A:Answer Thank you for a great question on our SmartCast™ M50-D1!
This display can accept 4K@60Hz through all HDMI ports. However, this at differing chroma subsampling rates, pixel clock rates, and color bit depth. HDMI port 1 has a pixel clock rate of 600MHz, and can accept up to 4K@60Hz with 4:4:4 Chroma with 8-bit color, or 4:2:2 Chroma with 12-bit color. HDMI ports 2-4 have a 340MHz pixel clock rate, and can accept up to 4K@60Hz with 4:2:0 Chroma and 8-bit color.
If you have any questions or concerns, we encourage you to reach out to our Support team at 844.254.8088. Thanks again and have a great day! -Collin
