https://arstechnica.com/gadgets/2024/03/macos-update-will-let-the-m3-macbook-pro-work-with-two-external-displays/ > One longstanding limitation of Apple's most basic Mac chips—the no-adjective M1, M2, and M3—has been their inability to work with more than a single external monitor at a time. This was one of the only ways in which the Apple Silicon era has been a step back from the Intel era, where most Macs supported at least two external displays, plus the screen built into the MacBook Air or Pro you were using. (Would an integrated Intel GPU actually work well with that many screens connected? Usually not. But at least you could try.)
