(2) When the input display mode is not 1024 x 768, the image is smoothly expanded to 1024 x 768 dots with the scaling engine. After expansion from 640x350, 640x400, 640x480, 720x400 and 800x600 resolution, the text may look not so sharp, and the Graphics may look not so proportional. (3) net pattern happened in dot pattern or windows shut down mode (Based on Non-XGA mode) - Which symptom is normal performance for scaling chip. In case Beat Noise occurs, please press auto-adjustment key to minimize this symptom, and fine tune with phase key manually. Troubleshooting This LCD Monitor has pre-adjusted using factory standard VGA timings. Due to the output timing differences among various VGA cards in the market, users may initially experience an unstable or unclear display whenever a new display mode or new VGA card is selected. ATTENTION This LCD Monitor Supports Multiple VGA Modes. Refer to the Standard Timing Table for a listing of modes supported by this LCD Monitor. PROBLEM Picture is unclear and unstable If there's no display on the LCD Monitor, please perform the following steps : 1. Enter PC to "Shut Down Windows" status while you're in MS-Windows environment. 2. Check the screen to see if there's any black vertical stripes appear.
