The GPU supports a range of graphics APIs, including OpenGL ES 1.1/2.0/3.2, Vulkan 1.0 and 1.1, and OpenCL 2.0. The embedded video CODEC supports hardware decoding of standard video formats like H.265, H.264, and VP9 at 4K@60fps.

One of the key features of the Saylor is its support for three independent video outputs. These include HDMI (up to 4K x 2K@60Hz), LVDS (up to 1920 x 1080@60Hz), and an eDP 1.3 (up to 4096 x 2160) interface.
