LG LCD monitor - can't get anything close to black on display.

I bought an LG L1715S monitor recently because my CRT was making my head
hurt after a while (even at 85Hz) and it had become quite blurry.

Anyway, the display is nice and crisp, but the intensity range is
just... wrong. And I don't know whether this is the result of buying a
low-end TFT or whether there's something wrong with the display unit.

Basically, black (a screen filled with 0,0,0 in, say, Microsoft Paint)
appears as a kind of grey purple. Even with the Brightness at 0 and
contrast anywhere between 0 and 100.

I've also made sure that my graphics card isn't doing anything to the
gamma signal in the display settings.

There's also a pale area in the centre of the screen that radiates out
to the corners getting darker as it goes.

I've not read of similar problems, but wondering whether it's duff or
just a cheap-ass TFT.

Cheers,
Nick

I have a LG L1720P. Black looks black to me. But it is a very bright monitor - I
use it with the color and brightness about as low as they will go, and only
adjust the contrast.

But as I said, black looks black, with no grey/purple. Perhaps its defective,
but you might play more with the brightness, color and gamma if you haven't
already done so.

Hi Bob,

Thanks for the info. I contacted LG and they say that they think it's a
defective unit, so I've applied for an RMA from the supplier. Should get
a replacement soon.

Cheers,
Nick
