Final Thoughts
As we move forward in the world of computer displays, it’s essential to remember the legacy of CRT technology.

Whether you’re looking for a retro gaming experience or a high-quality display for professional applications, CRT monitors are still worth considering.
What is a CRT monitor and how does it work?
A CRT (Cathode Ray Tube) monitor is an older type of display technology that uses an electron gun to shoot beams of electrons onto a phosphorescent coating on the inside of a glass tube, creating images on the screen. The electron gun is controlled by a magnetic field that deflects the electron beams horizontally and vertically, allowing the creation of a wide range of colors and images.
The CRT monitor’s technology relies on the principle of persistence of vision, where the human eye retains an image for a fraction of a second, allowing the creation of motion pictures by rapidly displaying a sequence of still images. Although CRT monitors have largely been replaced by newer technologies such as LCD and LED displays, they are still valued by some for their unique characteristics, such as their ability to display a wide range of colors and their fast response time.
Are CRT monitors still being manufactured?
Although CRT monitors are no longer widely manufactured, there are still some companies that produce them, mainly for specialized applications such as medical imaging, industrial control systems, and nostalgic gaming. These companies often produce CRT monitors in small quantities and may customize them to meet specific customer requirements.
Some examples of companies that still manufacture CRT monitors include Japanese companies such as Toshiba and Hitachi, as well as some smaller, specialized manufacturers in Asia and Europe. However, the availability of CRT monitors is limited, and they are often more expensive than newer display technologies.
What are the advantages of CRT monitors?
CRT monitors have several advantages that make them still desirable for certain applications. One of the main advantages is their fast response time, which makes them well-suited for fast-paced video games and other applications that require quick motion. CRT monitors also have a wide viewing angle, which means that the image remains clear and vibrant even when viewed from the side.
Another advantage of CRT monitors is their ability to display a wide range of colors, making them well-suited for applications such as graphic design and video editing. Additionally, CRT monitors are often preferred by gamers for their low input lag, which means that the delay between the time a signal is sent to the monitor and the time it is displayed is minimal.
What are the disadvantages of CRT monitors?
One of the main disadvantages of CRT monitors is their size and weight. CRT monitors are typically larger and heavier than newer display technologies, making them more difficult to move and install. They also require more power to operate, which can increase energy costs and heat generation.
Another disadvantage of CRT monitors is their limited lifespan. The phosphorescent coating on the inside of the CRT can degrade over time, reducing the brightness and color accuracy of the display. Additionally, CRT monitors are more prone to screen burn-in, which can cause permanent damage to the display if the same image is displayed for an extended period.
Can I still buy a CRT monitor?
Although CRT monitors are no longer widely available, it is still possible to buy them from some specialized retailers and online marketplaces. Some companies specialize in refurbishing and selling used CRT monitors, which can be a cost-effective option for those who need a CRT monitor for a specific application.
When buying a CRT monitor, it’s essential to ensure that it is compatible with your computer or other devices and that it meets your specific needs. It’s also crucial to check the warranty and support offered by the seller, as CRT monitors can be more difficult to repair and maintain than newer display technologies.
How do I care for and maintain my CRT monitor?
To extend the lifespan of your CRT monitor, it’s essential to care for and maintain it properly. This includes avoiding exposure to extreme temperatures, humidity, and physical shock. It’s also crucial to clean the monitor regularly using a soft cloth and avoid touching the screen, as oils from your skin can damage the phosphorescent coating.
Additionally, it’s recommended to adjust the monitor’s brightness and contrast settings regularly to avoid screen burn-in. It’s also a good idea to turn off the monitor when not in use to reduce wear and tear on the CRT. By following these tips, you can help extend the lifespan of your CRT monitor and ensure it continues to function properly.
What are some alternatives to CRT monitors?
For those who need a display technology with similar characteristics to CRT monitors, there are several alternatives available. One option is OLED (Organic Light-Emitting Diode) displays, which offer fast response times, wide viewing angles, and high color accuracy.
Another option is TN (Twisted Nematic) LCD displays, which offer fast response times and low input lag, making them well-suited for gaming and other applications that require quick motion. Additionally, some modern LCD displays use technologies such as IPS (In-Plane Switching) and VA (Vertical Alignment) panels, which offer wide viewing angles and high color accuracy, making them suitable for applications such as graphic design and video editing.
