just bought myself an early Christmas present in an Optoma HD141X Projector :D which will be projected onto a 109" screen which I haven't bought yet.
however for those that have mounted them as ceiling projectors how did you run your cables ??
I face a couple of issues, my ceiling joists run perpendicular to the PJ :( making it nearly impossible to get a nice neat run to my amp which is mounted at the front under the screen area near floor level.
power I plan to take through the ceiling into the room above which is my spare room, ideally I want it to be hidden and clean as the ceiling is freshly papered and painted
any ideas?
 
Lift the floor of the room above. Drill the joists. Thread the cable.

Alternatively, runs a longer HDMI lead around the edges of the room (under the carpet if fitted) and then up the back corner and across the at high level to the back of where the projector will be. D-Line is a popular choice for trunking because of the rounded and quadrant profiles. Bear in mind though that you want a thick well shielded HDMI cable when there's distance involved. That means the bend radii will be quite large: 40+ mm, about the curve of a saucer. That's a bit of a challenge to accommodate in any trunking that wants to fit tight in to and around corners, so there's always a compromise. Bend a video cable too harshly and you risk crushing dielectric and introducing problems with the signal transmission. If the job involves fairly long runs then the cost of the trunking soon mounts up.

Normally at this point the question of using CAT cable is raised. The cable itself is relatively cheap and easier to run. The bulk of the cost though is in the Baluns that convert from and back to HDMI. For short distances (<20 m) HDMI cable is by far the most cost effective solution. Beware as well, cheap Baluns compress the signal before transmission. Those losses can never be recouped.

It's a bit of a hassle, but if you have the tools and time then in both the short and long run lifting the floor will give the neatest finish and keep the hardware costs to a minimum.
 
I had a similar problem with my set up. Didn't want any visible cables if I could avoid it.

In the end I bought a Neet HDMI>Cat6 convertor and went through the ceiling into the floor above with HDMI, converted to twin Cat6, ran the cable outside (tacked to the wall) and then came back in to where the AV processor lives, convert to HDMI and plugged in. Sorted. :)
 
I lifted the boards in the room above and put the cables through the joists, ended up running power, 2x hdmi (latest spec inc ethernet), and 2x CAT 6 leads.

Some of the cables go to an AV cupboard, another set drops down beind the projector screen and runs through some D-trunking.
 
Cheers for the suggestions, as it happens I do have 2 cat6 cables running inside the wall behind where the screen will be going. So looks like hdmi - cat6 could be the neatest solution
 
Sorry to go a bit off topic (don't think I could contribute much more in fairness) but did you buy this today on Amazon? Wondering what sort of price you paid if you don't mind sharing.
