MAC RETINA DISPLAY MONITOR VS 4K MONITORS PRO
Default scaled resolution for current Macbook pro 13 is 1440x900, which results in around 128 PPI on 13.3 inch screen.On an 16 inch display, this results in 132 PPI. Default scaled resolution for Macbook Pro 16 is 1792x1120.I tried to explain in following sub-topics: Ideal PPI for laptops and desktop screens are differentįirst of all, Apple adjusts its desktop monitor default PPI values to look like 110 PPI, however for laptops, they tend to use higher PPI values. In summary: after lots of researching and testing, I found an LG 27 inch 4k display to be the best balance from price/performance point of view for now. I had to make a similar decision for myself. Is there a list of complete resolution and screen size pairs available which provides perfect scaling on macOS? For example, would a 1440p or a 4K display that is 27 inches provide good scaling? These two resolution-screen size pairs I can thus add to my list. I assume that a 1440p display that is 27-inch will also provide perfect scaling on macOS, since it is exactly half the resolution, but exactly the same size of a 5K display. It turns out you'll only get exactly the same size with very specific panel size and resolution combinations (as described below).

This was leading me to a lot of confusion.

Edit: the sizes of objects on my internal screen and external monitor are not exactly the same. It scales perfectly, which makes sense since it has exactly half the resolution which having the same size.
MAC RETINA DISPLAY MONITOR VS 4K MONITORS 1080P
I have a 24-inch 1080p screen, which is the same size but half the resolution of the 4K LG display. Older, non-retina displays have a PPI of around 110. For examples, the 21.5 inch and 27 inch iMacs, all of the retina MacBooks and MacBook Pros, the Pro Display XDR, and both LG 4K and 5K displays. I noticed an interesting trend: most Apple displays have a pixel per inch (PPI) value of ~220. To test this, I tried looking at current display offerings that Apple provides. Otherwise either the scaling or sharpness will be off-with certain combinations of resolutions and screen sizes, you would need to choose between proper scaling (how large something appears on a native screen versus the external screen), and good sharpness (how clear the text and images appear on the screen).

However, I have heard that not all monitors will provide these two things-the monitor needs to be a specific size and resolution.
