Not a FAQ but here goes:Originally Posted by rmason
1) 0 (zero) feet. As soon as the cable exits the case, you get interference. Now, how far before you really see a "bad" picture. That depends on lots of things and can't be predicted. I run 15ft of VGA cable in my car. The picture is definitely worse then just the 5ft cable attached to the monitor, but I'm happy. I've seen/heard of people running much much longer with well built cables (you can break out each conductor in a VGA cable to it's own high-quality RG6 cable, some think it's overkill, but others swear it'll let your run 100 feet.
2) That's tough. The home theater PC guys over at AVS Forums have tackled this and have lots of opinions. Someone there once recommended bettercables.com, keep in mind these get REALLY expensive quickly, their "Silver Serpent VGA Cable" is $140 for 15 feet. Hey, you said quality. In general, the "which cable is better" question degrades into "is monster cable worth the money". That is, lots of opinions, not a lot of facts.
3) Yes. I can think of two:
- DVI, just like the DVI connector on your desktop LCD screen. You need a DVI out on the video card and a DVI in on the screen.
- LVDS, read this. I think the max is 15 meters. But, this is harder then it looks.
4) Keep the data cable as far from power cables as possible (anything cable in your car that powers something is a power cable), I ran my VGA and USB down one side of the car where nothing else was, the power for the LCD down the other.
