Just bought an Acer CB280HK monitor and I display port to mini displayport 1.2 cable. At the native 3840x2160, the text is just a bit too small. I've upgraded Yosemite today to 10.10.3 under the resolution in display prefs all the options I get are as follows :

Native 3840x2160
1600x900
1080p
720p

The screen in only running at 30hz but it is capable of 60hz. I'm ensuring that DP 1.2 is switched on in the monitor onscreen menu. I have selected to scale the display for larger text but it is still way too small to be usable.

Reading up about Mac OS X, with the latest update their should be more resolution options, but I'm not seeing them.

Any ideas ?

thanks for the link, I've given that program a try but still not getting great results, I was kinda hoping I could even get 1920x1200 but that res isn't on the list. If I have the native 3840x2160 selected and use the accessibility options to zoom in one or two stops, the text and screen size is perfect, however the only problem with zoom is that you have to move about at the screen edges to see the menus etc and this is very annoying.

Was hoping for better with this monitor. I don't understand why OS X doesn't provide more resolutions lower than the native ? I am not too bothered about 60hz, 30hz is fine for what I do, but just can't read the text.

- 1920x1200 (16:10) would be a strange option for your monitor (16:9) and would result in distorted images, because it would have to stretch UI elements vertically.

Basically, anything other than native or 1920x1080 in HiDPI mode won't look good.

What resolutions do you feel you're missing?

- According to your initial post, that resolution ("1080p") is available directly in System Preferences.

yeah managed to get 1080p it looks awful compared to 4k obviously but at least it is readable, everything is just a bit big, thought there might be something in between 1080 and 4k?

Been reading that in OS X Yosemite the system font is much smaller than previous OS releases. Can't understand why you can adjust system font scaling as in windows.

- Isn't it running in HiDPI mode at that resolution? If so that should look really good and give a Retina like appearance. Regular 1920 x 1080 would look terrible, indeed.
Don't you have a "1920 x 1080 (HiDPI)" in System Preferences (like below)?

Unfortunatly I don't have any of those resolution options, none are HIDPI. Any how I can get these ?

My System is a Mid 2014 Retina MBP 13" with Iris Gfx. I am using a 1.2 compliant startech Display Port to Mini Display Port cable. Haven't tried HDMI yet.

- They're just sort of there for me. I haven't done anything to get them.
So if they don't show up in your System Preferences, and if SwitchResX doesn't help you, either, then I'm afraid I don't know...
