Just to clarify, were those situations using generic "VGA" cable or high quality bundled coax? I have many times run computer signals well over 30m without any problems when using five wire bundled coax. It is a physically large and more expensive cable but it also avoids potential issues such as skew that can occur if you use long runs of typical UTP cable (CAT6 is worse than CAT for this) and interfaces with no skew compensation.Hi, if I can offer my 2c worth. I have found that no matter what kind on money you throw at getting a good cable to improve the quality of your video, particulary VGA from a computer, you will always be disappointed. I have done a few installs of even 10-15m and found there is sufficient degradation in the quality to be noticable.
mrb not sure what VGA you have been using. all of the VGA cable I have used have 5 coax in them. for the 5 signals RGBHV. The grade and quality of cable varies based on the quality of the coax used in the manufacture. I have an installed facility that had hundreds of feet of RGBHV run through 4 floors of an office building in NYC which all ran flawlessly The longest run covered 4 verticle floors and transversed approximately 150' latterly granted there were line drivers installed on the lines but they all functioned flawlessly for years.
We just replaced them with fiberoptic transcievers.
