With the advent of sleeker flat-panel LCD displays and the gradual decline in CRT monitor prices, consumers now have the opportunity to enhance their desktop experience with larger screens or more desk space. This guide will delve into the factors to consider when choosing between an LCD and a CRT monitor, the features that matter, and the price ranges you can expect.
When it comes to selecting a new monitor, the primary consideration is whether you value desktop real estate or screen size more. If desk space is at a premium, an LCD's slim profile is the way to go. However, if you're on a budget, CRT monitors, which are bulkier, might be more appealing despite their larger footprint.
Many consumers purchase desktop computers and monitors as a bundle, but there's a growing trend of keeping an existing monitor when buying a new desktop or upgrading the monitor for an existing setup.
Major computer brands like Apple, Dell, Hewlett-Packard, and Sony offer their own monitors, often designed to complement their desktop systems. Other brands such as Samsung, NEC, and ViewSonic sell monitors separately, with many being manufactured by outsourced companies.
CRT monitors, once the standard, are now less common but still available in sizes from 17 to 21 inches. They have a nominal image size, which is the diagonal measurement of the tube, and a slightly smaller viewable image size (VIS). For example, a 17-inch CRT typically has a 16-inch VIS. Due to a class-action lawsuit, advertisements must now clearly state both the nominal and VIS sizes.
The larger the CRT, the more desk space it consumes, with depth often matching the screen size. However, "short-depth" models can save an inch or more of desk space. A 17-inch CRT, which is a popular choice, offers about one-third more viewable area than the now less common 15-inch models. For those working with graphics or large spreadsheets, a 19-inch monitor, which has a viewable area one-fourth larger than a 17-inch model, might be ideal. The largest models, aimed at professionals, are 21- and 22-inch monitors that provide extensive viewing areas but require significant desk space.
LCD monitors began outselling CRTs in 2003, according to a report by DisplaySearch (now part of IHS Markit). They are thinner, lighter, and consume less desk space. LCDs operate with either analog or digital input, and their nominal and viewable image sizes are the same. A typical 15-inch LCD is just a few inches deep and weighs around 15 pounds, compared to 30-50 pounds for a CRT. Larger LCDs are available, but they come with a higher price tag. Wide-screen LCDs, designed for watching wide-format videos, have a 16:9 aspect ratio similar to digital TVs.
While LCDs offer a clear image, they have a narrower color range than CRTs and require a direct viewing angle to avoid contrast loss. Fine lines may appear grainy on an LCD, especially in analog mode, which requires adjustments for optimal picture quality.
The resolution of a monitor indicates the number of pixels that compose an image. Higher resolutions equate to finer detail. Most monitors support multiple resolutions, typically ranging from 640x480 to 1,600x1,200, depending on the monitor and graphics card. LCDs tend to display sharper images at their native resolution, which is 1,024x768 pixels for a 15-inch screen and 1,280x1,024 or 1,400x1,050 for larger models. Higher resolutions on both CRT and LCD monitors result in smaller text and images, allowing more content to fit on the screen.
Dot pitch, measured in millimeters, is the distance between pixels on a CRT monitor. A smaller dot pitch generally means a more detailed image. It's advisable to avoid CRTs with a dot pitch higher than 0.28 mm. CRTs also require a high refresh rate to prevent image flicker, with a recommended rate of at least 75 Hz for a 17-inch monitor and 85 Hz for a 19-inch monitor to minimize eyestrain. Refresh rate is not a concern for LCDs.
Larger CRTs consume more power, with a 19-inch model using about 80 watts, compared to 65-70 watts for a 17-inch model and around 20 watts for a 15-inch LCD. Most monitors have a sleep mode that reduces power consumption to less than 3 watts when not in use.
Some monitors come with built-in microphones, speakers, or composite-video inputs for connecting external devices. Plug-and-play capability simplifies the process of adding a new monitor to an existing computer.
When deciding between an LCD and a CRT monitor, consider the space available on your desk and your budget. If desk space is limited, an LCD is the better choice, albeit at a higher cost. For those who prioritize budget over space, a CRT monitor remains a viable option.
For most users, a 15-inch LCD or a 17-inch CRT will suffice. Larger monitors are beneficial for those who need to view photo enlargements or work with multiple windows simultaneously. Features such as adjustable height, rotation capability, and a long warranty can also influence your decision.
