I have a Samsung laptop attached by HDMI cable to an LG monitor. I upgraded from Windows 8 to 8.1 this afternoon and now the monitor image is in greyscale. The laptop screen is in colour as normal.
I have tried updating the drivers for the monitor, but the latest ones were already installed. I'm puzzled. Any assistance much appreciated.
EDIT: Can't find a way to delete this post, but the issue is now solved. I opened AMD Catalyst Control Center and the colour saturation level had somehow gone to 0. Fixed!
