Monitor Test Images

After I bought a new computer and monitor, I finally bought a gizmo to calibrate the monitor, called Huey, by Pantone. You use it by temporarily attaching it to your monitor screen then running the calibration program. The program displays different colors and gray levels on the screen while the gizmo measures the color and intensity of the light emitted by the monitor (it works for LCD or CRT monitors). After you specify a few options, the software reprograms your computer's display adapter circuitry so the monitor displays accurate colors and intensities.

Of course, that's all well and good. How do you know if it worked properly? You need some other way of verifying the performance of your monitor. I searched online and found several monitor test images that you can display. Each image is large and complex, to give your monitor and display hardware a good workout. The images also contain objects of known color (like color charts, flesh tones, fruit, flowers, etc.) to help you judge how well your monitor is working.

I also constructed a couple of test images of my own. I created the images on my computer using Paint Shop Pro, setting all the colors and gray levels to the correct numeric values, so the images should be accurate.

You can click on any of the thumbnails below to view the monitor test image. The first two images are from my web site, the remaining images are links to sites on the internet. Note that some of the images are in ZIP format, so after downloading the file, you must unzip it to extract the image file.
