CAT6 cable has a higher twist rate than CAT5/5e cabling. This means that it is less prone to noise as the higher twists help to cancel out noise in the signal pairs. But it also means that the pairs of cables are of different lengths and the three video colours, RGB, each sent down a pair of cables, will arrive at different times. This can cause a problem called colour split where the three colours Red, Green and Blue appear separately on the display. Normally the red is to the left and the blue to the right. This can be solved using this product\'s skew compensation function which will rebalance the length of pairs and bring the video colours back in line.
