If you're a Windows user, you may not know that you have a built-in calibrating tool you can use to ensure colours are represented accurately on your monitor. The tool is titled 'Display Color Calibration' and can be found by clicking the 'Start' button and selecting 'Control Panel'. When a new window opens showing the Control Panel options use the search box to find the tool by typing 'calibrate display' then click on 'Calibrate display color'.
Even though this tool is built-in, if you own a display calibration device that came with other software, it's always best to use this rather than the built-in option as you'll be able to achieve more accurate results. Using an instrument to measure / calibrate your monitor will result in a better calibration than when carried out visually.
When you've clicked 'Calibrate display color' the above window will open.
From here, you need to click 'Next' to continue with the process. Various colour settings will be able to be adjusted but what exactly can be changed and how will depend on the display you are using. Before you make adjustments, an instruction page will explain the process for each of the changes you'll be making.
Gamma adjustments will be the first option that will appear. To set the correct Gamma, you have to move a slider (which can be found on the page after the one you're currently on) to minimise the visibility of the small dots present in the middle of each circle so the sample image looks like the square labeled 'Good gamma'.
Next comes brightness and contrast which can be adjusted via your monitor's display menu or by using brightness / contrast buttons on the front of the display. If your monitor doesn't have these options you can skip this step.
As before, three sample images are shown so when adjusting the brightness, you'll know that you want the sample image to look like the photo labeled 'Good brightness'.
The same applies for adjusting the contrast settings. You want the sample image to look like the 'Good contrast' photo once the adjustment is applied.
The final adjustment is colour balance which determines how grey shades appear on your display. After the instruction page you'll be shown a series of greys which have red, green and blue sliders under them and you need to use the sliders to remove any colour cast you see in the grey shades.
Once complete, you can compare the calibration results with the previous one, if you like, or you can just click 'Finish' to save the new target.
