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.

String together three of Samsung's 27-inch curved widescreen computer monitors and what do you get? An immersive gaming experience if the game itself is designed for it.

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.
