The Dell Latitude 7490 is a popular business-class laptop known for its reliability, portability, and performance. A common question among potential buyers is whether it comes with a touch screen option. The answer, as with many laptop models, isn’t a simple yes or no. The Dell Latitude 7490 was offered with multiple display configurations, including both touch and non-touch options.
Understanding the Dell Latitude 7490 Display Options
The Dell Latitude 7490 provided a degree of customization at the point of purchase. This meant buyers could choose specifications to best suit their needs, including the type of display panel. This customization is why some Latitude 7490s have touch screens while others do not. To determine whether a specific Dell Latitude 7490 unit has a touch screen, you need to identify its specific configuration.
The base models of the Dell Latitude 7490 typically came with a non-touch display. These displays were often Full HD (1920×1080) resolution, providing sharp and clear visuals for everyday tasks.
The touch screen option was available as an upgrade. These touch-enabled models often featured the same Full HD resolution as their non-touch counterparts. However, the touch functionality added a layer of versatility, allowing users to interact with the laptop in a more intuitive way.
It’s crucial to understand that not all Dell Latitude 7490 laptops have a touch screen. You must verify the specific model’s specifications before purchasing if touch functionality is a requirement.
How to Determine if Your Dell Latitude 7490 Has a Touch Screen
If you already own a Dell Latitude 7490 and are unsure if it has a touch screen, there are several ways to check:
Physical Inspection
The most straightforward method is to simply try touching the screen. Gently tap or swipe on the display. If the laptop responds to your touch, it likely has a touch screen.
However, this method isn’t foolproof. A damaged or malfunctioning touch screen might not respond, even if the laptop is equipped with one.
Checking System Information
Windows provides information about the installed hardware. You can check the system information to see if a touch screen is detected.
Here’s how:
- Press the Windows key + R to open the Run dialog box.
- Type “msinfo32” and press Enter. This will open the System Information window.
- In the System Information window, navigate to Components > Input > Touch.
- If a touch screen is detected, you’ll see information about it listed here. If the “Touch” category is missing, your laptop likely does not have a touch screen.
Using Device Manager
Device Manager provides a comprehensive overview of all the hardware connected to your computer.
- Right-click on the Windows Start button and select “Device Manager.”
- In Device Manager, expand the “Human Interface Devices” category.
- Look for entries related to “Touchscreen,” “HID-compliant touch screen,” or similar devices.
- If you find any of these entries, your Dell Latitude 7490 likely has a touch screen. If not, it probably doesn’t.
Checking the Original Purchase Documentation or Dell’s Support Website
The original purchase documentation, such as the invoice or order confirmation, should specify the exact configuration of the laptop, including whether it has a touch screen.
Alternatively, you can visit the Dell Support website and enter your laptop’s service tag. This will provide access to the original configuration details and specifications. The service tag is usually located on a sticker on the bottom of the laptop. Dell’s website will list all the components that came with your device.

Consider your needs and priorities carefully before deciding whether a Dell Latitude 7490 with a touch screen is the right choice for you. Always verify the specific model’s features before committing to a purchase to ensure it meets your individual requirements.
Does the Dell Latitude 7490 always come with a touch screen?
No, the Dell Latitude 7490 does not always come with a touch screen. Dell offered the Latitude 7490 with a variety of display options to cater to different user needs and budgets. Some configurations feature a non-touch display, while others are equipped with a touch-enabled screen.
When purchasing a Dell Latitude 7490, it’s essential to carefully review the specifications of the specific model you’re considering. Look for explicit mention of “touch screen” or “touch display” in the product description. If unsure, contacting the seller or manufacturer directly to confirm the display type is advisable.
How can I tell if my Dell Latitude 7490 has a touch screen?
The simplest way to determine if your Dell Latitude 7490 has a touch screen is to physically touch the screen. If you can interact with the operating system and applications by touching the screen with your finger, then it is a touch screen. Try opening an application, scrolling through a web page, or tapping on icons.
Alternatively, you can check the system information within the operating system. In Windows, go to Device Manager and expand the “Human Interface Devices” category. If you see a “HID-compliant touch screen” entry, it confirms that your Latitude 7490 has a touch screen. If that entry is absent, it likely has a non-touch display.
What are the advantages of having a touch screen on the Dell Latitude 7490?
A touch screen on the Dell Latitude 7490 enhances user interaction and productivity by providing a more intuitive way to navigate and control applications. It allows for quick and easy access to features, making tasks like browsing, drawing, and note-taking more efficient. This is particularly beneficial for users who prefer a more hands-on approach or work with visual content.
Furthermore, a touch screen can be advantageous in scenarios where using a mouse or touchpad is inconvenient, such as during presentations or in confined spaces. It offers flexibility and adaptability, catering to various work styles and environments. Some users also appreciate the added convenience of performing simple actions directly on the screen.
What are the disadvantages of having a touch screen on the Dell Latitude 7490?
Touch screen displays can sometimes have slightly reduced battery life compared to non-touch versions, as the touch functionality requires additional power consumption. This difference, while typically not substantial, may be a factor for users prioritizing maximum battery longevity. Glare can also be more pronounced on some touch screen models, depending on the specific display coating.
Furthermore, touch screens are potentially more susceptible to smudges and fingerprints, requiring more frequent cleaning. The price of models with touch screen capability can also be higher than models without. For users who primarily rely on a keyboard and mouse, the added cost of a touch screen may not be justified.
What display resolutions were offered on the Dell Latitude 7490?
The Dell Latitude 7490 was offered with multiple display resolution options, allowing customers to choose the level of detail that best suited their needs. A common resolution was the standard 1366×768, providing a balance between image quality and battery efficiency. This was usually the most affordable option available.
However, higher resolution displays were also available, most notably a Full HD (1920×1080) option, offering sharper and more detailed visuals. The Full HD option was often preferred by professionals and users who frequently worked with graphics, video, or detailed documents. Some models also featured different panel types, such as IPS, affecting viewing angles and color accuracy.
Is the touch screen on the Dell Latitude 7490 active or passive?
The touch screen on the Dell Latitude 7490, when present, is typically an active touch screen, meaning it uses sensors to detect the precise location of your touch. This allows for more accurate and responsive interactions, enabling features like multi-touch gestures (pinch-to-zoom, two-finger scrolling). Active touch screens offer a higher level of precision compared to passive touch screens.
Passive touch screens, on the other hand, are less sensitive and usually only detect single-point touch. They are more commonly found on older or lower-end devices. The Dell Latitude 7490, being a business-class laptop, typically utilizes active touch technology to provide a more seamless and efficient user experience.
Can I add a touch screen to a Dell Latitude 7490 that originally didn’t have one?
Adding a touch screen to a Dell Latitude 7490 that originally came with a non-touch display is generally not a straightforward or recommended upgrade. It usually involves replacing the entire display assembly, including the screen and associated components. This requires specialized knowledge, tools, and access to compatible parts.
The cost of purchasing a new touch screen assembly and paying for professional installation can often be substantial, potentially exceeding the price difference between a non-touch and a touch screen model. Furthermore, compatibility issues may arise if the laptop’s internal circuitry and software are not designed to support a touch screen. A more practical solution might be to consider purchasing a different Dell Latitude 7490 model with a pre-installed touch screen or exploring external touch screen monitors.
