UHD

[Burntplumz]

I have a new 65" 4k/uhd, hdr tv.  Everything is great including my PS 5, BUT anything in sky uhd is so so dull and lifeless. In fact sky uhd spoils the veiwing, i am always reverting back to normal hd which is so vibrant and colourful compared to uhd.

my tv set is ok as i have checked and rechecked, all streaming services that offer 4k are great, my PS 5 is great too. Its just sky q uhd..... after all the tv ads i find it such a let down at the moment.

Any ideas ?

Are you watching UHD content on Sky that has HDR? Not all TVs cope with HLG, the type of HDR that Sky uses for it's live UHD HDR sports content and all downloadable/streamed UHD HDR content. 

Have you tried just watching any standard dynamic range UHD Sky content on your TV? Give that a go and see if it improves.

The other thing to note is that your TV when it detects a HLG HDR UHD signal from Sky, should automatically switch to an HDR picture preset. It may just be that you need to tweak this preset using the picture settings menu on your TV whilst playing some HLG HDR UHD content and see if you can get it looking like you want it to.

It mainly applies to live sport rtc thats broadcast in uhd, for example yesterday with the F1 and football i had to watch it on the alternative hd channel.

i have also noticed that non sport und programmes, are fine...BUT in scenes that are darker, i get quiet a grainy effect.

Will try and adjust the tv picture settings, but according to the sky hdr test card everything is set fine.

Hi @Burntplumz 

You need to see what the Peak Brightness is for your TV.

You really need at least 600 nits to get an acceptable experience with HLG HDR.

@Burntplumz what make and model of TV is this with 

[Burntplumz]

Im not sure how many nits my tv is to be honest, how  could i find out ? My tv's 4k/uhd hdr is fine with eveything that isnt sky.

[Burntplumz]

My tv is hisense, cost me just over £800. Everything non sky uhd hdr is fine. Just so annoyed that sky advertise all this clarity etc and its turned out out to be dire so far.

Do you know the exact model number? Normally if HDR looks dull or too dark it's because the TV can't reach the level of peak brightness required.

Hi @Burntplumz   From the evidence so far I would change the UHD to 8 bit. It appears that your TV is not switching to HDR or cannot handle HLG. 8 bit should be a lot brighter without HDR.

Even though £800 is a lot of money, for a 65 inch tv it is relatively cheap, so unfortunately you won't get a great experience watching HDR content. @Burntplumz

@Burntplumz   If your new set can only achieve a peak level of around 600 nits, when attempting to display a HDR, HLG image it will be limited to achieving a nominal Reference White level around 143 nits.

But, I regularly find that quite a large proportion of people are using a nominal Reference White level of around 200 nits when they are viewing HD material, which makes them immediately aware of having a rather dim HDR, HLG image if their display screen cannot provide the peak luminance required to allow their HDR, HLG nominal Reference  White level to match the nominal 200 nit Reference White level of their HD images.

So, my personal advice has always been to purchase a television that can achieve around at least 850 nits, if your preference is to have a relatively bright HD display image calibration, and it will not be having the benefit of the extended black levels available from OLED display panels.
