DirecTV 4K is worthless. Don't do it.

Can we talk about TVs too? Do I have to buy a $1000+ 4K TV or will the $400 Samsung do the same thing--I mean, 4K is 4K right?

What are you looking at? Vizio has some great 4k TVs out that are under $1000.

Sounds like he has a 4K, just not a super expensive one...at least that's how I read it.

From what I've read, size is more important than price.

4k on under 50in is a negligible difference between 1080

If you're not an AV nerd, then yes. I'm on the AV nerd side. My old 1080p Samsung plasma broke about a year ago and I wanted a 4k plasma but they don't make them anymore. I got a middle of the road, cheaper LG 4k TV.

On a dark scene in a movie, with a section of the screen with white in it, I would see these columns of white vertically on screen. It's based on how the LED's light the screen. Local Dimming I believe is what it's called.

The cheaper LED's have this pretty badly and you can't really do anything about it. If you don't notice or care, go for it. I ended up getting the best non OLED screen I could afford. It still happens, but it's far less noticeable.

I predict OLED screens will start coming down in price in the next year or 2.

Example of the Local Dimming:

Example of the Local Dimming:

Local dimming actually refers to zones of led's that can be turned on and off to give better dark sections when needed. More local dimming zones are usually better. The other mainstream option on LEDs is edge-lit, which is worse since the whole LCD panel is lit by <usually> LEDs on the edge of the LCD Panel.

A decent explanation is in the article your pictures came from.

I kind of think HDR is more impressive than the resolution.

"Tales by Light" on Netflix it pretty cool.

www.rtings.com has some really good info. It has the "best of" in different budgets.

I picked up a Samsung KS8000 55" last winter and love it. Both the picture and form factor are great. Around the edges it's less than an inch thick.

Yes. HDR is actually all that matters unless you've got your nose up against your 50" TV. Sitting 6-8' away on your couch, the vast majority of people with normal or corrected eyesight can't distinguish much of a difference between a 4K or 1080P resolution.. but an HDR 720p scene would look more impressive to most than a 4k SDR scene.

I'm not saying that 4k doesn't matter. It absolutely does improve picture quality and we can see a difference from the couch, but it's not nearly the difference that having more life-like contrast ratios and color gamut is.

When you're standing 2' from the TVs at the store, the 4K TVs look wildly better, even the 48"ers.. but you're not going to want to buy a 48" 4k TV unless you plan to sit right next to it at home. At home, you really want that 65"+ 4k TV to take advantage of the extra pixels from a normal sitting distance.

That's not to say that the HDR10 presentation is bad, it isn't at all...it's actually rather good, but the DV presentation has more shadow detail and better highlights making for a fuller looking image.

I will say that the uncompressed audio on the UHD curb stomps the streaming version, though. Pacific Rim is a home theater audio showcase disk. Your neighbors will hate you if watched at high volume.
I just put together this stand for my new TV since my old plasma is mounted to a spine, for lack of a better word, on my old stand which I'm moving out of the living room. A decent Atmos setup will be next on the list.

After much researching I went with the Vizio P-series 55". Some reviews don't like the tablet remote; however I really enjoy it. For around 1k you cant go wrong. Picture is fantastic - zero complains for the price. IMHO Its actually better in many situations than the Panasonic OLED my father got at around the same time. The only drawback is that the tablet is chromecast based, so you can't cast AmazonPrime (as of now) via the tablet. For me, this isn't a problem since I can use firestick or PSPro, but for those without any additional devices it would be an issue

In "many" situations? No. Put them side by side in a dark room and prepare to be embarrassed.

In really bright daylight is the ONLY situation that I can imagine where it may have the slightest edge.

I have a local dimming Vizio set (M-series 75") and a 65" LG OLED, and it's not even close.

The P series has 128 local dimming zones to the M's 32.
