Chapter 5 Troubleshooting
1. Is interference signal appeared on LCD normal when shutting down the computer?
In rare cases, interference may appear on the monitor. This may be caused by signal rate of VGA card and
is considered normal. The image quality can be improved by adjusting the phase or pixel rate automatically
or manually.
2. The membrane power light is not ON
Press the power ON / OFF on LCD membrane to check if the monitor is in the ON mode. Check the power
cord is properly connected to the LCD keyboard drawer and power outlet.
3. Screen image is not centered or sized properly
Press the button for two seconds to automatically adjust the image. Adjust the H-position and V-
position settings via On-screen menu.
4. Is the LCD keyboard drawer hot-pluggable?
The LCD keyboard drawer is hot-pluggable, but components of connected devices, such as the servers
and KVMs, may not be hot-pluggable. We suggest turning off the power to all devices before connecting
them. Apply power to connected devices again only after the LCD keyboard receives power.

To change monitor resolution, click Start -> Control Panel -> Display. Select Setting tab to adjust the
monitor resolution in Desktop Area. The available resolutions, "640 x 480", "800 x 600", "1024 x 768",
"1152 x 864", "1280
x 1024”, are determined by the display card in your computer.
