Maximum Resolution 1680 x 1050
Your resolution. Vertical pixels by horizontal pixels. Higher resolutions make images smaller and sharper, while lower resolutions will make images larger but more "pixelated", and you won't be able to fit as much on the screen as with higher resolutions. Most prefer higher resolutions.
Recommended Resolution 1680 x 1050
This is the physical amount of pixels the monitor has. With LCDs it's pretty much required that you use the recommended resolution (which is typically also the maximum).
Viewing Angle 170°(H) / 160°(V)
This is the manufacturer's claim of how far off to the side or above you can view the image on the monitor without the picture's colors becoming distorted. Higher is better, but take this rating with a grain of salt as manufacturers can claim whatever they like.
Pixel Pitch 0.282mm
www.google.com. Smaller is better.
Display Colors 16.2 Million
Literally the number of colors the monitor can display. Higher is better. 16.X million is typical for TN panels.
Brightness 300 cd/m2
Higher is brighter. 300 cd/m2 is typical for 19" - 22" LCDs
Contrast Ratio DC 2000:1(1000:1)
In theory, this means that the brightest color the monitor can display is 2000 times brighter than the darkest color (LCD panels can't display true black or true white). Take this rating with a grain of salt as well, there is no official system manufacturers have to adhere to. Higher is better (10,000:1 > 700:1). DC stands for Dynamic Contrast; it's one of Samsung's ways of lying to its customers. It basically means that it can display a pixel 2000 times brighter than another pixel, just not at the same time. If a company uses this rating it's a good hint that it's a slimy company that probably uses Samsung panels and should be avoided.
Response Time 2ms(GTG)
Time the pixel takes to change colors in milliseconds (again, in theory). Lower is better. (GTG) is also Samsung's way of blatantly lying to its customers. It stands for grey to grey (meaning that they measure the fastest response time possible instead of calculating a healthy average). The real response time of this monitor, for instance, is 5ms.
Horizontal Refresh Rate 31.3 - 80.2KHz
This will be typical of all LCD panels.
Vertical Refresh Rate 56 - 75Hz
So will this.
Display Type WSXGA+
This just means it's a widescreen.
