Slef Diagnosis

The StudioWorks 20i has a convenient SELF DIAGNOSIS 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 DIAGNOSIS OSD menu with the "CHECK S/CABLE" and one of the "STATUS" items highlighted (such as BNC or D-SUB). This would be a clue for you to check the signal connections and to make sure you have the correct input (BNC or D-SUB VGA) selected.

The SELF DIAGNOSIS OSD may also appear if you exceed the monitor's operating limits, such as the maximum resolution of 1600x1280 or the frequency refresh rates of 30-85KHz Horizontal, 50-120Hz Vertical.

The other items on the SELF DIAGNOSIS OSD are actually just feature highlights, letting you know of certain major features of the StudioWorks 20i.

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.

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 orange 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 orange 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:

Normal operation : Maximum 130 Watts

Suspend mode : 15 Watts

DPMS Off : 6 Watts.

Video Memory Modes

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

For convenience, the monitor has a 32 mode memory of which 12 modes come from the factory preset to popular video modes as described below.

Resolution	H-Freq.	V-Freq.	HS. pol	VS. pol	Mode
720 x 400	31.467KHz	70.082Hz	-	+	1
640 x 480	31.463KHz	59.929Hz	-	-	2
1024 x 768	35.522KHz	43.479Hz	+	+	3
640 x 480	37.500KHz	75.000Hz	-	-	4
800 x 600	46.875KHz	75.000Hz	+	+	5
1024 x 768	60.023KHz	75.029Hz	+	+	6
1280 x 1024	63.981KHz	60.020Hz	+	+	7
1280 x 1024	79.976KHz	75.025Hz	+	+	8
640 x 480	43.269KHz	85.008Hz	-	-	9
800 x 600	53.674KHz	85.061Hz	+	+	10
1024 x 768	68.677KHz	84.997Hz	+	+	11
1152 x 870	68.681KHz	75.062Hz	-	-	12

Modes 13-32 are empty and can accept new video data.

If the monitor detects one of the above signals 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 13). When you now adjust the digital controls to your preference, these image settings will also be stored in mode 13. Whenever your video card or PC switches to the mode that the monitor recognizes as mode 13, your personal image settings will also be recalled.

A note about the video memory modes:

There are a total of 32 video memory modes, generally more modes than you will use at any one time. Of these 32 modes, 8 are permanent, factory fixed modes that cannot be changed. The remaining 24 modes left blank (empty). If you use up the 24 blank modes and still have more new video modes, the monitor will begin to delete modes 9-32 to make room for the new mode storage.

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, the monitor will save the new information in the next available empty mode (mode 13 if this is the first new data encountered).
2) If you have used up modes 9-32 with 24 new video modes, and the monitor has another mode it encounters, it will store the new data in mode 32 and delete mode 9, the lowest mode above the permanent factory fixes modes.
3) If even more new modes are encountered by the monitor, each new mode becomes the 32th mode and the old mode 9 is deleted. In summary, if the 32 modes are full and new modes are added, each old mode shifts to a lower memory mode, eventually being deleted if it is forced out of mode 9.

Example:All 32 modes are filled with following data 1 2 3 4 5 6 7 8 9 - - - - - - - - 30 31 32 m1 m2 m3 m4 m5 m6 m7 m8 m9 - - - - - - - - m30 m31 m32 factory fixed mode data

When new data is encountered (new data becomes mode 33)

By designing the monitor this way, you will always have the most common 24 video modes generated by your graphics card available, with your own image settings recalled automatically.

Troubleshooting
