For our church we installed a couple of LG 65" panels. One reason for choosing LG was that they typically will come up in the last power state/input, thus we installed switched receptacles with the control back in the A/V booth.
Unfortunately these displays have integrated Roku functionality, and that OS doesn't seem to support this.
I don't like to rely on using remotes as there are multiple problems with that: distance, losing a remote, dead batteries, power status of each display out of sync with other, etc...
Thus I'm looking for a "hardwired" solution.
The displays don't have a data/serial connection, nor do they power on with signal detect.
- IR blaster of some sort wired to Mac in A/V booth. There seems to be a lack of tools for this, and the ones that do exist are pretty expensive for a glorified "On button"
- Network based IR blaster. Solutions seem expensive, and not much info on them I've found
- Build an Arduino based IR blaster that simply sends a constant stream of discrete power-on commands, and install it on the same switched outlets the displays are on. I've found one write up of such a device, but rolling my own seems a bit of a hassle.
I'm rather surprised there's not more software that can just drive a USB IR blaster.
Any other obvious solutions to this problem I'm overlooking?
