That monitor is a 27" monitor with a resolution of only 1920x1080 pixels (typical of a 24" monitor).

Apple's been using displays with Retina-level pixel densities for a while, and if some of the things I have read about recent versions of macOS are true, Apple has made some changes that are not such good news if you are trying to use a display with a low PPI density. This article, for instance, indicates that in Big Sur and Monterey, there is a font-smoothing preference that is no longer accessible from the GUI - only from the command line. It may be gone completely in Ventura, for all that I know.

If you like the large size of text on a 27" 1920x1080 display (and aren't bothered by the loss of workspace which goes along with that), one possibility might be to get a 27" 3840x2160 ("4K") display and run the new display in Retina "like 1920x1080" mode. Then text would stay the same size, but there would be a block of 2x2 tiny pixels for every 1 large pixel that you have now. The operating system would use the extra pixels to draw letters in finer detail, and you would likely enjoy sharper text than you have been enjoying with the old monitor on the Windows PC.
