Cool, by the time I next buy a TV I'm hoping that will be fairly standard.

If one is diving so close to the limits that +/- 1% will make a difference then the error has already been made.

Yet the price might still be terrifying. The contrast ratio is excellent but could anyone really tell? Same for the speed? Sent from my iPad using Tapatalk.

It gets to the point where technology outstrips biology. We can’t see all those colours a screen is capable of showing anyway. Refresh speed at contrast ditto. And that’s people with good eyesight.

However, we can totally see all the colours some TVs are capable of and some refresh rates that some video uses. If you show a blue sky in 18 bit colour, you can clearly see the banding. That's 6 bits per RGB pixel, giving 262144 colours - which is commonly used on some TVs. Even with 24 bit colour, banding is often evident especially in areas of pure grey. 30 bits is obviously better, but I don't think any of the available digital broadcast services actually supply the information. The thing is, you need a screen that provides for more colours and a faster refresh than you can see - because otherwise you can see them!

Yes a factor above our ability to detect the differences, but after than that all it will do is be a waste of money for us humans. Though I suspect that there are some forms of wildlife who would still notice. We could be reaching the limits once they provide 40" TV with retina displays. Only a matter of time.

It's only a small percentage of the sited life on earth that sees in R-G-B. I don't think birds see a TV screen as anything other than a funny collection of flickery coloured dots.

Well dogs cats and chimps can watch TV quite easily. Though I was thinking of those with very fast reactions. Though some use ultra violet imaging as well as the normal light to make up their visual spectrum. They might not see TV's the same way as we do.

Birds for example see more than just 3 colours. They can tell the difference between say a monochromatic purple, and a blend of red-blue which would look the same to us. They would see the blended colour as exactly that - a blend of colours. Fish and insects also have completely different colour vision which varies drastically between the many millions of different species. Mammals are quite successful, but they are a tiny minority of the species on this earth. There are more insects in my garden than there are mammals on the entire planet. I have no data on various animals visual response times. I imagine that varies a lot too.

Well insects have very fast responses. Though would their vision just identify such a screen as a dots. As you said there are birds that are colour blind and some have wider colour perception possibly including ultraviolet. Cephalopods have very good vision as well.

If they can show eastenders in less than a minute then they're worth every penny! I hate it when my wife has that [LIFTED] on.
