Do crt monitors need driver updates? Now seeing the difference between my 2 monitors, this tells me that everyone sees, images differently. Obviously I have been viewing wallpapers, windowblinds, etc. darker than others. Is this the norm, or am I doing something wrong?
Both CRTs and LCDs come with 'drivers' and colour profiles. The 'drivers' tell the video card about any features you particular monitors has and the colour profile specifies the colour response of the monitor to allow you to standardize the colours of you images. You can of course use your display(s) without them as Windows supplies 'generic' versions of these files.
CRTs darken over time. The phosphors on the crt have a half life. The half life is the point at which the 'brightness' of the phosphor is half as intense as when is was new.
So you are not doing anything 'wrong' per se.
