Ok, you need to do some google searching. Just punch in exactly what you want to know ie "CRT dot pitch"
You want a high resolution , ie 1600X1200 is great and u want a low dot pitch .25 or lower.
Referring to the sharpness and clarity of an image, resolution is the term most often used to describe monitors, printers, and bit-mapped graphic images. In the case of dot-matrix and laser printers, the resolution indicates the number of dots per inch. For example, a 300-dpi (dots per inch) printer is one that is capable of printing 300 distinct dots in a line 1 inch long. This means it can print 90,000 dots per square inch.
For graphics monitors, the screen resolution signifies the number of dots (pixels) on the entire screen. A 640-by-480 pixel screen is capable of displaying 640 distinct dots on each of 480 lines, or about 300,000 pixels. This translates into different dpi measurements depending on the size of the screen. For example, a 15-inch VGA monitor (640x480) displays about 50 dots per inch.
Printers, monitors, scanners, and other I/O devices are often classified as high resolution, medium resolution, or low resolution. The actual resolution ranges for each of these grades is constantly shifting as the technology improves.

"Vertical Refresh Rate" or "Vertical Scan Rate" is the maximum number of frames that can be displayed on a monitor in a second, expressed in Hertz.
The scan rate is controlled by the vertical sync signal generated by the video controller, ordering the monitor to position the electron gun at the upper left corner of the raster, ready to paint another frame. It is limited by the monitor's maximum horizontal scan rate and the resolution, since higher resolution means more scan lines. Increasing the refresh rate decreases flickering, reducing eye strain, but few people notice any change above 60-72 Hz.
You've only looked at 2 monitors, I would look at more, and try to find some reviews. I've heard good things about Viewsonic and Samsungs. Good luck.
