Pixelated on black screens

Herm4n — Thu, 11 Sep 2025 16:09:04 GMT

Hi, I've recently got sky glass tv and on the black screens it very pixelated. I also have a puck in another room which is on a normal Panasonic tv and it does not have the same issue. Are sky glass tv' s just poor quality?which is strange as sky offer UHD, but down have a TV to match. By the way my broadband on WiFi is 560mbps, which shouldn't be an issue as the black screens on the puck on the Panasonic tv is ok. Thanks

It's largely down to the type of panel and backlighting that Sky have chosen to use on Glass.

Sky Glass uses an LED backlit VA type LCD panel. Glass gen2 has local dimming, Glass Air has global dimming. Depending on the picture mode you are viewing in, the image quality can vary quite dramatically. Dark scenes with a lot of black on them can suffer, particularly on Glass Air, as the backight will show up any compression artefacts more readily.

You'll get slightly better results by watching content that is less compressed, such as from a 4K BluRay disc connected to the TV, but there's nothing you can really do about Sky's own content other than have a fiddle with the backlight and picture settings to see if you can get it to improve.

Your other Panasonic TV has perhaps got a better local dimming algorithm so doesn't show up the compression artefacts as much, or, if it's an OLED type TV then it will handle blacks a lot better.

Ben,

Many thanks for that explanation. Unfortunately when I rang sky about it, they told me that's unusual and they don't get many people complaining about that, that's why I decided to come on here and ask people who are not paid by sky to say so. Luckily I'm still in my cool down period so can still decide to return the equipment.

Thanks again.

I had pixilation issues on our new Air TV bought Dec 25 and complained to Sky. Who, took me through a list of actions (including upgrading to UHD), none of which resolved the issue, asked for photos of the issue on the screen. As a result, they provided a replacement Air TV which I have had now for just 3 days. The issue however, remains, despite me reducing the backlighting setting. Considering either upgrading to Gen 2 version, which suggests better picture resolution, but £22 p/month extra! Or, purchasing a non Sky TV.

Any suggestions on replacement TV?

It has been suggested I switch from WiFi (tv states signal very strong, paying for 500 mbps though getting closer to 40/50 mbps) on full fibre, to ethernet cable! Anybody done this, and if so what was the outcome? Would it effect my viewing with sky pucks in other rooms?

I have the same problem, sky sent an engineer round to supply and fit a Ethernet cable, made no difference at all, he said it's because these ty's are for uhd, my 2 tv's running off pucks are fine, this has been the worst thing sky has ever supplied its not fit for purpose
