AndroidResAdapter

A tool to adjust Android device resolution and orientation via ADB — useful for adapting to external monitors or projectors.

Requirements

• Android device with Developer options and USB debugging enabled
• ADB installed on your computer
• For wireless usage: enable Wireless debugging in Developer options

Quick Start

1. Connect

Wireless (with pairing code):

adb pair <ip>:<pairing_port> <pairing_code>
adb connect <ip>:<connect_port>

USB:

adb devices

2. Set Resolution & Orientation

# Disable auto-rotation, lock to landscape
adb shell settings put system accelerometer_rotation 0
adb shell settings put system user_rotation 1

# Override resolution (e.g. 1920×1080)
adb shell wm size 1920x1080

# Optional: adjust density
adb shell wm density 360

3. Restore Defaults

adb shell wm size reset
adb shell settings put system accelerometer_rotation 1
adb shell settings put system user_rotation 0

Useful Commands

Command	Description
adb shell wm size	View current resolution
adb shell wm density	View current density
adb shell dumpsys display | grep -i orientation	View display orientation
adb shell wm size reset	Reset to physical resolution
adb shell wm density reset	Reset to physical density

Orientation Values

user_rotation	Orientation
0	Portrait
1	Landscape (90°)
2	Portrait upside down (180°)
3	Landscape reverse (270°)

Notes

• wm size creates an override — the physical display remains unchanged, the system scales output to match.
• The override persists until wm size reset or device reboot.
• Not all apps handle non-native resolutions gracefully; some may appear cropped or misaligned.
