Question: is the hdmi with xbox one x 4k?
Answer: The current HDMI revision supported by Xbox One X right now, HDMI 2.0, supports transfer rates up to 18 Gigabits per second – imposing a limit of 4K (3,840 × 2,160 pixels) resolution at 60 Hz. HDMI 2.1 increases this limit to 48 Gbps, allowing for 10K resolution and 120 Hz at lower pixel counts.
