Use HDR Technology to Upgrade Your Viewing Experience, Explore the Different Options for Your 40-Inch 4K TV
HDR TVs

If you're looking for a TV with HDR, make sure to check out one of our three 40-inch 4K TVs. With a high contrast ratio, HDR TVs deliver more natural gradations. Built with a standard 10-bit color depth, they are able to display over a billion individual colors, providing enhanced subtlety of the shades and tones within a scene. They feature advanced pixel quality, creating better clarity in shadows and highlights. However, they produce very bright highlights, so they might be too bright on your eyes, especially when you're watching TV in a dark room.

HDR10 TVs

Get dynamic imaging by learning all about HDR10 for your 40-inch 4K TV. Make sure to check out a great choice here. Designed with a high contrast ratio, HDR10 TVs deliver more natural shades. They feature advanced pixel technology, which offers a much wider color gamut. Built with 10-bit color depth, they are capable of displaying over a billion individual colors, providing greater subtlety of the shades and tones within an image. They have static metadata, which works to set and maintain a constant tone for an entire film, as determined from the beginning of playback. Something to keep in mind is that they require special hardware, including a newer HDMI, in order to function properly. Also, these HDR10 TVs rely solely on static metadata, so there is one HDR "look" for the entire movie or show.
