Huh, very interesting. OK, I just grabbed my loupe to make sure I'm not missing anything, and pulled up an app in dark mode (so ringing should be more visible) on my MBA M4. I'm using its built-in display. I've cycled through all 4 available resolution settings in Display, and absolutely zero artifacts or ringing. Then tried connecting to my LG UltraFine 4K which connects over Thunderbolt, that gives 5 resolution settings instead of 4, and zero artifacts/ringing on any of those either. So I have no idea what's going on. I don't doubt that you're seeing it, and it's there in that Reddit photo. But maybe it's something specific to external monitors over a certain connection type or something? Seems very strange that Apple would use a different downsampling algorithm under different circumstances though. I'd normally assume the most likely culprit would be some kind of sharpening setting on a monitor, as that can absolutely cause the type of ringing seen in that Reddit photo. But on the other hand, if you're testing it right now and not seeing it at native 2x, then that would seem to be ruled out, at least in your case. Maybe it's some kind of resolution negotiation mismatch where it's actually the monitor applying a second scaling that has ringing, since monitors can accept signals that don't match their native hardware resolution?

IMO, for Mac, text looks good only on Apple monitors. I'm using a MacBook Pro M1 connecting to the LG Ultrafine 32" 4k monitor. Text on the laptop monitor looks very good, but looks terrible on the 4k monitor. It is said that it's because of no ClearType feature in Mac OS. If I want a small machine like the Mac mini, I'll pick up some Chinese mini pc on Amzn or an Asus mini pc (for a better brand name) or an Intel nuc (the most expensive in the mini pc line). Those mini pc's can connect to at least 2 4k 60Hz monitors (for the ones < $300). The $400+ mini pcs are usually able to connect to 3 4k monitors. They can go with 16GB or 32 GB memory easily. Only the $2k M2 pro mac mini's can connect to 3 monitors and have 16GB ram. I think all of Apple products are very durable. You can stick with 1 mac mini for 10 years or more. If you're not very unlucky, you can use a Chinese mini pc for 3-4 years. When it dies, you can have a newer, better (in configuration) Chinese mini pc for the same price.

Similar problems with my M1 air. The Dell monitor I had connected in a weird color mode YCbCr which make the screen look washed out and everything was blurry with 1440p. Then I found out about the no 2 external monitors problem after I had already bought it. Ended up buying a LG 4K ultrafine which works great and using this to drive my 2nd vertical 1080p: https://www.hypershop.com/products/hyperdrive-dual-4k-hdmi-1...

Had a similarly frustrating experience trying to connect a new gaming PC to a LG Ultrafine 4K. The all-USB C aspect of the monitor was fine when I only used it with my Macbook, but made it terribly painful to use with anything else. In the end I found a HDMI to USB C dongle which worked, also included a plain USB 2.0 cable for audio. Apparently I was ‘lucky’ to have the 4K rather than 5K, because, from my research at the time, nobody knew of any dongles or cables that would support the latter at full resolution (I think this is the same issue as in your article)

I’ve had 5 ultra fines since they were released in 2016/15ish, both 3x4k 21.5”, and now 2x5k 27”. Never experienced any issues, build quality is quite high in my opinion and the stand is surprisingly solid, much better then my Dell UltraSharps and LG UltraWide. Of course not at the level of the Apple Displays but they are really outliers in the industry.

The best option was the LG UltraFine 24” 4K, which sadly was discontinued years ago. In my opinion a QHD 23.8” panel is the next best option for developers (any M-series chip handles scaling without issues); I find the common 27” and 32” at 4K a weird spot - slightly too large, slightly too low resolution – and 5k+ options are still rare.
