While the AT-HDVS-200-TX supports 4K pass-through (up to 4096x2160 @ 60Hz with 4:2:0 at 8-bit max) the AT-HDVS-200-RX it's typically paired with can support up to 1920x1200 due to its built-in HDMI scaler. As such, the AT-HDVS-200-TX can be used to pass 4k signals when paired with a receiver such as the AT-UHD-EX-100CE-RX-PSE or when used on the input side of switchers such as the AT-UHD-CLSO-824.
