UHD 4K material and UHD Alliance definations - HDR - KD55X8505C

[Merlins_Apprentice]

Hi 

Im trying to understand this new approch from UHD alliance and what impact it will have on UHD TV's from 2015! Like the one i just bought KD55X8505C ?

Until now there is not much 4K material around to enyoy so I thought I was a little step ahead of things when bying this TV. Will it allready be outdated before the real 4K materials comes alive!

There are no 4K movies to buy and no way to play them yet if there was!

The only options now as I see it is streaming from Youtube and Netflix. 

If you have a 4K video recorder like a Sony Xperia phone with 4K then you also should be able to view it in 4K on the TV, but i read in another post here that you can not stream 4K over DLNA on Sony TV, so how then?

Hi there

Only 1 2015 Bravia TV  meets the "Ultra HD Premium" label criteria, it's the 75X9405C  which is....a Full Array LED backlighting.

Barring in mind that 'premium' sets the bar quite high.

"If you have a 4K video recorder like a Sony Xperia phone with 4K then you also should be able to view it in 4K on the TV, but i read in another post here that you can not stream 4K over DLNA on Sony TV, so how then? "

MHL cable from phone to TV or you can dump your 4k recordings to a PC or laptop that's capable of outputting 4k and use something like the excellent freeware Pot Player or Media Player Classic to play your 4k footage back.

True HDR is only capable on a Full Area Local Dimming set, which usually cost like £1000 more than your TV, but you will still get a lot of the benefits of HDR like better colour gamut and the rec BT2020 colour profile.

Even "Faux" HDR looks great I've been using it to play Grand Theft Auto 5 on PC@4k60fps. It looks amazing on that game specifically. If anyone here knows what "ENB" or "Sweetfx" is for pc gaming, then HDR reminds me of both of them, without the performance hit.
