android studio/eclipse emulator showing only part of screen

Question

Since the last upgrade of packages, the Android Studio/Eclipse emulator shows only a fraction of the screen.

How can I view the whole screen again?

To re-install Eclipse does not help.

Answer 1

Two different settings influence the display size of a virtual device. The actual hardware display size of the specific hardware being emulated (Nexus One, Nexus S, ...) and the scaling factor that the emulator applies when rendering that display onto your computer screen. Both are properties of the virtual android device, so reinstalling Eclipse will not change them, but you can edit them in the Android Virtual Device Manager or on launching your emulator.

If you run your emulator from the command line, the third paragraph of the command line help page describes how to change both settings.

If you run your emulator from Eclipse, you may want to look at the launch configuration that you use for debugging your application. At the very bottom you can give the scaling factor and other properties as additional command line arguments. Make sure this is not set.

If nothing worked until here, just create a new virtual device for your emulator from the Eclipse toolbar.
