Acer wrapped up the week today by rolling out a new high-performance desktop LCD that appears first in Japan. The 24-inch S243HL uses a white LED backlight that provides it with an extremely high contrast ratio even when compared to typical LED-lit displays, jumping from 1,000:1 to 8,000,000:1 with dynamic contrast active. The thinner technology also contributes to a main panel that measures about 0.57 inches thick, although the base is thicker.
