The Tech Specs site says the laptop simultaneously supports full native resolution on the built-in display and:
Up to two displays with 6016‑by‑3384 resolution at 60Hz at over a billion colors
Up to four displays with 4096‑by‑2304 resolution at 60Hz at over a billion colors
Since four 4K displays can be supported, I am assuming one 8K display can be supported. But I'm wondering if this can be done using one cable. The laptop supports two 6K displays, but this requires two cables, one for each display. Does this mean 8K resolution through one cable is impossible?
