ViewSonic monitors comply with VESA DDC (Display Data Channel) Standards and are Plug & Play compatible. With the use of a DDC compatible video card, the EDID (Extended Display Identification) can be read from the ViewSonic Monitor by Plug & Play compatible software, such as Windows '95. In order for Windows '95 to detect the new monitor, you must ensure that the following minimum requirements are met: 1) A DDC compatible video card is installed. If your video card is not DDC compatible, then autodetection will not work. 2) DDC detection is enabled in Windows '95. This should be the case if you installed a DDC compatible video card. The *.INF file supplied with the video card should enable DDC in Windows '95. If this is not the case, then autodetection will fail. 3) A DDC compatible monitor with its *.INF file installed into Windows '95. Please Note: Manual installation of the ViewSonic's *.INF's file is always an option whether the above conditions are met or not. 2.1 AutoDetection Installation Procedure ======================================== NOTE: If Windows'95 is not installed on your computer, this option will not be available. 1) Insert the "Installation Diskette" into the floppy drive. 2) In Windows '95, choose: START `--RUN "A:\INSTALL" NOTE: Changed "A:" to "B:" if the diskette is in drive B: 3) Choose "Installing INF file" from the menu and execute. 4) After the "ViewSonic INF Installation is complete" message is displayed, shut down Windows '95 and reboot the system. The next time Windows '95 boots up, the monitor should be detected. You can confirm the setting by clicking: ( Mouse's Right Button) My Computer(Icon) `--PROPERTIES `--Device Manager `--Monitor The correct ViewSonic model should be displayed. If it's incorrect, highlight the current monitor, and click "Remove", then "Refresh". This will force Windows '95 to detect the new monitor. 2.2 Manual Installation procedure ================================== Use the mouse and click in the following order: (Mouse's Right Button) Background `--PROPERTIES `--Settings `--Change Display Type `--Change... `--Have Disk Choose "OK" for the default drive "A:" otherwise type in the correct drive letter, then choose "OK". The correct model for your monitor should be displayed if the requirements for DDC detection are met, otherwise, choose your monitor from a list of monitors. Choose "OK" and closed all windows. 3.0 TroubleShooting ==================== Problem: AutoDetection doesn't work. Solution: a) 1. Do you have a DDC compatible video card and is it operational? 2. Video cable damaged or monitor DDC code invalid. Go to the "Full-Screen DOS Prompt" & run the DDCtest program. Note: This program works only when a Plug & Play ViewSonic/OptiQuest monitor is in use! b) Is DDC enable in Windows '95? (Right Click) My Computer `--Properties `--Device Manager `--Monitor If "Unknown Monitor" is displayed, then the problem could be: 1) Damaged or wrong video cable? 2) Bad EDID data? 3) Non-DDC video card? 3) DDC detection is not enabled in Windows '95? If "Plug and Play Monitor (VESA DDC) " is displayed, then DDC is enabled, but the INF files was not correctly installed or the *.INF file might be damaged. Run installation procedure again or obtain the latest copy of the *.INF file. 4.0 Manual Procedure to Enabling DDC/Plug & Play in Windows '95 =================================================================== In the retail upgrade version of Windows 95, DDC support is disabled by default. To enable DDC, a value must be added to the Windows 95 system registry: "DDC=1", located in the software key (aka driver key) for the current display adapter. The Windows 95 installation disk for the display adapter driver should add this value if the driver benefits from DDC. To add the DDC value manually, follow these steps: 1) Click the Start menu on the Windows 95 toolbar, and select "Run..." from the menu. In the command line of the Run dialog, type "regedit", and press Enter. This will open the Registry Editor, which looks & works much like the Win3.1 File Manager. 2) In the left-hand panel of the Registry Editor, click on the "+" sign next to HKEY_LOCAL_MACHINE to expand its subkeys. Do the same for each of the following subkeys: -System `--CurrentControlSet `--Services `--Class `--Display `--+0000 You are now in the registry location that contains software keys for installed display drivers. Usually, there is only one display key present, 0000. However, there can be additional keys(0001,0002,etc.) depending on whether different adapters were previously installed in the system, or this is a portable computer with an adapter in the docking station, etc. If there are multiple keys,complete the remaining steps for each of them. 3) Expand the 0000 key. You should see: -Display `--0000 `--DEFAULT `--+MODES Click on DEFAULT. The right-hand panel of the Registry Editor should display something like the following: (Default) (value not set) drv xxxxxxxx.drv minivdd xxxxxxxx.vxd Mode 8,640,480 vdd *vdd, *vflatd These values represent default settings about the display driver, such as its driver file names, mode, etc. Other values may also be present. This is where the DDC key will be added. 4) Position the mouse cursor over the right-hand panel of the Registry Editor, and click the right mouse button. A menu will appear. Select "New>String Value". This will create a "New Value#1" value in the Name column. Type "DDC", and press Enter. Double-click the word "DDC", and enter "1" for Value Data in the Edit String dialog. If you need to correct a mistake, you can delete the new value you created and start over. 5) Close the Registry Editor. There is no need to save the changes, this will happen automatically. The next time Windows 95 restarts, it will attempt to detect a DDC compatible monitor. NOTE: The procedure above as obtain from Microsoft Windows '95 Article "Support for VESA Display Data Channel (DDC)" Version 1.0, March 1, 1995. 5.0 Additional Information =========================== For further assistance and technical support, call: Customer Service (909) 869-7976 or 1-800-888-8583 Mon-Fri. 7:00 AM-6:00 PM Pacific Time.
