Over-the-Air Broadcasts in 4K and HDR? It's Here (Sort Of)

If you want to save money by ditching cable and the endless streaming service subscriptions, you are in luck. In most US cities, NextGen TV is broadcasting already. Formerly known as ATSC 3.0, NextGen TV promises 4K HDR, more channels and even better reception. All you need is an inexpensive antenna, and if your TV doesn't support it (many new and recent models do), there are a number of devices you can connect via HDMI like any other source.

The rollout of NextGen TV has been fairly slow. While there are broadcasts in nearly every major city, those aren't typically in 4K or HDR, though that seems to be changing. The good news is that it's extremely easy to bring NextGen TV into your home, so even if it's not 4K, it is free HD TV, including more news, primetime TV and sports. Here's everything you need to know.

For now, check if it's available in your area, or at least, when it's coming: watchnextgentv.com/markets. For more info including how it all works, check out Free antenna TV is getting an upgrade and it might be in your town already.
