My computer "monitor" settings were changed for an art project. How do I reset them.?

Is there a keyboard command to reset %26quot;monitor%26quot; to original alignment, there is no button on my monitor itself to do this. This an older model monitor. Please note, everything looks concave! lolMy computer %26quot;monitor%26quot; settings were changed for an art project. How do I reset them.?Is this a tube-type monitor?
