All good points and ideas. I have large subwoofer(s) and vertical centre channel speaker located in the front area preventing any option of the TV easily moving up and down option in front of the screen (although subs could be moved).
If I swing the TV to the side that would require a fancy mechanism and it would take up additional wall space on the left (right side has a window). If I roll the TV back and forth, where does it go when not in use?
Right now the TV is stand mounted but I have an amazing wall mount I can use which allows the TV to sit against the wall when the PJ screen is there and then the tv mount can bring the TV 20" out from the wall if necessary which is why I was thinking of going with TV on wall and screen swinging up when not in use.
I may get a screen with led lighting behind it. I could be use the screens led lighting while watching the TV if the screen is behind the TV (either for increasing contrast or simply for providing some room lighting when you have to get up and get refreshments or use the washroom)...or simply to have the led lights useable when not watching either the pj or tv. In either setup option (moving the TV and screen stays put or wall t TV and move screen) I can mount the TV and PJ screens at proper distances from the viewer.
Although I like the above idea, the more I think about the design aspecit, I think it may be easiest to use the TV wall mount I have now, and then just build a flat swinging wall.
Anyhow, if somebody has any cool links or ideas for articulated swinging boom like TV mounts, feel free to comment.
thanks for the feedback...stay tuned
