I'm looking at mounting a projector and finding best way to run cables for video.

The maximum distance estimated for cables from systems to projector is 35 feet.

The projector is a NEC VT695, some specs are:
taken from http://www.projectorcentral.com/NEC-VT695.htm

Quote :
"Compatibility:
HDTV: 720p, 1080i, 576i
576p
EDTV/480p: Yes
SDTV/480i: Yes
Component Video: Yes
Video: Yes
Digital Input: DVI-I
Computers: Yes"




I have an adapter to connect component cables to vga as an option.

I'm looking into running hdmi to hdmi and converting at the projector or running hdmi to dvi from a xbox360/ps3/cable box.

I suspect that the two options ultimately come down to cost, but as I look on monoprice and see an option for high speed hdmi cables (which seem to only increase the rate of transfer from 1080i to 1080p).

Any suggestions as to what might would be the better option?

Be careful when attempting to run HDMI over long distances, I had a LOT of problems with my PS3 transmitting over 10 feet.

Attempted to use boosters, HDMI over CAT6, all sorts, nothing worked. Finally, I was able to get to a distance of 25 feet by using this cable:

HDMI to DVI is probably your best option, just sometimes it takes fudging on the projector to get the resolution to look right. Just make sure to buy a HIGH quality cable (which will cost you) otherwise you'll have to downgrade your resolution to compensate for lost packets.

i was looking at something along the lines of
http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10231&cs_id=1023102&p_id=2753&seq=1&format=2

apparently it can transfer up to 1080p, but I was more interested in knowing about the degradation over such a long distance, cost, and if someone had experience doing something similar and had a better idea.

I expect I could cut down the distance to travel considerably if I felt that I needed to in order to get the quality though.

I use one of these
http://www.avovercat5.com/products/digihdmihr.htm

Overkill for 35 feet, but definitely gets the job done waaaaay better than straight cables do. We switched over from running 150 feet worth of VGA in our sanctuary to these and saved cash while improving quality at the same time. No more signal dropouts at higher frame cycles.

If you can switch over to component instead of HDMI you can save a ton of cash - those are only like $80.

They're pricey, but we run 720p in the 250-300 foot range without problem. Their products are rock solid- 90% of them have no power adapters (passive) and have almost no signal loss.

^yes. I use several of the Intelix products and have always trusted them. Most of our stuff runs waaaay past the recommended range without problems. They're all the same size and stack up nicely on a rack tray. Plus they have a wide variety of connections.

However, for this case I'd get the cheap one

Honestly I would get a cheap 40 or 50 foot HDMI cable (22 gauge) from Monoprice and test it out. I've got a 50 foot run and it's rock solid, no need for a signal booster or anything. At worst you're out like $40.

So I went in and got the cable I need.

New question:

Any recommendations for how to mount it to high wall/ceiling (think where crown molding would be if i had it) so that it is out of sight and can be painted over.

I got something along the lines of:
http://www.lowes.com/pd_69682-170-C210_0__?productId=3136757&Ntt=wiremold&pl=1¤tURL=/pl__0__s%3FNtt%3Dwiremold

If it doesn't work search for 'wiremold' from lowes.com

I've heard bad things with the adhesive backing and would prefer something I can screw mount and paint over to match the wall if thats the only option.

i'd be willing to bet they're the exact same product but with different screenprinted logos on the box.
look at the casing, it's almost identical

^i dunno; I got burned by monoprice on some shielded cabling. Their stuff was crap. Even in your hand it was waaaay thinner, but I ran it in the blame ceiling anyway just to see my signal go down the tubes

That said; I ordered anyway

orly? i've never had problems with monoprice, and i order a lot of stuff from there, heh... the one time i had a busted cable (and it was only halfway busted, at that), i called them and they shipped me a new one for free and let me keep the busted one.

I guess it all depends what cable you're getting but I was incredibly impressed by their HDMI cable. That shit is thick and like I said, no issues at all with a 50 foot run.
