How Monitors are Measured
When it comes to buying a monitor, understanding the various measurement standards is crucial to ensure that you get a display that fits your needs. In this article, we’ll dive into the world of monitor measurements, explaining the different ways they’re evaluated and how to make an informed decision.
The Basic Measurements
Before we dive into the intricacies of monitor measurements, let’s cover the basic terms:
- Resolution: This is the number of pixels or picture elements that make up the display. It’s usually expressed in pixels (e.g., 1920 x 1080 for a Full HD monitor).
- Refresh Rate: This is the number of times the monitor updates the image per second, measured in Hz (e.g., 60Hz, 144Hz, or 240Hz).
- Aspect Ratio: This is the proportion of the display’s width to its height, typically expressed as 4:3, 16:9, or 21:9.
- Screen Size: Measured in inches, this is the diagonal distance from corner to corner of the monitor.
Display Panel Types
Monitors can be categorized into several types, each with its strengths and weaknesses:
- TN (Twisted Nematic): Known for their high response time and low input lag, TN panels are suitable for fast-paced games and applications.
- IPS (In-Plane Switching): These panels offer improved color accuracy and wider viewing angles, making them suitable for graphics design, video editing, and color-sensitive work.
- VA (Vertical Alignment): VA panels are known for their high contrast ratio and deep blacks, making them ideal for movie enthusiasts.
- OLED (Organic Light-Emitting Diode): OLED panels use organic compounds to produce light, providing excellent contrast and viewing angles, but can be more expensive and prone to burn-in.

| Size (Diagonal) | 4:3 | 16:9 | 21:9 |
|---|---|---|---|
| 19 inches | 14.7 inches | 19.5 inches | 24.2 inches |
| 24 inches | 18.4 inches | 24.8 inches | 32.4 inches |
| 27 inches | 20.7 inches | 27.5 inches | 36.1 inches |
| 32 inches | 22.9 inches | 32.4 inches | 41.1 inches |
Viewing Angle and Response Time
When evaluating a monitor, consider the following aspects:
- Viewing Angle: How well the display maintains its color accuracy and brightness when viewed from the side or above.
- Response Time: How quickly the monitor can update the image to reduce motion blur and ghosting.
Other Key Measurements
- Contrast Ratio: The difference between the brightest and darkest elements on the display.
- 峰值照明 (candelax): A measure of a monitor’s brightness, typically measured in cd/m².
- Color Gamut: The range of colors the monitor can display, measured in percentages of the NTSC (National Television System Committee) color gamut.
Making an Informed Decision
When choosing a monitor, consider the following:
- Purpose: What will you be using the monitor for? (gaming, video editing, general browsing)?
- Budget: Set a budget and stick to it.
- Display Type: Consider the type of display panel suitable for your needs (TN, IPS, VA, OLED).
- Viewing Angle: Take into account the desired viewing angle range.
- Response Time: Check the response time for fast-paced applications.
- Resolution and Refresh Rate: Choose a monitor with a suitable resolution (e.g., 4K for high-definition content, 1080p for gaming) and refresh rate (e.g., 60Hz for gaming, 144Hz for fast-paced gaming).
By understanding the various ways in which monitors are measured, you can make an informed decision and find the perfect display for your needs. Don’t let the jargon overwhelm you – take the time to research and compare different models, and you’ll be enjoying your new monitor in no time!
