Black value significance

[nandu26]

I want to know the significance of black values as mentioned on the notebookcheck reviews.

Which of the following black values are better?

Inspiron 1545 - 1.29 cd/m² (This is my current laptop)
Contrast: 159:1

Planning to buy

Inspiron 15R 5537 - 0.45 cd/m²
Contrast: 433:1

Lenovo Z510 - 0.97 cd/m²
Contrast: 327:1

Lenovo Y510P - 0.65 cd/m²

My maximum budget is 55K. I read a lot on the web, ebooks etc. So I want a laptop which has crystal clear text.

I am also considering HP Pavilion 15 but I don't know about its black values.
Please clarify

I got some comparison pics of Lenovo Y500(almost same as Y510p) and Dell Inspiron 15 if you want. I have compared display angle and color reproduction at max brightness and in a well lit room.

BTW I think haven't you been considering buying a laptop for a long time now?
