Eizo Monitor Test vs MonitorTest Pro
Eizo's free monitor test (available at eizo.be/monitor-test/) is a popular resource for checking display quality — and a respected one. Eizo makes some of the most colour-accurate monitors on the market, and their test tool reflects that heritage. MonitorTest Pro takes the same idea further: more tests, no download, and full compatibility with any monitor brand — not just Eizo panels.
| Feature | Eizo Test | MonitorTest Pro |
|---|---|---|
| Number of tests | 13 | 20+ |
| Download required | Yes (Windows app) | No — runs in your browser |
| Works on any monitor brand | Yes | Yes |
| Motion blur test | Yes | Yes (full screen) |
| Dead pixel test | Basic | Advanced (per-resolution patterns) |
| Refresh rate / Hz test | No | Yes |
| Free | Yes | Yes |
If you've used the Eizo monitor test before and want a quicker, browser-based check — or you're testing a non-Eizo display and want a tool built for any brand — MonitorTest Pro is a natural complement.
How to Test Your Monitor Like Eizo Does
Eizo's methodology is the industry-standard approach, and MonitorTest Pro follows the same principles:
- Solid colour screens — full-screen red, green, blue, white, black, and grey reveal dead pixels, colour casts, and backlight uniformity issues.
- Gradient and ramp tests — smooth gradients expose banding, gamma errors, and panel uniformity problems that solid colours can hide.
- Geometry and sharpness patterns — grid lines and text patterns confirm your display is rendering at native resolution without scaling artefacts.
- Motion patterns — moving bars and UFO-style test charts reveal ghosting, motion blur, and overdrive overshoot.
Run each pattern in fullscreen (press F) for the most accurate read, and view from a normal seating distance in a dimly lit room.
Which Tests Eizo Includes
Eizo's monitor test suite covers the core checks below. Each links to the equivalent — and in most cases more advanced — MonitorTest Pro tool:
- Dead pixel test — full-screen colour cycling to find dead and stuck sub-pixels
- Colour accuracy test — primaries, greyscale ramp, and skin tone evaluation
- Gamma test — verify your panel is rendering the standard 2.2 gamma curve
- Contrast test — black level depth and contrast ratio checks
- Brightness test — peak nits and uniformity across the panel
- Motion blur test — moving-bar clarity test at your monitor's refresh rate (also useful as an eizo motion blur checker alternative)
- Sharpness / pixel grid test — native resolution rendering and sub-pixel inspection
- Uniformity test — colour and brightness consistency across the screen
- Viewing angle test — off-axis colour and contrast shift
Why Use Our Alternative Instead
- No download. Eizo's test requires installing a Windows application. MonitorTest Pro runs entirely in your browser — on Windows, macOS, Linux, Chromebooks, and tablets.
- More tests. 20+ diagnostic tools versus 13, including refresh rate / Hz testing and dedicated ghosting and response-time checks that Eizo's suite doesn't offer.
- Faster to start. No installer, no admin permissions, no waiting — click a test and it's running in fullscreen within seconds.
- Built for every brand. While Eizo's test naturally showcases Eizo panels, MonitorTest Pro is brand-neutral — equally useful for Samsung, LG, Dell, ASUS, AOC, Alienware, Gigabyte, and HP displays.
Frequently Asked Questions
Is MonitorTest Pro a replacement for the Eizo monitor test?
Not a replacement — a complement. Eizo's test is well-built and free, and many users like having both on hand. MonitorTest Pro adds more test categories (refresh rate, ghosting, response time, calibration) and removes the need to install anything, which makes it convenient for a quick browser-based check on any device.
Do I need an Eizo monitor to use MonitorTest Pro?
No. MonitorTest Pro works on any monitor, laptop screen, or TV from any manufacturer — Eizo, Samsung, LG, Dell, ASUS, and more. The tests are display-technology agnostic.
Which is better for checking colour accuracy — Eizo's test or MonitorTest Pro?
Both use the same fundamental approach (solid colours, grey ramps, skin-tone patches) for visual inspection. Neither replaces a hardware colorimeter for objective Delta-E measurement. MonitorTest Pro's colour accuracy test adds an sRGB coverage reference and a panel-type comparison table that Eizo's tool doesn't include.
Does MonitorTest Pro check for the same things as Eizo's motion blur checker?
Yes — the motion blur test runs a full-screen moving pattern at your monitor's actual refresh rate, the same principle behind Eizo's motion blur checker, with the added benefit of testing at multiple speeds.
