Hi,

LCD contrast numbers like 1:300, 1:500, etc. What does that mean?

TIA,

Conrad

It means that a pure white pixel is 300 times brighter than a pure black pixel.
It's a measure of the maximum contrast the display is capable of achieving.

It is the amount of "shades" the LCD screen can show between pure white and
black ......so the higher the number the better!
300 - 400 is the average. If you can find one that does 700 or greater then
this will be superb for Photoshop, they are out there!

Hi,

Thanks for your answer to my question. I was just reading that expectations are
1:1000 by next year on LCD monitors.

Best,

Conrad

Absolute rubbish. Tacit has the right answer. Your LCD can display at
most 254 shades between black and white.

What's typical of a pro quality CRT monitor? I've never seen that ratio
advertised in conjunction with CRT monitors. Is there a reason?

The Samsung 193P and Eizo L768 (same panel, I believe) already
claim 1:1000.

Latest Eizo does 1:1000 ;-)

No, the number of shades the monitor can display is a function of the video
card, and in any event all consumer RGB monitors display the same number of
shades (256 discrete shades in each of the three color channels, for a total of
just over sixteen million discrete colors).

It is a measure of the difference in brightness between the darkest black and
brightest white the monitor displays--that is, a measure of *contrast*--not a
measure of the number of shades of color the monitor can display.
