Can we really see 4K resolution?

Yes, given the usual constraints, the quality of the source material, screen size and distance. As a new owner of an 85” 4K TV I can say that differences are definitely noticeable, however it’s not as great as the difference between standard definition and HD. UHD Blu-ray is quite excellent!

What size TV are you looking for and how far away will you sit? We went from a 60” 1080p plasma to a 75” Sony and we sit 17’ away from the screen. I can notice a little difference, but it’s not huge. The biggest difference to me is HDR video. Especially watching something from an Ultra HD disc as opposed to streaming. When watching a disc based video the improvements in PQ are noticeable.

Like most I suspect, I went from a smaller HD (40") to a larger UHD (55"), same viewing distance, so resolution isn't really an apples for apples comparison. Yes it's better but it's not night and day. As the previous posters have mentioned it's the HDR that really stands out. As with most things in video (and audio) the content makes more difference than what we are watching (listening) to it on. A quality streamed 4K60 HDR 4.2.2 picture is a revelation but a crappy picture from the source is still a crappy picture. I do also agree that 4K BD's are a big step up, a 4K movie shot on decent cameras can be like looking at the real thing, it's often that stunning.
And that's on mid range Samsung Series 6, so it's not necessary to spend the $big to see the difference.
Cheers Gary

I'll agree that HDR/Dolby Vision has a more noticeable improvement than 4K has over 2K. At least with my 65" OLED from 9 ~ 10'.

Easily see the difference on my Samsung 65” 4k set from a distance of ten feet. But it all depends on the source and how well it was shot/ produced. I’ve seen some gorgeous stuff on YouTube as well as 4k bluray.

In many cases you won't be able to see an individual pixel (the arc angle subtended by individual pixels is below the angular resolution capability of your eyes), but you will be able to see interesting macroscopic effects. Check out this article on The Real Reason for 4K and 8K Image Resolution at SMPTE 2016. Casey

Well seating distance is roughly 10 and a half feet. I can potentially accommodate a screen no larger than 60.

Well the important question is do you notice a differencer between a good 4k tv and a last gen 1080 p tv. And the truth is yes. The new 4k tvs really do outshine their old counterparts. Whether 4k is by itself terribly obvious or not, the picture does look better on average. I've noticed in general better black levels, better contrast and better color. Is it better display tech, HDR, 4k? I don't know but man the new tvs look really good. At walmart I encoutnered a 50 inch 4k HDR10 (!!) TV for under 300 bucks. I mean seriously?!

Well seating distance is roughly 10 and a half feet. I can potentially accommodate a screen no larger than 60. Here is what I would ask. 1). Why are you upgrading? Did your old tv go out, or just looking for something newer? 2). What size was your old tv and what resolution is it? A 60” tv at 10’ is not going to look that much different in 1080p than in 4K, but it’s like anything else with electronics. If you are upgrading from a mid level 1080p to a very nice 4K then you will see some benefits besides just resolution. If you go for a cheaper 4K tv the upgrades will be less. The good news is now you can get a very high quality 65” (if you can fit it) 4K tv for fairly cheap. 60” becomes a kind of odd ball size. Many manufacturers make their higher end TVs in 55”,65”,75” sizes and the 60” and 70” end up being more “base” models.

Yes - You should have seen the Yankees/Red Sox games last week. It was like being at Fenway.
1080i is very, very good. 2160p is amazing. 2160p HDR or Dolby Vision will bring tears to your eyes.
PS - I'm 100% convinced that OLED provides the best picture quality. I've had mine for about 1.5 years now (it's an LG 65"), and I'm very happy with the purchase (as is my wife)

You'll probably gain the largest improvement just by going to an OLED TV. It's blacks and other tech are extremely good. Then you'll gain some more by going to 4k. You'll gain again by going to HDR/DV. All of which are cumulative.
Black Friday isn't too far away so OLED deals should be aplenty.

Pedro why do you say 60 is the biggest yo ucould accomodate? Is it because you can't imagine wanting more than 60? Or is it a cabinet issue? There is a large difference at that distance between 60 and 65. I have a 60 and at first it looked huge. But now I'm eyeing a 65 inch.

Professional calibration is a MUST for any main TV room or theater room. Essential. Make it part of your budget.
As for the 4k discussion, we've had it all before 50 times over and it always ends up in 2 camps. I'm done discussing it.

Can we really see 4K resolution? Ultimately, I believe the answer to your question is yes. However, I think one very important factor to consider before judging whether there is a significant difference between a good 4k display and a good 1080p display is the "source" material. Many fail to realize that just because that new shiny disc says "4K UHD" doesn't necessarily mean that it is. Very few of these discs are actually derived from a "true" 4K digital intermediate. Most are "up-sampled" to 4K from a 2K digital intermediate and given an HDR pass. Do these discs look better than their conventional Blu-ray counterpart…? IMO, yes... they most often do, but not as a result of the small boost in resolution alone. In most cases, they were sourced from the same DI. For the UHD disc, HDR is what makes the difference. The same is true for streamed content. If you truly want to see a "good" 4K display really shine, you'll have to get source material that is up to the task. True 4K/60p content shot with a high resolution lens with HDR on an OLED is simply mind blowing...

Don’t forget that 1080 tvs under 40” are hard to find (new) and the prices are not so great. So probably you will be “forced” to get a 4k tv anyway.

I have a $400 tv that looks like a 1K tv picture wise. I wouldn’t have thought of calibrating such an inexpensive tv but it was free from BB back in the day of free-bees. Now, I couldn’t imagine owning one that isn’t calibrated.
