Best monitor for 60 - 90 $

Looks like you don't have much of a choice in this price range for a decent resolution. You're looking for LED-backlighting, a (1000:1) contrast ratio, and preferably a DVI input at 1440x900 or 1600x900. You should be able to find a deal somewhere online.

EDIT - ^^^That is an amazing deal - don't forget to put in the promo code when purchasing!
