I speculated a few months back that what the world needs is an Atmos soundbar. The industry must have been listening, because we now have at least two such products, one from Samsung and the other from Yamaha. I haven’t heard the Yamaha, but the Samsung HW-K950 was being demonstrated at this year’s CES...
A photo shot with a point and shoot camera, viewed on your computer monitor can't really convey how fine this LG Signature 77-inch flat screen OLED looks in the flesh, but this shot from a short NASA video used for demonstration gives you a fair idea.
This edge-on shot shows just how thing the flat (not curved) LG Signature OLED display really is. As I noted in the LG press conference report, it's less than 2.6 mm thick. It does thicken out a bit more near the bottom; the electronics have to go somewhere!
Both Samsung and LG were showing huge 8k displays (Samsung's is shown here) and drawing crowds (I couldn't get near enough to LG's to shoot a photo!). While clearly technological demonstrations (with 16 times the resolution of 1080p "Full HD,") someone in Korea thinks this would be a nifty idea. But on the size sets most people buy, I'm not at all sure, apart from the Wow factor at a CES.
For those who can't position a video projector in the usual locations, LG offers the Mini Beam PF1000U at $1399. Said to offer 1000 lumens, it can be positioned close to the screen or a suitable wall as shown here.
