6 Setting the Display Resolution Choosing The Best Resolution All Liquid Crystal Displays (LCDs) have a fixed resolution that is the same as the maximum resolution that may be displayed on the LCD. In the case of the DV191 the LCD resolution is 1280 x 1024 pixels. This is also known as the “native” resolution of the monitor. Lower resolutions can be displayed at full screen through an interpolation circuit.
If you are using an Apple Macintosh, change the resolution by doing the following: MacOS 8.x/9.x 1. Click the Apple icon at the top, left corner of the screen, select Control Panel and then select Monitors. 2. Select a resolution of 1280 x 1024 pixels with between 60Hz and 75Hz refresh rate. 3. If refresh rates of 60Hz or 75Hz are not available, click Recommended in the Show drop-down box and change it to All. Select the resolution and refresh rate as above.
able to support these modes. For the native resolution of 1280 x 1024 pixels, for example, refresh rates of 60, 70 and 75 Hertz are supported. With Windows 95, 98, ME, 2000 or XP you can change the refresh rate of the graphics signal as follows: 1. Double click the Display icon in the control panel. 2. From the Display Properties dialogue box, select the Settings tab and click the Advanced Properties button. 3.

7 Adjusting the Monitor User Controls A brief description and the location of all LCD Monitor function controls and indicators: Figure 2-1 1 Stereo Speakers PC Audio Stereo output. 2 Speaker Volume Control Use to adjust the speaker volume (clockwise to increase, anti-clockwise to decrease). 3 Power Switch Turns the display on and off. 4 Power-On Indicator LED lights Green colour --- Power is ON. LED lights Yellow --- Monitor is in "Power Saving Mode". LED is off --- Power is OFF.
6 Adjustment Control Buttons Press the left button to decrease the OSD setting and press the right button to increase the OSD setting, when OSD menu is displaying. 7 External Headphone Jack The monitor speakers will be disabled when using an external headphone or external speakers. Adjusting the Monitor's Display OSD Function Menu To access the OSD Main menu, simply press one of the Function Select control buttons, and the menu diagram will pop up on the screen as shown on Fig.
OSD Transparency This function let's you set the transparency of the OSD menu (Not available when using DVI). Phase This lets you adjust the phase of the pixel clock to eliminate sampling noise (Not available when using DVI). Clock Adjusts the sampling frequency for the Analogue (VGA) to Digital signal conversion (Not available when using DVI). This function lets you select a colour temperature. Using the Colour Temperature Adjustment Control buttons to select the required colour temperature.
Picture Optimisation The easiest way to obtain an optimal picture is by using the Auto function in the OSD menu. This only works reliably if the graphics adaptor is set to use one of the monitor’s factory modes (see Table 1 in the previous chapter) and if you are displaying a suitable stationary image (such as the Windows desktop). The monitor will remember the settings obtained by the auto calibration settings and use them whenever you turn the monitor on.
6. With the Clock set to the optimal value adjust the Phase to further optimise the displayed image. You should now be able, with a combination of the Phase and Clock settings, to obtain a perfectly stable image. 7. Finalise the manual adjustment using the H. Position and V. Position functions If you are still not satisfied with the result, try repeating the above procedure using a graphics signal that has a different refresh rate.
8 Frequently Asked Questions The image is blurred, how can I get the best quality picture? ♦ ♦ Read chapter 6, Setting the Display Resolution, and select a graphics signal with the correct resolution and refresh rate. Then read chapter 7, Adjusting the Monitor, and make adjustments to the displayed image based on these instructions. Have you used a VGA extension cable? If so, remove the extension cable and check the displayed image.
No image is displayed, what can I do? ♦ Check that the light (LED) next to the monitor’s power button is lit and is green in colour. If the LED is green, press one of the Function Select buttons on the monitor to access the On Screen Display. If the message NON PRESET MODE appears there, please read chapter 6, Setting the Display Resolution and reset the graphics card to one of the monitor’s supported graphics signals. ♦ If the LED is orange the monitor is in power saving mode.
