A good monitor is expensive. But its impact will be lost if you don"t take the pain to carefully (and intermittently) calibrate your monitor. The colors on the screen may not be the exact match of what they actually are.
To open the Display Color Calibration tool, press Windows + S or open the Start menu, search for "calibrate display color," then open the matching result, and follow the on-screen instructions.
To manually open the ClearType Text Tuner, press Windows + S, search for "adjust ClearType text," then follow the on-screen instructions. On each of five screens, you"ll select the text samples that look best to you.
The site offers this simple one-page monitor calibration tool to adjust the brightness and contrast of your screen thanks to the gray scale tones. The idea is to tweak the monitor settings (or buttons) so that you can clearly distinguish the transition of tones from true black to true white. After calibration, the blacks should look black and without any hint of gray.
The instructions start off by telling you to dim the lights and hit F11 for viewing the gray scale chart in full-screen mode. Observe your monitor from your normal viewing distance.
The Lagom LCD Monitor Test Pages are a far more comprehensive set of tools than Photo Friday. The site includes a series of test patterns that start from checking contrast to checking for response times of your monitor. It is recommended to go through the tests in the order they are placed.
For a beginner, it might seem overwhelming. But, the test patterns come with helpful explanations. The developer also states that you can put the images on a USB drive and try them in the computer store when shopping for an LCD monitor. A 120 KB ZIP file download is included.
The Online Monitor Test website has a range of interactive tests to fix your screen colors. The menu appears when you move your mouse to the top. It starts off with a test that checks the brightness and contrast across the B/W tonal spectrum. It is similar to the test we covered on the Photo Friday website.
Next, the Color Range test checks if your monitor can smoothly produce color gradients. From the menu, you can pick different color charts. Look for “ghost images” or image trails in the Trailing test. Move the box across the screen and check if any trails are produced. The controls and options to change the color and shape of the box are placed at the bottom.
The Homogeneity test helps to pinpoint damaged pixels and faulty monitors with backlight bleeding. 1:1 Pixel mapping and testing for a blurring of Text are the last two tests on the lineup. While the former is not so much an issue with LCD computer monitors, the latter is worth a tryout if you feel that screen text is not crisp enough.
This single page screen calibration chart has few of the test images we have already covered in the earlier tools. Go through the color, gray scale, and gamma adjustments.
- For more accurate measurements, do both black/white and inverse white/black tests, and average the results. LCD GtG pixel transitions are often asymmetric.
If the screen abnormality is not present in the built-in self-test mode, see the Dell knowledge base article How to Troubleshoot Display or Video Issues on a Dell Monitor.
If the LCD built-in self-test (BIST) diagnostic test passed, the laptop LCD screen is working correctly. The display problem could be due to an outdated graphics driver or incorrect video settings. Follow the troubleshooting instructions in the Dell knowledge base article How to Troubleshoot Display or Video Issues on a Dell Laptop.
Visuals on a screen are created by displaying multiple still images in sequence. The faster these sequences pass by, the more convincing the illusion, making the video look smoother.
This is one of the easiest tests to run, and also one of the most accurate. Just open the site and let it work its magic. TestUFO will automatically sync with your browser and check the refresh rate of the monitor. The results are displayed in the middle of the screen.
It’s an improved version of an older tool called Vsync Tester (which might still be better for older devices). Its accuracy is unmatched, giving you the refresh rate in six decimal points, which is leagues ahead of the competition.
This tool is especially useful when comparing multiple displays, as most screens will show roughly the same values. The additional precision allows for a better comparison to be made.
5. Support one‑key lock reference waveform, current waveform lock will be displayed on the screen, the normal refreshed waveform will not be affected.
6. One‑key storage of waveform on screen, can be transmitted to the computer via USB waveform, which is convenient for viewing and analyzing problems.
