Here's why HDR, not 4K, is the most important upgrade for your next TV

• "4K" is the latest buzzword with TVs.
• Most advertising would have you think that 4K is akin to the leap we made from standard to high-definition TVs.
• Since HD made everything clearer, more pixels should only make your content look better, right?
• The problem: That isn’t totally true.
• Instead, when you're buying your next TV, there's another feature you should be more focused on: HDR.

Standard definition (SD), high definition (HD), and 4K (or Ultra HD) refer to a characteristic called resolution, or the number of pixels (or tiny display bits) that make up a display.
