To implement 4K / 8K UHD video playback:

  1. Check that the TV supports

    1.1 4K UHD video playback using the isUdPanelSupported() method of the ProductInfo API:

    • isUDPanelSupported()
      true : 4K or higher resolution supported. It returns true when either 4K or 8K, or both are supported on the TV.
      false : Not supported (up to FHD supported)

      if (webapis.productinfo.isUdPanelSupported()){
        console.log("4K UHD is supported");
      } else {
        console.log("4K UHD is not supported");

    1.2. 8K UHD video playback using is8KPanelSupported()method of the ProductInfo API:

    • is8KPanelSupported()
      true : 8K supported
      false : Not supported
      if (webapis.productinfo.is8KPanelSupported()){
        console.log("8K UHD is supported");
      } else {
        console.log("8K UHD is not supported");
