pc refuses to use GPU alongside integrated graphics
Hello, I'm trying to use my PC's built-in graphics but can't connect another monitor. My integrated graphics work fine when I remove the card, but they freeze whenever I plug in the right cable. The issue seems to depend on which GPU is connected—my RX 6400 works with IGPU, but the Intel HD Graphics 2000 freezes everything again. The CPU is an i7-2600 and both monitors are 27-inch LGs. The BIOS has "Integrated Video" enabled.
Have you attempted refreshing both dGPU/iGPU software with DDU (Display Driver Uninstaller)? After saving the file, follow this tutorial: https://www.wagnardsoft.com/content/DDU-Guide-Tutorial My choice is to install the latest drivers first for both your GPU and iGPU. Then remove the existing driver packages (via Add or Remove Programs). Disconnect from the internet, power off the machine, then restart. After OS recovery, launch DDU—it will prompt you to choose a version. Select Intel from the list, click Clean, and skip Restart. This may take a few minutes. Next, pick AMD, click Clean, then restart. Wait for the process to finish before trying to reinstall drivers once you’re back online. Ensure only your GPU is connected during this process.
The issue might be related to your AMD card and Intel GPU compatibility. Could try alternative drivers or check system requirements. Let me know if you need further help!
Since it's a prebuild, it could relate to that. It might be more efficient to connect the right cable directly to your GPU rather than managing an iGPU.
First, it’s important to realize that the two components can’t operate independently without special setup. You might be able to boost certain apps with the built-in graphics card, such as Intel QuickSync, but for gaming or detailed rendering you won’t achieve much. If you have an AMD APU and a basic dedicated GPU, you can combine them via hybrid crossfire mode, though this is only available on AMD systems. Even then, results won’t match what you expect. There are several reasons why developers restrict combined use. The main issue is that the faster graphics card will always be limited by the slower integrated one, causing lag as your system tries to keep up. This isn’t ideal if you want better performance. You might wonder why you’d combine them when a single high-quality GPU would suffice. In reality, Intel HD 2000 struggles with CSGO even at low settings, and frame rates drop significantly. For improved results, invest in a matching GPU and enable Crossfire instead. Edited January 18, 2023 by WackySpace
He seems to be attempting to utilize the iGPU for a second display, which is both feasible and reasonable. Typically, running both iGPU and dGPU concurrently works fine. Generally, you can handle simple operations like adding another monitor on the iGPU without much trouble. Yet, certain motherboards may have issues and not function correctly. Most users manage to get it working without major problems.
