Murph Posted August 29, 2018 Share Posted August 29, 2018 I just picked up my first 4k dvd. Is it really that big a difference in image? Link to comment Share on other sites More sharing options...
Calvinb1nav Posted August 29, 2018 Share Posted August 29, 2018 I haven't really noticed a big difference at least between a blu-ray being upconverted on a 4K player and a 4K DVD. As an aside, I don't notice any difference between 4K and a movie theater (of course they have a much better sound system...). Link to comment Share on other sites More sharing options...
Panzermann Posted August 29, 2018 Share Posted August 29, 2018 4K for home use seems mostly superflous. Each individual pixel is so tiny. Higher video refresh rate is more useful for a better picture and movement experience me thinks. Link to comment Share on other sites More sharing options...
Ssnake Posted August 30, 2018 Share Posted August 30, 2018 4K might pay off if your screen is super-large and/or you're really close to it.Eventually it'll supplant Full HD, but I see no benefit in adopting early. Link to comment Share on other sites More sharing options...

Oh yes. Lack of content to watch. most HD TV is not even FullHD for example. So better look for good colour presentation, good even lighting in a screen etc. and a well produced FullHD BluRay will be fine. Link to comment Share on other sites More sharing options...
Murph Posted August 31, 2018 Author Share Posted August 31, 2018 I can't really tell the difference, but I am old so that might be an issue. Lupe won a 4k TV at church in a raffle, and I purchased a 4k DVD after our last one went Tango-Uniform, but I really can't see the difference between blu-ray and 4k at this point. I purchased two 4k with a gift card at Best Buy, and meh seems to be my opinion so far. Link to comment Share on other sites More sharing options...
Ssnake Posted August 31, 2018 Share Posted August 31, 2018 Well, you can't beat physics. The human retina has a certain resolution limit, and as soon as the pixel size on the screen shrinks below that threshold - whether it is because of distance, or because the pixels themselves are becoming smaller, there is simply no way to tell the difference. So the question really is whether the individual pixel subtends an angle which your eye can still resolve. For a given size - say, a 50" monitor - there's a distance at which a 2K picture (Full HD) approximates the resolution of the fovea, typically at about 3...4m distance. With twice the resolution you can halve the distance , but who sits less than just two meters away from a 50" screen?(Kids on a Sunday morning maybe but they will watch just anything, even grainy black & white.)

Ssnake Posted September 5, 2018 Share Posted September 5, 2018 Okay, there's one possible advantage associated with 4K that hasn't been mentioned yet, and that's HDR. This gives a higher dynamic range in luminosity and to that extent, if done right, can be a substantial improvement. Link to comment Share on other sites More sharing options...
Ssnake Posted September 5, 2018 Share Posted September 5, 2018 Also, you may benefit from the occasional still picture if, for example, there's fine detail to be seen. Like in The Predator Schwarzenegger's tactical map in one scene (plus, the BluRay version of Predator was made horrific with too much digital smoothing everywhere). 4K allows you to recognize analog film grain.However, not every 4K movie actually IS 4K, a substantial fraction of the films offered are upscaled FullHD material. You still might get the benefit of HDR though. Link to comment Share on other sites More sharing options...
