7 Important Things To Know When Buying An LCD Monitor
Considering an Upgrade? Understanding LCD Monitors
Is your current computer monitor failing to meet your needs? Perhaps it’s time to explore the benefits of a new one, specifically liquid crystal display (LCD) monitors, commonly referred to as flatscreens.
The technology behind LCDs isn't new. It has been implemented in devices like digital clocks and laptop screens for quite some time.
The Rise of LCDs
In recent years, LCDs have become the prevailing standard for desktop computer monitors. Simultaneously, they have also become dominant in the television industry.
Compared to older CRT (cathode ray tube) monitors, flatscreen displays offer significant advantages.
Key Advantages of Flatscreen Monitors
- They are considerably thinner and lighter.
- Energy consumption is reduced.
- They produce no electromagnetic radiation.
Furthermore, the technology allows for sharper images, increased resolutions, and a display free from flicker, resulting in reduced eye strain.
These benefits represent compelling reasons to transition away from older CRT technology.
What This Article Covers
This article will detail the various characteristics of monitors, with a particular focus on flatscreens. It aims to provide you with the knowledge necessary to make an informed decision when purchasing a new LCD computer monitor.
We will explore the important factors to consider, ensuring you select a monitor that perfectly suits your requirements.
Screen Dimensions
A monitor's screen size is determined by the diagonal measurement, extending from the lower-left to the upper-right edge of the display area. Current offerings span from 15 inches up to 30 inches.
The prevalent screen size for desktop monitors presently falls between 19 and 22 inches, though larger options are frequently purchased.
Generally, an increased screen size provides a more expansive desktop workspace. This allows for the simultaneous viewing of numerous open applications and windows.
Conversely, larger monitors require a greater amount of desk space and typically command a higher price point.
Aspect Ratio Explained
The aspect ratio defines the proportional relationship between the width and height of a display, expressed as a ratio of horizontal to vertical pixels.
Historically, traditional cathode ray tube (CRT) monitors were nearly square, typically featuring a 4:3 aspect ratio.
Modern Display Standards
Currently, widescreen displays are prevalent, mirroring the proportions found in cinemas, such as 16:9 or 16:10.
The 16:9 aspect ratio is frequently referred to as HD, or high definition.
Benefits of Widescreen Displays
Utilizing a widescreen monitor eliminates the black bars often seen when viewing DVDs on a computer.
Wider ratios also provide a more efficient layout for multitasking, allowing for the simultaneous viewing of multiple windows.
When to Choose a 4:3 Aspect Ratio
Opting for a 4:3 display is generally only recommended if personal preference dictates it, or if desk space is limited.
In these cases, a wider monitor may not be practical.
Key Considerations
- Aspect Ratio: The relationship between width and height.
- 4:3: Traditional, square-like display.
- 16:9/16:10: Widescreen formats, ideal for modern content.
Resolution Explained
Resolution refers to the density of pixels displayed across a screen's width and height. For LCD screens, there exists a single, optimal or native resolution. This native resolution precisely defines the total pixel count in both dimensions.
In contrast to older CRT monitors, operating a flatscreen at a resolution below its native setting results in a noticeably blurred picture. Selecting the appropriate native resolution initially is therefore crucial, as compromising on this aspect will inevitably degrade image quality.
A greater resolution translates to more detailed visuals, enhanced clarity, and an expanded workspace. This is particularly beneficial for users who frequently engage in multitasking or enjoy viewing films on their computers.
However, increased resolution also means smaller text, which can be problematic for individuals with visual impairments. Therefore, a high resolution may not be ideal if your vision is not optimal.

Consider the following when choosing a resolution:
- Higher resolutions offer greater detail.
- Lower resolutions are easier on the eyes.
- Native resolution is key for optimal image quality.
Contrast Ratio Explained
The contrast ratio quantifies the distinction between the purest white and the deepest black that a liquid crystal display (LCD) monitor is capable of rendering.
A greater contrast ratio results in brighter whites, darker blacks, and a wider spectrum of grayscale shades. A ratio of 1,000:1 is generally considered optimal.
Understanding the Complexity
Evaluating contrast ratios can be surprisingly complex. Direct comparisons of specifications across different manufacturers are often unreliable.
Furthermore, the term "dynamic contrast" is frequently encountered, but it's crucial to understand that this differs significantly from the standard contrast ratio and can be misleading.
Dynamic vs. Static Contrast
It's important to differentiate between static and dynamic contrast ratios. Static contrast represents the true difference between black and white at a given moment.
Dynamic contrast, conversely, is a marketing figure that indicates the highest possible contrast achievable under ideal, and often unrealistic, conditions.
- Static Contrast: A consistent measurement of black to white.
- Dynamic Contrast: A peak measurement, often inflated for marketing purposes.
Therefore, when assessing monitor quality, prioritize the static contrast ratio for a more accurate understanding of its performance. A higher static ratio generally indicates a better viewing experience.
Brightness
Liquid crystal displays rely on backlights to produce visible images. Brightness, a key characteristic of these displays, is quantified in candelas per square meter (cd/m2).
Generally, a brightness level of at least 300 cd/m2 is recommended for activities like gaming or movie viewing. This higher intensity enhances the visual experience.
However, for typical office tasks and web browsing, a brightness range of 200 to 250 cd/m2 is usually sufficient. Lower levels are adequate for these applications.
Therefore, the optimal brightness setting depends on the intended use of the LCD monitor. Consider your primary activities when selecting a display.
Understanding Brightness Levels
- 300 cd/m2 or higher: Ideal for gaming and watching movies.
- 200-250 cd/m2: Suitable for office work and general web browsing.
Choosing the appropriate brightness ensures comfortable viewing and optimal image quality. It's a crucial factor in overall user experience.
The measurement of brightness in cd/m2 allows for a standardized comparison between different LCD monitors. This facilitates informed purchasing decisions.
Viewing Angle Considerations
A wider viewing angle enhances visibility for individuals positioned to the side of the monitor. In comparison to older Cathode Ray Tube (CRT) displays, Liquid Crystal Displays (LCDs) often exhibit a more restricted viewing angle.
However, the significance of this specification is contingent upon anticipated usage scenarios. If you and others will consistently view the monitor directly from the front, this characteristic may be of minimal importance.
Understanding the Impact
The viewing angle determines how clearly the image remains visible when observed from off-center positions. A broader angle ensures consistent image quality even when not directly facing the screen.
Consider the typical viewing positions in your environment. If collaborative work or viewing from various locations is common, a wider viewing angle is highly recommended.
Conversely, for individual use where a direct frontal view is standard, prioritizing other monitor specifications may be more beneficial.
LCDs, while offering numerous advantages, historically presented limitations in viewing angles compared to CRTs. Modern LCD technology has significantly improved this aspect, but it remains a factor to consider.
Ultimately, assessing your specific needs will dictate whether a wide viewing angle is a crucial feature for your new monitor.
Ports
Up until now, our focus has been solely on the display itself and the underlying LCD technology. However, a monitor represents more than simply a visual surface. It requires connection to a computer, and potentially other devices as well.
Therefore, understanding the necessary port types and verifying their availability on the monitor is crucial. Confirming compatibility with your video card’s connectors is also essential.
Here’s a concise overview of the most frequently encountered port types:
- DisplayPort: A modern digital display interface, available since 2008.
- HDMI: Stands for High-Definition Multimedia Interface, a digital audio/video connection established in 2003.
- DVI: Abbreviation for Digital Video Interface, representing the initial digital video standard. It was introduced in 1999 as a replacement for VGA.
- VGA: Represents Video Graphics Array, an older analog connector first released in 1987.
The following image illustrates the ports discussed above. Displayed from left to right are: DisplayPort (colored blue), HDMI (black), VGA (white), and DVI (white).
Beyond these primary connections, you might also encounter component video, S-video, and composite video ports.
Response time is a specification that can often be overlooked, and panel technology becomes less significant once you’ve determined your preferences regarding the previously discussed features.
In conclusion, begin by selecting a desired screen size, aspect ratio, and resolution. These characteristics should align with your specific requirements.
Subsequently, compare available models based on key features, with particular attention to contrast ratio, brightness, and the available port selection. Ultimately, your budget will determine the final model you choose.
