Is this two displays for a desktop computer, or a laptop or notebook computer ?

What do you mean when you say "go dark often" ?

Do the displays both go completely black ?

Or - do they still display video but they get much dimmer than they should be.

(If you're ONLY getting a display that is too dark in a game, you can almost always adjust that in the settings for the game itself.)

All LCD, LED LCD, and Plasma displays have an "optimal" or "native" resolution.
What you see on the display will NOT look as good in ANY OTHER RESOLUTION as it does when you use the "optimal" or "native" resolution, the most noticable thing in common being the text on the screen will NOT be as clear as it is when you use the "optimal" or "native" resolution.. The lower the quality of your display, the worse other resolutions will look. E.g. other resolutions will look worse on an Acer model than on a Samsung, LG, or Sony model.

If you're using a LCD or a LED LCD display, or a Plasma display on a TV, but don't know what the "optimal" or "native" resolution is, tell us which make and model the display is.

In addition to that, only SOME of the other resolutions have the same aspect ratio as the "optimal" or "native" resolution - the ratio of the width to the height of the display, expressed in whole numbers - e.g. 16:9 for a widescreen display, or 1.777 (to 1) when you divide the first number in the resolution by the second number. If the aspect ratio of the other resolution is different, you will either have
- black areas where no video is displayed at the sides or top and bottom of the screen,
- or - the horizontal or vertical of the display will be streched or squeezed to fit the screen and be out of proportion to what it should be.

(For a game, you can almost always set the resolution you use for the game itself in the settings for the game itself, without having to change the resolution for everything else in Windows. )

If you choose a resolution other than the "optimal" or "native" resolution...

Turn on Clear Type in Windows XP or Vista or Windows 7 - makes type/fonts on LCD screens look clearer.

With LCD Screens you don't want to disable optimal screen resolution unless there is some overpowering reason for it and you can stand the loss of quality.

Screen going dark has nothing to do with resolution, more likely the LCD backlit is failing. Is this on both monitors or just the one.
