worked very well for a long time.

Do you think I can’t change the quality because of performance?

I find it strange that this menu item is suddenly missing.

@Faummoplie89

I can’t say whether the performance of the menu changes anything, but do you have the possibility to test connect the TV-Box to the Internet box with a long LAN cable?

Have you connected the TV-Box to a WLAN-Box and this then establishes the connection to the Internet box, I have used this variant for some users where the TV-Box is connected to the Internet box through a wall or ceiling, the own WLAN from the TV-Box is not as good as the connection via the WLAN-Box.

How many obstacles are there between the TV-Box and the Internet box?

@Faummoplie89 Can you please put a photo in if you clicked on the menu item “Video and Audio” in the settings? So where the menu item Image Quality should be.

For information, please note the TV box version

With such a slow internet connection, you would probably have to set it to SD anyway if you connected the TV box via WiFi.

In your case I would consider a wired solution, this is somehow feasible in most cases.

Hello @Faummoplie89

As @WalterB wrote, I would connect a flying cable. And see if it works.

What do you mean by 7 to 2?
7Mbit download? Of course that is already at the limit. An HD stream quickly needs 8 Mbit. I don’t know whether the system will say no. Possibly Swisscom made some changes to the firmware.

What does the Checker output?

Faummoplie89 · Jun 25, 2023

Yes, that is very little.

That’s why I want to adjust the quality myself. I suspect that it is too high and that it is not suitable for interactive television.

Nothing more on it.

Image quality for the apps refers to Netflix etc.

roku73 · Jun 25, 2023

@Faummoplie89 What picture quality is displayed on the TV channels when you select the picture quality option? Depending on the transmitter, 1-2 variants should be included.

As it looks here, only SD is possible and therefore the menu item has disappeared in the settings.

Faummoplie89 · Jun 25, 2023

Thank you all for the quick replies.

I can try with cable later.

Let me know what it looks like.

WalterB · Jun 25, 2023

@Faummoplie89

According to Checker, what would be available to you at the link below?

WalterB

According to Checker, I don’t have any internet at all.

Faummoplie89 · Jun 25, 2023

This item no longer exists in my menu.

And I can’t select it under options because it’s gray instead of black.

I had set it up via the menu, but there hasn’t been anything there for a while now.

Faummoplie89 · Jun 25, 2023

I just reset the box and re-set it up with the cable.

Unfortunately this makes no difference.

Strangely enough, I never had and still have problems with the apps.

I can watch Netflix and YouTube really well.

I don’t have any interruptions when watching TV either.

I think I’ll have to try support again.

I once asked a gentleman what he did when it worked.

I then wrote down the date that he had set the signal-to-noise ratio.

Unfortunately, the next employee had no idea what that was.

I’m giving up for today.

Thank you very much for all the advice and help

have a nice Sunday

Best regards

@Faummoplie89 the SC employee has to set the SNR (Noise Margin) to (-) 6dB.

But it’s just symptom relief.

The support staff (2nd level) can see the errors on your Anschluss.

The system stabilizes the line if there are too many errors on your telephone/DSL Anschluss.

The maxim is to keep the connection line stable, the SNR is regulated up to (-) 24dB.

This affects your router access speed and therefore also your TV stream bandwidth.

From 8 Mbit/s only SD is possible

SD or HD is possible from 12 Mbit/s

SD or HD or UHD is possible from 40 Mbit/s.

Simile: Your water pipe in the garden keeps having interruptions in the water flow. In order to reduce these interruptions, I reduce the water pressure so that there is an even water flow.

So I would order a technician to check your connection cable.

If the error is in your in-house telephone installation, it costs CHF 160 per hour and a travel fee of CHF 80.

Otherwise, if the error is on the Swisscom side (from UP/GS-> Central/PUS/MCAN) it costs nothing.

Thank you, I’ll have to do that.

Otherwise I probably won’t get rid of the problem.

Thank you for the detailed answer. Very nice.

Best regards
