Q: Video signal is foggy or un-cleared on the screen.  Make sure the VGA cable is properly connected.  There are various CAT5 cables, such as CAT5/CAT5E/CAT6 and STP/UTP types; If your application need long distance with high VGA resolution, please select higher quality cables.  Make sure the VGA resolution is not too high for the length of cable that is used. It is highly recommended to use "optimal CAT5 cable length" to obtain the best video quality while still saving the redundant cable length. Therefore, if the problem remained, please shorten the CAT5 cable length or reduce VGA resolution.
