Re: How to get the best colours on your LCD monitorBefore you begin, make sure your display has been on for at least a half-hour (so it's properly warmed up) and are set to its native screen resolution. Even if you use it at a different resolution (and we can't imagine why), set it back to its native resolution while you calibrate it. Then, make sure you know your way around the controls for your display. This shouldn't be difficult to do—just take a look at the front of the panel. You'll likely see buttons near the power button to do things like switch inputs and open and navigate the on-screen options menu. These menus vary across display manufacturers, so there's no one way to open these menus and navigate them, but you want to find your color, contrast, and brightness controls. Once you find them, you're ready to get started. I hope this will help.
Re: How to get the best colours on your LCD monitorWhile you are working on these settings, you can also consider (if using Windows 10) to set up your night light settings. These settings will dim the blue light during a specific time of day, which is really nice and easy on the eyes.
