Unfortunately, you must select carefully any monitor that you purchase, and the cheapest models are unlikely to be good choices.
I am using 2 good Dell 4k monitors. One is 1-year old (U2720Q), but the other (UP2414Q) is more than 5-year old and it works as well as in the first day.
I don't buy a lot of computers, so this can change at any time without me noticing, but: I think there's basically two Dells. There's the Dell that sells the cheapest equipment you can buy. This Dell sucks as much as anyone else. Don't expect miracles. Then there's the Dell that sells upscale gear. This is usually pretty good, or at least has the ability to be pretty good. I have appreciated the ready access to service manuals and such, too.
I say this because it's unwise to hear that Dell has pretty good gear, then go to their site and buy the cheap stuff. It isn't necessarily any worse cheap stuff than anybody else, but it's not what people mean when they say Dell can have pretty good gear.
Purchased U2720Q after reading through a number of rave reviews and can definitely vouch for it. Excellent 4K image quality and works well with MacBook. It's only the monitor though, so no webcam or audio speakers.
Me too but with Samsung. I bought a cheapish 34-inch curved monitor that had great reviews, but it has almost as much light coming through gaps in the rear housing as the screen. Text looks like crap on its "not quite retina" resolution, especially when it's next to a retina macbook pro, although videos look very nice. I really do wish Apple would make a monitor more reasonably priced than the Pro Display XDR.
