The display brightness should be adequately set to match the perceptual brightness of the room.
In addition, there is also the overall brightness to consider, which is measured in candela per square metre (cd/m2) or ‘nits’-the terms are interchangeable here as they both use the same measurement.

Using Displa圜AL with an i1 Display Pro to calibrate a display to D65 at 80cd/m2 Colourimeters include X-Rite’s i1 Display Pro and ColourMunki and datacolor’s Spyder models. There’s no easy way around it-if you’re serious about having a colour managed workflow, you will need to calibrate and profile your display, typically using a device such as a colourimeter. It’s even more important if you plan to interwork with other creatives, companies and print houses. Regardless of what type of work you do-whether it’s image editing, graphic design or print design-colour management is important for a professional workflow to ensure that your editing decisions regarding colour and tone are based on some kind of standard and are consistent. With colour management in place, that red value would no longer just be sent straight to the screen: instead, it would be translated based on the display profile to ensure it looks correct according to the characteristics of the display.
However, there’s no guarantee that the display will represent this red value accurately, especially if it reproduces colours much greater than the gamut of sRGB which is the colour space our imaginary document is in. Without colour management, this value would be sent to the display as-is. Here’s a very basic example: imagine we have a red colour value in our document which is in the sRGB colour space, and in 8-bit precision (where you have 256 unique colour values) we’ll say this red value is 240.
