![]() ![]() I prefer very sharp text but want to avoid really tiny text on a large display. what a consensus of others think is best. Reviews and commentary will help you avoid a clearly bad choice, but if you can try it yourself before buying, that will give you a better chance of getting what you think is best, vs. If the store will let you connect your own computer to a display unit (laptops are clearly preferable for this), then that would be even better. Other stores (Best Buy, Staples, etc.) also have display models, but with a much smaller selection. I know Micro Center has a lot of models on display. Ultimately, if you can, see if you can go to a store and see for yourself what a variety of different displays look like. Some want a larger screen for that many pixels while some prefer Apple’s “Retina” scaling to produce extra-sharp images.Īnd some would prefer an ultra-wide display (I’m one of those, but I really don’t want to get rid of a working display in order to put one on my desk). You may really like the look of a 5K display (whether Apple, LG or someone else’s). But I’d like to underscore the point that monitors are a personal preference thing. ![]() Your desktop will be rendered at that resolution, which will be sent to the display without any scaling (your display will up/downscale the image instead). This scaling should be done by the GPU, but of course, it means that it will consume some GPU resources (don’t know how much) that won’t be available for applications.īut if macOS doesn’t detect a retina display (or if you override the detection by option-clicking the “scaled” button), then you will just select a resolution from a list (received from the display). The various “scaling” options in the Displays preference panel will determine the desktop size, which will be rendered internally at some (pretty high) resolution, and then scaled to the display. But if you’re not mirroring (meaning the two screens show different content), you should be able to set the external display to whatever resolution you like.Īll that having been said, if macOS decides your display is a retina display, then macOS will (by default) output a video signal that matches the display’s native resolution. If you are mirroring a laptop screen, then that will of course, end up resizing its content to the external display’s resolution (which should be independently configurable). The GPU of any Mac should be able to generate whatever frequency (up to published limits, of course) the display says it can accept. There’s no such thing as “the Mac’s default resolution”. If you cannot find a resolution that fits your preference, just return it. Make sure to get your display form a vendor with a good return policy. But it’s not strictly a requirement to get 5K to run 27" well.Īt the end of the day, displays are a very personal thing. (This is why “retina” on iPhone calls for much higher ppi.)ĥK at 27" is nice because its native 5120x2880 (218 ppi) lends itself to be run at exactly half leading to the crispest display but still at a reasonable 109 ppi. But 2’ from screen seems reasonable to me for most of my work. Go closer to the screen and you will manage. At 109 ppi the angular divergence between adjacent pixels is 0.4 mrad so easily outperforming my ability to see pixelation - at that distance of course. When I work at the desk there’s roughly 2’ between my eyes and the screen. I recall learning a long time ago that our eye has an angular resolution of about down to 1 mrad (about 0.06 degrees). In terms of sharpness, I also think of it this way. I also like that my external screen renders at similar ppi as my internal. For comparison, my 14" MBP is native 1800x1169 (153 ppi) and I also run it at that resolution just because I want to see as much as possible despite the smaller screen size. ![]() This 4K is 163 ppi native, the way I am using it, however, is only 109 ppi, while the perfectly sharp downsample to 2K would be 86 ppi. But in reality, this choice is plenty sharp to my eye while I also get to see more content. Now, in principle that isn’t a subharmonic (1920x1080 would be) so you’d expect things not to be perfectly sharp. My 4K monitors are physically 3840x2160, but I have usually chosen to display content as 2560x1440 (hover mouse over chosen resolution to display exact specs). In the Displays section of System Settings you get to choose what resolution you want content displayed as. You don’t strictly need a 5K monitor with a 27" on a Mac any more than on a PC.Īt work I have several 27" Dell U2720Q that are 4K. ![]()
