Over the past several years, 4K content has become more readily available. With Google Stadia on the horizon, and plenty of 4K television shows and movies on streaming servies like Netflix, more companies are betting on 4K and HDR, and a big part of that is the availability of affordable 4K TVs.
While 4K (like many great advances in tech) was once prohibitively expensive, you can pick up a 55-inch TCL 4K TV with HDR on Amazon right now for $399. That means you can get a bigscreen 4K TV and a 4K-compatible gaming console (PS4 Pro/Xbox One X) for less than $1,000.
