AutoCAD: Blue Color Shown as Red, Red Color Shown as Blue

If you use AutoCAD and recently installed a new graphics card, then you might have noticed that when you draw a blue line, it shows up as red, and when you draw a red line, it shows up as blue.

According to Autodesk’s website, the problem is only with a specific graphics card chipset (AMD Firepro W4190M), but I had this problem with other cards as well.

In order to solve this issue, all you have to do is to disable hardware acceleration in AutoCAD.

How to Disable Hardware Acceleration in AutoCAD

There are several ways to toggle hardware acceleration in AutoCAD-based products. Try one of the following methods:

  • Enter the GRAPHICSCONFIG command and click the Hardware Configuration button.
  • Enter the 3DCONFIG command and click the Hardware Configuration button.
  • Enter OPTIONS on the command line or choose it from the Application menu to open the Options dialog box. On the System tab, click the Graphics Performance button. Then click the Hardware Acceleration button to turn it off or on.
  • Click the GRAPHICSCONFIG performance button in the lower-right corner of the AutoCAD application window.
