How To Test A New Monitor

How To Test A New Monitor? Testing a new monitor is an essential step in ensuring that you get the best performance out of your investment. A new monitor offers improved display quality, better resolution, and faster refresh rates, but you need to ensure that it meets your specific requirements before making a purchase. Whether you are a gamer, a professional designer, or just someone who wants a better viewing experience, testing a new monitor is an easy and effective way to determine whether it is the right fit for your needs. In this guide, we will explore some of the key steps you can take to test a new monitor and make sure that it delivers the performance and features you need.

Checking The Display Quality

Checking the Display Quality of a new monitor is one of the most important steps in the testing process. Here are some things to look out for:

  1. Display Resolution: Ensure that the monitor is set to its native resolution and that all content is displayed clearly and crisply.
  2. Contrast Ratio: Check that the contrast ratio is satisfactory and that blacks appear deep and whites are bright.
  3. Brightness: Verify the monitor’s brightness settings.
  4. Color Saturation: Ensure that the monitor displays colors accurately and vividly.
  5. Pixel Density: Check that the pixel density is high enough to provide a sharp and detailed image.

Testing For Dead Pixels

One of the common issues that can occur with a new monitor is the presence of dead pixels. Dead pixels are pixels that do not light up, resulting in a black or discolored spot on the screen. Here are some steps to test for dead pixels:

  • Open a solid-colored background, such as black, white, or red.
  • Inspect the monitor carefully for any spots or areas that are discolored or appear as black spots.
  • If you notice any dead pixels, mark them with a small piece of tape and contact the manufacturer to inquire about a replacement. Many manufacturers offer a warranty for dead pixels within a certain period.
  • It is important to note that some monitors may have a few dead pixels that are not noticeable during regular use. However, if the dead pixels are clustered in a particular area or are numerous, it can impact your viewing experience and warrant a replacement.

Verifying The Refresh Rate

The refresh rate is the number of times per second that a monitor updates its display. It is measured in hertz (Hz). A higher refresh rate can result in smoother motion and reduce eye strain. Here are some steps to verify the refresh rate of a new monitor:

  1. Open the display settings on your computer and navigate to the display section.
  1. Check the refresh rate of your monitor and ensure that it matches the advertised rate.
  1. If your monitor has a variable refresh rate, enable it and check that it is functioning correctly. Variable refresh rates can help to reduce screen tearing and stuttering during gameplay or video playback.
  1. Test the refresh rate by playing a game or video with fast-paced motion to see if the motion appears smooth and fluid.

If the refresh rate does not match the advertised rate, it may be a result of incorrect settings or a faulty monitor. Contact the manufacturer for assistance.

Measuring The Input Lag

Input lag is the delay between the time a command is entered and the time it appears on the screen. It can be a significant factor in gaming and other applications where fast reaction times are important. Here are some steps to measure the input lag of a new monitor:

  • Download an input lag test tool or website that measures input lag.
  • Connect your computer to the monitor using a high-quality display cable to minimize any potential lag caused by the connection.
  • Open the input lag test tool or website and follow the instructions to measure the input lag.
  • Record the results and compare them to the advertised input lag of the monitor.
  • If the input lag is higher than advertised or if you notice any delay in response time during use, consider adjusting the settings or contacting the manufacturer for assistance.

It is important to note that input lag can vary depending on the type of game or application you are using, so be sure to test the monitor with the specific programs you intend to use.

Checking For Compatibility With Your System

Before purchasing a new monitor, it’s important to ensure that it is compatible with your computer or gaming system. Here are some steps to check for compatibility:

  1. Check the connector ports on your computer or gaming system to see what types of cables it supports (e.g. HDMI, DisplayPort, VGA, DVI).
  1. Make sure the monitor has compatible input ports to connect to your computer or gaming system.
  2. Check the minimum requirements of the monitor, including the resolution, refresh rate, and graphics card compatibility, to make sure it is supported by your computer or gaming system.
  1. Check if the operating system supports the monitor and if any additional drivers or software are required.
  1. If you are using a gaming system, check if the monitor is compatible with features like G-Sync or FreeSync.

Evaluating The Color Accuracy And Examining The Viewing Angle

Evaluating the color accuracy and examining the viewing angle of a new monitor are important steps to ensure that you get the best possible image quality. Here are some steps to follow:

  1. Open an image or video that has a wide range of colors and examine the colors on the screen. Make sure they are accurate and true to life.
  1. Look for any color banding or gradation issues. Color banding occurs when a monitor cannot display a wide range of colors and instead shows a distinct line between colors.
  1. Test the monitor from different viewing angles to see if the image quality is consistent across the screen. Some monitors may have a narrow viewing angle, which can result in color distortion or reduced brightness from certain angles.
  1. Adjust the monitor settings, including brightness, contrast, and color temperature, to optimize the image quality for your preferences and lighting conditions.
  1. If you plan to use the monitor for color-critical work, such as photo or video editing, consider calibrating the monitor using a colorimeter or seeking professional calibration services to ensure the most accurate color reproduction.

Testing For Backlight Bleed

Backlight bleed is a common issue with LCD monitors, where light from the backlight leaks through the edges of the screen, resulting in areas of uneven brightness. Here are some steps to test for backlight bleed:

  1. Turn off all the lights in the room and set the monitor to display a completely black screen.
  1. Inspect the screen carefully for any areas of uneven brightness, particularly around the edges of the screen.
  1. If you notice any backlight bleed, adjust the monitor’s position or tilt angle to see if it improves. In some cases, the issue may be more noticeable when viewing the screen from certain angles.
  1. If the backlight bleed is severe, consider contacting the manufacturer to inquire about a replacement or repair.

Assessing The Ergonomics

Assessing the ergonomics of a new monitor is important for ensuring that it provides a comfortable and healthy viewing experience. Here are some steps to assess the ergonomics of a new monitor:

  • Check if the monitor has adjustable height, tilt, and swivel features to optimize the viewing angle and reduce strain on the neck and eyes.
  • Check if the monitor has an anti-glare coating or a matte finish to reduce reflections and glare, which can cause eye strain and discomfort.
  • If you plan to use the monitor for extended periods, consider investing in an ergonomic monitor stand or a specialized monitor arm to further optimize the viewing angle and reduce strain on the neck and shoulders.


Testing a new monitor is an important step to ensure that you get the best possible image quality and a comfortable viewing experience. By following the steps outlined in this article, you can evaluate the display quality, test for dead pixels, verify the refresh rate and input lag, check for compatibility with your system, evaluate the color accuracy and viewing angle, test for backlight bleed, and assess the ergonomics of the monitor. 

By taking the time to thoroughly test a new monitor, you can ensure that it meets your requirements and provides an optimal viewing experience, whether you use it for work or entertainment.

Additionally, it is important to consider your individual needs when testing a new monitor. For example, if you plan to use the monitor for gaming, you may prioritize features like a high refresh rate and low input lag. On the other hand, if you plan to use the monitor for photo or video editing, you may prioritize features like accurate color reproduction and a wide viewing angle.

Therefore, it is important to evaluate the monitor based on your personal preferences and requirements, rather than relying solely on technical specifications or reviews.
