Contrast Ratio and Trying to Find the Same Monitor

I have these two monitors now Gateway FHX2402L with these specs:

Display 24-inch widescreen LCD

Active Display Area 20.92 × 11.76 inches (531.30 × 298.80 mm)

Maximum Resolution 1920 × 1080

Maximum Refresh Rate 60 Hz

Response Time 2 ms

Contrast Ratio Dynamic: 12,000,000:1

Brightness 250 cd/m2

Viewing Angles Horizonal: 176°Vertical: 176°

Number of Colors 16.7 million

Inputs One VGA port One HDMI port with HDCP One DVI port

I want to add a third but I can't find it anywhere. This model I think is discontinued.If anyone can find that exact same monitor I will make mad passionate love with you.

The closest one I could find is this model:

The contrast is 2 million less than the gateway but it has the exact same brightness. Wondering if I'm going to notice a difference like that?
