Chapter 3: Installation
In these situations, set the MONITOR TYPE switch this way:
Monitor Type
Color VGA and XGA monitors
Monochrome VGA
8514/A
*Monitor type not listed here
*NOTE: If your monitors don't belong to any of these three types, you must set all
four MONITOR TYPE switch positions UP and connect a representative
monitor to MONITOR 1 with cable that carries the monitor's ID-bit leads.
If you don't have such a cable, contact Black Box Technical Support at
724-746-5500 or info@blackbox.com to order a cable that carries all
ID-bit leads.
8. Turn on the computer and the monitors. The monitors should now display the
computer's output.
This completes the VGA Video Splitter installation. Once installed, the splitter
shouldn't require any adjustments; you can keep it out of sight. It should now be
ready for continuous operation.

3.2 Extending Your Distance

The maximum distance to which a VGA Video Splitter can drive signals to a VGA
monitor depends primarily on the quality of the cable being used and the pixel
resolution and refresh rate of the VGA image coming from the computer.
Never use twisted-pair cable as video-extension cable, because this will cause
"ghosting" of the on-screen images. Table 3-2 is a guide for maximum distance at
various resolutions with high-quality VGA extension cable.
