Thanks for the mention of the UHD service for the Aussie Open. It's also not there for me today. 

1. Is anybody else finding the UHD transmission much darker/having less brightness than the regular HD channel?

2. On the HD channel, is anyone seeing fluctuating frame rates?

Thanks.

hi @NikoBlando 

Just checked and I am able to get the UHD for the current match on Eurosport1

Regarding Darker UHD mode - this might be down to your TV's peak brightness.

SKY UHD channels use a form of HDR called HLG developed partly for live boradcasts  (by the BBC & NHK) but this can type have side effect of reducing brightness - any TV less than around 600 cd/m (aka Nits) may show a noticable (if not unwatchable) image 

What is the make & model of your TV ? 

[NikoBlando]

Thanks a lot for all that detail, appreciated! I have a 2020 43" Samsung Serif.

I'm getting a technical issue code:UHD1 on blue screen after a few seconds when I press the red button for UHD.

1.18.0

But it's always been the case where upgrades & accessories in my sky have always given me errors since installation nearly a year ago. Initially I tried factory reboot but that didn't help.

I don't know if the details I got back are for your specific TV but one search I have for it's peak brightness shows it at 379 nits which is too low really for HLG HDR - Some people can get away with around 500 nits but less than that is likely to become too dark I am afraid

[NikoBlando]

Thanks a lot for looking into that, @nigea99 ! 

Makes sense. I can't see any way to disable HDR in isolation. Oh well. 

have a great weekend.

This has always been something I have been against lot of TVs are sold as HDR but most don't have the screens truly capable of doing it justice and so people got the idea HDR wasn't that good or it just makes things dark.

@NikoBlando  Check the Settings Menu (on most Samsungs should be the following) --> General --> External Devoce Manager --> HDMI UHD Color --> select the relevant HDMI input and remove green dot, this will disable HDR on that input.

[NikoBlando]

That's so helpful, thanks. I only have 'Input Signal Plus' which I understand when off disabled HDR and caps refresh rates at 30Hz. I've therefore inchecked this. 

I'll have to compare another like for like amother time, but the womens' doubles final reply perhaps looks brighter!

[NikoBlando]

Yes, it's like the HD Ready and True HD stickers all over again... Not personally feeling burned as the panels on the Serif are not what I'm prioritising when going for this one, but could imagine some feeling short-changed. 

[Chodley]

I don't think it'll cap the refresh rate at 30Hz. 50 and 60Hz support are mandatory for HDTVs. And the Q can't output 30.

@NikoBlando 

Funny enough that seems pretty accurate yeah it cost me a lot but glad I did the research I did and got an OLED so I could fully benefit from HDR

[Chodley]

His TV probably does an ok job with HDR10, but HLG really doesn't work unless the screen can go much brighter

[NikoBlando]

@CardiffMan1992 
Yeah, the Serif went downstairs to look nice, and it's great for sport etc. but then I got the small LG OLED for upstairs when I actually need to see what's going on in any scenes shot in darkness...

[NikoBlando]

I've never really noticed any HDR effects with either technology, apart from the darkening. The Serif can functionally 'do' HDR, but not to any meaningful extent, to my eyes.

It's right to say that the panel just ain't up to all that. But again, if you're after that, these design pieces aren't (yet) going to get you there. One day they'll put a decent panel in them, then they can take my money in a flash. The LG Objet is a good example of a fair marriage between design and panel, it having a 4K OLED, but it's not as uncompromising as the Serif's look if you ask me, and worse for it.

@Chodley 

Thanks. Got that 30Hz limit thing from here.

Serves me right for believing everything I read on the internet.
