Displays

A quality display can make a big difference to users who edit images digitally for Web posting or printing. A low-resolution display will not display images as sharply as higher-resolution models, and users with little desk space might enjoy less bulky displays. Look here for a comparison of cathode ray tube (CRT) and liquid crystal display (LCD) displays, size recommendations, resolution information and more.

FAQ

How are CRT displays different from LCD displays?
The technologies behind CRT and LCD displays differ completely. A CRT display, often compared to a television picture tube, is the most common display; while LCD displays, or flat panel displays, have evolved from the laptop to the desktop. The primary differences between the two display types include:

• Viewable image versus screen size
  The viewable image on a CRT is generally one inch smaller than the screen size; on an LCD, the screen size and viewable image are the same.
   
• Desktop space covered
  CRT displays are bulkier than LCD displays, covering more desk space and weighing much more than the flat panel displays.
   
• Cost
  LCD displays are considerably more expensive than the popular CRT displays, ranging from approximately $700 to $3000, while CRT displays usually cost between $150 and $1,000.

What resolution is recommended for displaying digital images?
Monitor resolution is defined as pixels per inch (ppi). As resolution increases (number of ppi), so does the amount of information displayed. Generally, 1,024 x 768 resolution is recommended.

What size display should I choose?
Large displays allow higher resolution than small displays, enabling the viewer to see more on-screen information. Common sizes include 15, 17, 19 and 21-inch models. A 17-inch display should be sufficient for displaying digital images, though larger displays are optimal.  If your work involves programs with many floating menus such as Photoshop, consider a display of 19" or larger.  This will leave you plenty of workspace while keeping all menus visible.

Which types of displays are ideal for users on a budget?
Affordable CRT displays are perfect for users who need to watch their wallets. Although 15-inch displays are the least expensive, the 17-inch models offer better resolution at reasonable prices — often as low as $150.

Why is refresh rate important?
High refresh rates reduce screen flicker and eye strain. A 75-MHz or higher refresh rate is recommended for a CRT display.
