Space Monitor 27" not showing full resolution on MacOS

JUMP TO SOLUTION

Hi, I have the Space Monitor 27" SR75 connected to a MacBook Air 2013 using a belkin adapter (mini DP to HDMI), the mac has the following specs:

Processor: 1.7 GHz Dual-Core Intel Core i7

Memory: 8 GB 1600 MHz DDR3

Graphics: Intel HD Graphics 5000 1536 MB

The monitor is supposed to work at 2560x1440 but the maximum resolution I get on MacOS is 1080p, the strange thing is I tested the same monitor on the same computer using windows 10 via bootcamp and the monitor works perfectly.

I've already tried resetting SMC and PRAM, using a different adapter with 4k support, restarting on safe mode, etc.

All of this make me think that it may be a firmware problem? Because as I said it works perfectly on the same computer on bootcamp.

After trying two HDMI to mini-displayport adapters I ended up buying a new mini-displayport to mini-displayport cable (without having to use adapters) and that fixed the problem.

And how would I do that? I called customer service yesterday and filed a report for missing macOS firmware and drivers.

MacOS has a limited number of display resolutions available depending on model.

Here is one link on changing that resolution:

Google changing Mac resolutions for more links and info.

 

As you said, the monitor works fine in Win 10 so don't blame the monitor for a lacking OS's limitations.

Already tried that, the problem is that its not showing the native resolution for the monitor.
I also checked if the macbook air model I'm using supported that resolution and the technical specifications say it does:

Graphics and Video Support

  • Intel HD Graphics 5000
  • Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on an external display, both at millions of colors

That is the Mac's problem, complain  to Apple.
