Samsung offers built-in diagnostic tools to ensure that users can maintain the optimal performance of their devices. These tools are easily accessible and allow users to check the functionality of their phone’s hardware, such as the display and touch screen sensitivity. This is particularly useful for troubleshooting issues without needing external assistance.
1. Why Run Diagnostics?
Running a self-test or diagnostic helps you:
- Identify dead/stuck pixels
- Check brightness, contrast, and color accuracy
- Diagnose “No Signal” or input issues
- Rule out whether the problem is with the monitor or the connected device
2. Samsung Monitor Self-Test
Most Samsung monitors include a built-in Self-Test Mode.
Steps:
- Turn off your computer (or disconnect the video cable).
- Leave the monitor powered on.
- If the monitor is working correctly, you’ll see a floating Samsung logo or a test screen.
- ✅ If the logo appears → The monitor is fine; the issue may be with the PC or cable.
- ❌ If nothing appears → The monitor may be faulty.

Diagnostic Tests and Troubleshooting
Routine checks on your Samsung device can pinpoint common display and system problems. This guide walks through the different ways you can test key functions of your device.
Accessing Diagnostic Mode
To test your Samsung device, you’ll need to access the diagnostic mode. This can often be done by dialing #0# on the phone’s keypad. The screen will then display a menu allowing you to select various tests.
Display and Touch Screen Evaluation
The display test will check your screen colors and resolution. Look for any lines or dead pixels that show there’s a screen issue. The touch screen test assesses touch sensitivity. Run your fingers across the screen to ensure every part responds as it should.
