Maximum length of VGA cable?

post #1 of 4
Thread Starter 
Here's my situation: I have a HTPC hooked up to the plasma TV upstairs, and it works very well for this. However, my mom is looking for something that she can use as a workstation as well, and I'm not so keen on having MS Word bars burned in to my plasma TV. The Gigabyte 780g motherboard that I am using for my HTPC can output to HDMI and VGA simultaneously, so my idea was to buy a smaller LCD monitor, put it at her desk, and run a VGA cable from the HTPC to the monitor. The problem is that my mother's desk is about 20 feet away from the HTPC.

My question, then, is thus: what is the maximum length of a VGA cable before signal dropoff occurs (I would have thought 100 feet due to the analog nature of the signal, but I have heard reports of ghosting and picture problems after even 6 feet) and, if it is feasable, where I could purchase a 20-25 foot VGA cable in Canada?

I think you can go for longer distances but you need a booster sort of thing... I wouldn't go over say 50 feet though...
