Through this user guide, we will introduce you step-by-step all the features, functions and technical specifications of the LCD monitor. Surely you will have a refreshing experience working with the monitor. FEATURES The H274HL is a 15-inch TFT LCD monitor that is intelligent, microprocessor-based and ergonomically designed display, compatible with most analog RGB (Red, Green, Blue) display standards, including PS/V, PS/2, optional for Apple Macintosh Centris, Quadra, and Macintosh II family signals.

For horizontal scan frequencies between 31. 5 KHz and 60. 2 KHz, and vertical scan frequencies between 56. 3 Hz and 75. 0 Hz. In each frequency mode, the microprocessor-based circuitry allows the monitor to function at the precision-of a fixed frequency. · The resident memory allows for storing factory default settings and also additional user adjustment parameters. · The maximum resolution achievable is XGA (1024 x 768), best suited for Windows applications · The compact and sleek cabinet design saves lot of your desk space and makes your desk look neat and tidy. · The monitor is compliant with VESA-DPMS power management standard. The monitor is capable of storing up to 9 user modes. The only condition to store as a user mode is the new display information must have 1 KHz difference for horizontal frequency or 1 Hz for vertical frequency or the sync signal polarities are different from the default modes.

State ON OFF Power Consumption Normal <5W LED Light Green Amber The power saving states will be kept until a control signal has been detected or the keyboard or mouse is activated. The recovery time from Active OFF state back to ON state is around 10 seconds. DDC To make your installation easier, the monitor is able to Plug and Play with your system if your system also supports DDC protocol. The DDC (Display Data Channel) is a communication protocol through which the monitor automatically informs the host system about its capabilities, for example, supported resolutions and corresponding timing. The monitor supports and DDC2B standard. 8 User's Guide INSTALLATION To install the monitor to your host system, please follow the steps as given below: Steps 1.
