I have a dell crt monitor. Luminance Temperatura pop up on the screen and it go on and off. Sometimes contrast or bright appear on bottom of the luminance temperature. How do I fix?

The second button from the left on the bottom corner by the power button is the brightness button. If you press it the brightness menu is pop up on the screen. With the menu up you just use the three buttons on the left to select the function and the increase or decrease the brightness and contrast on the monitor.

You can adjust luminance directly of monitor menu

dell website ,,support options,,also check menu ,,and control panel on cpu make sure its set for rght htz settings

how old is your monitor? sometimes its not in the menu button the problems exist. If your a pro, you can remove the casing of your monitor, check if there some bad capacitor on the main board, replace the bad parts.

I do not have a credit card for answer of this question...but I have the luminance t. problem? what do I do now?

The up/down button on your flat panel is stuck. Please contact Dell Technical Support to have the monitor replaced if its still within warranty.
