IOS – HiDPI Mode not respected by iOS Simulator

In case anybody is still interested, this issue changed slightly with Xcode 4.2, and I posted an updated question here: https://stackoverflow.com/questions/7922308/xcode-4-2-error-0xc002-when-trying-to-use-a-jailbroken-iphone-3g-for-developmen

You can't. I've been an iOS software developer for two years and I haven't been able to find a way do this. I have tried to find solutions to this but came up with nothing. I'd love to be proven wrong, but I'm 99% certain there's no way to do this.

When my screen is too small I use 50% scale window, which is ought to be enough until I hook up my big monitor again at home.

EDIT: As of Xcode 9, you can resize it to any way you want from the corner of the simulator.
