I have an acer h243h.

It is too bright. With brightness now set to 15 in a dim or dark room my blacks still have a bright look. with an all black screen it glows pretty bright.

I have tried setting my brightness to 0 and it is still bright.


I have found my colors are all set to 75. If I drop them to say 50 the screen appears darker, but I don't think that has any effect on an all black screen in a dark room.


I am at a loss. If I play a dark game in a dark room the blacks are very light.

During the day they look fine.


Help.

turn down the contrast not the brightness

I dont understand. Everything I have read thus far says turn the brightness way down and then adjust the contrast to get the picture right. I also thought the brightness is what controls the backlight?

nope


I know its confusing because brightness is a contradictory name for what the setting does


brightness controls the black level


contrast controls the white level

This icon indicates the BRIGHTNESS control, more properly called BLACK LEVEL. It adds or subtracts an offset, or bias, into the red, green, and blue signals. This control should be adjusted so that black picture content displays as true black on your monitor. Misadjustment of this control is the most common problem of poor quality picture reproduction on computer monitors, video monitors, and television sets. Later in this document, I will explain how to set this control properly. The setting is somewhat dependent upon ambient light. Modern display equipment is sufficiently stable that frequent adjustment is unnecessary.

This icon indicates the CONTRAST control, preferably called PICTURE. It applies a scale factor (gain) to the red, green, and blue signals. It affects the luminance (proportional to intensity) that is reproduced for a full white input signal. Once BRIGHTNESS is set correctly, CONTRAST should be set for comfortable viewing brightness.

neither actually control the backlight, most monitors do not allow you to adjust the backlight level, most LCD TV's do and it will be called backlight in the picture options
