From my personal experience, I prefer to resize the emulator screen size to 0.5, instead of 0.75 ratio.
- Right click on your project, select "Run As" -> "Run Configurations"
- Select "Target" tab, enter "-scale 0.5" in the "Additional Emulator Command Line Options" textbox, this will scale the screen size to 0.5 ratio. Please refer to the screen as shown below.
Note: Eclipse IDE required you to scroll down your "Target" tab screen to see the "Additional Emulator Command Line Options" textbox.
- Click on "Run" button, the emulator screen size will be scaled down.
