Fiber Connections and Display Loading
Each optical port copies the data from the eight Gigabit outputs. These copy outputs provide an optical transmission path; they do not add another independent LED loading capacity. The source input limit of 4096 × 2160 at 60 Hz is separate from the 5.2-million-pixel screen load.
Use the HDMI output to preview the screen program and Wi-Fi for wireless PC software control. Maximum width and height are separate limits within the total pixel capacity. Infrared remote control is available as an optional configuration.
