- panda88888 4y agoWell, the 13” M1 MacBook Pro is basically the Air with a fan and more ports?
- masklinn 4y agoYep, though that's really more of a question of chip: the M1 only supports two displays, for the laptop that includes the internal one (the Mini only supports two displays, and one only 4K via HDMI).
- 411111111111111 4y agoTo be fair, several of my work laptops had a similar sentence in their user handbook, but two monitors were possible if you connected the wires before booting the laptop. Really strange limitation, as it never scaled with bandwidth - so 4k 90+Hz was doable, but 2x 1080p60hz wasn't.
- p_l 4y agoSome intel laptops (Ivybridge chips definitely, sandy Bridge probably) had such warnings because officially the chip couldn't support running three displays due lacking enough clock generators. Given the almost-analog nature of HDMI and naive LVDS, this meant trouble. Thing is, Display Port has much more different physical layer derived from PCIE, and so connecting two displays by DP and running internal screen with LVDS worked just fine.
