I've connected 27" Dell U2715H to MacBook pro 2012 and have a default resolution 2560x1440. It looks nice but the font size is waaaay too small, so I had to lose some of this niceness by scaling down to 2048x1152.

I wonder is this a usual thing people do? I know this kind of displays (27" 1440p) are popular as an external MacBook monitors. As far as I know, it's not possible to change the global font size. I can't imagine how people go along with this tiny text by default with 1440p.

UPDATE:

a good question came up in comments about what do I consider a tiny font size, it's a good point, here's how it looks (full screen snapshots):

  2. Scaled down 2048x1152: https://i.imgur.com/neyt4r1.png

My eyesight isn't perfect so I asked my colleague who wears glasses to take a look at it, he confirmed that it does look tiny

In my experience if you connect your monitor via HDMI it won't give the the font scaling options in System Preferences > Displays.

If however you connect via DisplayPort i.e. Mini DisplayPort to DisplayPort it should give you the options similar to these:

There used to be some hacks to trick the monitor into switching into HiDPI mode but I couldn't personally get these to work on macOS High Sierra, but using a DisplayPort cable rather than either HDMI or Mini DisplayPort to HDMI did resolve the issue.

  • A 27" Dell U2715H isn't a HiDPI monitor, though, it's standard resolution... & really they're crisp enough to read from the other side of the room at normal settings; so the question to be asked might be "What does the OP consider normal/tiny for a font?" – Tetsujin Aug 15 '18 at 11:00
  • That's exactly how I scaled my resolution i.imgur.com/yZVWAZc.png, I guess that's the same thing as on your screenshot. I connect my display via a DisplayPort. – csandanov Aug 15 '18 at 11:03
  • @Tetsujin it's a good point, I've updated my post with snapshots for comparison. I feel how my eye strain with the default 1440p font size – csandanov Aug 15 '18 at 11:15
  • I wasn't saying that it is but the HiDPI feature lets you scale the UI and font. – unknowndomain Aug 15 '18 at 11:18
