General Definition
A monitor is anything that keeps track of something else. It can be a person, device, or program designed to observe and provide feedback on performance or progress.
Computers
- Program Monitor: A program that supervises the activity of other programs. This can include system monitors, which track the performance, utilization, and management of computer resources.
- Display Monitor: A device similar to a television set that accepts video signals from a computer and displays information on its screen. These can be characterized by various features such as screen size, resolution, refresh rate, and technology (like LCD, LED).
Examples
Program Monitor
- Task Manager (Windows): This built-in program in Windows operating systems allows users to see and manage currently running applications and background processes.
- Activity Monitor (macOS): A system monitoring application that displays information about the processes running on a Mac, including CPU usage, memory usage, disk activity, network activity, etc.
- Top (Linux): A command-line utility in Linux that provides a real-time overview of running system processes.
Display Monitor
- Desktop Monitors: Standard monitors used with desktop computers, such as the Dell Ultrasharp series, which often feature high resolutions and color accuracy.
- Gaming Monitors: Specialized monitors meant for gaming, such as the ASUS ROG series, featuring high refresh rates and low response times.
- Professional Monitors: Used in fields such as design or video editing, these monitors, such as the Eizo ColorEdge series, offer superior color accuracy and wide color gamuts.
Frequently Asked Questions
What is the difference between a CRT and an LCD monitor?
CRT (Cathode Ray Tube) monitors are bulky and use electron beams to display images on a phosphorescent screen. LCD (Liquid Crystal Display) monitors use liquid crystals and are slimmer, lighter, and more energy-efficient.
Can a monitor affect gaming performance?
Yes, a monitor’s refresh rate, response time, and resolution can significantly affect gaming performance by reducing lag and providing a smoother visual experience.
What does a program monitor do?
A program monitor keeps track of other running programs and system resources, ensuring efficient use and alerting users to potential issues like high CPU usage or insufficient memory.
How do I calibrate my monitor for accurate colors?
You can use built-in calibration tools in your operating system or third-party hardware calibration devices like the X-Rite i1Display to calibrate your monitor for accurate colors.
What is a 4K monitor?
A 4K monitor refers to a display with a resolution of approximately 3840 x 2160 pixels, offering enhanced detail and sharpness compared to lower-resolution monitors.
Do all computers require an external monitor?
No, laptops come with an integrated monitor, but desktop computers typically require an external monitor.
Are curved monitors better?
Curved monitors can provide an immersive experience and reduce eye strain by keeping the screen edges at a more consistent distance from the eyes.
What is a refresh rate?
The refresh rate, measured in Hertz (Hz), is the number of times a monitor updates with new information per second. Higher refresh rates can result in smoother motion and are particularly beneficial for games.
How important is monitor resolution?
Monitor resolution determines the number of pixels on the screen. Higher resolutions offer more detail and clarity, beneficial for tasks like graphic design, video editing, and gaming.
What are adaptive sync technologies?
Adaptive sync technologies like NVIDIA G-SYNC and AMD FreeSync synchronize the monitor’s refresh rate with the frame rate of the computer’s graphics card to reduce screen tearing and stuttering.
Related Terms
- Resolution: The number of pixels on the screen, usually noted as width x height (e.g., 1920x1080).
- Refresh Rate: The number of times the monitor updates the display per second, measured in Hz.
- Response Time: The time it takes for a pixel to change from one color to another, measured in milliseconds (ms).
- G-SYNC: A NVIDIA adaptive sync technology that prevents screen tearing.
- FreeSync: An AMD adaptive sync technology that minimizes screen tearing.
- Pixel Pitch: The distance between the centers of two adjacent pixels, affecting clarity and sharpness.
