Ask HN: Anyone know workarounds to MacBook Air M2 missing dual-monitor support?

I bought a second external monitor to pair with my existing one, only to find out my M2 MacBook Air won't support it.

I found workarounds[1] online such as "DisplayLink", which requires custom drivers and a $127 external adapter, and "SiliconMotion"[2] which I'm unclear on how to use. I've seen people on Reddit say the experience barely approximates the native feel, with features such as "Night Shift" not being supported and noticeable lag, even for office use, which is what I plan to use it for.

I made sure to purchase the adapter with the most advanced chipset available (the Startech device[3]) but I am worried the experience will be subpar. I chose an adapter to DisplayPort instead of HDMI thinking it might perform better but that's to be seen.

Short of buying an M3 Pro MacBook Pro, which is obviously off the table, do I have alternatives? Are there any homebrew solutions that work around this out there?
