Space is always at a premium in the home and office, but we always want our television screens to get bigger and look more realistic. LG's OLED solves all these problems with their 65-in "picture-on-wall" 4K HDR Smart TVs. With a width of a mere 3.81 mm and weight of 17 lb., you can mount them on any wall with magnets. They're pricey, for sure, but they can be more than a luxury item to trick out your home theater. While it looks like it belongs in a boardroom, it can be easily moved anywhere from remote sites or trade shows, and still provide the most realistic image quality available.
