VGAskewRX $199 Taiwan Quality
Bulk-Buy $159 (10+)

For use with VGA-Dist4+1 (above) and in situations where Skew is a severe problem, simply replace VGA-RX included in above with this device to reduce/eliminate severe Skew.

Also suitable for use in pairs (Daisy-Chained) to extend VGA transmission distance beyond 300 metres.

Ideal for situations where Cat5e, Cat6 & other Low-Crosstalk Cabling has already been been installed, low crosstalk TP is fine for a LAN but causes & exacerbates Skew when used for transmission of VGA signals. Crosstalk reduction in Cat-5e & Cat-6 is achieved in part by deliberately twisting the individual pairs in a 4 pair Cable at different rates to reduce coupling, the consequence of this is that pair lengths are unequal causing Skew.

Up to 1600 x 1200 @ 85 Hz | Video Bandwidth 122 MHz -3 dB | UTP I/O via 8p8c RJ45 | VGA Output 15 Pin RGB 1V p-p 75Ω, H & V Sync TTL | Horizontal 30-95 kHz Vertical 50-180 Hz | Skew adjustment 0~62 ns in 2ns steps | Power Supply included.

Results may vary depending on:

Resolution/Refresh rate, Cable-Length and Cable characteristics.

Output level of Source device (PC, DVR) and input sensitivity of Receiving device (Monitor).

&

In particular the length of RGB pairs, variations may cause Skew that will become more evident as Cable-Length, Resolution and Refresh rate are increased, Skew-Correct can be used to reduce/eliminate Skew.

Some brands/models of Monitors are very sensitive to sync levels and may function poorly.

Skew
If all three RGB Pairs are of equal length Skew will not occur, however in practice the number of Twists in each Pair does vary, this variation affects the timing of the signals arriving at the Receiver resulting in a horizontal displacement of the Red Green Blue images on the Monitor.

Skew increases with Cable Length, Resolution and Refresh rate, reducing these will reduce Skew, in most situations Skew-Correct or VGAskewRX will eliminate or significantly reduce Skew.
