TV screen size to notice 4k resolution? - Page 3 - Blu-ray Forum

Opips3 · 12-11-2015, 08:35 PM

Beating a dead horse... bringing up/asking something that has been discussed a thousand times before

Don't bother me. I stick physical media.

Just got a 55" 4K TV and I sit between 6 to 8 feet away from the TV. Watched some 4K videos on YouTube and the difference is noticeable for me. I watched the "Slo Mo Guys" 4K videos and I was able to see the hairs on their legs with extreme clarity. I could also notice more of the skin texture on their face.

Also watched a soccer game in 4K and you could make out the fans in the stadium as if you were actually there. Lastly, I watched a video on YouTube where 2 guys with a jetpack are flying over Dubai. That was the most amazing thing I've ever seen! You can make out the individual buildings on the ground.

This is not a placebo effect. I switched between 1080p and 4K for the videos (downloaded both versions and played them off a thumbdrive). I'm in the IT fields so I may have more attention to detail than others, so for me 4K has been a great improvement over 1080p. Your mileage may vary so I would say go to your local stores and look at the 4K TVs (make sure they are playing true 4K content) and judge for yourself.

I will take a 77" 4K OLED (at 9ft) tv to see a big difference.

Is it worth it?

Why not your favour it. Like big hamburger or small hotdog?

Samurai, why did you stop reading? The author did say "most viewing conditions" by the way. Others, too, should read the article. It's actually just a start to understanding the big picture.

The point that many people miss, and that the article discusses, is that there's a lot more to picture quality than just resolution. Buying a non-HDR 4KTV is just buying soon-to-be obsolete equipment.

Would you buy a car based on HP rating alone? If so, then don't read the article. If you understand and agree that many factors influence a product's performance you'll probably get something out of the article.

For example: "The parameters that make up HDR include higher peak luminance, lower minimum luminance, greater contrast range and improved precision, minimizing quantization errors that are beyond the capabilities of existing standards to deliver, the Society of Motion Picture and Television Engineers (SMPTE) report explains."

I bought a non-HDR 4K tv because, to me, 4K alone was enough. I can absolutely tell the different, and it become glaringly obvious when you switch between 4K content and 1080p content.

I, like the poster above, also watched a Slo-Mo guys video through the computer and switch it between 1080p and 4K and on the exact same frame the different was astounding.

This is with a 55" tv about 6 - 8 feet away.

HDR will be great, and in 3 or 4 years when the price of HDR capable 4K tvs comes down to where I bought my current tv for, the $1000 to $1500 range, I will probably move this one to the bedroom and buy a new one.

All technology is obsolete the minute you buy it. If I didn't need a tv right now, I wouldn't have bought one. But since I did need a tv I bought the best one I could afford, which was a 4K LG.

because the word "most" does not make it smarter but idiotic.

what I mean is this, does the TV resolution matter if the person watching is

1) blind?
2) asleep?
3) texting his friend on his phone?
4) playing a game on his tablet?
5 ) looking across two yards into his idiot neighbours home that has not figured out curtains to play the game "let's guess what he is watching"
6) watching a scene which is just white?
7) watching a scene which is just black?
......

there are many conditions under which it does not matter. But they are all meaningless and useless. Any intelligent person should only care about one circumstance or condition does the resolution make a difference when I am paying attention to a detailed scene.

OK so now I have my 4K TV and I did see some clips on 4K and yes the difference is there. I downloaded a couple of 4K clips from youtube and mostly didn't look 4k but those which look true 4K were stunning.

I only have a 50 inch screen but 4K difference is clearly visible. Its not only about resolution and noticing fine details. The 4k image looks more colorful and crisp than normal HD. Sorry but I want to give a slap to all those professional so called geeks who say that you need a big TV to take advantage of UHD.

My TV is not HDR and I also have very very poor eyesight on my right eye (Keratoconus) but yet I can see the difference!

sukraj · 12-17-2015, 11:43 AM

anything over 55 inches is good enough

JayEmm · 12-18-2015, 11:24 AM

I used to have an 88" projector screen I viewed from about 8' away, and that was when I had a 720p projector. I had no real issues with that - but a 1080P upgrade would have been nice.

I now have a 75" TV that I view about 10ft away and that's 1080P. The blu-ray of pacific rim is incredibly sharp, I do not feel like I would gain from 4K/UHD at this stage.

As others have pointed out, right now there is an enormous drought of material with some sort of decent 4K master. It's a lot less stuff than you think which is finished in 4K - even stuff shot in 4K is only now being posted in 4K in a regular basis.

My current motivation is that I have a TV on average for about five years. 95% of the movies I watch on disc are currently 1080P. I have a PS4 and XB1, I doubt they will do anything more than 1080P. I don't want to have 95% of everything I watch go through a scaler for the next few years. There are only a few blu-rays I have which even max out that format.

That's my opinion, anyway. And I have been fortunate enough to see a fair bit of "reference quality" 4K material.

To answer the original question plainly, I think 4K becomes NECESSARY if you are viewing at something like 1.5-2x screen height away.

meremortal · 12-18-2015, 04:06 PM

In my case, it would probably take a front projector to really notice the difference as I sit about 12-14 feet away. Even dvds often look great at this distance when upscaled. But I'd like to go front projection again eventually when there are a few viable 4k options in the under $1k range.

ray0414 · 12-18-2015, 05:27 PM

I sit about 13 feet from my 65" Samsung js9500 4k tv, and to me,, 4k is obvious even from 13 feet away. You have to remember that not all 4k is created equal and there is alot of bad quality 4k out there. But the good stuff is easily noticeable, especially when you throw in hdr with its required 10 bit color depth. Creates an entirely different picture than what you are used to. Hdr can be differentiated from 100 feet away if side by side. Sdr is dull looking in comparison.

Blu rays look very very good on my tv, but because they are 8 bit they don't compare. There should be more excitement about the launch of uhd players.

JayEmm · 12-18-2015, 07:43 PM

Is the UHD disc format 4:2:2 or 4:2:0?

JayEmm · 12-18-2015, 08:01 PM

I think it is important to remember there is a big difference between an increase in resolution being noticeable, and an increase being necessary.

I am looking forward to HDR more than 4k myself, I am happy to see it is part of the spec.
