User manual NEC MULTISYNC LCD1280

[. . . ] This symbol warns user that uninsulated voltage within the unit may have sufficient magnitude to cause electric shock. Therefore, it is dangerous to make any kind of contact with any part inside this unit. This symbol alerts the user that important literature concerning the operation and maintenance of this unit has been included. Therefore, it should be read carefully in order to avoid any problems.

[. . . ] However, because the LCD1280 is a high resolution, full color analog monitor, it may require the use of a graphics card (sometimes referred to as a video card, video adapter or graphics board) that supports high resolution graphics (1280 x 1024), 24-bit color (16. 7M colors), delivers an analog output, and which has 5 1. Determine the pixel frequency (DOT clock) output and the SYNC method used by the graphics card or system. For more information, refer to the graphics card or system manual or the FastFacts document referred to above. Make sure the H-SEL switch on the rear of the panel is positioned to the appropriate pixel frequency (if you are not sure, refer to the board manual or documents). 1 2 H-SEL Pixel Frequency (DOT clock): H-SEL Mode 1 -- 107. 5 MHz H-SEL Mode 2 --- 107. 352 MHz 4. Make sure the SYNC switch on the rear of the panel is positioned to the appropriate mode.

H-SEL Pixel Frequency Select Switch: selects the external pixel clock source for WS timing 1 (107. 5 MHz) or WS timing 2 (107. 352 MHz). Rough WS Horizontal Adjust (H-H1): rough adjustment for horizontal position of WS mode (16 dot increment per operation). Fine WS Horizontal Adjust (H-H2): fine adjustment for horizontal position of WS mode (1 dot increment per operation). Rough WS Vertical Adjust (H-V1): rough adjustment for vertical position of WS mode (16 line increment per operation). Fine WS Vertical Adjust (H-V2): fine adjustment for vertical position of WS mode (1 line increment per operation). VGA Clock Delay Adjust (V-C): adjustment of VGA pixel clock delay rate. Rough VGA Horizontal Adjust (V-H1): rough adjustment for horizontal position of VGA mode (32 pixel / 16 dot increment per operation). 7 LCD1280 10/29/99 9:25 AM Page 7 Controls Fine VGA Horizontal Adjust (V-H2): fine adjustment for horizontal position of VGA mode (2 pixel / 1 dot increment per operation). Rough VGA Vertical Adjust (V-V1): rough adjustment for vertical position of VGA mode (32 pixel / 16 line increment per operation). Fine VGA Vertical Adjust (V-V2): fine adjustment for vertical position of VGA mode (2 pixel / 1 line increment per operation). 8 Troubleshooting/Support Problem No Picture Check These Items · · · · · The signal cable should be completely connected to the video card/computer. Check BNC connectors to make certain that each connector has been attached correctly. Check H-SEL Switch and SYNC Switch to make certain that they are in the correct position according to the Installation section of this manual. Image is unstable or swimming is apparent · Signal cable should be completely attached to the computer. · Check the monitor and your video card with respect to compatability and recommended signal timings (Please see FastFacts document #52301280 and Appendix 2). · Check the SYNC Switch and H-SEL Switch for their correct position.
