This is somewhat more real-world than on/off readings because it tests a display’s ability to simultaneously maintain low black and full white levels, factoring in screen uniformity. To perform this test, a checkerboard pattern of 16, 0 and 100% squares is measured. Click on the Calibrate display color option to proceed. Open the Start menu and type calibrate display in the search bar.

Calibrated contrast should be as close as possible to uncalibrated contrastĪnother important gauge of contrast is ANSI. Here’s how you can calibrate a monitor or display on Windows 10.

A few monitors are color-accurate without adjustment and, therefore, best left uncalibrated to maximize contrast. If we measure a significant difference, we weigh the reduction against the improvement in color accuracy. If a monitor’s contrast is consistent, it makes little to no difference on the calibrated black level and contrast measurements.Ĭalibration often reduces contrast slightly. In a dark room, many professionals prefer a 120 cd/m 2 calibration. On some monitors, 200 nits also the sweet spot for gamma and grayscale tracking. Follow the On-Screen Instructions: The wizard will guide you through adjusting gamma, brightness, contrast, and color balance.

The Windows Color Calibration Wizard will open. In a room with some ambient light, like an office, this brightness level provides a sharp, punchy image with maximum detail and minimal eye fatigue. Run the Windows Color Calibration Wizard: Click on Calibrate display or Calibrate color. Navigate to Display devices and expand it. Right-click the Start button and select Device Manager.

Please see the Display driver troubleshooting below: Option 1: Try Rolling back the Display driver. Since we consider 200 cd/m 2 to be an ideal point for peak output, we calibrate all of our test monitors to that value. Brightness is controlled by the display driver. Contrast ratio should remain the same regardless of the backlight setting.The minimum white level should be at or close to 50 cd/m 2.In those cases, we suggest a minimum setting for the brightness control that results in 50 cd/m 2 output. Some monitors become too dark for practical use. The purpose of this test is to see if the monitor’s contrast ratio remains constant throughout the entire luminance range. Anything under that results in a dim picture that can cause eye fatigue even in a completely dark room. We believe 50 cd/m 2 is a practical lower limit. There really isn’t a better or worse result here. Better displays will exceed 1,000:1 contrastįor the minimum brightness tests, we turn the backlight to its lowest setting and measure the white and black field patterns again.Monitor should meet or exceed manufacturer's stated maximum brightness value.Patterns used: Full White Field, Full Black Field.And again, we recommend leaving the ASCR dynamic contrast setting off as well. Unless you want to improve off-axis image quality, leave the Smart View option off. There is no gamma setting in any mode, but that didn't have a negative effect on our test results. And you still have access to the RGB controls. In Standard mode, however, you can run Contrast up to 80 without penalty. In fact, you have to turn it down to 35 to correct this, making the image look flat and dull. But the Contrast control, at its default setting of 80, clips information at the bright end of the scale. And transparency fades the menu out so you can see the image behind.Īt first glance, Theater mode seems to be the best choice for calibration, since it unlocks all image adjustments. DDC/CI should be left on if you want to allow your computer to have two-way communication with the VG248QE.

It’s always nice to be able to get the menu off the center of the screen and away from test patterns. The first three controls position the OSD and set its timeout value.
