I have a Lenovo T530 with an Nvidia 5400M GPU, It is docked into a Lenovo docking station with 2 DVI monitors plugged in. Today I unplugged one of the DVI cables while both monitors were turned on and plugged it back in, this resulted in both DVI outputs changing from color to grayscale (black and white) output...
I have tried: rebooting, redocking the laptop multiple times, changing the windows display settings(resolution, color, etc) nothing will turn the color back on.
If I undock and use the built-in laptop display the color is fine.
How do I fix this?
