Hey guys. Looking for a new tv for the living room. Looking for something somewhat future proof under $1500. Guess we need a hdr / hdmi 2.0a compatible tv? Ready to buy now.

Think I narrowed it down to
Sony xbr55x850c
http://www.rtings.com/tv/reviews/sony/x850cor
Samsung un55ju7100
http://www.rtings.com/tv/reviews/samsung/ju7100

Ideas? Thoughts?
Thanks!

Do you do any gaming? The samsung beats the Sony for that purpose. Also the Samsung JU7100 does not support HDR. Only their SUHD line supports HDR and their wide color gamut. The Sony has a new firmware that unlocks HDR support but it lacks local dimming. The Sony does handle 24p video via a 60p source much better than the Samsung though.

Overall I think it would depend on your usage and what source content you will be using. I can tell you that some of the new UHD TV Shows and movies will look a lot better on the Sony TV simply because it supports HDR, even without local dimming.

Thanks for the reply. No gaming. I have a 4k gaming monitor for that. The tv will strictly be for netflix/amazon prime/dvd's and blu ray movies. I think I'll order the Sony.

FYI, should you step up to the 65" or greater models on the Sony, those do have LED Local Dimming. Sony chose not to do so on the smaller screens, not sure why.

Agreed. Local dimming is worth it. Not to mention at 65" the advantages of 4k might actually be noticeable.

Thanks for the input. I read about the 65"+ having local dimming but the tv was $600 more. I ended up ordering the 55" Sony since it had hdr support, hdmi 2.0a, and interest free financing for 24 months at amazon. Freight delivery Monday

I notice the difference with a 55" screen. It is a complete falsehood IMO to say you need a huge screen to see the difference 4K makes.

Now it does depend on your viewing distance. The further away you sit the larger the screen should be generally speaking.

I have a 55" JS8500 and the difference with 4K is definitely noticeable. Whether or not it's preferable is an open question, but it's certainly noticeable.

the size alone is worth the money... the local dimming is a HUGE factor IMHO...

all that said, I personally think all LCD displays are crap. I would have opted for the 1080p LG Oled if given a price restriction. sure 4K is nice and all, but blacks and contrast far outweigh resolution in terms of PQ...

I have a 55" js9000 and can tell. I would always choose 4K over 1080p given the choice now. No reason not to really. 4K isn't any more expensive than top 1080p TVs were a couple years ago and with UHD Blu-Ray on the way its an easy choice to me. Though I can see where some people are not willing to pay over $1k for a tv and at that point a good 1080p set is going to be better than a low end/off brand 4K set. In that market segment I doubt many would be early adopters of UHD Bly-Ray and the like.

I would take LG's 1080p OLED over any 4K LED set on the market. There isn't enough 4K content, the current consoles can't play 4K games, and OLED is such superior technology for video content it's not even funny. It wins every shootout for a reason.

LG has sold at least three OLED tvs this year just because of my emphatic recommendation. I call it "the iPhone of tvs" to get across the point of its technical superiority to the normals in my life and why they should spend so much more for "just" a 1080p tv.

Have you actually viewed 4K content from a good source? It is a big difference to my eyes and there is quite a bit of 4K content already that I have found. Plus I would not want to invest in 1080p and not be able to use UHD disks if I were buying a new tv today. For me it's investing in something for the future and not only for the sources we have now. If I was interested in OLED I would spend more and go to 4K. I couldn't use OLED in my current set up because I have a wall mount installed that OLED sets are not compatible with. It's really just a personal choice though. I have seen OLED sets in controlled rooms and they are excellent quality but I have not seen them in a home environment in more real world usages. I may have bought a OLED 4K set but there are a few things (input lag for example) that turned me away.

OLED still has growing pains too, it's not perfect. Rtings.com has noted that their LG OLED sets have things like poor uniformity judder in 24p sources etc.

I have seen a couple of nice 4K sets and I have a 4K screen in my kitchen actually. I haven't seen a lot of HDR content though, what I have seen is cool even though I think the brightness is overrated. Honestly for me the biggest "wow" factor of 4K tvs is that GUIs (say Netflixs or Kodi) have really sharp text. I mean a clearer picture during a movie is nice, but when the set lacks the pop and lack of motion blur I have gotten used to with plasmas all the clarity in the world during a still shot doesn't matter.

I have 20/15 vision and I will still take a lower black level over 4K clarity any day of the week. I mean at best 4K is four times as good as 1080p. The black level of OLEDs are MAGNITUDES better than LED tvs. You give a little and get a lot. Edge lit LEDs are complete garbage technology, and no one can afford enough dimming zones in a FALD set to really compete with OLED (or even plasma). It would take thousands of dimming zones, which with today's technology would cost more than OLED.

there is plenty of 4K content already that I have found if you know where to look.

I am about as unscrupulous about attaining content as you can get and what is out on 4K is a drop in the bucket compared to 1080p. I have like 80-ish 4K videos vs over 2000 1080p movies. It will take years for 4K to match the content depth of 1080p and by that point maybe 4K OLED is cheap enough to sneak into this budget range.

That isn't even accounting for the fact that old content really doesn't benefit from 4K like modern content does. Or the fact that with newer content CGI that is believable at 1080p goes right into the uncanny valley at 4K.

Plus I would not want to invest in 1080p and not be able to use UHD disks if I were buying a new tv today.

It we are talking a tv that is over $3K I certainly agree, no reason to not be futureproof especially because they make 4K OLEDs.

If we are talking someone who is buying a sub $2k Tv then they probably don't have the budget for a $2000 PC to play games at 4K, or heck just afford the $35 4K Blu Rays the first couple of years they will be on sale. By the time we see a generation of consoles that can play 4K, or even just get to a point where 4K Blu Rays numbers in the thousands and can be had for $15 normal price like Blu Rays, it will be time to replace a sub-$2k tv probably.

OLED still has growing pains too, it's not perfect. Rtings.com has noted that their LG OLED sets have things like poor uniformity judder in 24p sources etc.

Sure sure. It kinda sucks that only LG makes them because their video processing is garbage and always has been. Firmware updates have helped the uniformity issue though on the top model. Their OLED sets aren't perfect, and if I had one I would jump through hoops with MadVR to get around the limitations. If Panasonic made an OLED for our market I would be much happier.

But jeez, they are just SO much better on the one metric that matters more than any for video content (contrast ratio) I couldn't even consider spending any money on the inferior technology that is LED. A dark movie like Gravity or Star Wars is a whole nother ballgame on those beauties.

It is like if Intel came out with a CPU that was the equivalent of whatever 2020's i7 will be, but you can only use it to play games (not even web browsing) and it's twice as much. Many gamers would sign up for that in a heartbeat. That is the kind of gap we are talking about. This isn't VHS vs Betamax, this is Betamax vs a Blu Ray.

I get that you are more of a gamer though, and you obviously are willing to throw the hardware at the screen needed to play in 4k. In your shoes I would probably have a 4K LED as well. People have different priorities in life. I am videophile myself.

At least we are on the same page. I see 20/10 and everything in 4K was just better to my eyes. I actually had a plasma that my 4K set replaced. It has severe issues with the picture and had to be replaced. No the blacks on the new set aren't as good as when my plasma was working but they aren't bad and honestly the 4K and HDR is really incredible to me. Maybe I am a sucker for brightness.

Many people are, nothing wrong with that. Heck that fact killed plasma, and is the reason the expensive tvs are run in dynamic mode at best buy. I actually don't run my newest plasma as bright as it can get, and I don't do a lot of daytime watching.

OLEDs won't have gsync or freesync or anything like that for a while. For gaming LED has clear clear advantages.
