The message "Unknown Mode Detected" appears on my display. Your computer's display settings for screen resolution and refresh rate are set to values that are inappropriate for your FX75 display. See "FX75 Video Modes" on page 35 for a table of supported modes. I don't hear any sound coming from the built-in speakers. N Make sure the audio cable is plugged into the speaker port on the back of the display and into the speaker port on your computer. N Make sure headphones are not plugged into your system. If they are, sound goes to the headphones instead of to the speakers. N If your keyboard has volume controls, use them to increase the volume. N Click the Volume icon on the taskbar. Drag the Volume slider up to increase the volume. Also, make sure the Mute box is not checked. N If the speakers still don't produce sound or if you can hear only a very faint sound, it's possible that your sound card doesn't support passive speakers. You need a sound card with amplified sound output. The image is very unstable. N Set your PC to a supported video mode, preferably 1024 x 768 at 75 Hz. See "Setting the Video Mode" on page 13. N Restore the original factory settings by choosing Restore Factory Presets on the OSD main window. N Run the Auto Setup routine. See "Using Auto Setup" on page 21.
