Question: is all ps4 pro 4k?
Answer: You can only get dynamic 4K with a PS4™ Pro system connected to a 4K compatible display device with a Premium HDMI cable. Ensure you enable 4K on your PS4™ Pro system, 4K compatible display device, and any other device between your PS4™ Pro and 4K compatible display device (e.g. 4K compatible AV receiver).
