Which hardware?

using WindoWs or oTher sofTWare calibration
tools will certainly solve any glaring image-quality issues,
and will ensure you don’t miss anything while gaming.
However, to be absolutely sure your monitor’s color output
is spot-on, you’ll need to invest in some hardware.
Two brands have the color calibration market pretty
much sewn up: X-Rite Pantone and Datacolor. The former
produces one of the most inexpensive colorimeters available, called the ColorMunki Smile. Don’t be put off by the
silly name, as this effortlessly easy-to-use gadget will give
almost as much calibration accuracy as devices costing
several times its $100 price tag.
Since the Smile is an entry-level device, you’ll need to
wait a relatively sluggish five minutes for it to complete the
color calibration process, but when it finishes and saves
the  freshly  tweaked  color  settings  to  Windows,  they’ll
load  automatically every time your system boots up. The
calibration sof t ware can also be installed on more than one
machine, should you want to calibrate your other desktop
computers or laptops.
The  only  downsides  with  the  ColorMunki  Smile  are
that it is unable to calibrate a multi-monitor setup, and it
can’t measure ambient light to ensure that your monitor’s
brightness is set appropriately. For that kind of control
you’ll need to step up to a device such as Datacolor’s Spyder
4 Pro. At $170, this is a more serious tool, but it will help you
get the very best from your monitor.
Of course, you can spend even more, but then you’re into
the realm of calibration kits designed to scan not only your
monitor, but also color match it with print material. Unless
you’re a die-hard photo-editing and -printing enthusiast,
this kind of money would be far better spent on a quality
monitor that’s likely to come calibrated fairly accurately
right out of the box.
