272Preset Timing Modes― This product can be set to only one resolution for each screen size to obtain the optimum picture quality due to the nature of the panel. Using a resolution other thanthe specified resolution may degrade the picture quality. To avoid this, it is recommended that you select the optimum resolution specified for your product.Check the frequency when you exchange a CDT product (connected to a PC) for an LCD product. If the LCD product does not support 85Hz, change the verticalfrequency to 60Hz using the CDT product before you exchange it with the LCD product.The screen will automatically be adjusted if a signal that belongs to the following standard signal modes is transmitted from your PC. If the signal transmitted from the PCdoes not belong to the standard signal modes, the screen may be blank with the power LED on. In such a case, change the settings according to the following table byreferring to the graphics card user manual.Resolution Horizontal Frequency(kHz)Vertical Frequency(Hz)Pixel Clock(MHz)Sync Polarity(H/V)IBM, 720 x 400 31.469 70.087 28.322 -/+MAC, 640 x 480 35.000 66.667 30.240 -/-MAC, 832 x 624 49.726 74.551 57.284 -/-MAC, 1152 x 870 68.681 75.062 100.000 -/-VESA, 640 x 480 31.469 59.940 25.175 -/-VESA, 640 x 480 37.861 72.809 31.500 -/-VESA, 640 x 480 37.500 75.000 31.500 -/-VESA, 800 x 600 35.156 56.250 36.000 +/+VESA, 800 x 600 37.879 60.317 40.000 +/+VESA, 800 x 600 48.077 72.188 50.000 +/+VESA, 800 x 600 46.875 75.000 49.500 +/+VESA, 1024 x 768 48.363 60.004 65.000 -/-- Horizontal FrequencyThe time required to scan a single linefrom the left to the right side of thescreen is called a horizontal cycle. Thereciprocal number of a horizontal cycleis called horizontal frequency. Horizontalfrequency is measured in kHz.- Vertical FrequencyThe product displays a single imagemultiple times per second (like afluorescent light) to display what theviewer sees. The rate of a single imagebeing displayed repeatedly per second iscalled vertical frequency or refresh rate.Vertical frequency is measured in Hz.
