You're about to feel better if you've been holding back on buying a new TV. The HDMI Forum has unveiled a new specification for its namesake video connector, HDMI 2.1, and there's enough here to make enthusiasts happy. It now supports both very high resolutions and high frame rates. In particular, you can get 4K at a speedy 120Hz, and 8K at 60Hz (when 8K sets are ready). You'll even see 8K with high dynamic range, although you'll need new 48Gbps cables to experience this and other high-bandwidth features in all their uncompressed glory. Thankfully, there are some upgrades that shouldn't take years to reach your living room.
