As with many Churches we have decided to ceiling mount ours.
The run from the projector to the booth is 100' +/-
What will be the best cable to use for video, and a cable for audio?
Also I have read about boosters, if we need them, will there need to be a power source to run them?
Thank-you

I'm not sure what you are doing with audio. Typically in this type of setup, you have multiple sources and you run the audio and video completely separately.

HDBT (HDBaseT) is the way to get HDMI video from the source to the projector.

Audio is typically run from the source to an amplifier, mixer, or preamp, then on to an amplifier then to speakers throughout the space.

A lot of this is budget dependent, but I would definitely use HDBT for the extension system. Many units can be powered from just one side so you don't need to power both ends.

First, LAN connections, if they can be used for video at all, can't deliver full frame rate, full resolution, and are often significantly laggy compared to the source video. In simple terms, it sucks, don't use it.

As to why your extender doesn't work with your PC, I really have no idea. If you are using a cheap extender, that could be an issue. If the laptop is mirroring the local display, then it may be lower resolution than the PC which may be sending full 1080p or higher resolution, which the extender may not support.

I would hook up a local monitor to the PC and use the secondary connection from the PC over the extender.

I'm assuming you are using a HDMI or DisplayPort connection to whatever extender you are using.

But, you didn't specify a make/model of the extender, so that matters.

Resolution REALLY should not be an issue as the projector is a very low resolution model (1024x768). But, I would get a 1024x768 monitor and hook that up to the PC, and also hook up the extender.

Depending on the length of the connection, a hard wired connection could be a viable alternative.
