Set display resolution and scale factor

When this policy is set, resolution and scale factor of each
display are set to the specified values. External display settings are
applied to all connected external displays.

Values of "external_width" and "external_height" should be specified in
pixels. Values of "external_scale_percentage" and
"internal_scale_percentage" should be specified in percents.

If "external_use_native" is set to true, policy will ignore values of
"external_height" and "external_width" and set resolution of the external
displays to their native resolution.

If "external_use_native" is false or not provided and either
"external_height" or "external_width" is not provided, policy doesn't
affect the external display settings. If specified resolution or
scale factor is not supported by some display, policy is not applied to
that display.

If "recommended" flag is set to true, users may change resolution and
scale factor of any display via the settings page after logging in, but
their settings will be overriden by the policy value at the next reboot.
If "recommended" flag is set to false or not set, users can't change the
display settings.
See https://cloud.google.com/docs/chrome-enterprise/policies/?policy=DeviceDisplayResolution for more information about schema and formatting.

Example value:

{
"external_width": 1920,
"external_height": 1080,
"recommended": true,
"external_scale_percentage": 100,
"internal_scale_percentage": 150,
"external_use_native": false
}
