Section 1 - General Information
Congratulations on purchasing a MaxTech 17-inch high resolution color monitor.
The monitor uses one of the finest CRTs available in the industry. The 0.28 mm
dot pitch non-glare tube provides a crisp and vivid color display. The monitor
complies with the MPR-II standard to reduce electro-magnetic emissions. Ad-
vancedelectronicsanddigitalcontrolsmakeittheperfectmonitorforapplications
ranging from home computing to business presentations.
The monitor is compatible with VGA, SVGA, and XGA display adapters. It
operates at resolutions ranging from 640 x 350 to 1280 x 1024 with unlimited
colors. The monitor is PnP (Plug and Play) compliant to simplify setup and
configuration in Windows 95 or other PnP operating systems.

Appendix B - Video Cable Pinout
Appendix C - Power Saving Modes (DPMS)
VESA Display Power Management Signaling (DPMS) defines a method for a
computertosignalthemonitortoreduceitspowerconsumptionwhenidle.DPMS
features must be supported by both the computer and the monitor. This monitor
supports DPMS “SUSPEND” “STANDBY” and “OFF” modes. Computer support
of DPMS requires the use of a DPMS compliant video card driver.
The monitor enters DPMS STAND-BY or SUSPEND mode when the computer
turns off either the Horizontal or Vertical Synchronization signal. These power-
saving modes reduce the monitor’s power consumption to 20W. When the
synchronization signals are re-enabled the monitor returns to normal operation.
The monitor enters DPMS OFF mode when the computer turns off both the
HorizontalandVerticalSynchronizationsignals.Thismodereducesthemonitor’s
power consumption to 1W. When the synchronization signals are re-enabled the
monitor returns to normal operation.
