Beginner’s Guide to 40-Inch Monitors

What Are 40-Inch Monitors?

A 40-inch monitor is a display device that hooks up to your laptop or computer via a display cable such as a DisplayPort cable or an HDMI cable. Once connected to your computer, your monitor displays information from your computer so you can see the applications, video games, or internet browser you’re using. This is similar to how the highly-rated gaming monitors for Nintendo Switch work.

Most computer monitors offer the same form factor, but there are a variety of different types of monitors to consider. In general, though, most 40-inch displays are either LCD or LED monitors, and they most commonly use an IPS panel technology. Which, you’ll want an IPS monitor, since they’re perfect for color accuracy and are considered some of the best monitors for graphic design.

40-Inch Monitors vs. Traditional Monitors

If you were to compare a 40-inch monitor to a traditional monitor in terms of general form and function, you likely wouldn’t be able to tell much of a difference. A 40-inch monitor doesn’t operate in ways different than a standard office computer monitor, although, you might see the difference in size compared to a high-end 38-inch monitor. But, you’ll have to look closely.

There is one major difference between 40-inch monitors and traditional computer monitors, though, and that comes into play when you consider the aspect ratio of the display. Most flatscreen monitors offer a 16:9 aspect ratio, which is considered optimal on many of the leading widescreen monitors. Most 40-inch monitors have a 21:9 ultrawide aspect ratio.

With a 21:9 aspect ratio, you get a lot more horizontal space than you do with a standard 16:9 aspect ratio. With larger displays like these, you’ll be able to multitask more easily since you can place full-size windows side-by-side. This feature alone makes 40-inch displays into the perfect professional monitors.

It’s also worth noting that many ultrawide monitors feature a curved screen. When you have an ultrawide configuration, it can be difficult to see everything on the display without turning your head all over the place. A curved screen eliminates this problem, so it’s a good idea to peruse the hottest curved gaming monitors now available.

How 40-Inch Monitors Work

Simply put, 40-inch monitors work by plugging into a wall outlet for power and then by plugging into your computer to receive the information. It’s practically the same process for any monitor, including the Dell Computer Ultrasharp U2415.

On the technical side of things, a 40-inch monitor generally uses LCD technology, which stands for liquid crystal display. LCD monitors feature two panes of glass with liquid crystals between them that activate and react to backlighting.

Ultrawide monitors usually use cold cathode fluorescent lamps (CCFLs) or light-emitting diodes (LEDs) for backlighting. The top 40-inch monitors usually use LED lighting since they offer a wider brightness range and longer lifespan.

Do You Really Need a 40-Inch Monitor?

40-inch ultrawide monitors aren’t for everyone, but they make for excellent professional displays. If you want to more easily multitask or create a more immersive gaming experience, then a 40-inch ultrawide monitor is a perfect choice for you.

Is a 40-Inch Monitor Worth Buying?

  • You Need Better Multitasking Capabilities: 40-inch monitors are perfect for multitasking because they offer a lot of screen real estate, which allows you to keep applications side-by-side. Plus, these monitors also offer screen-splitting software built-in that allows you to partition off your screen as if you were using a multi-monitor setup.
  • You Prefer an Immersive Gaming Experience: 40-inch monitors often provide curved screens, which in turn lead to a more immersive gaming experience. The 21:9 aspect ratio allows you to see more of your games and the curved display minimizes the amount you have to turn your head to see everything going on. Plus, ultrawide monitors usually feature fast response times, high refresh rates, and excellent color accuracy.
  • You Want the Best Technology Available: Most ultrawide monitors in the 40-inch size range offer top-of-the-line technology. If you love using the most advanced technology available, then a 40-inch monitor is an excellent choice for you.

Why a 40-Inch Monitor May Not Be For You

  • You Have a Compact Desk Space: 40-inch monitors take up a ton of space. If you don’t have a ton of room on your desk or in your office, then a larger display like a 40-inch monitor may not be the best for you.
  • You’re Looking for a Cheap Monitor: If you’re looking for a cheap monitor, you’ll have a hard time in the 40-inch size category. Since ultrawide monitors use advanced technology, they are often the most expensive options on the market today.
  • You’re a Video Editor or Artist: 40-inch monitors, especially curved monitors, can have minor difficulties with backlighting and color accuracy. This can cause some hiccups when it comes to content creation for video editors and artists.

How Long Will a 40-Inch Monitor Last?

Most 40-inch monitors are either LCD or LED monitors, meaning you’ll get the most lifespan out of them. Most technology pros, like those at TechiExpert, agree that LCD monitors will last for 30,000 to 60,000 hours and that LED monitors will last for 80,000 to 120,000 hours.

Of course, the actual lifespan of your ultrawide monitor depends on how well you treat it. For example, if you don’t activate any kind of power-saving features, you’ll likely lessen the lifespan of your monitor. The same goes for keeping your monitor in a dusty and dirty environment.

How to Choose the Best 40-Inch Monitor

Before you press the buy button or even before you start shopping for the best ultrawide monitor, you need to determine what features are the most important for your specific needs.

40-Inch Monitor Key Factors to Consider

Read through the following questions to learn more about the key factors you should consider when shopping for a new 40-inch monitor.

1. What is the best panel technology for your needs?

40-inch monitors usually stick to one of two panel types in their display technology: VA or IPS. These panel types simply describe the way the LCD technology works in your monitor. Here’s an in-depth explanation of both so you can determine which one works best for you:

  • VA Panel: Vertical alignment (VA) panels offer solid all-around performance and capabilities. They offer a better static contrast ratio for deep blacks than an IPS panel, but more narrow viewing angles. You can check out some of the best vertical monitors if you would love a larger viewing angle and better contrast.
  • IPS Panel: In-plane switching (IPS) panels are considered the gold standard for ultrawide monitors. This is because they feature better color reproduction, high contrast ratio, and wide viewing angles. An IPS panel also tends to be more consistent in overall performance.

2. What screen resolution should you look for?

A computer monitor’s screen resolution is one of the most important qualities to consider, especially when it comes to visual quality and detailed images. Resolution is a measure of how many pixels are present in your ultrawide monitor, horizontally and vertically.

For ultrawide monitors like a 40-inch, the bare minimum resolution you should purchase is 2560×1080. However, this screen resolution can create some pixelated text and images thanks to the 21:9 aspect ratio.

For the best results, you should choose a 40-inch monitor with a 3440×1440 resolution. This is especially true if you’re a gamer or creative professional.

Some 40-inch monitors are starting to feature higher native resolutions than even 3440×1440. However, these are very expensive and uncommon at the time of publishing.

3. What do you need in terms of picture quality on your monitor?

One of the biggest selling points of a 40-inch monitor is the potential for excellent picture quality, depending on the specific model you purchase. Take a look at the following features so you know what to look for in terms of picture quality:

  • Color accuracy: Color accuracy refers to your computer monitor’s ability to reproduce accurate colors when compared to real-world color. While shopping for a new monitor, look for terminology such as wide color gamut. Monitors with a wide color gamut offer better out-of-box color accuracy.
  • Contrast ratio: When you see the term contrast ratio, it refers to the difference between light colors and dark colors on your monitor. 40-inch monitors tend to offer good contrast ratios, especially if you purchase an IPS display. A high static contrast ratio means you’ll get deeper blacks, which in turn creates a better overall picture.
  • Screen resolution: Higher screen resolution will always result in better picture quality, whether you are gaming, browsing the web, or working.

4. Do you need gaming-specific features on your monitor?

If you’re a gamer, then you recognize the need for gaming-specific features on your monitor, whether you’re planning on using it as a PC gaming monitor or a console gaming monitor. Of course, it will be difficult to game even on the best 22 inch monitor.

You can, however, consider these gaming features:

  • Response Time and Input Lag: Response time and input lag are commonly mistaken for one another, but they are actually two different aspects. Response time refers to the amount of time your computer takes to switch between colors. Input lag is the amount of time between you doing something on your keyboard or mouse and that action being mirrored on the display. A quick response time and low input lag are the best for gamers. Anything below 5ms is good for gaming, but if you’re into competitive gaming, you should look for a 1ms response time.
    • Refresh Rate: The refresh rate of a 40-inch monitor measures the number of times the display refreshes with a new image every second. This feature is measured in Hz.In general, the lowest refresh rate you’ll see in 40-inch monitors comes in the form of a 60Hz panel. However, the best 40-inch monitors offer at least a 100Hz refresh rate. For gaming, you should look for a 120Hz panel to get the best gaming and viewing experience.
      • Variable Refresh Rate: If you’re buying an ultrawide gaming monitor for competitive gaming, then you should get one with a variable refresh rate. Monitors with Nvidia G-Sync or AMD FreeSync sync directly to your computer’s compatible graphics card to create a seamless picture quality.

5. What kind of connectivity and adjustability do you need on your monitor?

Finally, consider how your 40-inch monitor will connect to your computer. There are a variety of connectivity options available on monitors today, but the specific connectivity ports on your monitor are important.

  • VGA Ports: In general, we recommend not using VGA ports on your 40-inch monitor. This is an older format that’s still commonly used in many professional monitors today, but it can only support up to a screen resolution of 2560×1600.
  • HDMI Ports: HDMI ports are quickly becoming the industry standard in a wide array of connectivity options thanks to their high-resolution capabilities and fast transfer speeds. Your 40-inch monitor should offer at least one HDMI port.
  • DisplayPort: If you want to buy a curved gaming monitor, then an option with a DisplayPort port is essential. DisplayPort supports up to 8K resolution, so you know you’ll be getting the best picture with these monitors.
  • USB Ports: Some 40-inch computer monitors also provide USB ports, including USB Type C ports. With both standard USB and USB-C ports, you’ll be able to use your monitor to connect to a variety of peripherals, including your keyboard and mouse.
  • Audio Input: If your monitor doesn’t offer internal speakers, you may want to connect some external speakers instead. Monitors with an audio input will allow various speakers to connect.

40-Inch Monitor FAQs

Are there any drawbacks to 40-inch monitors?

There are always features on larger displays that some people will consider to be drawbacks. The two main drawbacks to 40-inch monitors are their large footprint and expensive price range.

Are 4K 40-inch monitors worth it?

Yes, and in fact, we’d recommend purchasing a 4K monitor in this size category over anything less. If you choose to purchase a 40-inch ultrawide monitor with a resolution of less than 4K, you may experience some pixelation, especially with text.

Are ultrawide monitors better than standard computer monitors?

The answer to this question depends on the person and their needs. An ultrawide monitor is perfect for people who want to multitask or become more immersed in their games. Ultrawide monitors are also great for people who want the latest and greatest in display technology.

Do all video games support ultrawide monitors?

Most mainstream video games will support ultrawide monitors. You may run into some that don’t, but they are few and far between.
