18. Because of how the ____ monitor works - portions of the display tube cannot be used for displaying the image.






19. ____ panels offer the best contrast ratios of the display types - and are well suited for movies that require good contrast.






20. It is common for ____ monitors to support a wide number of resolutions - but LCD monitors often have a____ (optimum) display resolution.






21. ____ is drawing the screen in two passes; odd lines on the first and then the even lines on the second pass.






22. TN panels have poor color reproduction due to the fact that only ____-bits per color can be displayed. They mimic true 24-bit color using dithering and other techniques.
