I have a 4K monitor and some icons are blurry, and/or some parts of the UI are out of screen (Genymotion Desktop)

Overview

Since Genymotion Desktop 3.8.0, Genymotion support auto-scaling.

Auto-scaling makes it possible to use Genymotion on 4k monitors without further tweaking.

Auto-scaling may cause icons to appear blurry.

Some parts of the interface may be out of screen on some 4k monitor resolutions.

To fix this, auto-scaling can be disabled and customized.

In order to do so, you can set the following variables.

• QT_AUTO_SCREEN_SCALE_FACTOR=0 disables auto-scaling.
• QT_SCALE_FACTOR=[value] customizes scaling.

Windows

• Press Windows + R to open the Windows Run prompt.
• Type in sysdm.cpl and click OK.
• Click the Environment Variables button under the Advanced tab.
• You can either create a User Variable or a System Variable.

User variable

• To create a user variable, click New under the User Variables section.

System variable

• To create a system variable, click New under the System Variables section.

• Type "QT_AUTO_SCREEN_SCALE_FACTOR" in "Variable Name" field.
• In the "Variable value" field, type "0" to disable auto-scaling. Click "OK" to confirm.
• Create another new variable.
• Now, type "QT_SCALE_FACTOR" in "Variable Name" field.
• Next, in the "Variable Value" field, insert a number to increase (>1) or decrease (<1) the scaling factor. For exemple "0.75" will decrease scaling of text and icons by 0.75.
• In the main window, click "Apply" and "Ok" buttons.
• Restart Windows to apply the new environment variable.

Linux/macOS

• You can either start Genymotion from a terminal with the variables:

  QT_AUTO_SCREEN_SCALE_FACTOR=0 QT_SCALE_FACTOR=0.75 ./genymotion
  

• Or export the variable temporarily and start Genymotion from a terminal

  $ export QT_AUTO_SCREEN_SCALE_FACTOR=0
  $ export QT_SCALE_FACTOR=0.75
  $ ./genymotion
  

• Or add the variables to your .bashrc (Linux) or ~/.bash-profile (macOS) file, to set it permanently.
• In this example, we have set a value of "0.75" to decrease scaling of text and icons by 0.75, but you can use any other value to change scaling to your liking (>1 to increase scaling, <1 to decrease it).
