I'm not 100% sure this is the right spot for this post, so Mods feel free to move it as necessary.
Here's my current configuration, idea and my assumed solution. I just wanted to throw it out to the pro's here on the forum to make sure I'm going down the right path before purchasing the equipment.
I just bought a PJ (Viewsonic PRO8200) for my Man Cave, which should be here in about a week. I currently have a 50" 720p Plasma in there that the projector will be replacing. I have a PS3 as my sole source (Blu Ray & Gaming) that is hooked via HDMI to my Sony Receiver that then has one HDMI cable out to my 50". Once the PJ arrives, I'd like to take and hang my 50" in an adjacent workout room. My wife is also wanting me to buy and install a 40" in our bedroom so she can watch/listen to the news in the morning while she's getting ready. I was initially planning on getting a smart TV so it would also have netflix capabilities built in vs. having another box to deal with since it will be hung on a swinging arm mount on the wall.
I got to thinking and my idea is, once the PJ arrives I'll move my 50" into the workout room, then go and buy a "dumb" 40" TV for the bedroom, then I could use my PS3 as the source for Netflix on all three displays (PJ, 50" & 40").
I'm assuming I could buy a HDMI splitter that is powered. Run the HDMI cable off my PS3 into the powered splitter; splitting it 3 ways. One would go into my Receiver which then will tie it into the PJ for home theater surround, then I would run the other two outputs from the splitter up inside the wall, across the attic and drop them down inside the wall (my bedroom and workout room share the wall) then I could just hang both TV's (50" & 40") hook up the HDMI and using my Bluetooth remote for the PS3, whenever I want to watch netflix or a movie on either TV just run it off the PS3 in the other room.
Now I understand that a splitter will be sending the same signal to all TV's simultaneously, so I won't be able to watch a movie in the Man Cave and something on Netflix at the same time for example. But, I really can't imagine a scenario when I'd be trying to use two of the displays at the same time (and the PS3) anyways.
So will this work? Any input on which splitter to buy? Also my rough measurement for HDMI cable length to go up inside the wall and across the attic would be about 35 feet. I've already started looking at cables and splitters on monoprice.
Thanks for any input!
