Screen Test

Check your dead pixels / benchmark your GPU performance with a detailed score!

Quickly identify dead pixels and test your graphics card's speed with captivating particle effects! You'll receive a score upon completion. For best results, close other apps, use fullscreen mode, and wait patiently for your score. Use this online tool to compare device performance before you buy.

Hot keys: ESC - Exit fullscreen mode; F - Resume fullscreen mode.

How does the screen test work and what do I need to do?

The screen test has two main parts to evaluate your monitor and graphics card.

Part 1: Monitor Color Test (7 Steps): We'll display seven solid colors (red, green, blue, black, white, yellow, and magenta) one at a time. To move to the next color, simply click your mouse or press the ENTER or SPACEBAR key. This helps you check for dead pixels and assess your monitor's color accuracy.
Part 2: GPU Stress Test (10 Steps): This part is automatic. We'll show you ten increasingly complex particle animations. Your graphics card will be working hard to render these smoothly.

To complete the test: Just follow the on-screen instructions. After the animations, click your mouse one last time to see your results. You'll get a score based on how well your hardware handled the test.

How can I ensure I get an accurate score on the screen test?

To get the most accurate results, we recommend the following:

Fullscreen Mode: Run the test in fullscreen mode. This helps prevent interference from other windows or applications.
Close Other Applications: Close any unnecessary programs and browser tabs. This frees up resources for your graphics card to focus on the test.
Don't Interrupt the Test: Let the test run to completion without minimizing or switching windows. If the test is interrupted or you experience any issues, simply restart it for accurate results.
Wait for the Particle Effects to Finish: The test automatically adjusts the number of particles to find the best performance of your system. Please wait patiently for the particle animations to complete.

By following these tips, you'll help ensure the test accurately reflects your hardware's performance.

How is my score calculated?

Your final score is calculated using three components that measure different aspects of your system's performance:

Base Score
This represents your system's raw particle handling capability.
Base Score = Average Stable Particles ÷ 100
For example, if your system can handle an average of 120,000 particles, your base score would be 1,200.
Consistency Bonus
This rewards systems that maintain stable performance across different effects.
Variance = Standard deviation of particle counts squared
Consistency Score = 1 - min(1, variance ÷ (average_particles²))
Maximum Bonus = Base Score × 0.2
Consistency Bonus = Maximum Bonus × Consistency Score
Example:
- Base Score: 1,200
- Maximum possible bonus: 240 (20% of 1,200)
- If Consistency Score is 90%, you get 216 bonus points
Resolution Bonus
This accounts for the additional processing required for larger displays. It has a maximum limit of 15% the Base Score.
Base Resolution = 1048 × 768 = 804,864 pixels
Your Resolution = width × height pixels
Resolution Factor = Your Resolution ÷ Base Resolution
Resolution Bonus = (min(1.5, Resolution Factor) × Base Score) / 10
Example for a 2K display (2560×1440):
- Your Resolution = 3,686,400 pixels
- Resolution Factor = min(1.5, 3,686,400 ÷ 804,864) / 10 = 0.15
- If Base Score is 1,200, Resolution Bonus = 1,200 * 0.15 = 180

Final Score = Base Score + Consistency Bonus + Resolution Bonus

Complete Example:
- Base Score: 800
- Consistency Bonus: 144 (90% consistency)
- Resolution Bonus: 5,496 (2K display)
- Final Score: 800 + 144 + 120 = 1,064

Note: The test runs multiple particle effects to ensure a comprehensive evaluation of your system's graphics capabilities. Each effect tests different aspects of rendering performance.
