Default Regular Blu-ray on 4K TV

Does a regular 1080p Blu-ray look worse on a 4K TV than on a 1080p TV? I thought maybe it would be similar to playing a non-anamorphic widescreen DVD on a 16:9 TV and zooming in but I have no idea if this correct.

From my experience, not at all. In fact on many occasions it can make it look even better!

I've just watched The Dark Knight & The Dark Knight Rises blu-rays this week, on my 4K player & 4K tv and they both looked amazing.

I'm a tad embarrassed to say I've been using a 720p plasma forever but I just upgraded to a 65" 4K and honestly I'm thrilled with how my Blu-rays look. I'm not sure if it's just the full 1080 I wasn't used to, some benefit of the 4k display, or a combo of the two. I recently watched The Pink Panther from the Shout! set and Criterion's Paris, Texas and they each looked gorgeous on this display. I had the same question when 4k started to take off but in my experience it's definitely not worse (again, with the lame 720 caveat).

I'll second that..... blu rays look much, much better on a 4k TV. I noticed deeper blacks and stronger colors immediately....

I remember watching DVDs on my old 4:3 TV and some of them looked better than on a 16:9 TV. Not exactly sure why. Maybe it's because old TVs handle interlaced content better. The colors weren't as vibrant and I'd see ghosting on the 16:9 TV.

Anyway, is there a technical reason why 1080p Blu-rays look better on a 4K TV than a 1080p TV? Are the pixels on the disc being duplicated or scaled larger?

Also, do any of you have 4K TVs that have a refresh rate of 120 Hz (or any other number that can be evenly divided by 24)? Since most movies are 24 frames per second, I'm curious if the 120 Hz TVs provide a more cinematic look and smoothen out the 2:3 pull down of 60 Hz TVs.

1080p blu-rays are upscaled to 2160p on an UHTV. The higher resolution is the cause of standard blu-rays to look better. On my LG -OLED, 1080p blu-ray looks absolutely gorgeous, you can tell the difference.

It's not higher resolution as the pixels are duplicated. If it looks better, it's due to better processing and the specs of the TV, like the better blacks of most OLEDs.

Think about it: Imagine an optical disc format with a resolution of 2 x 2 pixels and let's say each pixel is a different color (red, green, yellow and blue), remembering that each pixel can only contain one color value. Now you buy a TV with a resolution of 4 x 4 pixels. There will be 16 pixels, 4 of each color. Each set of 4 takes up the same space as the 1 at the lesser resolution. As such, there is no increase in resolution.

If there was increased resolution, there would be no reason to have a UHD disc format. As it is, on most movies, we're not getting any resolution benefit because the DI's are completed at 2K. When DI's are completed at 4K or higher, then maybe we'll see something. The benefit of UHD is primarily expanded color gamut and dynamic range.

So most movies on UHD had 2K DIs? Wouldn't that mean that in terms of resolution, UHD discs aren't any better than normal Blu-rays?

In those cases, yes, so read reviews that you trust.

The noise reduction of some sets of 1080p upscaling looks pretty awful imo.
MadVR does an excellent job upscaling 1080p to 4k however if you can take that route.

I really wish TV manufacturers didn't abandon high quality 1080p sets though.
Nothing ultimately beats content being displayed on a native res display. And it would've been nice to see OLED mature with 1080p and then have HDR with that instead of 4k. Which will suffer from lack of real native content for a long time to come.

At one time not so long ago I was one of those guys who said 4K was a fad and Blu ray looks just fine on my 1080p tv. Well after watching my Blu collection on my Samsung 4K tv for the past 3 months I can say my Blu's look 10 times better on my 4K tv then they ever did on my old Sony HDTV! So yes in my opinion 1080p Blu rays look better on a 4K tv. Just my thoughts anyway.

I was one of those same guys Steve! Now I'm in awe at the Samsung I finally picked up, and mighty impressed with the 4kHDR! The blu's never looked so good and the new UHD's look incredible...

No contest for me, the BD's I've watched upscaled on my panel look noticeably better. A factor is I went from a good 1080p projector to a 65", the projector could it match the sharpness on color of the panel. The panel is also much more accurate. My BD's never looked so good but they don't compare to a UHD copy.

Blu-rays look absolutely amazing on my 65 inch 4K set. I expected them to look bad, ala DVDs on an HDTV, but this was not the case at all. When I first saw how great they looked, I was absolutely stunned.

I invested in a 4K UHD player for a few UHD-only remasters, but my TV has mixed results with HDR. So my format of choice is still Blu-ray, and I am constantly blown away by the quality.

Is there something specific about 4K TVs that make Blu-rays look better than on 1080p TVs?

I see almost no reason to jump to 4K blurays as traditional blu's look great on my 4k tv, much better than in my 1080p set. The 4k upscale is really good and I see no big difference between 4k Deadpool and Blu-ray Deadpool, same with Pacific Rim (the only 2 4k films I own).

Are there any reasonably-priced 4K TVs that have a refresh rate of 120Hz (or any other multiple of 24)? I want to watch 24fps movies at the correct frame rate and not have my TV do 3:2 pulldown to match the 60Hz refresh rate.

My Kuro 5080, also 720p, is approaching 10 years of awesome service. The picture has been, and still is, amazing! Not embarrassed at all, and no one has ever noticed that it's not 1080p. But, like you, I'm about to take the plunge. I am just waiting for Robert Zohn and his crew to finish breaking in and calibrating a shiny new 65C7. All the comments so far have me even more excited to revisit my blus. Can't wait!

I can't speak for everyone but I watched The Fellowship of The Ring and the Nightmare Before Christmas on my new LG C7 OLED and the picture quality was phenomenal, it may have something more to do with the specific TV I had but it was like night and day when compared watching it on my old 1080p.
