What are the key features of CAD monitors?

Monitors can be tricky and have a complicated history. There are many options when it comes to replacing or adding a monitor. These include Thunderbolt interfaces, serial and IPS LED. Here are some CAD tips to help you find the perfect monitor for your needs.


The interface is the plug that connects to your computer at the end. The motherboard houses one half of the interface, while the other is on your device. The serial port is the oldest and most widely used interface. It has three rows of five pins. This type of monitor’s VGA port is available as a default on the motherboard. Any old or new monitor that has the port will work with it. Make sure the pins on second-hand monitors are straight and present if you’re looking to buy them. To check for pins missing, revit gently brush your fingertip using moderate pressure.


Cathode Ray Tubes (CRT)

The first monitors that were made available to the public were CRT monitors. They had serial interfaces and looked TV-like due to the extruding back that held the Tube inside. Combining serial and CRT provided basic display functionality. These are smaller than the current products on the market and only available with serial VGA interfaces.

Liquid Crystal Displays (LCD)

Flat screen technology was introduced to the market by LCDs. You can identify LCDs by pressing down lightly on the screen. The screen is plastic-like and bends at pressure. Colors distort when the screen is under pressure. These screens are very thin and do not have a glass display. This makes them laptop-friendly. You can find LCDs in sizes ranging from 13″ to 40″. There are many interface options.

Light Emitting Diodes (LED) Displays

The next step in LCD technology was LED displays. They offer more functionality and aesthetic options. LED displays use smaller LEDs to power the pixels. They can display extremely high resolutions. The light-emitting nature LEDs makes it possible to display contrast functions and other features that were not available in older technologies. Similar to LCDs, LEDs are available in different sizes and interface options. However, they come at a slightly higher cost.

2D Displays vs. 3D displays

2D displays display everything in 2D. The optical illusions, exploits and mind-eye coordination allow you to see the 3D reality in depth. The following 2D display technologies are either new or less well-known, and include the LCD, LED, CRT, and LCD.

  • Electroluminescent display (ELD)
  • Electronic paper, E-Ink
  • Plasma display panel (PDP)
  • High-Performance Addressing display (HPA)
  • TFT (thin-film transistor display)
  • Organic light-emitting diode (OLED),
  • Surface-conduction electron-emitter display (SED) – (experimental)
  • Field emission display (FED – Experimental)
  • Laser TV (forthcoming).
  • Carbon nanotubes – (experimental)
  • Quantum dot display – (experimental)
  • Interferometric modulator Display (IMOD).
  • Digital Micro Shutter display (DMS)

Viewing modes

Landscape and portrait are more than orientations. They have a significant influence on the layout of multiple displays or special monitors, such as kiosk displays. People still use portrait mode monitors to display their work, for example portrait photographers who digitally master the shoots. You can find more information on setting up multiple displays in our comments section.

Checking Display Units

The display is the most important component of the package. Technology can come and go but the display must be eligible. If you are looking for “burns”, which are dead pixels, or second-hand or refurbished units, these will be the signs. They will be easier to find if you have a solid background. This is also true if you are trying to verify color consistency. It will likely appear around the edges or ends of your screen, but it is not desirable. You can use fast moving colors, animations and videos to test how adaptable your display technology is after the previous owner has had it.


Monitors are a gamble because no technology is static enough to prevent newer models from popping up every day. It can be difficult to choose a monitor due to the fact that the display unit is as important as the computer itself. We hope this guide will help you to understand the basics of window shopping and actual shopping.
