What integrated graphics are and why you might disable them

Integrated graphics is the video processor built into your computer's main processor (CPU). It shares your computer's main memory and handles display output without needing a separate graphics card. Most laptops and many desktop computers use integrated graphics as their only video option.

You might want to disable integrated graphics if you have installed a dedicated graphics card (a separate piece of hardware made specifically for graphics) and want your computer to use only that card instead. This can improve performance in games or video editing, reduce power consumption on laptops, or solve conflicts when two graphics processors are competing for resources.

Disabling integrated graphics is different from straightforward switching which graphics processor your computer uses. When you disable it, the system stops recognizing it entirely. When you switch between graphics, both remain active but only one handles the display at any given moment.

Key Takeaways

  • Integrated graphics live in your CPU and share your computer's main memory, while dedicated graphics cards have their own memory and processing power.
  • You disable integrated graphics through your computer's BIOS or UEFI settings, not through Windows or Mac settings.
  • Disabling integrated graphics only makes sense if you have a dedicated graphics card installed and want to use it exclusively.
  • The exact steps and menu names vary by computer manufacturer, so you may need to check your specific model's documentation.
  • If you disable integrated graphics and your dedicated card fails, your computer may not display anything until you re-enable it.

Accessing your BIOS or UEFI settings

Integrated graphics settings live in your BIOS or UEFI — the firmware that runs before Windows or macOS loads. You cannot disable integrated graphics from within Windows or Mac settings; you must restart your computer and enter the firmware menu.

To enter BIOS or UEFI, restart your computer and press a specific key repeatedly as it boots. The key varies by manufacturer: Dell and Lenovo laptops often use F2, HP uses F10, Asus uses Delete, and some Acer models use F2. Your computer may display the correct key on the startup screen for a few seconds. If you miss it, restart and try again.

Once you are in the BIOS or UEFI menu, look for a section called "Integrated Graphics," "Onboard Graphics," "iGPU," or "Primary Display." The exact name and location depend on your computer's manufacturer and model. Some systems organize it under "Advanced" or "Chipset" settings.

Disabling integrated graphics on Intel and AMD systems

On computers with Intel processors, the integrated graphics setting is often labeled "Intel Integrated Graphics" or "Intel UHD Graphics." Look for an option that says "Disabled," "Off," or "PCI Express" and select it. Some systems offer a choice between "Integrated" and "PCI Express" — selecting "PCI Express" tells the computer to use your dedicated card instead.

On computers with AMD processors, the setting may be called "Integrated Graphics," "Radeon Graphics," or "APU Graphics." The process is the same: find the option and change it from "Enabled" to "Disabled" or from "Integrated" to "Dedicated."

After you change the setting, look for a "Save and Exit" option, usually near the bottom of the menu. The system will restart and explore the change. Your computer should now use only your dedicated graphics card.

What happens after you disable integrated graphics

Once disabled, your computer will no longer recognize the integrated graphics processor. All display output will come from your dedicated graphics card. If you have multiple monitors, they must all connect to ports on your dedicated card — ports connected to the motherboard will not work.

Your dedicated card will now have full access to the system's resources without competition from the integrated processor. This can improve performance in graphics-heavy tasks, though the difference is usually noticeable only in games or professional video and 3D work.

Power consumption may decrease on laptops, since the integrated processor is no longer active. However, the dedicated card typically uses more power than integrated graphics, so the overall power draw may not change much.

Risks and when to re-enable integrated graphics

The main risk of disabling integrated graphics is that if your dedicated graphics card fails or becomes disconnected, your computer will have no way to display anything. You will see a black screen even though the computer is running. To fix this, you would need to restart into BIOS again and re-enable integrated graphics, or physically reseat your dedicated card.

If you are not comfortable troubleshooting hardware problems, you may want to leave integrated graphics enabled as a backup. Modern systems handle having both active without significant performance loss.

Re-enable integrated graphics by entering BIOS again, finding the same setting, and changing it back to "Enabled" or "Integrated." Save and exit, and your computer will recognize both graphics processors again.

Switching between graphics instead of disabling

Many laptops and some desktops offer a middle ground: keeping integrated graphics enabled but telling the system to use your dedicated card by default. This gives you a backup if the dedicated card fails, while still getting most of the performance benefit.

On Windows, you can set which graphics processor individual programs use. Right-click on a program, select "Run with graphics processor," and choose your dedicated card. On some systems, you can also set a default in the graphics control panel (NVIDIA Control Panel, AMD Radeon Settings, or Intel Graphics Command Center).

On Mac, the system automatically switches between integrated and dedicated graphics based on what you are doing. You cannot manually disable integrated graphics on most Mac laptops, though you can on some Mac desktops through System Preferences.

Frequently Asked Questions

Will disabling integrated graphics make my computer faster?

Only if you have a dedicated graphics card and you use it for graphics-heavy tasks like gaming or video editing. For everyday tasks like web browsing or word processing, you will not notice a difference. Disabling integrated graphics removes a potential resource conflict, but it does not speed up your CPU or main memory.

Can I disable integrated graphics without a dedicated graphics card installed?

Technically yes, but you should not. If you disable integrated graphics and have no dedicated card, your computer will not display anything. You would need to restart into BIOS and re-enable it to see your screen again.

What if I cannot find the integrated graphics setting in my BIOS?

Some manufacturers hide it under "Advanced" or "Chipset" settings, or label it differently. Check your computer's manual or manufacturer website for the exact menu path. If the setting does not exist, your BIOS version may not support disabling integrated graphics.

Does disabling integrated graphics save battery on my laptop?

Slightly, since the integrated processor is no longer active. However, your dedicated graphics card typically uses more power than integrated graphics, so the overall battery life may not improve much. The benefit is usually noticeable only if you rarely use graphics-heavy programs.

Can I re-enable integrated graphics if I change my mind?

Yes. Restart into BIOS, find the same setting, and change it back to "Enabled." The change is not permanent and does not affect your hardware. You can toggle it on and off as many times as you want.
