You’re trying to order a replacement power cable or update your drivers, and suddenly you hit a wall. The sticker on the back of your monitor has faded into oblivion, or maybe you bought this second-hand beast and never bothered to write down the brand. It’s a frustratingly common scenario that leaves many users staring at a glossy black panel, wondering what machine they’re actually looking at. But here’s the good news: you don’t need a magnifying glass or a screwdriver to solve this mystery.
Whether you are running Windows 10 or 11, there are several built-in tools that can reveal exactly what you’re working with. If you’ve ever searched for how to check monitor model on Windows, you’ve likely hit a dead end or found outdated advice. In this guide, I’ll walk you through five distinct methods, ranging from the simplest GUI clicks to some advanced command-line tricks. We’ll also tackle why your Device Manager might be hiding the real name behind a generic label and how to dig deeper. Let’s get your monitor identified once and for all.
Method 1: How to Check Monitor Model on Windows Using Settings (Easiest)
This is the method I recommend to 90% of the people I help. It’s straightforward, it’s native to the OS, and it doesn’t require any technical know-how. Microsoft has actually made this easier in Windows 11 compared to the tortuous paths of Windows 10, but both get the job done.
Via System Settings (Windows 10 & 11)
The journey begins in the Settings app. On both Windows 10 and 11, you want to navigate to Settings > System > Display. Once you’re there, look for a link labeled "Advanced display" (or "Advanced display settings" in older builds). This is where Windows aggregates all the handshake data between your GPU and the screen.
If you have a dual-monitor setup, don’t panic if you only see one set of details. There will be a drop-down menu at the top of the page—usually labeled "Select a display to view or change its settings." Click that, and you can toggle between Monitor 1 and Monitor 2 to see their individual specs.
[Screenshot Placeholder: Windows 11 Advanced Display path showing Settings > System > Display > Advanced display]
Note: In Windows 10, this option is often tucked slightly differently under "Display settings" as "Advanced display list" on the right rail, but the logic remains identical.
Interpreting the Display Information Panel
Once you’re on the Advanced Display page, look for the "Display info" section. Here, you’ll see a handful of metrics. Your primary target is the "Model" field, which should ideally list the specific product name (e.g., "Dell UltraSharp U2720Q").
However, there’s a nuance here that trips people up. You’ll often see two sets of resolution and refresh rate data: Desktop mode and Active signal mode. Desktop mode is what you’ve configured Windows to use, while Active signal mode is what the monitor is actually receiving right now. If you’re troubleshooting a flickering screen or a dropped refresh rate, comparing these two can tell you if your cable is the bottleneck.
You might also spot details like Bit depth and Color format. Bit depth (usually 8-bit or 10-bit) indicates how many colors the panel can display simultaneously. Higher bit depths mean smoother gradients and less "banding" in skies or shadows. Color format (like RGB or YCbCr) tells you how color data is being transmitted over your HDMI or DisplayPort cable.
Additionally, if your monitor supports HDR, you’ll see an "HDR" status indicator. In modern Windows versions, you can also check for Dynamic Refresh Rate (DRR) status. If the "Dynamic" toggle is present, your monitor can shift refresh rates on the fly to save power or boost responsiveness, a feature common in newer OLED and high-end IPS panels.
Method 2: Find Monitor Model Number in Device Manager
Sometimes the Settings app shows "Generic PnP Monitor" instead of the actual brand name. This is annoying, but Device Manager is your next best friend. It digs a layer deeper into the hardware IDs that Windows uses to talk to your display.
Step-by-Step Navigation to Monitors List
To get here, right-click the Start button and select Device Manager. Alternatively, you can press Win + X and pick it from the menu. In the device list, scroll down to the Monitors section and click the arrow to expand it.
This is where the distinction between "Generic PnP Monitor" and a specific name matters. If you see "Generic PnP Monitor," it means Windows has successfully established a basic communication channel (Plug and Play) but lacks the specific driver or EDID data to identify the manufacturer. In most cases, this is harmless—the monitor works fine—but it makes finding the exact model number harder.
Why does this happen? Often, it’s due to a missing or outdated monitor driver, or sometimes the cable connection is marginal. If you’re using an HDMI adapter or a cheap USB-C dongle, Windows may default to the generic identifier because the Extended Display Identification Data (EDID) isn't passing through cleanly.

Extracting Hardware IDs for Precise Identification
Even if the name says "Generic," the hardware ID is usually a treasure trove. Right-click the monitor entry and select Properties. Switch to the Details tab. From the "Property" dropdown menu at the top, select Hardware Ids.
You’ll likely see a few strings. Look for one that starts with MONITOR\ followed by a code. For example, MONITOR\DEL4022 or MONITOR\SAM.... The part after the backslash is your clue. The first three letters often represent the manufacturer code (like DEL for Dell, SAM for Samsung), and the numbers following are the product code.
I’ve found that copying these Hardware IDs and pasting them into Google is often the fastest way to find the exact manual or product page. Search for "MONITOR\DEL4022" and you’ll likely land on a Dell support forum or a spec sheet that confirms your monitor is indeed the Ultrasharp 24" model. This method bypasses the generic label entirely and gets you the truth.
Method 3: Get Monitor Specs from Command Prompt & PowerShell
For those who prefer the keyboard over the mouse, or who need to script this information for IT inventory purposes, the command line is surprisingly powerful. While WMIC is fading into obscurity, PowerShell still holds the keys to the kingdom.
Using WMIC Command
You might encounter old guides suggesting you use wmic desktopmonitor get name, screenheight, screenwidth. It’s worth knowing about because it can work, but it’s inconsistent. Open Command Prompt as Administrator and run that command.
The problem? In Windows 10 and 11, WMIC often returns blank results for the monitor name or fails to recognize secondary monitors correctly. It’s a legacy tool that Microsoft has largely moved away from. If you run it and get a clean result, great. If you get blank spaces, don’t waste time debugging it—move on to PowerShell.
Using PowerShell with Get-CimInstance
PowerShell is the modern standard for WMI (Windows Management Instrumentation) queries. Open PowerShell and run the following command:
Get-CimInstance -Namespace root/cimv2 -Query 'SELECT * FROM Win32_DesktopMonitor'
This query pulls data from the Win32_DesktopMonitor class. You’ll get properties like Name, ScreenHeight, and ScreenWidth. However, the Name property here can sometimes be vague.
For richer data, specifically the manufacturer and serial number encoded in the monitor's firmware, you need to query a different namespace: root\wmi. A more robust command looks like this:
Get-CimInstance -Namespace root\wmi -ClassName WmiMonitorID | Select-Object UserFriendlyName, SerialNumberID, ManufacturerName
Note that these outputs are arrays of ASCII bytes. To make them readable, you’d ideally pipe them through an encoding converter, but for a quick check, the raw output might show numbers. A cleaner approach, which I use when auditing systems, is a simple script block that converts those byte arrays to strings:
Get-CimInstance -Namespace root\wmi -ClassName WmiMonitorID | ForEach-Object {
[PSCustomObject]@{
Manufacturer = ([System.Text.Encoding]::ASCII.GetString($_.ManufacturerName)).Trim()
Model = ([System.Text.Encoding]::ASCII.GetString($_.UserFriendlyName)).Trim()
Serial = ([System.Text.Encoding]::ASCII.GetString($_.SerialNumberID)).Trim()
}
}
This gives you a clean table with the Manufacturer, Model, and Serial Number directly from the EDID data stored in the system memory. It’s precise, it’s fast, and it works even if the Settings app is being stubborn.
Method 4: Check Monitor Serial Number PC via EDID and Registry
If you need the serial number—perhaps for a warranty claim—and the physical sticker is gone, the data is likely still sitting in your Windows Registry or accessible via EDID reading tools. EDID, or Extended Display Identification Data, is a standard protocol that allows a display to tell a computer its capabilities and identity.
Reading EDID Data for Hidden Details
Every digital monitor has an EDID chip. When you plug it in, Windows reads this chip. While you can’t always "see" the chip physically, software can interpret the data it broadcasts.
Tools like HWiNFO64 or AIDA64 are industry standards for this. If you run a sensor read in HWiNFO, there is a specific section for "Monitor." It will parse the EDID block and give you the Manufacturer ID, Product Code, Serial Number, and even the Manufacturing Week and Year. This is invaluable if you bought a used monitor and want to verify its age or authenticity.

Why rely on third-party tools when Windows is right there? Sometimes the GUI methods fail to parse the EDID correctly, especially with older or obscure displays. These tools dig into the raw binary data that Windows might smooth over.
Detect Monitor Model via Registry Editor
For the technically inclined, the registry stores a copy of the monitor's descriptor. Press Win + R, type regedit, and navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\MONITOR
Here, you’ll see folders named after your connected monitors. If you expand one, you might find a Device Parameters key. Underneath, there’s often an EDID binary value. This is the raw EDID data.
While you won’t be able to read this with your naked eyes, you can export this binary file and use online EDID decoders to analyze it. Some advanced users also look under:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}
This is the display adapters class key. The subkeys (0000, 0001, etc.) correspond to your graphics cards, and within those, you might find monitor association data.
A word of caution: Do not modify anything in the Registry unless you know exactly what you’re doing. A wrong turn here can break your display configuration. Reading is fine; editing is dangerous.
Method 5: Physical Identification for Monitors That Won't Boot
What if the monitor won’t turn on? What if Windows can’t see it? Then we go old school. Physical inspection is the fallback when all software avenues are closed.
Locating Stickers on Dell, HP, Acer, and LG
Manufacturers don’t always put the sticker in the most obvious place. Over the years, I’ve peeled back countless stands to find the labels.
- Dell: Often hides the barcode sticker on the side of the stand neck or directly under the plastic bezel at the bottom. Some older models have it on the back, near the input ports.
- HP: Frequently places the label on the back panel, sometimes concealed if you have a wall mount attached. Check around the VESA mount area.
- Acer: tends to put it on the back, but on newer Predator or Swift lines, it might be under the hinge cover.
- LG: Usually on the back, lower right or left corner.
If you have a stand-mounted monitor, try rotating the stand fully. The model number is sometimes printed on the arm itself, not just the back panel.
Checking the Box or Receipt
It sounds obvious, but in the chaos of a new setup, the original box often gets tossed. If you have the box, the shipping label on the side almost always includes the model number and serial number in a clear, scannable format.
Similarly, if you bought it online, your order history on Amazon, Best Buy, or the manufacturer’s site will list the exact SKU you purchased. Using the serial number from the box or receipt, you can often check warranty status directly on the manufacturer’s support website without even turning the monitor on.
Understanding Your Monitor: IPS vs OLED and Other Specs
Once you’ve identified the model number, the next logical step is understanding what you’re actually looking at. Knowing whether your panel is IPS, VA, or OLED changes how you use the monitor, especially for color grading or gaming.
How to Tell if Your Monitor is IPS or OLED
Software won’t always tell you the panel type directly, but once you have the model number from Method 1 or 2, a quick search reveals everything. However, there are informal ways to guess.
OLED panels produce perfect blacks because each pixel emits its own light. If you display a black screen in a dark room and see faint glow or backlight bleed around the edges, it’s likely an IPS panel. OLEDs don’t have backlight bleed. Also, OLEDs often have a slightly "warmer" or more saturated default look compared to the sometimes cooler, clinical tone of IPS panels.
For a definitive answer, search your model number followed by "panel type" or "specifications." You’ll find reviews on sites like RTINGS or NotebookCheck that break down the exact panel model used (e.g., LG Display vs. Samsung Display). This helps you understand if your "1080p monitor" is actually a high-quality IPS with good color coverage or a budget TN panel with slow response times.
FAQ
How can I identify my monitors without opening the case?
The easiest way is via Windows Settings. Go to Settings > System > Display > Advanced display. The "Display info" section will list the monitor model. If that shows "Generic PnP Monitor," use Device Manager, expand the Monitors section, right-click the device, go to Properties > Details, and select Hardware Ids from the dropdown to find the specific model code.
How do I check my monitor specs using PowerShell?
Open PowerShell and run:
Get-CimInstance -Namespace root\wmi -ClassName WmiMonitorID
This returns the Manufacturer, Model, and Serial Number. For resolution and refresh rate, use:
Get-CimInstance -Namespace root\cimv2 -Query 'SELECT * FROM Win32_DesktopMonitor'
Where is the serial number located on a monitor?
Physically, it’s usually on a sticker on the back, under the stand, or on the side of the bezel. Digitally, you can find it in Windows Registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\MONITOR, or by using third-party tools like HWiNFO64 to read the EDID data directly from the monitor’s firmware.
What is the 3 type of monitor panel?
The three main types are IPS (In-Plane Switching), known for accurate colors and wide viewing angles; VA (Vertical Alignment), known for high contrast ratios and deep blacks; and TN (Twisted Nematic), known for fast response times but poorer color reproduction. OLED is a newer category where pixels emit their own light, offering perfect blacks and infinite contrast.
Conclusion
Identifying your monitor model doesn’t have to be a headache. Whether you’re dealing with a faded sticker or a second-hand purchase, Windows provides multiple layers of visibility. Start with Method 1 (Settings)—it solves the problem for most users in seconds. If that falls short, Device Manager and PowerShell offer the next tier of detail, digging into hardware IDs and EDID data that the basic GUI might hide. For the tech-savvy or the stubbornly uncooperative monitors, the Registry and physical inspection methods are reliable backups.
Remember, knowing your model number isn’t just about curiosity; it’s essential for warranty claims, driver updates, and ensuring your setup is running at its optimal resolution and refresh rate. I highly recommend saving this information in a secure note on your phone or cloud storage—it’s the first thing you’ll need if something goes wrong down the line.
