Modern computers often come with two types of graphics processors — integrated graphics (built into the CPU) and dedicated graphics cards (like NVIDIA or AMD). Integrated graphics are perfect for light tasks like web browsing or watching videos, but when you want top gaming performance, video editing, or 3D rendering, you’ll want your system to use the dedicated GPU.
However, sometimes your computer doesn’t automatically switch between the two or continues using the integrated graphics, which can slow down performance. In such cases, disabling integrated graphics manually can help.
In this comprehensive guide, we’ll walk you through how to disable integrated graphics using both Windows and BIOS/UEFI settings. We’ll also explore why you might want to disable them, potential risks, and tips for ensuring a smooth transition to dedicated graphics.
TL;DR
Disabling integrated graphics ensures your system uses the dedicated GPU for all graphical tasks, improving performance and reducing driver conflicts. You can disable integrated graphics via Device Manager in Windows or through your system’s BIOS/UEFI settings. Always confirm your monitor is connected to the dedicated GPU before making changes, and be cautious on laptops where integrated graphics help conserve battery life.
What Are Integrated Graphics?
Integrated graphics are GPUs built directly into your computer’s processor (CPU). They share the system’s RAM and power, which makes them energy-efficient but less powerful than dedicated graphics cards.
For example, Intel CPUs include Intel UHD or Iris Xe Graphics, while AMD CPUs may feature Radeon Vega Graphics. They’re ideal for everyday computing but not meant for high-end gaming or professional graphic workloads.
A dedicated GPU, on the other hand, has its own memory (VRAM) and processing power, designed specifically for demanding visual tasks. Disabling integrated graphics forces your system to use the dedicated card full-time for maximum performance.
Why Disable Integrated Graphics?
Disabling integrated graphics isn’t always necessary, but there are several compelling reasons to do so:
Boost Gaming or Rendering Performance:
Some systems split tasks between GPUs, but disabling the integrated one ensures your dedicated card handles everything.
Prevent Auto-Switching Issues:
Windows sometimes uses integrated graphics for certain apps even when a dedicated GPU is available. Disabling the integrated GPU fixes this.
Reduce Driver Conflicts:
Running both GPUs can occasionally cause crashes, black screens, or performance bugs, especially in older laptops or PCs.
Free Up Shared Memory:
Integrated graphics reserve part of your system’s RAM. Disabling them may slightly increase available memory for other tasks.
Thermal Management:
Reduces heat output by eliminating the use of the integrated GPU, which can help with cooling and battery life.
Multi-Monitor Setup:
Simplifies configuration when using multiple displays connected to a dedicated GPU.
However, disabling integrated graphics should only be done if you’re confident your dedicated GPU is functioning properly and compatible with your system.
Before You Disable Integrated Graphics
Before jumping into the steps, keep a few important things in mind:
- Make sure your dedicated GPU is installed properly.
Check that your graphics card is seated in the PCIe slot and connected to the monitor. - Install the latest GPU drivers.
Download and install drivers from NVIDIA, AMD, or your laptop manufacturer’s official website. - Connect your display to the GPU output port.
If your monitor cable is still plugged into the motherboard’s HDMI or DisplayPort, you won’t get any video output after disabling integrated graphics.
Once you’ve ensured all these, you’re ready to proceed.

- Right-click on the integrated GPU and select Disable device.
- Confirm the action when prompted.
- Restart Your Computer:
- This ensures the changes take effect and your system defaults to the dedicated GPU.
Important Note: If you disable the integrated GPU and your monitor is connected to its output port, you may lose display functionality. Always ensure your monitor is connected to the dedicated GPU’s output.
Method 2: Disable Integrated Graphics via BIOS/UEFI
For a more permanent solution, you can disable integrated graphics at the firmware level. This method is especially useful for systems where the integrated GPU reactivates after driver updates or system resets.
Step-by-Step Instructions:
- Restart Your Computer:
- Begin by restarting your PC to access BIOS/UEFI settings.
- Enter BIOS/UEFI:
- During startup, press the designated key to enter BIOS. Common keys include
Delete,F2,F10, orEsc. - Watch for a message like “Press DEL to enter setup” during boot.
