I'm curious why you need 5K@27 for 3 columns. I have 2x27" 4K LG's and they comfortably fit. The effective DPI may be higher on 5K at 27" than 4K at 27" but at a reasonable distance I fail to see any difference (approx 220ppi vs 170ppi at 3 feet).

I currently use a 24" at 4K and to fit 3 columns I need to use a smaller font size, which makes the code hard to read. I used to have a 27" at 4K, and indeed you can fit 3 columns then, but the blurry/jagged fonts annoyed me. 4K really isn't enough for 27". My conclusion was that I need exactly 5K at 27" (and not larger, because then you have to turn your head to see everything) for coding.

  Interesting, you must have excellent eyesight 170ppi at arm's length and I can see a pixel or any jaggedness. I agree with you about size though running two 27" (on VESA mount arms) is the max I'd want for comfort as it was I had to get a 80cm deep desk to sit slight further back. https://i.redd.it/tctxa7hs16l21.png https://i.redd.it/tctxa7hs16l21.png That desk is 120x80 and the monitors still over shadow it.

5K at 27" enables you to use 2x scaling which is much lighter on your hardware. Scaling 4K at 2x leads to a sizing which looks like 1080p (just much sharper), which may be too large depending on your distance from the screen. Using anything but 2x scaling will tax your hardware, slow down the computer and blur the image.

  Ah Mac. I'm on Linux and I just use fractional font scaling (1.5 usually) and everything works fine and it has no performance impact I can discern across AMD RX at work, intel hd or rtx2080.

    While it's true that fractional scaling works differently on Linux and Windows, it's my understanding that many apps don't handle scaling well, or at all, over there. Meanwhile on macOS basically any app scales properly - I think I have never seen one that doesn't. You can use fractional scaling on a mac, but in that case your whole output will be rendered in 5K and scaled down to the target resolution, which is of course an intensive task - I wouldn't recommend it and instead always use true 2x scaling.
