The 
Steam Deck™ is a handheld gaming computer from Valve that uses SteamOS. It's allows you to play PC games with Linux-based Proton compatibility layer (for Windows games), or Linux games natively. The original model (also referred to as the LCD model), was first released in February 25th, 2022.
Almost all Valve games (such as Half-Life 2, up to Portal 2) have been updated to natively support all of the Steam Deck's functionality (such as controller layout and bigger menu UI for the small screen) via an update released in 2021-2022 respectively, marking the game compatibility with the Steam Deck as 
Verified. Half-Life 2 and Portal comes with entirely new menu UI (Gamepad UI) which makes it scalable on any resolution (including 4K or higher), while also can be easily navigate using a controller, compared to which become smaller if you run the game on higher resolution.
There is a expansion for the Steam Deck, the Docking Station, which adds more extensibility to your current gaming setup, allowing you to connect your Steam Deck to your TV, Monitor, etc... up to 1440p@120Hz or 4K@60Hz using the DisplayPort or HDMI, and also allows you to connecting your USB devices and Gigabit Ethernet to your Steam Deck.
An OLED model was announced on November 9th, 2023, which was later released in November 16, 2023. These models replace the previous 2 higher end LCD/original model. Furthermore, a Limited Edition version of Steam Deck OLED, which have a translucent case, was also available alongside with the normal OLED model, through it is only available in US and Canada with limited quantities. The OLED model, by it's name, featured a OLED screen (which have higher contrast ratio and deeper black level compared to LCD), plus better battery life, faster Wi-Fi, better thermal design, and much more.
