480P Upscaled to 4K Questions

[blurayjunkie]

Has anyone tried a DVD on their 4KTV? Is there any difference between up-scaled 1080P VS up-scaled 4K, or is it too early to tell?

upscaled 1080 will look much nicer than upscaled 480. Esp on larger displays.

I agree, but am still curious to see how DVD's look

Like a lot things with newer TVs (especially OLED), the quality is highly dependent on the source material. A well mastered DVD can look good in 4k, assuming the up-scaling is high quality. Where you run into trouble is when the source bit-rate is bad or there's a lot of "dark" scenes. Same can be said for other material (like cable TV). Obviously, Blu-Ray is more forgiving (mostly due to higher resolution and bit rates), but I own plenty of DVDs that I'm not going to replace just because I upgraded my TV.

We spent Christmas day at my cousin's house who recently bought the Samsung curved 78" 4K, 3D LED TV. I believe it is the largest from the 7 Series. That was the first time I got to experience with 4K (aside from looking at TVs in stores) and I played many clips on my USB, from 480p to 2160p, viewing them from multiple distance points.

To answer your question, viewing a VOB file at 720 pixel-width was not as bad as I expected but it wasn't good either. When viewed from a distance (was standing about a meter behind the couch, so probably 4 meters from screen) it was fine; much better than watching a SD TV channel (which was terrible).

When I viewed the clip at 100% it was just a small square on the center of a huge screen and it surprised me how (relatively) good it remained when blown up to full size. However, when viewed from a closer distance, say 1-2 meters, then you get to realize how the TV softens everything. I can't explain it technically but it looked like it was like a pastel painting, the same effect you get when you highly reduce the noise of an image in Lightroom.

That's sounds about right, what you're probably seeing is some form of noise reduction. You can't upscale detail that is not there, so 480 content will look bad on a 4K display. Unlike 1080 material that give a lot more information for the the upscaler to work with.

How did a 4K source look, super sharp, like looking out of a window, or is that all exaggerated ?
