"The iPhone 5 doesn't have a HD Screen" - What? Can someone explain this to me? - Page 10

One of the things I hate the most about this HD revolution is that before all this 1080p stuff I was able to buy 24 inch size monitors that support a 1900 x 1200 quite easily.

Now thanks to "HD" they push this standard down our throats and we lose out the resolution we should be getting.

The iPhone 4S is even worse, with a pixel count of 960 x 640 , you can't watch high definition videos on that. A retina display is not going to help that fact. And with 1136 x 640, you still don't have enough resolution to make it high definition. It would help if people stopped trying to confuse others with the whole retina nonsense. If it's not high definition, it's not high definition. End of discussion.

What would actually ultimately help is to stop trying to convince people that the fact that HD can't technically be applied to the iPhone's screen really has any impact on anything. It simply doesn't. Now, that actually does essentially complete the discussion (which really happened many posts ago when all of this has already been pointed out and discussed fairly well).

It might not have an effect on anything,

But the more people that know true information, and that is not being misled by false information, the better. I would just like for people to stop trying to convince everybody that the retina display on the iPhone is equivalent to a high definition display.

This thread has been an eye opener for me and many others.

Thank you,
Goodnight

Who is really bothered about the technicalities of having a HD screen on their phone? If I want a HD screen i'll watch my tv. The screen on the i5 is plenty good enough to watch media and for general use. Arguing about this is a waste of thought.

Retina is a Marketing term and HD is also Marketing term. The question is which term is more meaningful to the consumer. I’d argue that Retina is a fundamentally superior concept because it is a direct measurement of perceived optical clarity, while HD is indirect. HD only evaluates one aspect of image quality.
Labeling a product as RD is enough to tell me that the image will be of high fidelity without getting into a complex analysis of viewing distance, resolution, sub pixels and screen size.
I will concede that the RD definition is slightly too optimistic. 1Arc/Min is fine for the majority of users, but edge cases require a higher value. Images still require adequate anti-aliasing of text to remain sharp, and the arc measurement should be made at the furthest distance between pixel centers (diagonally). It is still far more meaningful then the nebulous “HD”.

In essence, Retina is BETTER than HD

I'm not really sure there was any false information to begin with. Apple hasn't really been calling the iPhone screen an HD screen, and no else has really been doing that (short of perhaps some random users on the internet, which really doesn't say much one way or another).

As for whether a display is equivalent to an HD display, whether or not that display is actually called an HD display, would in fact be a slightly different discussion than simply "is that display HD or not". A whole lot more would go into that than simply resolution, which is essentially the only thing that defines HD these days, and on at least some level that comparison would be subjective.

So, is an iPhone display an HD display? No, technically it's not. Is the quality of the iPhone display on par with what would be considered HD quality? Yes, for the most part it essentially is--at least there's practically no difference to a vast majority of users under most typical circumstances. This is what the whole discussion in this thread (and others like it) ultimately sums up to.

People in this generation seem so spoiled. Go back 20 years ago or live in a tent in remote areas on Earth and you wouldn't care how many pixels were on the screen. Just being able to call someone without being tethered to a wall or reading/learning about any subject in the world or playing games other than a circle eating dots or any of the hundreds of other things you can do with it, you'd accept it if it was only in black and white. We have more today than the richest kings of kings had centuries ago and we're complaining about the hue being slightly off or the picture isn't as crisp clear as others (WHICH, by the way, you would never know without comparing it with another display or reading about it). Why can't we be happy with what we have?

HD only stands for any screen that goes beyond a certain resolution, regardless of screen size. This is meaningless as it doesn't take screen size into account at all. If you had a 1080p screen measuring 100 inches diagonal, it would have terrible sharpness. Yes, it's 1080p (ahem... pardon me. "True HD" I mean.) but the huge screen size means it's stretching all those pixels onto a large surface area, at the cost of sharpness.

Screen resolution relative to size (PPI) is a lot more meaningful in terms of picture quality as it directly relates to how sharp the image will be. The more tightly packed the pixels, the better the sharpness and clarity.

For the iPhone, its current pixel density is more than enough.

You guys want an True HD screen then the iphone display is going to have to bigger. There is not reason for the 4 inch iphone 5 to go any higher you can not see the difference. If you want that HD then you are wishing for a Note II in iphone style. You will need a screen that big for it to matter.
