One fun thing to note is that at 3840 x 2160, Thunderbolt would not be able to drive the display - being that it can only handle 10gbps of data per device (you'd require 12). You could use all of its channels, but you'd lose daisy chain capability and thus arguably the point of it.

Regular displayport however can, and still do it with 10 bit colour channels (30bpp).

Could you explain how you got to the 12gbps figure please?
 
I get if fully well, you do realize that you have to enable this functionality.

Funny that you should mention people not getting it.

Have a look at a couple of Macs with different screen sizes. You'll notice something very funny. The screen UI features are not the same size. They are the same number of pixels, but that does not translate to the same physical size.

If you don't believe me there is an iPad app that turns iPad 3 into a HiDPI screen for a Mac. Once set up correctly UI elements do get drawn properly.
 
Retina Displays are the normal evolution ... whats the problem. Retina is just a term for a very high resolution display.
It is better for your eyes!

Hopefully Apple jumps on that train with the upcoming refresh, can't wait any longer.
 
Is this the post low resolution LCD era ?

So it sounds like we will be entering a resolutionary period guys!

Oh god I'm going to puke over these apple buzz words
 
All this talk about super-high resolution screens is great, but what happens if/when web sites start using super-high res images??? Slower web loads, longer downloads, more bandwidth = we burn through our data plans for mobile, and we make a small dent in our home bandwidth limits as well.

And unless we drop the web and just use apps to connect with sites, where the developers can have more control over their UI, web sites are going to look really bad, especially sites where people upload content, etc. Older web sites that are not updated anymore will look awful, and you run into so many issues.

I don't know how this is going to work. If I have to triple the size of all the transparent PNG files I use on my sites, those are going get crazy really quick. You would eat up your 2GB data plan in a heart beat.

High-res stuff works best when it's the complete package, like an app. But the web is different. The web will instantly suck in high-res, and most sites will never look good again.

Fair points, but then again, it's non-unique. This was seen in the transition from 56k to broadband. On the other hand, the current infrastructure will be able to handle the increase a little more gracefully. By the time that websites actually transition towards high-resolution, the hardware and bandwidth are likely to be more pervasive anyway, similar to the aforementioned shift from 56k. Due to bandwidth concerns, enough sites already check for a mobile browser, or have specific apps for content; my guess is that we'll see a shorter period of growing pains in this regard than in the past. Compression techniques have also improved to the point that video, etc. can be more readily optimized for these displays-all while minimizing the increase in bandwidth usage.

At one inch away, yes I can. And it isn't unlikely, it's scientifically based. The formula is:

tan(a/2) = s/2d

I'm amazed your eyes can focus on something 1 inch away, I hold my iPhone 1 inch away and it's a total blur. I get a headache even trying. It's not till about 3-3.5 inches that I can actually focus on the screen.
 
I don't want 1920x1200 on a 15" screen, elements are small enough on 1680x1050!

Maybe it is just me, but I like things being the size they are at 1440x900 on a 15" screen. I was happy for 2880x1800 for the 15" being the rumoured resolution!

HiDPI mode seeks to solve this issue. Don't fret. Apple's already several steps ahead of you.
 
If you don't believe me there is an iPad app that turns iPad 3 into a HiDPI screen for a Mac. Once set up correctly UI elements do get drawn properly.

You are claiming that if I have a window on for example a 27" iMac (109ppi), and move half of the window to the Hi-DPI 3rd gen iPad (264ppi), the window will have the same physical size for both halves?

If I get the 15" MacBook pro with standard screen (1440x900) and compare it to the identical 15" MacBook pro with the high-resolution option (1680x1050), you are claiming that the screen UI elements will have the same physical size on both screens?

Sorry, I don't believe you.

I believe what itickings is saying is that if you place a 13-inch MacBook Pro side by side with a 13-inch Macbook Air, as the Air has the a higher resolution in the same display size and aspect ratio (thus a higher pixel density) items on screen are smaller on the Air - eg the height of the menu bar is 4.2 mm, not 4.9 mm - even though on both it is being drawn as 22 pixels high.
When this is applied to a retina 15-inch MacBook Pro some are concerned that a display of 2880 * 1800 will have more pixels than both the standard 1440 * 900 or the "high resolution" 1680 * 1050 variation but the usable screen real estate will be reduced as the display will remain 15 inches in size but UI elements are displayed physically larger in the retina model than the current "high resolution" model, so less of them can be displayed on-screen at once.

First of all who is Intel to talk about this? When Microsoft says so it will be way more concrete.
Second, it won't happen because it can't as of today.

It is fine when you control the whole OS and UI like on the iPad. Even then the only reason it works with web pages is special rendering and that magnifying the page is expected by users.
But everything else doesn't work like that. All the UI elements will be Horribly small at those resolutions.

Right now the best we have to handle this issue is bandaid solutions like font size magnification built into Windows and CSS that auto detects resolution and adjusts font size.
No other elements are handled so it simply will not work.

This feels like the same crowd that says everything in the cloud, streaming etc. is the way of the future. Oh and optical drives are dead. I don't understand why anyone would want a matte screen on a notebook. etc..

You would think the "Techies" on this site would know better. But you're just as stupid as the average consumer.
 
I've watched the video, Sandy bridge could of had retina too, Just seems like selling tips for geeks!1 the video of this announcement that is. The average user does not care about all of this. There are people buying iMacs and MBP etc as we speak.

Computers now are so powerful the average user is getting much more than they need. Long my it continue.

People really need to watch the video! they used a 2 year old computer to show gains on a new 3rd gen core. They know sandy bridge could do this so didn't compare with Sandy!! Sandy Bridge iMac still rock people
 
Oh god I hope not. Standard 13" resolution at 2800x1800? So that's "retina" for 1400x900... I much rather have a regular 1680x1050 at 13" than a 2800x1800 "retina"... Current MBA is plenty sharp, I would like more on screen real-estate please...
 
Being addicted to obtaining new inanimate objects frequently to give yourself a feeling of purpose or status is a dangerous thing.

Yes! Your motto reminds me of the New Yorker cartoon, years ago, showing the lady who said "having thrown out the Sunday Times, gives me a feeling of accomplishment!"

Yep, we want something to absorb us, like toys that absorb your attention and draw one away from give attention to reality and what is.
 
I don't think you understand.
There are many issues that would need to be dealt with before it would work and that's just not going to happen in the next few years.

Mac OS is now resolution independent. When HiDPI screens are implemented the graphical elements, the UI buttons lists and text remain the same size but end up much sharper. Look at iPad 3 if you don't understand.



----------

I don't really think you understand the technology.
 
Even though I think that a 27" iMac or Thunderbolt display can all ready be considered "Retina" when viewed at a normal distance, I'll gladly welcome a 5120x2880 resolution display. Of course, the only thing we'll need is content to come out in ultra-HD if that were to happen.
 
You will still get resolution independence from Mac OS. The Whole concept of resolution independence is that text, lines or what ever, ends up the same size no matter which screen you are driving. Apple isn't leaving resolution independence behind in any way.

Why even have references to HiDPI? Well it is pretty simple, Mac OS still will need to know what sort of screen it is drawing to. On IPad this is easy as the screen is built in and the resolution is known a that time of manufacture. Macs on the other hand have a choice of built in screens or external screens, and no good way of knowing how many DPI an external screen might have. So HiDPI is simply a way to identify a screen capability so that UI elements get drawn at the correct size.

You haven't gotten this right. Mac OS X in NOT resolution independent and never has been.

Macs know how many dpi their "internal" screens have. Apple has struggled though so far, and failed at providing real resolution independence, that is to scale up the os interface as a whole to adjust to a user defined x factor. It's not that they don't know what macs have what resolution screens. Sure it is a complex problem to have the ui scale up or down elegantly (what with bitmaps and vector graphics) and developers should abide by this.

But at least ms has implemented some ri in text and ui elements and the os can in most applications scale up and down with satisfactory results.

This is a big advantage over os x wherein the better each macs resolution has become the smaller text and ui elements have become. For most people over 30 for example reading a safari adress bar and bookmarks in a 27" imac or a 17" macbook pro mac at the distance they are meant to be used is a headache. People were expecting some user adjustable font sizes within applications but that too didn't happen with lion. There really is no reason why a user has to suffer through incredibly small cmd click font in some of the macs I mentioned above, and there really should have been a user customizable option there (which would have also been easy to implement).

Apple aims at some point to have such hidpi screens that they 'll just double everything across the board. That still won't be satisfactory of course if the user wishes to select a custom sized font for some ui elements, but at least it will mean that text won't be as shrunk as it is today in most macs.

I fail to see however why they will opt to keep text size identical in all the macs, surely the distance an iphone and ipad are used as well as their screen sizes demand (and output) different sized ui font. Why then should the menu bar font on an imac be the same size as those of an air when they have different size screens and are meant to be used at different viewing distances?

What are you, 80?
 
Does anyone know why Intel placed the laptops under the "Halo" category? Is that their new branding for anything more powerful than an ultrabook?
 
Apple leads and the rest follows

But these resolutions have always been there. IBM made a 3840 X 2400 display about 10 years ago. so is it Apple leading or Apple following someone else then getting (taking) all of the credit for the change???

Internet speeds are increasing. Cell phone providers didn't arbitrarily set the data limit to 2GB. They set it based on current Internet usage. Once there is more data on websites they will have to increase it to meet the demand if they want to remain competitive.
