There are listed only 2 models on my favorite comparison website:
LG UltraFine 4K 24MD4KL-B, 23.7" - 3840x2160, 16:9, 186ppi - https://www.rtings.com/monitor/reviews/lg/ultrafine-4k
NEC MultiSync EA244UHD-BK schwarz, 23.8" - 3840x2160, 16:9, 185ppi - https://www.tomshardware.com/reviews/nec-ea244uhd-4k-uhd-24-inch,3975.html
If you could go with 2560x1440, 16:9, 123ppi there are a lot more and much cheaper options: https://geizhals.de/?cat=monlcd19wide&v=e&hloc=at&hloc=de&sort=t&bl1_id=30&xf=11939_20~11940_24~12018_110
