You will see a sharper image. But first, check if your streaming subscription has 4K. You may need to upgrade your subscription. Next, you’ll want to make sure you have a compatible device for your streaming service, such as a 4K smart TV, tablet, PC, laptop, gaming console, or media player like an Amazon Fire Stick, Apple TV box, Chromecast, or Roku stick. Your device must support HDMI 2.0 and HDCP 2.2. Install the streaming app directly on your device.
Your internet speed is also important; the faster the better. While Netflix suggests a minimum of 15 Mbps, Max recommends a faster 25-50 Mbps for the best experience, as does Apple TV Plus. You can also go a step further and check the bitrate while your video is playing.
Stream titles tagged with the 4K icon in your app. Depending on the streaming service or your device, some videos may not look as sharp in 4K, but you can check your device’s display settings to see if it’s set to “high resolution.”
