Determining whether your Dell laptop is equipped with a touch screen can sometimes be less straightforward than you might think. While the presence of a touch screen might seem obvious, variations in model configurations and the subtle integration of touch technology can make it challenging to identify with certainty. This guide will provide you with a thorough and easy-to-follow set of methods to definitively answer the question: “Does my Dell laptop have a touch screen?”
Visual Inspection: The First Line of Defense
The most immediate way to check for a touch screen is through a careful visual inspection of your laptop’s display. Look closely at the screen’s surface. Touch screen models often have a glossy finish, which can make the display more reflective than a matte screen typically found on non-touch models. However, this isn’t a definitive indicator, as some non-touch screens may also have a glossy coating.
Next, examine the bezel surrounding the screen. Touch screen laptops frequently have a completely flat screen that extends to the very edge of the bezel. Non-touch screen models often have a slightly recessed screen, with a small lip or raised frame around the display. This difference is due to the overlay needed for touch functionality.
Pay particular attention to the presence of a protective glass layer. Touch screen laptops typically have a layer of glass covering the LCD panel. This glass layer provides protection and enables the touch sensing capabilities. You can usually notice this by carefully observing the edge of the screen where it meets the bezel.
Checking System Information: Software-Based Identification
If the visual inspection doesn’t provide a clear answer, you can delve into your laptop’s system information to determine if touch capabilities are enabled and recognized by the operating system. The steps for doing this vary slightly depending on whether you’re running Windows or another operating system.
Windows: The Built-in Touch Indicator

- Press the Windows key + R to open the Run dialog box.
- Type “msinfo32” (without the quotes) and press Enter. This will open the System Information window.
- In the System Information window, look for the “System Summary” section on the left-hand side.
- In the right-hand pane, scroll down until you find the “Input” section. Look for an entry that specifically mentions “Touch” or “Digitizer.” If you see an entry that says “Input: Pen and Touch,” it confirms that your laptop has a touch screen. The description may also specify the type of touch technology used, such as multi-touch. If no such entry exists, your laptop likely does not have a touch screen.
Another method to check for touch screen capabilities in Windows involves using the Device Manager.
- Right-click on the Windows Start button and select “Device Manager.”
- In the Device Manager window, expand the “Human Interface Devices” section.
- Look for devices listed under this section that include terms such as “Touchscreen,” “HID-compliant touch screen,” or “Digitizer.” The presence of these devices indicates that Windows recognizes and supports a touch screen. If you don’t see any such devices, it’s unlikely that your laptop has a touch screen. Remember to look carefully! Sometimes the name can be slightly different.
- If you find a device that appears to be related to touch, right-click on it and select “Properties.” In the Properties window, check the “Device status” to ensure that the device is working properly and is enabled.
Linux: Utilizing Command-Line Tools
If your Dell laptop runs on a Linux distribution, you can use command-line tools to identify touch screen capabilities.
