As seen on Ars review:

Lion has taken the hint from its younger brother. Arbitrary scalability is gone. In its place is a single check box to enable "HiDPI" display modes. (This option is still hidden away in the Quartz Debug application, so it's clearly not an end-user feature. But unlike all previous incarnations of resolution independence, this one actually works.)

Wow, zero responses?
 
I'm sorry this is off topic, but is the "automatically adjust brightness" option new? I don't see it in Snow Leopard (iMac 27, mid 2010)
How does it measure how much brightness to be set? iSight?

That option is only available on notebooks (possibly only MBPs?), as they have an ambient light sensor hidden beneath the speaker grill.
 
2010 11" MBA ultimate here, no option for HiDPI in my display settings. Is there a way to enable it for systems where it doesn't show up? I need to be able to do this because I manage IT for a doctor's office, the doctor is much older and we keep him on Windows 7 as it offers high DPI mode where SL didn't, but now that it does it'd be sweet to bring him over to Lion.
 
You can enable it in the Quartz Debug application (if you have the developer tools installed). Not sure you would want to, though, unless you're testing one of your apps. It's neither ready nor really meant to be used on current displays.
 
Ohh NVM!
I used the Quartz Debug that was in the "Developer-old", I activated it and its great (the supporting UI) but res too low (need a real retina for useable display ofc).
 
Requires XCode 4's Quartz Debug

You need to install XCode 4 and use its Quartz Debug. You can get this for free at the App Store (big download though). I preferred running:

Code: 
defaults write NSGlobalDomain AppleDisplayScaleFactor 1.5

opening tiny app "zoomed in", and then resetting it (for other apps) with:

Code: 
defaults write NSGlobalDomain AppleDisplayScaleFactor 1.0

but this no longer works. Anyone know how to achieve a similar effect (i.e., increase size of 1 app)?
 
It's a little strange that certain features of the desktop (the apple in the top left corner and the 1/2 inch markers in textedit are low res while the rest scales up nicely. Still a pre-alpha feature I guess...

The box that says "Restore scale factor to default (1.0) on quit" ?

No. You're apparently using an older version of Quartz Debug. The new one's UI resolution settings window should just show a single check box captioned "Enable HiDPI display modes".
 
I'm using HiDPI mode on a ViewSonic VP2290b (rebadged IBM T221) since a few months. It's pretty awesome, looking at a "normal" 100dpi monitor makes you realize how crappy those are :D

The VP2290b has 4 DVI ports, I'm only using 2 at the moment and get
30Hz refresh with the help of SwitchRes X which is enough not to be annoying (41Hz is max for my model).

Here's a screenshot of the monitor settings (the DVI ports are running 1920x2400 each):

I downloaded the new xcode 4.3, deleted my old developer folder, but for the life of me I can't find quartz debug in the xcode app bundle... And the old quarz debug prior to it being chucked away in the garbage did not have an hidpi option anyway... I need to download graphics tools I read somewhere but the link to apple asks for a dev. account which I 've not renewed for a year or so...

Great of apple to give xcode for free in the app store then take away the graphics tools....:mad:

So where's everyone locating the new quartz debug?

It's supposed to be there:
A: Q: How do I use QuartzDebug to debug graphics issues?

QuartzDebug is a debugging interface for the Quartz graphics system with several powerful tools to help you identify a number of graphics display and performance problems.

The Quartz Debug application is located in: /Developer/Applications/Performance Tools/

but I can't find it...

edit: nope, this refers to the old quartz debug...

You can get Graph Tools for Xcode (includes Quartz Debug) from Xcode > Open Developer Tool > More Developer Tools... menu or go to http://developer.apple.com/downloads directly.
 
I used one of the HiDPI modes briefly, as I thought it would solve the problem of not being able to see screen elements clearly from the couch (my Mac mini is being used as a HTPC). Unfortunately, they were really too big at that res to be useful. So now I just switch to 1366x768 when I need to.
 
iDisplay on iPad 3

I am not a developer. I just downloaded Xcode to try to enable the HiDPI mode on my iPad using iDisplay. Everything is super small so I thought, hey, time to use HiDPI mode. They guys at Airdisplay said they were toying around with this for their next release, so I was going to test this using iDisplay. I emailed the iDisplay guys and they asked if I had enabled HiDPI mode. So here I am trying to find QuartsDebug after downloading Xcode. I don't seem to have an /developer/applications/performance tools/ folder anywhere. What am I doing wrong. Is it because I am not a developer? Or am I just not looking in the right place?
 
See the posts above and get it from apple. :)

Activated hipdpi too, unusable mostly right now as word and other apps look like **** in terms of text, but it was a great relief to finally see larger fonts on the dock and finder, as well as clearer icons. Still I can't understand why the hell apple can't allow for some customizability of the font on the dock and a few more ui elements such as cmd click menus, and some larger sizes in the finder. when the hell are they going realise that they are killing people with accessibility issues, and that distort zoom in and out are simply not options...:mad:

May I ask what you are using the t221 with, is it a mini or a pro?

Also, if anyone is running ml dp 4 on an imac and they want to get back on us on how hidpi is working out for them it would be good to hear from them.
