How good is your monitor, really? Even without professional equipment, you can get a fairly decent idea of your monitor's quality by performing some quick tests with free, browser-based tools and games.Add How-To Geek on Google Add as Preferred Source Follow on Google Discover Bear in mind that the quality of your eyesight can sway the efficacy of some of these tools.You'll have trouble getting objective results from a color accuracy test if you're colorblind, for example.
You should let your monitor or screen warm up for at least half an hour before performing these tests.Because they're all browser-based, you should repeat tests in more than one browser.Clean your screen if it's smeared or dirty, as oils and dust can make it difficult to interpret monitor performance.
ScreenTester.io A great option if you have no idea what you're doing Close Intimidated by the classic testing tools? ScreenTester.io gathers a ton of tests into one website with super-clear instructions.Pick from the tabs at the top of the website, which include tests for color calibration, dead pixels, refresh rate, and more, then scroll down for a guide on how to use the test and improve your setup.ScreenTester.io is also notable for its inclusion of some uncommon testing tools, like a touch screen tester, which is especially useful if you think that your device's multi-touch or stylus capabilities are damaged in some way.
TESTUFO The classic motion test TESTUFO has been the industry-standard tool for observing and demonstrating monitor motion quality for as long as I can remember.You've probably seen it in YouTube videos even if you've never tried it yourself, and anecdotally speaking, I always know that I'm about to be impressed when monitor brands are confident enough to pull up TESTUFO at trade shows.There are two main TESTUFO tools.
The first is the refresh rate test, which is good for verifying whether your operating system is working at the refresh rate it tells you it's using (though it specifically tests your browser, not your system or your monitor).Then there's the classic ghosting test, which uses a trio of UFO animations to make motion blur, ghosting, and other artifacts easy to observe on your display.Plus, TESTUFO offers other great tools, like a frame skipping test (which requires a camera), and a browser animation timing test.
Bear in mind that you should run all of TESTUFO's tools in full-screen mode.Just click the animated tool to go full-screen.Some tools also let you click and drag to observe how vertical motion looks on your display.
Blur Busters, the team behind TESTUFO, has some excellent articles on its websiteexplaining the different effects you might notice while testing a monitor for motion clarity and refresh rate.Related Windows 11 looks and runs better when you disable this feature I was a big fan of Windows Aero, but I recently disabled transparency effects on my Windows PC and I'm not going back.Posts 8 By Goran Damnjanovic EIZO Monitor Test A guided suite of monitor-testing tools If you want to test all aspects of your monitor in one go, EIZO Monitor Test is a super-convienent option.
It guides you step-by-step through a series of up to 13 tests which primarily focus on visual quality—viewing angles, sharpness, uniformity, defective pixels, and so on.That said, it ends with a response time test that's surprisingly easy on the eyes.All of the EIZO tests include on-screen instructions so you can correctly interpret what you're observing.
Some tests also provide sliders or settings so that you can modify testing parameters.To navigate through the EIZO Monitor Test, simply use the scroll wheel on your mouse, the up and down arrows on your keyboard, or the on-screen navigation panel.Your ΔE(OK) JND? I'm not sure how to pronounce it either Testing a monitor's color reproduction can be a humbling experience.
Sometimes you think that you've dialed in your color calibration perfectly, only to realize that you made everything worse.Other times, you realize that the monitor you've spent months or years getting used to actually looks kind of terrible.In any case, it's a worthwhile way to spend some time.
And a game called 'What's My ΔEOK JND?,' which launched earlier this year, is still one of my favorite ways to check a monitor's color accuracy.The game is simple: two colors appear on screen, click the border between the colors, and try to ignore the game's taunts.It's as much a monitor test as it is an eye test.
The goal is to get as low a score as possible.A score of roughly 0.005 seems to be relatively common for people testing on high-quality screens, but again, eyesight is also a factor here.I suggest testing 'What's My ΔEOK JND?' on the highest-quality screen that you own before using it on lower-quality displays.
That way you can have a decent point of reference beyond your fleshy little eyeballs.A colorimeter will provide more objective results.Related Please stop using your high refresh rate monitor on default settings Even a 240Hz monitor looks like a watercolor painting if it's not set up correctly.
Posts 5 By Ismar Hrnjicevic These tools work on mobile, too All of these tools work on smartphones and tablets, you just need to open them in your browser of choice.In fact, if you've got a flagship phone with a high-quality screen, I suggest that you use it to run motion blur and color tests so you have a good frame of reference before moving to desktop.Just keep in mind that auto-brightness can sway results mid-test.
Your phone's battery-saving features (which may kick on when your battery is low, even if you don't enable Battery Saver manually) can also impact screen refresh rate, and if you've ever modified your phone's color settings, you may find that color tests are less accurate than they should be.Turn off eye comfort settings before performing tests on mobile as well.
