    Recently bought a Dell u2515h and using it with a 2013 rMBP. Besides the slightly fuzzy text that other people have mentioned, everything on the screen is much, much smaller. I can't drop the display settings to anything lower than 2560x1440 because that defeats the purpose of buying this monitor.

    Is there a trick to increase the overall size of the display without losing resolution? I know I can zoom in to programs but I have to do that on a program by program basis, and even a tab by tab basis in Firefox. Not ideal.

    Im thinking buying this monitor too but what is the term fuzzy text that are you talking about?
    Can you post some photos, please ?

    Hi. Me again (from your other thread).

    It would seem like you want to turn on HiDPI mode for external monitors. Below are some links that DO NOT work for me. I'm just putting them for your reference.

    The second link shows what you could be seeing, but the only HiDPI mode you will see is a true 2:1 HiDPI mode (2x2 physicals pixels drawing one screen pixel), which means you're getting 1280x720 (which is rather useless IMO) but it'll be retina smooth! In other words, you're stuck with HiDPI at 1280x720, or blocky interpolation at the other resolutions.

    Or in more other words, you have three choices:
    • native (2560x1440)
    • interpolated (even more 'fuzzy'!, eg: 1920x1080 or lower)
    • HiDPI (1280x720 running at 2560x1440), if you can get that setting to appear.
    I'll reiterate what I indirectly alluded to in the other thread: you're spoiled by the retina screen.

    Also, if you think text is fuzzy on OS X, Windows will make your eyes bleed.

    As a U2515H owner, the only acceptable resolution to use is 2560x1440. You can run it at native 1440p, but like you say the resolution is too small for anyone without excellent vision. The alternative is to use a program like SwitchResX and run the U2515H in 720p HiDPI mode. The monitor will still run at 1440p, but the desktop space will only be 1280x720. You will get a super crisp display, although not as good as the rMB/rMBP. Running in any other mode is a waste and will have worse image quality than say a native 24" display running at 1900x1200, such as the U2415H. In hindsight, the U2515H only makes sense for PC gamers or Mac users with 20/20 vision. I really wish I'd gone with the U2415H or the U2715H...
