Not really a problem, but you should be aware of that. BTW, from your drawing, are you trying to make the panel viewable from either room. If so, you should be aware that most, if not all double arm mounts cannot go all the way to +90 degrees, most go to 75 or so, including the Sanus. There is a way to remedy that though if you are handy.
My primary viewing angle will be from the bottom of the picture - this is a room where my treadmill is and that's where the treadmill is, and it's far enough away that (esp. when running) I was having trouble watching things and making out any text etc. on my 37" panel (which I just had on a stand). I'd like the option to occasionally angle it towards the right (looking down from the top) but primary it would be flat with the wall as in the diagram.
If carraige is 16", and panel is 48", then the carraige will go from 16" from the left edge of the panel to 16" from the right edge of the panel. The means the right edge of the carraige will be 32" from the left edge of the panel, meaning it'll stick a minimum 2" over the right edge of the wall, which you say shouldn't be a problem, but I think would look pretty hideously ugly (it's actually a double glass french door 'behind' that overhand so you're not only seeing the back of the panel (no way around that), but would very clearly see the overhang, which I don't want.
So this is exactly why I was wondering if the mount's articulation would let me get that additional 3-4" offset, without having to fully pull it away from the wall, or without having to angle it.
I updated the attachment to better reflect the dimensions. So basically I want to be able to have that lateral offset between the carraige and the mounting place 'taken up' by the articulation arems, and I'm wondering if this'll do it.
Or should I look at the Peerless or some other mount? A similar mount but with a narrower carraige (<= 10" rather than 16") would do the trick. The Peerless (from my measurement off the wall at the Costco Home) has it's right-most mounting 'holes' about 4.5" to the right of center of the mounting plate, but the wall plate is only 20" wide, so the attachment center would be 30-(20/2)+4.5 from the right edge of the wall, or 5.5" from the edge, or 30-5.5 = 24.5" from the left edge of the monitor, which would JUST make it (with the mounting plate exactly at the corner of the wall, but I'd want to move it a half inch left, as I have rounded rather than square corners on all my drywall corners), which would cause it to just scrape.
I can more easily see how the articulation on the Peerless would work in this case, but to me it doesn't look like as solid/stable a mount for a heavy panel (the Philips 47PF9441D
is pretty heavy) with all the weight on that one joint which is going to be heavily torqued, versus spread through two parallel joints like on the Sanus. It also looks like it's designed to be centered over the two studs, so depending on where my studs are exactly, I might not be able to mount it nearly as close to the edge, like I probably could with the Sonus that has a larger wallplate that'll likely cover trwo studs anywhere within its size range.
