what about contrast ratio of monitor?

[SAKIB SANI]

how difference between 600:1 vs 1000000:1 on monitor?

theres no sure fire way to tell the difference as each manufacturer uses there own measurements for ct ratios.

typically though 800:1 normally is comparable to 10,000:1 or 100,000:1

Contrast is comparing white to black level. The difference in numbers comes from static vs dynamic contrast ratios and you cannot have a comparable ratio of the 2. You can have 1,000,000,000 to 1 and a 10,000 to 1 have the same 800:1 static. Dynamic changes brightness so a low brightness will have a darker black and a high brightness will have a lighter white, making dynamic higher. Static is comparing white and black at the same brightness level which is what you'd really see when using it. Most usually state 1000:1 static even if they are not but it's just marketing. Like all other monitor specs, they are not regulated and cannot be trusted.

There are two types of contrast ratio.

Static contrast ratio is the "real" contrast ratio, typically it will be from about 600:1 on cheap generic monitors, to about 1000:1 on better TN panels and IPS monitors, to about 3000:1-5000:1 on good VA monitors. 5000:1 is a very excellent contrast ratio.

Then there is dynamic contrast ratio, which are numbers you see like 100,000:1 or 50,000,000:1. Dynamic contrast ratios are essentially made-up numbers which mean nothing, and you should ignore them completely.
