Ask HN: Good Cheaper Alternatives to Apple Thunderbolt Display?

It's time to change my 8 year old monitor. I use a chinese make monitor that is really good, but sadly doesn't have HDMI or thunderbolt/USB options.

Looking for a 4k, 27inch monitor, with at least HDMI/USB-C connectivity.

Apple displays are great, but they are expensive. Any alternatives you would recommend?

(P.S. Not looking for Ultrawide monitors)
