Want to get monitor out of default mode .how do I do this ?

Hi,

Can you give a little more detail of exactly when or running into this?

Is it in display settings?

Did it work previously or a new problem?

Any hardware add-on devices that you think might be related to the problem you're seeing.

Any changes that either happened or that you perhaps made to your computer around the time that the problem started; particularly any Software or Hardware that you installed or setup.

What OS?
