Samsung Q9 88-inch 4K TV

I'd say the most common top-end TVs come in 55-inch and 65-inch sizes. Above that there isn't as much choice, and the price escalates quickly. But Samsung feels there's a market for an 88-inch TV, and as The Verge points out, Best Buy just started selling it for an eye-watering $19,999.99.

The TV in question is the Samsung Q9. It's a 4K 2160p LED Ultra HD display with High Dynamic Range (HDR) and Quantum Dot technology. There's built-in Wi-Fi, four speakers, two woofers, and DTS Premium Sound 5.1. As for connectivity, you get four HDMI ports with guaranteed support for Ultra HD Blu-ray players, and three USB ports.

Watching fast-moving action such as sports or movies is helped by the inclusion of Samsung's Motion Rate 240, which translates to up to 120Hz refresh rates. The display is also "certified 100% color volume," meaning over a billion colors are apparently possible.

Even though this TV is huge, it supports easy wall hanging and includes a thin optical cable allowing you to reduce visible wiring and hide other connected tech such as a Blu-ray player from view.

Such an expensive TV really does beg to be protected, but that protection does not come cheap. Best Buy is offering five-year Geek Squad protection, but it adds another $2,099.99 to the price.

I think even if you are tempted by this 88-inch model Q9, it's probably the logistics as much as the price that influences the decision to buy. Without the stand the display measures 77.9-by-44.5-by-1.2 inches and weighs 160 pounds. So your first two questions should be: will it fit? and can I afford it? If the answer to either of those questions is "no," don't worry, there are plenty of great TVs out there to choose from.
