First thing first,

Using Android Studio 2.3.3

Problem:

My emulator screen is covering the only partial amount o

Answer 1

I was having the same problem too. I think it started happening when I updated to Android Studio 3.0 Beta 1, but I'm not 100% sure of that.

FIX: Anyway, to fix this, you can use Software Graphics in the emulator options, rather than Hardware. Slower, but at least it works.

Answer 2

I have this similar issue. It happened after using an external monitor that has lower resolution (1440 x 900) than my laptop (2160 x 1440) has. There are couple of ways you can fix it until Google fix the issue.

• if you match your PC's resolution to your external monitor's resolution. Then you can return back to your PC's resolution.
• If you lower the scaling of your PC ( mine was 150% > 125% or 100%) from Display Settings. Run the emulator. Again, you can return back to your original scaling, emulator screen won't change. This is the one I prefer.

Note: this is not a permanent solution. You may need to change scaling/resolution again if you change your scaling or resolution to the one you had issue with. I have tested this only on Windows 10 Pro, but this approach might work on Mac as well.

Answer 3

Try this and hopefully it works for you -

1. Go to Tools in Android Studio and open AVD Manager

2. It will open all your virtual devices. Click on the Virtual device you want to edit and click the Pencil icon which will enable you to edit the device.

3. Click on Change where it lists the device name. For example, for me my device name is Nexus 5X and lists the resolution of the device.

4. In the Select a Device screen, click on New Hardware Profile and change the resolution to 1080 x 1920 px.

5. Save the changes and run it again. If it still doesn't work, change the skin of the device.
6. If still doesn't work, then make a new hardware profile with a new device.

Answer 4

Best and simplest way to do it on Windows 10:

1. Close your Android Emulator if it is open
2. Right-click desktop
3. Click Display Settings
4. Set Scale and layout to 100%
5. Open Android Emulator
6. Revert your Scale and layout to the (Recommended) percentage

Answer 5

Open the Emulator and press Ctrl+Up_Key to increase the scale and Ctrl+Down_Key to scale down. (Cmd+KUp / Cmd+KDown if you are on mac)

Answer 6

Just go to display setting and change it to 100%.this normally happens if you have a fourteen inch laptop and below
