For what it’s worth, this does not seem to present itself in all current 15/16” chassis models. I use my 2018 2.6GHz i7 15” MBP with two 4K monitors plus the laptop monitor. It’s fine for me. (But I do believe you!)
If it’s useful: It’s fine here including reasonable loads on the video card, like a lot of GPU-accelerated terminals and pretty heavy use of a tiling window manager and Exposé window swishing. Or, say, Sketchup in a browser? Plus a pretty serious IntelliJ setup with the JVM’s stops pulled out, running ReasonML and C++ source compilation, and use of Docker.
It is sensitive to setup, and I can get it to spin its fans up. Docker is especially prone to wasted cycles. And I did seem to have to do some SMC resetting at one point because the fans were a little eager to get going. I also think it makes a bit of difference if I charge through the right-side ports rather than the left.
But the main point I’m attempting to make: I do think your case is solvable.
That said, I have felt that Apple are losing their way in some respects. The fact that there are fan issues with some machines and that it’s not clear how to solve them is a problem with these machines.
- MarkyC4 6y ago> this does not seem to present itself in all current 15/16” chassis models I think they're referring to the thermal throttling, and not the MBP forcing the discrete card when an external monitor is connected. As far as I know, there is no way around using the discrete card for external monitors (on my 2015MBP at least, I'm pretty sure the HDMI port is wired direct to the M370X). I've solved the thermal issues by using an eGPU (like GP suggests)
- Hamuko 6y agoI have a 2019 16-inch MacBook Pro connected to two displays via USB-C and DisplayPort through a Thunderbolt dock and it seems like it also forces it to discrete graphics. I'm not sure if I've ever seen it use integrated graphics when I'm docked.

- matthewdrussell 6y ago16" rMBP Pro with beefed up graphics running Dual LG 5K monitors When it works, its great which is about 50% of the time. When it doesn't and for no apparent reason, it will often reboot a couple of times (just when plugging in the displays). Sometimes the banding issue that the M1 Mac owners have described appears on one or both of the displays. A pretty frustrating experience.
- nuggien 6y agodo you have powernap enabled? i had this issue with random reboots when plugging/unplugging displays and disabling powernap fixed it for me.
- matthewdrussell 6y agoI do. Just disabled it, thanks for the suggestion. Already running discrete graphics all the time so no auto-switching.
