I do think that the Carlton Bale chart is crap (endless dialog already about this), but I hesitate on the NHK chart a little.

 

It's claiming that at 40 feet, 1080p is not enough for a 50" screen.  Did I read that right?

 

The overall theme is in concert with my understanding of optics, but did it go a smidgeon too far?

 

400 pixels per degree?  Hesitating on this one.

I just paced outside the house, away from the picture window opposite my 60" TV to what I think is 40' away.  Note, 60", not the 50" I mentioned above.  With my hand held in front of me, it's less than the width of 3 fingers.  That's ~600 pixels per finger width (2K).  Having trouble with this.

 

On PAPER at arms length, (if my finger pixel width is correct), that would be maybe what?  1000 dpi? (monochrome, not color composite printing because of half-tones screening)  Having trouble with this.

 

I don't think I could see the difference (again, monochromatically) between 1000dpi and 2000 dpi (if it were.  Or at least, I've forgotten if I could or not.

 

Did I do this correctly?

The NHK chart is based around recreating reality. Not what's good enough in a home environment for really nice image quality, but to fool the eye into thinking what you are seeing is real. So that you can never see the pixel-based nature of the display.

I think a more realistic target is 100 pixels-per-degree which gets you 90% of the way there, if you look at the data.
I seem to recall the Carlton Bale charts being based around 60 PPD, so as I have been saying along, you basically double the distances on his chart.

Ok, thanks.  But the current argument raging along is at what point you can tell a difference between 1080 and 2160 (and and and...).  Reality or not, they're still also stating that there is a visually identifiable difference between 1080 and 2160 on a 50" screen at 40 feet.  Or am I misunderstanding something here?

Maybe someone pulled a prank and inserted the visual acuity of an eagle in the place of a human while others were not looking. That is goofy.

What is the REAL story about Carlton Bale and his great viewing distance charts? What will be the name of the charts that will be produced to sell 4K sets?

He's just a home theater owner that made a theoretical cart many years ago that got all the brainiacs all excited without really knowing anything factual or tested the theories on actual displays, because they didn't exist yet...............

You could have found his web site if you'd put two and two together. rolleyes.gif

Stop all these comparisons and take it with a grain of salt, yes 4k looks better, yes its getting cheaper and mainstream, yes its the new product that new buyers will look at and buy not because its only new but because it looks better too (average customers got a taste too!) and they will not buy a TV everyday!, no content but upscaling in decent brands are doing a good job, its not a point of view its a cheer reality
