PowerStrip provides advanced,
multi-monitor, programmable hardware
support to a wide range of graphics
cards - from the venerable Matrox
Millennium I to the latest ATI Radeon
HD series. It is the only program of
its type to support multiple graphics
cards from multiple chipset vendors,
simultaneously, under every Windows
operating system from Windows 95 to
the x64-bit edition of Vista. A simple
menu that pops up from the system tray
provides access to some 500 controls
over your display hardware, including
sophisticated color correction tools,
period level adjustments over screen
geometry, and driver independent clock
controls. A powerful application
profiler can detect when programs are
launched and respond by activating
specific display settings, gamma
adjustments, performance switches and
even clock speeds - returning
everything to normal when the program
closes. In-game gamma hotkeys let you
light up the darkest hallways during
game play, and hardware control over
refresh rates - with floating point
precision - ensure you're never stuck
at just 60Hz no matter what OS you're
using. A quick setup wizard gets you
up and running with minimal fuss,
extensive context-sensitive help is
available for all controls, and live
updates are supported to ensure you're
always running the latest release.
Finally, an assortment of system and
productivity tools - among them,
extensive diagnostics, PCIe and AGP
device configuration, EDID decoding,
desktop icon management, a system idle
thread, Windows resource monitoring,
an anti-burn-in orbiting option,
physical memory optimization, an
on-screen display, and the most
advanced monitor support in the
industry - round out the compact 1MB
package.
