On Windows 11, the quickest way to identify your graphics card and see whether it is doing work is Task Manager: press Ctrl+Shift+Esc, select Performance, and choose each GPU entry. The model name appears at the top and live usage graphs appear below it. You can also open Settings > System > Display > Advanced display for a settings-based identification. These answer two related but different questions: which GPUs are installed, and which one is active for a particular program.
First decide what “using” means
“Which graphics card does my PC have?” normally means identifying the GPU or GPUs installed in Windows. “Which graphics card is my PC using?” can instead mean finding the GPU currently handling graphics work for a game, browser, video editor, or another application. A computer can have more than one GPU, so the installed list and the GPU doing work at a particular moment are not necessarily the same thing.
A GPU is the processor responsible for graphics-related work. Integrated graphics are built into the processor or platform and use shared system resources; a desktop discrete GPU is a separate card plugged into the motherboard. Laptops commonly include both types. Microsoft explains these roles in its overview of graphics processing units.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Seeing a GPU listed proves that Windows can identify that device. It does not, by itself, prove that a particular app is rendering on it right now. To answer the activity question, watch the usage graphs for each GPU while the program is open and performing the task you care about.

Use Task Manager for the model and live activity
Task Manager is the best first choice when you want both the card’s name and evidence of current activity. Microsoft’s Windows 11 guidance points to Task Manager > Performance > GPU for this purpose.
- Press Ctrl+Shift+Esc. This opens Task Manager without requiring a Start-menu search.
- If Task Manager opens in its compact view, select More details so the navigation sections are visible.
- Select Performance in the left navigation.
- Choose the first entry labeled GPU, such as GPU 0. The exact numbering and labels depend on the devices Windows detects.
- Read the model name shown at the top of the page. The page also includes utilization graphs and other performance readings for that adapter.
- If more than one GPU entry is present, select each one and record its model name separately. Leave the relevant program running and observe which graph changes when it draws a scene, plays a video, exports media, or performs another graphics-heavy action.
The model name is the identification you need for driver checks, application settings, or a hardware inventory. The graphs provide a time-based view rather than a permanent assignment. A short task may create only a brief spike, so watch while the operation is actually happening instead of relying on a graph after the work has finished.
How to read several GPU entries
Task Manager can list multiple adapters independently and provide performance data for each. Do not assume that GPU 0 is always integrated graphics or that the highest-numbered entry is always the discrete card. Windows assigns the numbers it displays; the model name is the reliable way to tell the devices apart.
For example, a laptop might show an integrated adapter and a separate discrete adapter. Both can be installed and visible even when a particular application is using only one. Select every entry before drawing a conclusion, especially when a game appears to have low activity on the first GPU.
Check a particular app while it runs
- Open Task Manager and select Performance.
- Keep the GPU pages visible, or switch between the entries if the window is narrow.
- Start the application you want to investigate.
- Perform a repeatable action that should involve graphics, such as opening a 3D scene, scrolling a complex page, playing a video, or beginning an export.
- Watch each GPU’s utilization graph during that action. A graph that rises at the same time as the work is useful evidence that the adapter is handling graphics activity.
- Repeat the observation with the other GPU entries. If both show activity, the system may be dividing work between them or using different engines; the list alone cannot tell you that a single app is assigned exclusively to one device.
This method is an observation of current work, not a guarantee about every frame or every moment. A workload can finish between graph updates, and a program can use different graphics paths for different tasks.

Identify the GPU through Windows 11 Settings
Settings provides a straightforward way to find display hardware without opening a diagnostic utility. The documented Windows 11 route is:
- Open Settings from the Start menu or with Windows+I.
- Select System.
- Select Display.
- Scroll to and open Advanced display.
- Read the GPU or display information shown for the selected display.
The exact wording and arrangement can change between Windows releases, and a multi-display system may provide a display selector. Check the information for each display if you are trying to understand a laptop dock or several monitors. Advanced display is useful for a quick Windows overview, but it is not the best place to watch per-GPU activity; use Task Manager’s Performance section for live graphs. Microsoft documents this Windows 11 route in its GPU-checking guide.
Use Device Manager to see installed display adapters
Device Manager is a fallback when you need a list of devices Windows has detected, rather than a live usage reading.
- Open the Start menu and search for Device Manager.
- Open the result.
- Expand Display adapters.
- Read each device name in the expanded list.
Each listed adapter is an installed display device recognized by Windows. This is useful when Task Manager’s performance view is unavailable or when you are checking whether more than one adapter exists. Microsoft’s Using Device Manager documentation describes how the utility displays information about devices.
Device Manager does not show which GPU a particular program is using at this moment. Treat it as an installed-device inventory, then switch to Task Manager if your question is about active rendering or workload.

Use DxDiag when you need a diagnostic report
DirectX Diagnostic Tool (DxDiag) is useful when you need to capture system information for support or keep a report alongside other troubleshooting details. Its screens can vary by Windows version, so use it for the information it actually presents rather than assuming every graphics field is identical on every PC.
Free tools Windows power users keep installed
One-click scans. No signup required.
- Search Windows for dxdiag.
- Open DirectX Diagnostic Tool from the results. Approve the prompt if Windows asks whether it should check digitally signed drivers.
- Review the available information. The Microsoft support instructions specifically cover the System tab and the DirectX version shown there; other tabs and display fields can differ by system.
- Select Save All Information to export a text report when a technician, support forum, or IT department asks for diagnostic details.
- Open the saved report and share only the information appropriate for the support request, since it can include broader system details than the GPU model alone.
Microsoft’s instructions for opening DxDiag and saving a report are available in Which version of DirectX is on your PC?. DxDiag complements Task Manager and Device Manager; it is not a replacement for watching live GPU usage.
Understand integrated and discrete GPUs
Knowing why two adapters appear prevents a common misreading. Integrated graphics are part of the processor or platform, while a discrete desktop GPU is a separate expansion card. Laptops often combine both so the system can use one adapter for routine display work and another for demanding graphics tasks. The presence of both does not mean that both are rendering every application at the same time.
| What you see | What it establishes | What it does not establish |
|---|---|---|
| One GPU in Task Manager | Windows currently exposes one GPU performance entry. | That every application uses the same rendering path for every task. |
| Two or more GPU entries | Windows has detected multiple graphics adapters and can show separate performance data. | That GPU 0 is integrated, that the last entry is discrete, or that a named app is assigned to only one adapter. |
| A model in Device Manager | The adapter is listed among installed display devices. | That the adapter is doing work right now. |
| Activity on a Task Manager graph while an app runs | The adapter is showing graphics-related work during the observed period. | That it handled every operation or every frame produced by the app. |
Use the model names and the timing of the graphs together. Avoid labeling an adapter from its number alone, because the numbering is not a reliable description of its hardware type.
A practical method for finding the GPU an app is using
If your concern is a particular game or creative application, use a controlled observation rather than simply reading the installed list.

- Perform the same visible operation several times, such as loading a level, rotating a 3D view, or starting a render.
- Watch for utilization changes on every GPU page during the operation. Record the adapter whose graph responds consistently with the work.
- Stop the operation and observe whether the activity falls. Repeat once more if the first action was too brief to produce a clear change.
A sustained or repeatable rise is stronger evidence than a single momentary spike. If both adapters move, the application or Windows may be using more than one graphics path. If neither graph visibly changes, try a longer or more demanding operation; a quick task may complete before you can observe it. The procedure tells you what was active during the test, not a permanent rule for all programs.
Which Windows method should you use?
| Method | Best for | What to look for | Main limitation |
|---|---|---|---|
| Task Manager > Performance > GPU | Fast identification plus live activity | Model name at the top of each GPU page and changing usage graphs | Does not, from the list alone, prove an app’s exclusive GPU assignment |
| Settings > System > Display > Advanced display | A quick Windows 11 settings overview | GPU information associated with the selected display | Not intended as a live multi-GPU workload monitor |
| Device Manager > Display adapters | Installed-device inventory | Every adapter Windows lists under Display adapters | Does not report current per-app usage |
| DxDiag | Support and diagnostic documentation | Available system and DirectX information, plus a saved report | Fields and tabs can vary by Windows version and system |
For most readers, start with Task Manager. Move to Settings when you only need a quick display-related identification, Device Manager when you need the installed list, and DxDiag when someone needs a reproducible diagnostic report.

Only one GPU appears, but you expected two
Check Device Manager > Display adapters to see whether Windows lists another adapter there. Then compare the model names rather than assuming that a missing entry is hidden behind a GPU number. If the second device is not listed in either location, DxDiag’s saved report can give support staff additional system context. The built-in tools can identify what Windows currently detects; they cannot establish hardware that Windows does not expose.
The GPU name is visible, but usage stays near zero
Make sure the application is open and performing a graphics operation while you watch the graph. A short action can finish before the graph visibly changes, so repeat it or choose a longer workload. Check every GPU entry, because a laptop may be doing the work on a different adapter than the first one you opened. Do not infer inactivity solely from looking at GPU 0.

Record the exact model name shown in Task Manager, Settings, or Device Manager and compare it across the tools. A PC with integrated and discrete graphics can legitimately show two different names. If the names disagree between tools, save a DxDiag report and provide the exact Windows screens and model names to support; avoid replacing a device based only on its numerical GPU label.

The Settings path is different
The documented Advanced display route applies to Windows 11, but interface labels can change with a release. Use Task Manager as the alternate built-in route, or search Settings for Advanced display. Device Manager remains a separate way to inspect the installed adapters when the Settings layout does not match these labels.
You need to send details to technical support
Capture the model name for every GPU entry, note which graph changed during the test, and save a DxDiag report with Save All Information. Include the Windows version and the application you tested if the support request asks for them. This gives the recipient both an installed-device inventory and an observation of activity without claiming that one GPU is always responsible for every task.
What to record for your own hardware inventory
A useful record contains more than a single “GPU” label. Write down:
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitches- The exact model name shown at the top of each Task Manager GPU page.
- How many GPU entries Task Manager displays.
- The adapter names listed under Device Manager’s Display adapters category.
- Which adapter’s graph changed during the application test, and what operation was running.
- Whether you checked a laptop display, an external monitor, or more than one display in Advanced display.
- The date of the observation, since hardware assignments and software behavior can change after updates or configuration changes.
This record distinguishes a stable hardware fact—the model Windows lists—from a time-specific observation about which adapter was active during one test.
The reliable decision path
Start in Task Manager when you need an answer now: it gives the model and lets you watch activity. Use Advanced display for a Windows 11 settings confirmation, Device Manager to enumerate installed adapters, and DxDiag when a supportable report is required. On systems with multiple GPUs, inspect each entry individually and judge activity while the target application is actually working; a listed GPU is not automatically the GPU rendering that application.
