  Any tips on which to buy?
  
  Something I saw:

  
  - 20" diagonal
  - Max Resolution: 1680 x 1050
  - Contrast Ratio: 800:1
  - Brightness: 300 cd/m2

  For the contrast ratio, what does it means? The smaller(200:1) better or the larger (1000:1) better?
  *example
  
  Then for the brightness, what does it means? Whats cd? whats m2? Then is it smaller(100cd/m2) better or (500cd/m2) better?
  *example

  1st qn
  more info here
  i dunno wad wikipedia mean so just give u link
  
  2nd qn...
  cd/m² = candela per square metre = luminance
  more info here
  

  Luminance is used in the video industry to characterize the brightness of displays. In this industry, one candela per square metre is commonly called a "nit". A typical computer display emits between 50 and 300 nits.

  therefore, i think 300 cd/m² is the maximum brightness a com can have

  contrast ration in theory the higher the better. contrast ration is generally the difference between the darkest black and the purest white. the higher this value the more desirable it should be. a pc with true higher coontrast ratio avoids darker patches when u watch movies during dark night scenes or play games like doom or any other stealth games that lurks in the dark.
  
  brightness cd/m2 also equals to nits. usually the higher the value indicates more poowerful backlit, which also means a little higher power consumption with the LCD. i think i saw LCD with 350 nits specification before, just google it and u will know.
  
  If u are an existing LCD owner it helps if you note the specification and compare it with the specification on another newer lCD model u intedn to buy. since u are used to your existing LCD, getting a new unit with better rated specs over your exist one should put u on a safe side in purchase satisfaction.
  
  still nothing match the vibrant color of an 8-bit panel. That is the reason why i still keep an old 15inch LCD with slow response time for watch TV.
