Although these options might create some confusion it won’t take you
long to get used to the new configurations for DPI scalings in Vista.
You can open the Control Panel and open the Appearance and
Personalization options (then select Personalize), or you can
right-click in the middle of your screen and select Personalize. These
settings allow you to configure most aspects of the Windows UI,
including your screen background (wallpaper), screensavers, window color
schemes, sounds, mouse pointers, themes, and display settings. In
addition, here is where you configure your Windows Aero settings if your
display adapter (video card) supports it. One of the more useful
settings you can change is the Font DPI settings. If you type Adjust
font size in the Search box, you will see the link for the DPI Scaling
utility shown in Figure 1.6. The default scale is 96 DPI, which might be
too small. The second option is 120 DPI, which many users find to be
too large. If you click the Custom DPI option, however, you can use the
slider to change the font size to something that suits your specific
needs.
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 have 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.
When
you go to change the percentage of DPI the drop down button only allows
you to select up to 200%. However, if you move the slider you can go as
high as 500% (not recommended, but fun to see).
