I'm not understanding 'profiles' in dt

Well, if you have received a device profile for your indivual monitor, using that should be fine.
If it’s a generic profile for your monitor type, it may or may not be good enough.

In both cases, checking that your monitor is calibrated is still a good start. For that, see your monitor documentation or the Benq website/vendor.

Having a good profile for your monitor has two advantages even in your case:

  • what the other parties see will be closer to what you intend for them to see, as you have removed the errors on one side.
  • and more important, perhaps, if you progress and decide to print some of your work, you’ll have less trouble getting the print colours close to the screen colours (“close to”, as the media are very different).
