Basic Question: 4K v UHD v HDR

[ScarredLungs]

I am not informed on new TV's and the new acronyms and what is needed etc. If there is a thread that talks about this, just link below and we can close this one.

I have seen that some PS4 games utilize HDR for better looking games. I also see some 4K blurays mention UHD on the cover.

4K v UHD v HDR?

1. Is UHD the same thing as 4k?
2. Is HDR technology a benefit of 4k, and thus on all 4K TV's or is HDR only on select TV's
3. I am looking to get an upgrade my current 55inch with a 4k (HDR?) TV. Recommendations?
4. What else should I consider when buying a new 4K TV?

[Jompa]

1. Ultra HD. Yes.
2. No, not on all TV, but most newer 4k tv's i think
4, 5.1 sound or better is good. It makes most films more enjoyable.

Usually I would say an good mid-range TV is the Sony 55" 900F for $1299 at BB. It supports 4K with HDR (HDR10/Dolby Vision), but please note the OLED55B7A at bottom, right now that is a STEAL!

see sony 900f review rtings
also see LG OLED55B7A


UHD or 4K describes 2160P resolution in a TV
HDR/WCG is part of 4K TV specs
Usually the interface, operation, number of ports in case you want to connect other things to it like a BD player/AVR or a soundbar or other HDMI device.


Alternatives Budget TV 55" would be the TCL P series 615/617 for $599. (the 65" is what most get of this TV)
Better TV would be LG OLED OLED55B7A (last years) going for $1499
current model the OLED55B8 is $2299

Ya, right now I would be shopping for a budget 4k TV with HDR.

See the TCL P series rtings then, the 65 is more useful then the 55, but build in speakers are so so.

Good to know! Thanks.

Intriguing, as I don’t think I’ve ever seen an avatar like yours on any audiovideo forum. Is that asymmetrical tracheobronchial tree of the left lung a video artifact or due to some pathology?

As to your shopping venture, I’ll only offer some general advice to always keep in mind…

Very True. Although I am on a budget, it is ideal to keep it around $1000. That may mean I wait until black friday and see if I can grab something then. I have an older 55inch TV and I would like my next one to be a 4k.

From it seems, I need to ensure that I get a 4k TV that uses HDR.

As far as my avatar goes, I use that avatar found via a google search just because. As far as my name, that is referencing my Single Bilateral Lung Transplant (aka - Double Lung Transplant)

Robert, offer the man a deal on somethin, as he’s already earned it in life. If nothing else, it would be good (and deserved) PR for VE.

[ScarredLungs]

I stopped by Walmart since it was on my way home. Don't TVs said HDR and others said Active HDR. If the word active strictly for marketing purposes?

[nick4Knight]

Active is what LG's OLEDS do... they turn static meta-data (HDR10) into a dynamically processed version.

Many OLED users report it makes their regular HDR10 movies (75-80% of titles released on disc) look better for the HDR image. It's the tone-mapping that it works on.

• Technically, 4K is actually 4096 pixels horizontally multiplied by 2160 pixels vertically. However, this resolution was created for cinema/ theatrical presentations and does not match the aspect ratio of most television presentations. Therefore, a slightly lower resolution called Ultra High Definition (UHD), which equals 3840 pixels horizontally multiplied by 2160 pixels vertically, has been developed. Despite this difference, the term "4K" has become synonymous with UHD even though it is actually slightly higher.
• High Dynamic Range, known commonly as HDR, refers to a much higher level of luminous contrast (i.e. the difference between the bright and dark portions of an image) relative to Standard Dynamic Range. It is not an inherent characteristic of 4K / UHD, because it can be incorporated into lower resolutions. However, it is included exclusively with 4K / UHD for marketing purposes; if it were included with lower resolutions, people would be less likely to adopt 4K / UHD technology, because even though 4K / UHD is higher than Full HD (1080p), a lot of people cannot perceive the difference between it and 4K on screens that are smaller than 100". The following is a video about HDR:
  HDR As Fast As Possible
• Pretty much every UHD television includes HDR nowadays; only the first few generations of UHD televisions did not include it.
• There is also another display technology that is included exclusively with 4K / UHD and it is known as Wide Color Gamut. It refers to a greater range of colors relative to that included with lower resolutions; this greater range of colors encompasses the color spaces DCI-P3 and Rec. 2020.
• As for which TV you should get, considering your budget of $1000, a model from Vizio's 2018 P-Series or TCL's 2018 6 Series, which consist of LED LCD televisions, would be a good choice, as it would feature high-level specifications, such as high peak brightness levels, as well as local dimming for adequately dark black levels, which are fundamental in regard to experiencing HDR. In case you're not aware of what local dimming is, it is the ability of a TV to turn off certain portions of its backlight while leaving others on so that true blacks can be displayed in the same frame as very bright colors or even perfect white, which results in a very high contrast level. The efficacy of this technology depends on the number of local dimming zones per unit area of a screen's size and the algorithm via which a TV controls the zones.
• On the other hand, if you're considering an OLED television, you should keep in mind that even though OLEDs sport much richer colors than their LED LCD counterparts, as well as infinite contrast ratios (due to each pixel being its own "local dimming zone") and the best viewing angles, they are predisposed to permanent image retention (i.e. burn in); when displaying particular imagery for a prolonged period of time, such as a channel's logo or the heads-up display (HUD) of a video game, said imagery will become stuck on the screen. So, aside from watching movies, OLEDs are not an ideal choice. A regular LED LCD with good local dimming is a more practical choice.

I game and watch TV on my OLED a lot and I've had no issues with retention.

How long have you had it and how many hours per week do you game on it?

[koberulz]

Over a year, and I've had several five-hour Rocket League sessions.

Permanent image retention occurs after frequently repeated prolonged periods of time during which static imagery is displayed. A few five-hour sessions isn't going to cause any issues. However, if you were a hardcore gamer who spent five hours playing games every day, then you would have definitely experienced permanent image retention by now.

[koberulz]

Okay, so you get image retention if you're trying really hard to get image retention, but not if you're using your TV like a normal person.

I would recommend the LG OLED series. I have the B7A and love it. It's future proof for HDR, it has HDR10 and Dolby Vision... In my opinion, HDR is more important than 4k/UHD... I say that because to get the true affect of 4k, you actually have to sit close to the TV.

For my 55" OLED, it's recommended to sit 4' to 6' and that's too close for me. HDR, on the other hand, has been amazing. Black levels are great and colors pop with HDR.

If you go a different route, watch out for marketing terms like HDR Pro. That isn't true HDR and is used as a marketing tool to confuse consumers. HDR Extreme for Samsung is true HDR. Good luck and keep us updated on what you buy!!!
