Today’s diverse monitor landscape offers a variety of choices to cater to different needs and budgets. Let’s delve into the most common types of computer monitors:

1. LCD (Liquid Crystal Display) Monitors:

The mainstay:

  • LCD (Liquid Crystal Display): The most common and affordable type, LCDs use liquid crystals that manipulate light to form images. They offer good image quality, energy efficiency, and a wide range of sizes and resolutions.

LCDs have dominated the market for decades, known for their affordability, good image quality, and energy efficiency.

Tech behind it:

Liquid crystals manipulate light to create images, illuminated by backlighting (either CCFL or LED).


    • TN (Twisted Nematic):

      Most affordable, but have limited viewing angles and color accuracy.

    • VA (Vertical Alignment):

      Better contrast and viewing angles than TN, but slower response times.

    • IPS (In-Plane Switching):

      Best color accuracy and viewing angles, but more expensive.

2. LED (Light-Emitting Diode) Monitors:

An LCD sub-type:


LED (Light-Emitting Diode): Technically, all modern LCD monitors use LED backlighting for superior brightness, color accuracy, and slimmer profiles compared to older CCFL backlighting.

Essentially LCDs with LED backlighting, offering superior energy efficiency and often better contrast and brightness.

3. OLED (Organic Light-Emitting Diode) Monitors:

High-end experience:

OLED (Organic Light-Emitting Diode): High-end displays known for their exceptional image quality with perfect blacks, high contrast ratios, and wide viewing angles. However, they can be more expensive and susceptible to burn-in.

Self-emissive pixels offer exceptional image quality, with perfect blacks, infinite contrast, and incredibly fast response times.

Premium price:

Significantly more expensive than LCD/LED counterparts.

Burn-in concerns:

Static images can leave permanent imprints, requiring careful usage.

4. Plasma Monitors:

  • Once a contender:

    Offered vibrant colors and deep blacks, but suffered from burn-in, high power consumption, and limited sizes.

  • Discontinued:

    No longer commercially available due to technological advancements and market shifts.

Immersive experience:


Curved: Creates a more immersive viewing experience, especially for gaming and design work, by minimizing distortion at the edges.

The curved screen fills your field of view, enhancing immersion in games and entertainment.

Available in LCD, LED, and OLED:

The panel technology doesn’t affect the curved form factor.


Not ideal for all tasks, especially productivity work involving text or spreadsheets.

Choosing the Right Monitor:

With this diverse range, selecting the perfect monitor depends on your priorities and budget. Consider factors like:

1. Primary Use:

  • Gaming:

     Prioritize high refresh rates (144Hz or higher), fast response times (5ms or below), and G-Sync/FreeSync compatibility for smooth, tear-free visuals. Consider curved displays for an immersive experience.

  • Professional Work:

     Opt for high resolutions (4K or 8K) for sharp details, wide color gamuts for accurate color representation, and IPS panels for wide viewing angles.

  • General Use:

     Focus on a balance between resolution, refresh rate, and panel type depending on your budget. 1080p with a 60Hz refresh rate is often sufficient, but consider higher specs if you enjoy watching movies or multitasking.

2. Size and Resolution:

  • Screen size:

     24-27 inches for standard use, 32-34 inches for multitasking or immersive gaming, consider viewing distance and desk space.
  • Resolution:

     1080p is fine for basic use, 1440p offers a good balance, and 4K/8K provide exceptional sharpness for large screens or professional needs. Remember, higher resolution requires more powerful graphics cards.

3. Panel Technology:

  • TN: Affordable, fast response times, limited viewing angles and color accuracy. Not ideal for professional work.
  • IPS: Great color accuracy and viewing angles, slower response times compared to TN. Suitable for most users.
  • VA: Deep blacks and high contrast, good for dark environments, slower response times than IPS.
  • OLED: Exceptional image quality, perfect blacks, wide viewing angles, expensive, susceptible to burn-in.

4. Refresh Rate and Response Time:

  • Refresh rate:

     How often the image updates per second (Hz). Higher refresh rates (144Hz+) are crucial for smooth visuals in fast-paced games. 60Hz is sufficient for basic use.
  • Response time:

     How fast pixels change color (ms). Lower response times (5ms or below) minimize ghosting and blurring in fast-paced visuals.

Other Features:

  • Ports: Ensure compatibility with your computer (HDMI, DisplayPort).
  • Ergonomics: Adjustable stand for comfortable viewing angles.
  • Extras: Curved display, touchscreen, built-in speakers, USB hub.

Set a realistic budget and focus on features most important to you. Consider used monitors for better value.

  • Ensure all cables and accessories are included.

Connect to Your Computer:

  • Identify the compatible cable for your computer and monitor (often HDMI or DisplayPort).
  • Connect the video cable from the monitor to your computer’s graphics card port (not the motherboard).
  • If using a separate power cable for the monitor, connect it to a power outlet.

Power On and Adjust Settings:

  • Turn on both the monitor and your computer.
  • The monitor should automatically detect the input signal.
  • If not, manually select the correct input source using the monitor’s buttons or joystick.
  • Access the on-screen menu (OSD) using the monitor’s controls.
  • Adjust display settings like brightness, contrast, color temperature, and resolution to your preference.

Optimize for Usage:

  • For gaming: Enable features like G-Sync/FreeSync (if compatible) and adjust refresh rate and response time.
  • For professional work: Calibrate the monitor for accurate color representation using professional software or hardware calibrators.
  • For ergonomics: Adjust the stand height and tilt for optimal viewing comfort.

If you encounter any difficulties during setup, refer to your monitor’s manual, online resources, or contact the manufacturer’s customer support for assistance.


What is the ideal size for a computer monitor?

Selecting the ideal size depends on your specific needs. For general use, a 24-27 inch monitor is recommended. However, gamers may prefer larger displays for an immersive experience.

How often should I calibrate my monitor?

Calibrating your monitor annually is generally sufficient for most users. However, professionals in graphic design or photography may benefit from more frequent calibrations to ensure color accuracy.

Can I use a TV as a computer monitor?

While possible, using a TV as a computer monitor may result in suboptimal performance due to differences in resolution and refresh rate. It’s advisable to choose a dedicated computer monitor for optimal results.

What is the significance of a high refresh rate in gaming monitors?

A higher refresh rate, such as 144Hz or 240Hz, provides smoother motion and reduces motion blur in fast-paced games. This can enhance the overall gaming experience and provide a competitive edge.

Are curved monitors better than flat monitors?

The preference for curved or flat monitors is subjective. Curved monitors can offer a more immersive viewing experience, especially for gaming, while flat monitors are preferred for professional tasks that require precise image representation.

How do I prevent eye strain when using a computer monitor for extended periods?

To reduce eye strain, ensure proper ergonomics, take regular breaks, and use features like blue light filters. Adjust the monitor’s height and angle to minimize glare and reflections.
