Projector set-up help

[SupaTech]

Dear all, 

 

My new house is being built and I currently have a big dilemma. I have two rooms to myself and I am planning to have a projector in one room and connect it to my PC in an adjacent room. Here is a diagram: 

The projector is attached to the ceiling. 

I am planning to run an HDMI/Displayport cable from the Projector through the wall to the PC on the ground. Does anyone have any tips for how this can be done? 

Also, I will need to control the projector with mouse and keyboard as I am planning to game using the projector. Does anyone have any tips for how I can do this? Ideally, I would want a USB hub to connect a keyboard and mouse on the wall, but I am not sure whether this is possible or not. Alternately, I can have a wireless keyboard and mouse, but I am afraid of whether the connection will still be strong enough to still be sufficiently "linked" to the PC through a solid wall. 

 

Thank you so much in advance.

What is the wall made off? Brick/concrete or wood and drywall?

The wall is hollow and made out of wood. The house is still under construction.

I'd drill a 60mm hole in the projector room side of the wall for something like this for your mouse and keyboard to plug wireless dongles or whatever else in

To get the USB cables for the grommet through the wall on the other side, as well as to have a passthrough for a displayport cable, use these

And I'd really reccomend using a displayport cable for the monitor. I don't know how long the cable will have to be, but HDMI likes to crap out beyond 5-6m while you can get 10-15m on DP.

However you run it, ensure you use some large flexible conduit so you can replace the cable if it fails, technology changes, or you need another cable.

I fished m HDMI the same way as you did, we finished the ceiling in the basement, and a couple years later it just "stopped working".

Thankfully my projector can pass 4K wirelessly line of sight, so the HDMI wasn't needed anymore.

If the house is still being built, you have several options.  Running cable now could be problematic depending on the disposition of the electrical inspector, so don't just throw in some wire without talking to your electrician first; they may have to rip it all out to pass rough-in.  So, you can:

1. Prep the wall yourself to be wired later.  This can be done by installing "mud rings" on the studs where you want the connections to be in the future; then run a pull string between the rings and tie it off well.  This will allow you to pull wire between the two rings once construction is complete.  Normal face plates can then be installed on the rings.  Or,

2. Work with the electrician to prep or wire the cabling for you.  There are several commercial products for wiring home theaters in new construction that have a number of different cables bundled together; they may already be familiar with a system that is perfect for you.  This is more expensive then doing it yourself, but it often works better and it becomes someone else's problem.

Have him setup a wall outlet that has hdmi,ethernet,displayport, etc on it. Have one on the wall close to the projector then run a something to hide the wires if needed or if he is running stuff in the ceiling you an do that instead. Have another jack on the other side of the wall near your machine. Have him run the wires between the two.

 

Now you have a permanent connection point on this wall. Now you can plug/unplug devices in as needed directly to the wall jacks. I know ethernet might not be needed, but some of the nicer projectors can use the ethernet connection to access or mirror your screen etc. Hell I would have him toss a USB port or 2 on them lol. Then you could use a wireless mouse/kb without issue in there if you chose.

 

I would do something like this. For the 3 open slots I would get the inserts for USB, Ethernet, Audio (maybe... dport can carry audio)
