    Hi guys!

    I need your advice: what external monitor to choose if you have myopia?

    In my case, it's -2,5 (not serious) and I work without glasses. Thus, I stay very close to the screen: it's OK if I work on my MacBook Pro 15" Retina 2014 but I experience some troubles when switching to a big external screen.

    For e.g. I tried BenQ BL2711U 27" 4K UHD (3840x2160) and DELL P2418D 23.8"QHD (2560x1440) - these two are great but the screen space is too big, the elements and fonts are extremely small, I'm wasting time to move my eyes from one corner to another one :)) - literally, I'm lost in the screen.

    I tried DELL P2219H 21.5 (1920x1080) and it was comfortable enough by the sizes but the screen is too granular, I can see the pixels...

    I'm looking for 22-24 inch. monitor. Any recommendations?

    Also, I noticed that the scaling doesn't work nicely on external monitors: you can only downscale the resolution which makes the image awful and you can't choose between 'Larger text' - 'More space' option like on the native Retina screen. Is it a common issue for all ext. monitors?

    LG 24" 24UD58 4K. USB-C (with DP to USB-C passive cable).
    Best bang for buck high dpi screen.

    Run it @scaling 200% (retina mode).

    Since the native res is exactly the double in each direction of Full HD, when scaled @200% it is the equivalent of full hd on 24" which is very comfortable (I.E. big but not too much) and provides extremely crisp / sharp text.

    How to achieve it?

    Can you share screenshots with your settings, please?

    The either don't use a big external screen or wear properly prescribed glasses. The latter is my personal choice.

    Absolutely nothing that you do with the display resolution or scaling will correct for you not being able to focus on a distant screen.

    don't have a mac available right now, but you need to divide the resolution by 2 in each axis to get pixel-perfect retina 200% scaling .

    I.E, if you have a 4K screen @3840x2160, set to 3840/2 = 1920 ; 2160/2 = 1080 so, basically 1920*1080 virtual full hd but each virtual pixel is rendered using 4 (2 per axis) native hardware pixels.

    on windows it looks like that :

    on your mac, given the screenshot, you would select "scaled", "1920*1080" for a 3840x2160 screen; for a 2560 * 1440 screen, you would use 1280 * 720, ...

    for this 4K example, any other non-integer scaling ratio will introduce a blur / imperfections since software filtering needs to be applied to map non-integer pixels to physical pixels.

    Eg, @150% for a given axis it needs to form 1 virtual pixel using 1.5 hardware pixels... some information is lost in the way.

    got a mac hooked up,

    here is how it looks with the lg 24" 4K under mojave,

    note that checking "default for display" is the same that the 200% scaling obtained with "larger text" -> "looks like 1920 x 1080".
