Setting Up Multiple Monitor Support in Windows 98/Me/2000 253
Windows installation uses an unknown, Default Monitor, or Super
VGA display type, rather than a particular brand and model of
monitor, you will be prevented from selecting the higher, flickerfree
refresh rates. Install the correct driver for your monitor model
to get the highest refresh rates.
Comparing Video Cards with the Same Chipset
Many manufacturers create a line of video cards with the same
chipset to sell at different pricing points. Why not save some dollars
and get the cheapest model? Why not say “price is no object”
and get the most expensive one? When you’re faced with various
cards in the chipsetX family, look for differences such as those
shown in Table 10.21.
Table 10.21 Comparing Video Cards with the Features You Need
Feature Effect on You
RAMDAC speed Less-expensive cards in a family often use a slower RAMDAC. Buy
the card with the fastest RAMDAC, especially for use with 17-inch
or larger monitors. Faster RAMDACs are often paired with SGRAM
or DDR SRAM, which are the fastest types of RAM currently found
on video cards.
Amount of RAM Although AGP video cards can use AGP memory (a section of main
memory borrowed for texturing), performing as much work as
possible on the card’s own memory is still faster. PCI cards must
perform all functions within their own memory. Less-expensive
cards in a chipset family often have lower amounts of memory
onboard, and most current model cards aren’t expandable. Buy a
card with enough memory (8MB–16MB or more) for your games
or applications—today and tomorrow.
Memory type High-end video cards frequently use the new SGRAM
(Synchronous Graphics RAM) or DDR SRAM (Double-Data-Rate
Synchronous DRAM), with regular SDRAM as a popular choice for
mid-range video cards. Choose DDR SRAM, SGRAM, and then
SDRAM, in order of preference when possible.
Memory and core Many suppliers adjust the recommended speed of graphics controllers
in an effort to provide users with maximum performance.
If you have questions about the rated speed of a controller, check
the chip supplier’s Web site. Many reputable companies do use
overclocked parts, but the best vendors supply large heat sinks or
even powered fans to avoid overheating.
TV tuner You can save some money by having it built in, but it’s not as
important as the other issues listed earlier.
Setting Up Multiple Monitor
Support in Windows 98/Me/2000
Windows 98 was the first version of Windows to include a video
display feature that Macintosh systems have had for years: the
capability to use multiple monitors on one system. Windows 98
