As anyone who uses an ultra-portable laptop would know, reading ultra-minimalistic weblogs with 9px-sized fonts on a high-resolution 1400×1050 display panel spanning an entire 12″ is like an everyday blessing for eye-care companies. Now’s a good time to invest in the laser eye surgery business.
Whilst desktop monitors has always maintained the adequately readable 96 DPI standard with LCD displays, pixel-density on laptops has reached as high as 144 DPI, and that means smaller interfaces and fonts. But who doesn’t want more pixels? The more pixels, the clearer the image.
Windows Vista aims to reduce the negative effects of high-DPI displays by introducing an updated DPI-scaling engine for the desktop compositor. This allows icons, interfaces and text to be scaled bigger to compensate for the extra pixels. In theory, everything should look just as crisp and detailed compared to the default 96 DPI. But in practice, due to lack of vectorized interface elements and icons, it’s not perfect. So exactly how good does it look? I’ve put together this comparison to show you exactly that.

As you can see, the interface scales quite nicely all the way up to 144DPI. Everything is still reasonably crisp and usable. But when you get to 192DPI, things become awkward. For example, the search icon in Windows Explorer is definitely out-of-place, and the power control buttons in the Start menu is way out of proportion. Also to note, sadly Sidebar gadgets do not scale at all.
But it doesn’t stop here.

The highest possible DPI setting was 500%. I wasn’t quite sure for which decade this feature was aimed at, but it was technically possible. Theoretically you would need a 12-inch display with a resolution of 7000×5250 to properly appreciate 480 DPI.
I knew I shouldn’t, but I wanted to attacked this giant enemy DPI for massive damage. (Sony E3 reference)
Avoid 480 DPI, for quite a while. 😉
Update: Thanks to Aaron Parker for submitting this. Here’s a great resource for more information on calculating DPIs. As well as an monitor DPI calculator tool to know exactly the DPI setting for your monitor size and resolution.
