I have an HP laptop with a FirePro M5950. My main appalication is Creo CAD software. I have a problem with driver versions and Creo. I need to use v13.20 in order to get some functions of Creo to work properly.
However, although it all seems to work properly, my external monitor (via DisplayPort) has changed to monochrome/greyscale.
If use a vga --> hdmi adapter and plug that in to the display although it is not at full resolution it is color.
