Being a browser test and depending on the equipment, it may not sync properly and continually give us the error “browser stutter detected“, in this case, we have to stop moving even the mouse or just change the browser.
In all our teams it worked much better firefox than Chrome, so we recommend the former, as it goes up to 240hz synchronization. Of the three large sections that the web has in its menu, we will focus on explaining the 7 tests that include it, since they are designed precisely to test each monitor.
That said, let’s start with the best monitor tests, how good do you think yours will be?
Ghost
This test is very useful, since we can check if our monitor suffers from the dreaded ghosting, overdrive or coronas. The most recommended configuration will go through a speed equal to the vertical pixels of your monitor (in our case 1440P for him PG348Q) and a black/grey/white background for its contrast and to blend in with the web wallpaper.
How will we notice ghosting? Simply if the UFO image, in one of three versions leave a trace. The larger the wake of the drawing itself, the greater the ghosting and the worse the feeling of fluidity we will have. A very pronounced ghosting would be something like the video we see just above.
Logically, the higher the speed in terms of refresh rate, the more ghosting we will have and the more appreciable the effect will be in the test, so monitors that exceed 60 Hz will see the effect amplified if they suffer from it. Others, on the other hand, if they are really competitive, should not.
Blurred Trail / PWM
In this test, we are looking possible artifacts on vertical lines, default white. The process to know if the screen update time is correct is very simple: just follow each vertical line with your eyes. If it stays in its shape and there are no tears or deformations, this will indicate that everything is correct.
If you find it difficult to follow the lines and enjoy them, you can increase the pixels per frame, which will increase their speed and make it easier for us to detect.
Moving picture
This test creates a movement using a loop repeated photography, simulating Windows window scrolling or instantaneous movements in FPS video games. What we are looking for is sharpness of pictures when it moves, for this reason we again recommend setting the speed to the vertical pixels of your monitor.
The less sharpness you get, the worse. It’s a pretty demanding test for some panel types, especially IPS and VA, where TNs tend to move better due to the way their pixels change color. The higher the pixel speed we have, normally it should be set in the vertical resolution of our monitor (eg in FHD it’s 1080p, 2K it’s 1440p and 4K it’s 2160p) for the test to have makes more sense and whether or not the monitor exhibits whatever issues it may have.
hunting squares
Another very simple but effective test. What we are looking for is precisely what we see in the image above, let the two rectangles touch
To do this, we go back to select the speed corresponding to the vertical in pixels of our monitor and we will have to go lower or increase the distance in pixels between the rectangles. Less distance equals a better screen because you’ll have less blur and less ghosting. Logically, the best value is zero, since they would be together, but as we increase the speed it becomes harder to keep up with them and the impression of the distance changes, so it also admits negative values.
It is a test that it is recommended to pass in full screen because it is difficult to see if with a value 0 the rectangles touch each other perfectly or overlap.
Moving Picture Response Time (MPRT)
This test is a bit complicated, mainly because we will have to adjust the checkerboard size y el thickness until we get a chessboard like the one seen in the image above, where black and white squares must be the same size. The ideal would be, for example, to fix 6 pixels by 6 pixels, since that gives a perfect square, but all the monitors do not allow a clear image without distortions where the UFO moves freely.
What we are looking for is that said chessboard does not move or move forward, at least as little as possible, so that the UFO slides along it while the bottom remains staticand so we will be able to know the MCR and the MPRT of our monitor.
Pixels per frame is the jarring value, normally 12 is fine for the square background to be static, but will need to be manually adjusted up or down.
Inversion artifacts
So-called inversion artifacts are one of the toughest tests for any monitor, because may distort colors or color gamut within the same pattern. We’ll just have to try each setting to see how it behaves moving.
What we are looking for is not to place the images vertically, but to check how, when the top one moves, their color or shape is distorted. More speed without distortion is better.
Logically, we will have to follow the bars with our eyes, so be careful that it makes you dizzy.
Aliasing Visibility
In this case, we are looking for the visibility of the Aliasingwhere the test is once again very simple, you have to put the test in full screen mode and gradually move away from the monitor until we no longer distinguish any Aliasing. We can switch between different colors and pixel thicknesses to check the level accepted by our monitor.
Monitors with higher pixel density or higher resolution will find the aliasing harder to see, those with lower resolutions and low density will immediately appreciate it. So you have to play with the settings to see where the limit of the panel is.
And so far the best tests for your monitors, how is your screen? Does it meet your expectations?
