get the optimum picture. Look at the centre section of the test pattern that has alternating black and white vertical lines that are each 1 pixel wide. There should be no vertical noise bands visible within the image. The centre section will clearly show the alternating black and white lines or a uniform level of noise will appear across the image once the clock adjustment is correct. Close the clock submenu by pressing Exit.
6.Select Horizontal Position and press Enter.
7.Adjust the horizontal position so that the image is centred. Its width should be the same as the visible width of the screen. Press Exit.
8.If some noise or distortion is still visible in the centre section of the test pattern, select Phase and press Enter.
9.Adjust the Phase of the monitor’s sampling clock to optimise the displayed image. The alternating black and white lines should be clearly visible. Press Exit.
10.Press Exit twice to close the OSD menu and save your changes.
If you are still not satisfied with the result, try repeating the procedure using a graphics signal that has a different refresh rate.
Notes:
You must use one of the factory modes. If the Auto button is not working, or the NON PRESET MODE message is shown on the OSD you are not using one of the supported modes. If you are having difficulties generating a supported mode, ask your computer dealer or the distributor or manufacturer of your graphics card for assistance.
The procedures described in this chapter should be performed for every resolution and type of graphics signal that you wish to use. For example, if a particular application requires a resolution of 800 x 600 pixels, but all other applications use the monitor’s native resolution, you will need to display the test pattern and make adjustments twice.
The monitor will remember your settings and use them whenever you turn the monitor on. Note that you may need to
