Longest DVI-D cable without loss?

[DyslexicHobo]

Since I've decided I don't want to spend over $200 to connect my non-digital output laptop to my TV for my HTPC setup, I've decided to instead try and run a DVI cable to my main PC in another room and use my laptop as a remote connection.

The only issue I can spot with this is the length of the audio and DVI cords. I'll be using DVI-D; is ~30 ft. too long? How much quality loss would I see or hear?

Thanks!

The official DVI specification mandates that all DVI equipment must maintain a signal at 5 meters (16 feet) in length. But many manufacturers are putting out much stronger cards and bigger monitors, so the maximum length possible is never exact.

There are 25 ft cables commonly available. 30 feet might be a stretch.

HDMI and DVI use the same exact signal (sans audio for dvi). HDMI can go 30 or 40ft w/o loss... There ya go.
I've never had a need to look up audio cables (but audio takes up a lot less bandwidth then video, i'm willing to bet). Also depends on what audio your going. S/PDIF or analog, or whatever others there are.

And what about an audio cable? Would that be just as reliable as an HDMI cable?

What kind of audio? I have regular copper wires going from cheap amplifier to regular speakers for over 20 feet and they work just fine.

Audio cables - the heavier the gauge, the longer they can be. i have had speaker cables running over 50 feet with no problem using 16 gauge.

Speaker cables and audio cables are two very different things. Speaker cables can be run for hundreds of meters. Unbalance analogue audio cables normally get problems with noise if longer than about 15 metres.
