Thread: VGA cable distance constraint

  1. #1

    VGA cable distance constraint

    I've always understood that the maximum length of a VGA cable is 6 feet. In order to have my Tricaster Pro more than 6 feet from the projector what are/is my options?

    Thanks

    I don't know the exact limit but for a distance of 150', they sell DVI extender over CAT5 cable.
    FYI:I have not used one.

    There are probably other options, but I have run monitors on 15 ft extensions.

    We routinely run VGA 25, 50, 100' with good cables. By breaking out the VGA signal into RGBHV 5 coax runs can easily do 150-200' if needed.

    Gefen also makes a DVI to fiber and back to DVI cable that can run even further.

    6' is definitely not a limitation.

    The limitation is the quality of cable. If you can't find them locally at a computer shop or Fry's then shoot me an email with the length you need.

    VGA over CAT5

    You should be able to run VGA up to 1,000’ over cat5 with an active VGA Balun and 150’ with passive Balun . We are runing VGA over CAT5 a 120’ at our church with no problem.

    And

    You can also run HDMI and DVI over CAT5 using Balun’s

    Hi,
    I have just started using a Aten KVM extender CE800 which works well good for 250m over cat5.

    When I install ceiling projectors, I use 33' and 40' VGA high quality cables with no problems.

    We routinely run our VGA's to screens without baluns 200'. BUT, we put a VGA distribution amp (splitter) behind the Tricaster to split the signal so that we can have a local VGA monitor at the tech table. The distribution amp bumps the signal. We got a 2x DA for like $50. We have run VGA around the perimeter of ballrooms without Cat5 baluns without a problem. We usually then loop-thru the projectors from one to another.

    We routinely do 200-300 feet over powered vga baluns. Eike makes a great one and even one that is vga in with a loop through and 4 cat5 out. Since we switched to this approach no more hum bars and picture quality is great. No more of that heavy rgbhv coax either. WE did a show in Vegas with 4 screens (15x20) for the Dooby Bros. and sent 720p down to the projectors. Stunning! Long live cat5!
