Dell 2001FP LCD monitor too bright!

Even with the OSD 'brightness' turned all the way down to zero, the
backlighting is too intense to give a deep black background to the screen I
prefer. I'm using the DVI inputs, so the 'contrast' control is disabled.

Are there internal adjustments to decrease the brightness of the backlight?

Is it possible to insert a sheet of translucent gray plastic (a poor man's
neutral-density filter) between the lamps and the LCD?

I'm reluctant to open up this costly toy just to see. :) Any sites with
diagrams showing the internal construction of LCD monitors?

Any other ideas, that wouldn't affect image quality?

Thanks,

Thomas

Without seeing the monitor, I would not be able to judge how black it is.
Someone who is used to servicing monitors, and are used to them, can tell
you right away if the monitor is normal or not.

All LCD displays do not go down to zero black. There will always be some
breakthrough. They are actually best in a slightly or moderately (not too
bright) lit room, rather than a very dark room.

We have 3 LCD monitors at our site, and they are all slightly lit when
totally black and powered up, when looked at in a normal room. This is one
of the faults of these monitors when used for precise photo finishing. This
effect will produce inaccuracies in the very dark grey's and black levels.

I guess I will have to learn to live with less-than-perfect blacks. Too
bad, other than that it's a wonderful monitor.
