M1/M2 only has 1 native HDMI pixel pipe in any form, I think? Apple uses the HDMI PHY to drive the screen on tablets, and the screen on laptops. Base-tier M1/M2 also only have a single displayport pixel pipe, and Pro/Max get +1/+2 respectively.
The base-tier chips are designed as high-volume tablet chips first and foremost, with ultramobility crossover capability.
Using DisplayLink or certain kinds of thunderbolt multimonitor are possible while running outside the pixel pipe or running multiple monitors on a single pixel pipe (this is not MST which is multiple pixel pipes on a single stream). But yeah it's ugly especially on a base-tier processor with this eating cycles/dumping heat. You're running the hardware encoder at least.
Discord had this weird error if you tried to enable the screen/audio capture, it tries to launch something and fails and the solution is you need to manually install "airfoil" because it's an audio capture module that discord licensed. you don't have to fully install it but the audio driver is the part that discord uses and that goes first (has to be allowed as a kext, ie non-secure mode). theoretically a kernel-level capture like that could be a ton faster than userland, I think that's the on-label use of airfoil.
