NVIDIA SHIELD TV gets a new software update to SHIELD Experience 8.2.1 with tons of bug fixes

NVIDIA has once again put other OEMs to shame with a firmware update for its NVIDIA SHIELD TV range — including the original generation device from all the way back in 2015. Shield Experience Upgrade 8.2.1 doesn’t add a massive amount of new functionality over version 8.2 but rather addresses a lot of niggling bugs from previous editions.

The biggest change is for owners of the most recent (2019) versions. The IR capabilities of the SHIELD Remote have been updated to allow control of more third-party devices such as TVs, speakers, and projectors from brands including Monoprice, ONN, Sennheiser, and Tascam. Owners of older NVIDIA SHIELD TV models won’t find this functionality unless they upgrade to the 2019 style remote (which is backward compatible and will set you back around $30).


Other tweaks include adding a notification to enable AI-upscaling for streaming service GeForce NOW, better handling of sound when routed through a USB DAC or Bluetooth Headset, support to send IR commands as part of an Alexa command, and as you’d expect, security updates, in this case taking us up to August 2020’s security patch level. There’s also a fix for that annoying issue where the SHIELD would stop receiving IR commands from the remote, and the long-time issue of the NVIDIA SHIELD TV device not appearing as a destination for casting.

The changelog is impressively large, so we won’t dissect it all here, we’ve placed it at the bottom of this article for your reference. However, it’s worth saying again that, biannual revisions aside, this is all the same basic device that was launched in 2015, and to see it get another update, just a week after OnePlus confirmed it would only offer one upgrade for its latest Nord handsets, is a refreshing change.

Better still, it doesn’t take a lot of work to upgrade, as ever, you’ll get a huge banner on the home screen telling you what to do.
