PowerStrip by EnTech is a 3rd party utility that allowed for adjusting color and timing parameters for displays way back before GPU drivers had them, as well as multi-monitor back before that was well supported by Windows.
GPU drivers should still allow you to adjust many of those things today, provided you have connected an analog monitor. Other settings may be hidden and require registry editing, etc. But unless you describe exactly what you are wanting to adjust and what GPU + monitor you have, then nobody can really provide a satisfactory answer.
