Thank you for your help, but unfortunately, still reverts back to normal. I'm wondering though, could this be a problem?:
You see how it says display 1|2 in the color management? When I click identify monitors the 1|2 shows up on the screen. But when I do Identify in 'Screen Resolution' it just says '2'. So maybe it is switching back to the generic plug and play...
Using the drop down box you have highlighted select the ghost device and if there is a colour profile for it then delete that profile. Search for an inf file that may exist which related to a previous monitor, it should not be hard to find - and delete it too.
Finding the inf file means searching for *.inf and specifying something you suspect would reside inside the file, like the make or model of your prior monitor, or it's resolution.
If you open the inf file I've provided in notepad you'll see the sort of content contained :)
I've deleted the color profiles, and there was only one other monitor I have ever hooked up to my laptop. I have done a search for the .INF for that monitor and there does not appear to be one.
I would be tempted to try a registry cleaner that allows you to make selective deletions in that case, but DO MAKE a full registry backup first as a precaution... :)
