What is skew??
Analog video presents a high quality image when the computer is directly connected to the monitor by short cables. However, in today’s data centers, labs, stores, as well as in digital signage installalations, video cables may be long, bulky, and expensive. To overcome these practical video cable length limits, KVM switches—in addition to both KVM extenders and VGA-only extenders—are used that send video through Cat 5e cables. "Skew" is the color phase and time errors that occur when R/G/B video signals are sent long distance over Cat 5e cables, and this can result in smeared, unsharp, color-fringed images that become visibly worse the longer the cables. ...more
The 2A-130G VGA EDID Emulator is designed for ATEN KVM extender or video extender installations that do not utilize a local monitor at the site where the computer/video source is located. The 2A-130G emulates and stores a default ATEN EDID (Extended Display Identification Information) setting in a non-volatile memory. This means the computer/video source can still "see" the display, even though it is not directly connected. ...more
