Herm,
There is an auxillary input on the Jensen.
For overall dimensions, the LG is only slightly smaller the the 650 Samsung. I did consider that, but when it came down to it, I like the look, picture, and connection options of the Samsung better. And I've had good luck previously with Samsung products.
For the mount, I'm still shopping and looking at some mount options. My issue is that all the arm models I've seen do not have a locking feature. So, run into the issue that Dunphy's did with their's and have to use a bungy cord to hold it in place while travelling. I also do not need an arm as long as the Dunphy's chose, as I will not use it for a computer screen over the dinette table. I mainly want the option of either watching it in the corner(like presently installed in Olivers) or swing it to a central location in front of the window above the dinette. I'm currently looking at the 4N1 model from Omnimount.
The other option I thought of the other night is to keep the mount that Oliver uses and then add a second base of the same mount centered above the dinette window. Then could simply unlatch the monitor and move it to the other location when needed. Then wouldn't have to deal with bungy cording the monitor at all. I don't know, still debating and will decide in the next day so that I can finallize my invoice with Robert.
