Tech’s New Most Meaningless Spec: PPI - Gizmodo

Status
Not open for further replies.
HTC's new Droid DNA smartphone has plenty of qualities that make it intriguing. It has a quad-core Snapdragon chipset. It crams a 5-inch display in a body nearly the size of a One X or Galaxy S III. Its Super LCD 3 technology trumps the Super LCD 2 that made the HTC 8x display so lovely. By all accounts it's a wonderful device.

But one thing HTC takes particular pride in is the 1920x1080 display, good for a pixel density of 440 pixels per inch, the highest ever in any handheld consumer device. This should make tech nerds lose their shit, right? Not quite. Welcome to your new favorite meaningless stat: ppi.

Yeah it only matters when its too low.

It's like money.

Look how easy that was.

PPI has been around for fucking ever too. Why is a measure of pixel density meaningless? Ever play games on an old Atari Lynx?
 
That picture is also meaningless without any reference/context. They could all look the same from a regular viewing distance.

Phones are used within a foot from our eyes, it's really easy to notice the difference in quality. Obviously that difference is highlighted there, but still.

PPI is meaningless since you can hold the device at whatever distance you want.

Resolution and screen size both matter.
1080p on a phone? Yes please.

I'm not saying there's no difference, I'm just saying that picture is worthless without any idea of how zoomed in that is. I can't hold any of those above phones close enough to my face that the pixels are as obvious as in the photo (not even remotely), and a future 5" phone with a 4K display could look just as much better in a microscope shot, but literally look identical to the DNA at any distance

PPI is important because I hold all my electronic devices exactly 1 inch from my face when i use them

yeah maybe for 4-5 inch smartphones it meaningless but monitors and tv's need some fuckin help , my CRT's were much better and that is 12 years ago come on.
 
i have seen this phone in person, or at least the near-identical japanese variant, and i can tell you that it sure is not meaningless — it's almost certainly the best mobile display ever shipped on a production device. you might not be able to perceive individual pixels, but taken in totality you can definitely see the difference next to a 300 ppi phone.

the valid question is whether or not the inevitable processing and battery life tradeoff is worth it vs other excellent screens like those on the iphone 5 or one X. my suspicion is that it probably isn't for now, but that doesn't mean we shouldn't keep on pushing display tech forward.

Hold this image far enough away and nudity appears!

Resolution divided by size in inches equals PPI. PPI isn't any more meaningless than any of the other three.

But all of them are meaningless without at least one of the other three, yes?

It's like a triforce!

Reminds me of a guy on here around the last iPad release, arguing it wasn't truly "Retina" because it was a few less PPI than the iPhone.

There is a point where this stuff gets absolutely ridiculous.

Honestly, Gizmodo is completely right on this. As someone who's used most of the new tent pole flagship devices, even the Note II with it's sub 300ppi display, there's very little difference between these things. Unless you have your face to the screen and are pixel peeping to a stupid degree, it's really quite pointless. For me, once you get to the 300ppi range, black, white, contrast and colour accuracy are far more important.

It's pointless because after a certain PPI there is no noticeable difference unless you hold your phone 2 inches from your eye constantly. Actually I would say its probably better to balance the tradeoff between powering the display and the ppi rather than just making the screen the highest ppi just because you can.

I know android OEMs have turned the phone market into the pc arms race equivalent though. So carry on.

I can make a phone with 24 cores too. But why? Just because. lol

Gizmodo apple shills duh... The same apple shills that no longer get invited to Apple events... Keep living the dream fools.

It's true, past a certain point this shit doesn't matter. Those pics were taken at like 10X zoom, it's a completely meaningless comparison even if you do think it looks better.

"Our screen is so amazing you can only see the detail under a microscope." Guaranteed someone will sell technophiles with a line like that because it sounds so much cooler than it actually is.

If you're gonna push all those pixels why not try something more meaningful like 120FPS or stereoscopic 3D?

Yup, now that Android has a phone and tablet with PPI greater than iPhone & iPad, Gizmondo calls it pointless.

It's always been pointless above a certain point, it's just Apple are very clever in marketing well enough that people forget how silly it all is.

I returned my Macbook Pro Retina recently (first creaked, second had major image retention) and honestly, going back to my 1080p 17" MBP and the screen from the retina isn't what I miss. I prefer the 17's screen because whilst not quite as pin sharp, it is larger, brighter and almost as sexy. What I miss is the size, weight and thinness of the MBPr, not that huge ppi screen (which actually causes as many issues as it does positives).

If you don't understand that PPI becomes meaningless above some cutoff then you don't understand PPI.
