Monitor Test
Eight test patterns in one place. Click a pattern, go full screen, and check your display in a few minutes.
How to Use the Monitor Test
This monitor test gives you the classic calibration patterns: gradients for banding, black and white levels, a gamma chart, a contrast ramp, sharpness lines and text, a uniformity screen and a viewing angle check. Use it after buying a new monitor or before you calibrate.
- Pick a pattern. Each one has a short tip above it.
- Go full screen. For the most honest result.
- Adjust your monitor. Use brightness, contrast and gamma in the monitor menu.
- Recheck. Go through every pattern once more.
What Each Pattern Checks
| Pattern | Checks | Good result |
|---|---|---|
| Gradient | Colour depth, banding | Smooth, no steps |
| Black level | Shadow detail | Squares from about 3–5 visible |
| White level | Highlight detail | Squares up to about 250 visible |
| Gamma | Mid-tone brightness | Blends at 2.2 |
| Contrast | Tone steps | All steps distinct |
| Sharpness | Text clarity | Crisp, no halos |
| Uniformity | Even backlight | No dark corners |
| Viewing angle | Colour shift | Little change off-axis |
Black Level Looks Wrong?
If the first 10–20 squares are invisible, your graphics card may be sending limited range (16–235) to a monitor that expects full range (0–255). Set the output dynamic range to Full in the NVIDIA, AMD or Intel control panel.
Do I Need a Calibrator?
For photo and video work, a hardware calibrator is best. For gaming and everyday use, these patterns get you most of the way.
Frequently Asked Questions
Can I calibrate my monitor with this?
You can get brightness, contrast and gamma close. Colour accuracy needs a hardware calibrator.
What gamma should I use?
2.2 for most screens and content.
Why do I see bands in the gradient?
Your panel or GPU uses fewer colours, or a colour profile is causing banding.
Does it work on TVs and phones?
Yes.
