It would help if we had a better idea about the orientation of the rooms -- the space you have available. I agree with those who suggested you consider swapping the functions of the rooms -- make the existing dining room the TV viewing room and move the DR table to another room (LR or FR). Failing that, is it possible to extend the feed from the security cameras to a location where you would actually want to sit and watch TV? Failing that, could you purchase a nice tablet for hubby that he can have with him anywhere in the house, so he would have ready access to view the security feeds? After all, I would think the need to view those feeds is momentary at best -- watch a movie, pause the movie to check cameras for a second, return to movie -- right? He's not going to actually sit there and watch the feeds for any appreciable period of time, I would think (although my father can sit for appreciable periods of time watching the Weather Channel, so what do I know?).

I suggest grouping whatever living room furniture you buy around the fireplace. It is what I did in my long living room (mine is wider than yours). Here are some layout suggestions: Before you buy any furniture, make sure you have the room to lay it out something similar to the above suggestions. Put tape on the floor, if you have to and make sure you have enough room to walk around the furniture. You can also try Basset Furniture and/or La-Z-Boy showrooms. They can help you with furniture arrangement and they do not charge you, like a designer does. For the TV, you could either get an entertainment center that will fit right or left of the fireplace or your could even mount your TV on the wall (I have 2 TV's that are wall mounted and I love it). When I was getting ready to move into my house 3 years ago, I needed brand new living room, dining room, and family room furniture. I shopped sales and I found my 2 sofas that are in my living room first at a furniture store selling La-Z-Boy furniture. I got lucky! The sofas were on sale for over 60% off and after choosing them, everything else fell into place. For the family room, I went to a La-Z-Boy showroom, found a reclining sofa I loved, and it was also on sale. I choose soft, neutral colors for it and two rocking recliners. We use this room to relax and watch movies on our big TV in the family room. I also suggest looking at rooms on Houzz and see what appeals to you, in style and color.

I'd put it on the long wall opposite the window and look into a low-backed u- shaped sectional with the longest side facing the fireplace, the middle part back to the window and facing the TV, and a chaise section next to the fireplace. That's exactly what I have in our house. The chaise section is for stretching out on, and allows everyone to still have the view of the pretty fireplace. We got a custom sofa, for about the same or less than you'd pay at say, Pottery Barn. It's deep and has plush chenille fabric, and it's the best for our rambunctious house full of teens, dogs, and guests. And it seats a lot of people. We also got a big square ottoman that lives at the end of the chaise, but can be pulled over to whereever needed. It's perfect for us. Of course, you'll need to tape off the room to see what will fit. If it won't fit, then please ignore my comment!!!

But to your point grapefruit, if the tv was in the bar area, the seating would be awkward for a family of 5. That’s why I’m looking for a solution that can add more comfortable seating for tv watching and possibly replacing current furniture with a sectional.
