In addition to Google Stadia and GeForce Now, LG will soon add Utomik and Blacknut. The company is also rolling out a new 'Gaming Shelf' on its 2021 and 2022 LCD and OLED models.
Earlier this year, Samsung in a some regions launched the Gaming Hub with Xbox, Google Stadia, GeForce Now, Utomik and now also Amazon Luna.
LG's response is the Gaming Shelf, which is a new gaming-focused section in LG's webOS user interface. Gaming Shelf is rolling out globally to bring cloud games to the forefront for owners of recent LG OLED TVs and LCD TVs running webOS 6.0 (2021) or webOS 22 (2022). LG is not upgrading its Smart TVs to newer generations of webOS after the sale.
Update: LG Korea confirms to FlatpanelsHD that the Gaming Shelf is a server-side update for webOS. It does not require a firmware update of the TV.
At launch, games from Nvidia's GeForce Now will be highlighted on the Gaming Shelf, and soon you will also see highlighted games from Google Stadia and other gaming services.
