I finally got my RX580 and just wanted to report back about HiDPI with it. But it’s also possible that Mojave is interfereing. I think you should be able to get the hidpi resolutions you want without black sidebars, bass on everything you’ve said. So you have to do those two things then you should in theory be able to setup hiDpi resolutions to any size and shape you want, but I can’t say more until I get my own rx580 to try it all out myself. There is a command line command to enable OS X to do that for you, or allegedly switchresx will do it for you. The other half is making sure OS X is configured to give you all those 200% hidpi resolutions based on the super big scaled resolutions defined in switchresx. There is an actual type of resolution setting in switchresx called “scaled”, and when you create those youbare halfway to having the hidpi setup you want. I’m fact when you see that 2560x1440 hiDPI, that is because somewhere in switchresx you have 5120x2880 defined as a “scaled” resolution. It depends on what your video card supports. Switchresx definitely can create those scaled resolutions of just about any size you want, I thought you were already doing that.

When it detects you have a compatible monitor it enables the different control panel GUI. So there is nothing special about retina displays they are just high resolution displays and Apple keeps a list of which monitor model numbers meet their criteria as being a Retina display.

Check out earlier posts where there are some links to articles for how to enable that via the command line and maybe you can get it turned back on somehow. The other thing is that when you upgraded to Mojave you might have turned off the mode for enabling the open ended hidpi stuff with non Apple branded retina monitors. Two things for you, when you create the larger resolution sizes you’re making them as “scaled” resolutions right? I assume so. The only way to get the equivalent of windows’ 125% and 150% modes is to fake OS X into thinking your display is bigger then it is and then using 200% of that, which the OS does.

If it’s not working then either you don’t have switchresx configured right or else Mojave is getting smarter about knowing what resolution your monitor actually is and only allowing 200% of that, which is dissappointing if so. If with the RX560 and SwitchResX you can fool OS X into thinking your monitor is 5k, then retina technology in OS X will magnify it at 200% down to 2560x1440 hiDPI. There is no way on OS X to specify 150% or 125%, for example and I assume it’s just always 200% of whatever resolution your monitor is or that OS X thinks your monitor’s resolution is. If you have a Retina display they hide all the details of what resolution the monitor actually is but they are using 200% magnification to create the higher fidelity, handled in the OS. The default retina mode is 200% magnification. On OS X, they do something similar but present it differently.

On windows you can say 125%, 150%, etc as how much of a Hidpi magnification to use and it’s all happening in the OS. That effectively puts windows in hidpi mode. On windows when you go into settings for the display, you choose a resolution and then you can choose a percentage for how to bump the size of fonts, windows, etc to be larger.


The OS is a huge part of the equation as well as compliance by application software.
