Help!! please. I need to adjust the brightness of a monitor.?

Question

I have a somewhat old monitor dating back from 2001. The thing is that I need to adjust the brightness and contrast because my printed material doesnt look the same. I would like to know like the default adjustment, it doesnt have to be precise, just something around so I can have peace of mind.


The thing is that the buttons that adjust the light are 2 different ones.


1 of them is like a circle with lines poking out, somewhat like a sun design.

and the other one looks like half filled circle, like a half moon.

These 2 buttons have the ability to go up to 100% each, but I dont know what percentage to set them individually.


do you know what percentage I could put?

Answer 1

The sun symbol is brightness. the circle cut in half is contrast.

If you have a white block on a black background, then increasing the brightness will make everything brighter. The black will look like a dark gray and the white will be brighter. The contrast control will just effect the white block. the 'black' should stay where it is but the white block will get brighter as you increase the contrast, dimmer as you decrease it.


Default values usually are 50% brightness 100% contrast. However, these are a compromise for manufacturing thousands of units a day, I would recommend you adjust them to better values:

Bring up windows as normal, changing the resolution or refresh rate can effect brightness and contrast so use your normal settings.

Wait 20 minutes for the monitor to warm up fully.

You first need a large block of black, so open up Paint, make the image nice and big and flood fill it with black.
Now adjust the brightness up and down. As you adjust it down there should be a point where the screen goes from darker and darker grays to where it is actually black and the adjustment no longer makes it any darker. This is called the cut-off point and is the ideal point for the brightness setting.

Now put a small white block up on the black background. Adjust the contrast up and down until it is at a brightness you are comfortable with.

That is the ideal set up for a CRT. You will get the best brightness from the image that gives a very high contrast between black and white.
