Task Manager, the quickest way
- Press Ctrl, Shift and Esc together to open Task Manager.
- If it opens as a small window, click More details at the bottom.
- Open the Performance tab and pick GPU from the list on the left.
- The name of the card is in the top right corner of that panel. The memory it has is under the graphs, labelled dedicated GPU memory.
If the PC has two graphics devices you will see GPU 0 and GPU 1. Go by the names. The numbers do not tell you which one is built in.
Device Manager
- Right-click the Start button and choose Device Manager.
- Click the arrow next to Display adapters.
- Every line is a graphics device. Two lines usually mean a laptop with built-in graphics and a separate chip.
The DirectX Diagnostic Tool
- Press the Windows key and R together, type dxdiag and press Enter. If it asks about checking drivers, say yes.
- Open the Display tab. A PC with two graphics devices has a tab for each.
- The name, the maker and the display memory are listed on the left.
Settings
Open Settings, then System, then Display. Scroll down to Advanced display and choose Display adapter properties. The name of the card is at the top of the window that opens. On Windows 10 the same screen is called Advanced display settings.
PowerShell
Open PowerShell and paste this line:
Get-CimInstance Win32_VideoController | Select-Object Name, DriverVersion
It lists every graphics device and its driver version. If you add AdapterRAM to the list, do not trust it for cards with more than 4 GB, because Windows reports that figure in a way that stops at 4 GB. Task Manager shows the real amount.
If you only see Microsoft Basic Display Adapter
That means Windows has no proper driver for your graphics hardware. Download the driver from the maker of the card (NVIDIA, AMD or Intel) or from your laptop's maker and install it. The real model name appears after that.
