The SHIELD TV is the clear winner among Android TV devices, even if that is a very short field. The high-powered set-top-box gives a better experience than both the Nexus Player and the Razer Forge TV... which remain the only other stand-alone Android TV devices available. Today the SHIELD gets even better, because NVIDIA is pushing out the Marshmallow update to its hardware. NVIDIA updates usually go out all at once, so if you own a SHIELD, you should be able to start the download right now.

The biggest addition for the SHIELD is adoptable storage, which lets users reformat a MicroSD card into semi-permanent primary storage that can be used to download apps and other files directly to the device. With the base model's measly 16GB of storage space, and the gigantic file size of many SHIELD-exclusive games on the Play Store, easily adding 64GB or more to the SHIELD with a handy MicroSD card is a godsend.

In addition to the other 6.0 upgrades that come from AOSP software, NVIDIA has added a few extras as outlined in the GeForce forum post:

  • Access the power menu on the home screen by holding the Back button.
  • Seamlessly switch between surround sound and headset audio in Netflix app.
  • Added wireless support for SHIELD controller when charging via USB, including headset audio and voice search.
  • Improved color support for YUV 4:2:0 video playback.
  • Option to set 1080p 60Hz resolution on Ultra HD TVs.
  • Option to set RGB Full Range. Go to Settings > HDMI > Dynamic Range.
  • Improved support for Denon receivers.
  • The upgrade weighs in at a little over 800MB, which shouldn't take too long to download and install on a decent connection. Get after it.
