I walked into an Apple Store and asked, “What monitor/TV should I buy such that my AppleTV remote can control the volume and be the only remote I need?” The geniuses shrugged. I asked, “What brand are these displays in the store that are connected to the demonstration AppleTVs?” They shrugged. We turned them around so I could see the backs of the monitors and I wrote down the model numbers.

It is far from obvious to me.

I give up. I couldn’t find that list. Where do I look?

It would be useful to know what brands to avoid.

There's probably a list somewhere on the internet but I've never seen one. When I went monitor shopping six months ago, I used the Macrumors forum heavily. There are long threads on the forum for monitors which didn't work well because of edid or other factors. That's how I ended up with an Asus ProArt 4k instead of the Dell I initially wanted. Everyone complained about how MacOS handled the Dell but no one had a bad word for the Asus.

Though it was a little frustrating to me that I had to monitor shop in the first place. I bought an MBA to start some iOS projects. I wanted to use my still great 1080 IPS Dell screen that I had used for years with Windows and Linux. But MacOS looked absolutely horrid on it. I know MacOS prefers higher resolution screens, but I was surprised it couldn't manage to handle a ridiculously common resolution.

All the Dell monitors I've ever tried have worked just fine. Including the lower resolution models. On those, you don't get the Retina crisp display, but it still works.

Of course, I avoid HDMI like the plague. I only use DisplayPort unless I have no other option, and then I don't hold out much hope that the display maker did anything right.

Oh, ok, so the OP should, as a consumer, know about all monitor standards before purchasing one. Good to know.

Let's shorten that to: buy reputable monitors, from brand names you recognize. You wouldn't buy a no-name car.

You underestimate my cheapness and lack of caring about my car. Bring me a Chinese cherry car and I'll replace my 10 year old Suzuki

This seems like bad advice. A little bit of Googling for solutions to this found this thread[1] which identified (old) Dell monitors as being one of the problems.

That's basically the current state of computers. Some vendors care more than others. I'm sure there are ASUS monitors out there that don't work correctly with ASUS laptops, but if you buy an Apple monitor it probably works with an Apple laptop from the same vintage. That's just how things are. The market seems to prioritize "new" over "good". Doesn't mean you can't do some research to get "new" and "good" though.

Yup, the solution is to not buy apple laptops.
