iOS Simulator display scaled incorrectly

Question

I came back to X-code after a few months break. In that time in which x-code wasn't used it was kept updated however.

Now when I Launch the iOS simulator the display is scaled wrong. I have worked at home with an external monitor 1920x1080 and the simulator runs correctly. However when I run the simulator on my Retina display it looks like the image below.

Ive tried resetting the simulator and settings, uninstalling and reinstalling x-code. and several other things but the display is still scaled for a 1920x1080 screen and I don't know how to change that so that its for a Retina display again.

Any Ideas?

Sometimes things that change your display profile fail to change it back, i.e. flux or screenresx. Your resolution may appear to be the same but it isnt. I only noticed bc the font rendering seemed ever so slightly fuzzier. Go to System Settings > Displays and re-select your desired resolution. This is probably not the answer in most cases, but it helped me this time.

I have the temporary fix for this OS X bug.

I have this bug at work but not at home, so I thought it's a toggle problem, depending maybe on different internet connections (so stupid decision, anyway) :)

In Apple forum someone mentioned "external monitor", and at that moment I said myself EUREKA, we have a fix, but temporary for this bug:

Another way to fix this issue (temporally) is by having the simulator being opened in Low Resolution.

How to open the simulator in low resolution:

• Open the simulator from within Xcode
• Right click the simulator in the dock and choose Options > Show in Finder
• Right click the simulator in Finder and choose Get Info
• Check Open in Low Resolution
• Close the simulator
• Reopen the simulator from within Xcode

This is a known bug in OS X 10.10.2 beta.
