As the resident A/V guru, I've been charged with finding a solution for my company's conference room.
We have two identical large flat-screen TVs with multiple sources. My plan is to have the following sources available on each: Cable TV, local PC, Video Conference, HDMI auxiliary in.
I need an easy way to control power and input source for these two displays. Ideally, I would have one set of buttons for each TV, namely Power On/Off, and Input 1, 2, 3, 4. I don't need volume control, as all audio is sent to a mixer, amp, and ceiling-mounted speakers. I also don't need channel buttons because the cable box is separate and has its own remote. (Although, I wouldn't turn down the opportunity to control that as well.)
The biggest problem is, since the two screens use the same IR codes, using a handheld remote (or anything blasting IR) is tricky. Luckily they don't have great receive sensitivity, so you can just aim carefully, but it's not very elegant. There are also a ton more buttons than we need on the remote, and I'd like to make this as self-evident and stupid simple to use as possible.
If it matters, the TVs are Sharp Aquos model LC-C6554U. I believe it has a RS-232 port on the back, but I'll have to check next time I have one off the wall mount. (Should be any day now - I have wiring work to do.)
