It can also be used with a Sun SPARC workstation as well as other sources using the 5 BNC connectors. The monitor provides crisp text and vivid color graphics with VGA, SVGA, XGA, and VESA Ergo modes (non-interlaced), and most Macintosh compatible color video cards when used with the appropriate adapter.

The monitor's wide compatibility makes it possible to upgrade video cards or software without purchasing a new monitor.

Digitally controlled auto-scanning is done with the microprocessor for horizontal scan frequencies between 30 and 85KHz, and vertical scan frequencies between 50 and 120Hz. The microprocessor-based intelligence allows the monitor to operate in each frequency mode with the precision of a fixed frequency monitor.

The microprocessor based digital controls allow you to conveniently adjust a variety of image controls by using the OSD (On Screen Display).

The monitor is shipped with 8 factory pre-programmed video modes that are permanently resident, and another 8 are set at the factory, but may be overwritten to make more room. In addition, there are 24 user storable modes, for a total of 40 memory modes.

This monitor is capable of producing a maximum horizontal resolution of 1600 dots and a maximum vertical resolution of 1280 lines. It is well suited for CAD work and sophisticated windowing environments.

For greater user health and safety, this monitor complies with the stringent Swedish Nutek MPR II requirements for low radiation emissions.

For low cost of monitor operation, this monitor is certified as meeting the EPA Energy Star requirements, and utilizes the VESA Display Power Management Signalling (DPMS) protocol for power saving during non-use periods.

Self Diagnostics

The Studioworks 28i has a SELF DIAGNOSTICS OSD feature that pops up when there may be possible causes of non-operation. The OSD would highlight a possible reason the display is not showing an image. An example of this may be when you turn on the monitor with no signal cable attached. The monitor will display the SELF DIAGNOSTICS OSD with the CHECK INPUT SIGNAL. This would be a clue for you to check the signal connections.

SELF DIAGNOSTICS CHECK : INPUT SIGNAL NO SIGNAL DETECTED

DDC (Display Data Channel)

DDC is a communication channel over which the monitor automatically informs the host system (PC) about its capabilities. This monitor has three DDC function; DDC1, DDC2B, and DDC2AB. DDC1 and DDC2B carry out uni-directional communication between the PC and the monitor. Under these situations, the PC sends display data to the monitor but not commands to control the monitor settings. DDC2AB has the function of bi-directional communication. For example, the PC can fetch screen data from monitor and adjust the screen with the PC keyboard.

NOTE : PC must support DDC functions to do this.

Low Radiation Compliance (MPR II)

This monitor meets one of the strictest guidelines available today for low radiation emissions, offering the user extra shielding and an antistatic screen coating. These guidelines, set forth by a government agency in Sweden, limit the amount of emission allowed in the Extremely Low Frequency (ELF) and Very Low Frequency (VLF) electromagnetic range.

Video Memory Modes

This multi-synchronous auto-scanning monitor can automatically detect and display several video modes.

For convenience, the monitor has a 40 mode memory, of which 8 modes come from the factory preset to popular video modes as described below.

Resolution	Hori. Freq.	Verti. Freq.	Hor. Sync pol	Verti. Sync pol	Mode
640 x 400	31.47KHz	70.08Hz	-	+	1
640 x 480	31.47KHz	59.94Hz	-	-	2
640 x 480	37.50KHz	75.00Hz	-	-	3
800 x 600	46.88KHz	75.00Hz	+	+	4
1024 x 768	60.02KHz	75.03Hz	+	+	5
1280 x 1024	63.98KHz	60.02Hz	+	+	6
1152 x 870	68.68KHz	75.06Hz	-	-	7
1280 x 1024	79.98KHz	75.03Hz	+	+	8

Modes 17-40 are empty and can accept new video data.

If the monitor detects one of the signals above from your computer's video card, it will recall that mode and any stored image adjustments you may have made before. If the monitor detects a new video mode that had not been present before or not one of the above listed factory presets, it will store a new mode automatically in one of the blank (empty) memory modes (in this example, mode 17). When you now adjust the digital controls to your preference, these image settings will also be stored in mode 17. Whenever your video card or PC switches to the mode that the monitor recognizes as mode 17, your personal image settings will also be recalled.

A note about the video memory modes:

There is a total of 40 video memory modes, generally more modes than you will use at any one time. Of these 40 modes, 8 are permanent, factory fixed modes that cannot be changed, and another 8 are set at the factory, but may be overwritten to make more room. The remaining 24 modes are left blank (empty). If you use up the 24 blank modes and still have more new video modes, the monitor will store information in the other 8 soft preset modes for the new mode storage. If additional new modes are encountered, the monitor will delete the lowest memory mode and add the new mode.

If you use a video card that has a number of resolutions and frequencies that do not correspond to any of the monitor video modes set at the factory, here's what will happen:

1) As the monitor encounters new video data, if you adjust the image control icons, the monitor will save the new information in the next available empty mode (mode 17 if this is the first new data encountered).
2) If you have used up modes 17-40 with 24 new video modes, and the monitor encounters another mode (41th mode), it will store the new data in mode 17 and the old data of mode 17 is deleted.

In addition, If the monitor encounters 42th new video data, the old data of mode 18 is deleted and 42th data will replace the mode 18, with above method, when this monitor encounters new mode, it can update from mode 17 to mode 40 sequentially and continuously.

Example:All 40 modes are filled with following data 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 ---- 38 39 40 m1 m2 m3 m4 m5 m6 m7 m8 m9 m10 m11 m12 m13 m14 m15 m16 m17 ---- m38 m39 m40 Factory fixed Soft presets mode data

When new data is encountered

Because the monitor is designed this way, you will always have the most recent 32 video modes generated by your graphics card available with your own image settings recalled automatically.

Energy Saving Design

This monitor complies with the EPA's Energy Star program, which is a program designed to have manufacturers of computer equipment build circuitry into their products to reduce power consumption during time of non-use.

This monitor also goes into its energy saving mode if you exceed the monitor's operating limits, such as the maximum resolution of 1600x 1280 or the frequency refresh rates of 30-85KHz horizontal or 50-120Hz vertical. When this monitor is used with a Green or EPA Energy Star PC, or a PC with a screen blanking software following the VESA Display Power Management Signalling (DPMS) protocol, this monitor can conserve significant energy by reducing power consumption during periods of non-use. When the PC goes into the energy saving mode, the monitor will go into a suspended operation state, indicated by the Power LED light changing from a green color to an amber color. After an extended period in the suspended mode, the monitor will then enter a semi-OFF mode to conserve more energy. In the semi-OFF mode or DPMS OFF mode as we call it in our specifications, the Power LED will still show an amber color. When you awaken your PC by hitting a key or moving the mouse, the monitor will also awaken to its normal operating mode, indicated by the green Power LED light. By following these conventions, the power consumption can be reduced to the following levels:

Power Consumption

MODE	H. Sync	V. Sync	Power Consumption	LED Color
Normal (Max.)	On	On	≤ 140W	Green
Stand-by	Off	On	≤ 15W	Amber
Suspend	On	Off	≤ 15W	Amber
Off	Off	Off	≤ 7W	Amber

Troubleshooting

Symptom: Self diagnostics message on back raster appear.

Possible causes:

■ The signal cable is not connected.

Symptom: The power led is illuminated amber.

Possible causes:

■ Display power management mode. (Move mouse to awaken PC.)
■ Check the computer power and graphics adapters configuration.

THE ABOVE WARRANTY DOES NOT APPLY:

• To damages or problems which result from delivery or improper installation.
- To damages or problems which result from misuse, abuse, accident, alteration, or incorrect electrical current or voltage.
- To service calls, which do not involve defective workmanship or material, such as head cleaning and expaining the operation of the unit.

Therefore these costs are paid by the consumer.
