My almost-new desktop Wintel PC has suddenly started to display in [EDIT] greyscale [EDIT] for no obvious reason:

 

Hardware:

 

Gigabyte Z370N mini ITX mother board (I have three of these boards - no problems with the other two PCs)
Intel i5 Coffee Lake (Gen 8) CPU - not overclocked
16GB DDDR4 RAM
Samsung SSD system drive (M2)
NVIDIA GeForce GTX 3GB graphics card, with latest drivers
Windows 10 Pro 64-bit, fully updated
32" BenQ monitor (2560 x 1440)

 

At cold boot:

normal white-on-blue text
then normal hi-res screen saver in colour
then a hi-res [EDIT] greyscale [EDIT] screen

 

Testing:

 

swapped monitors - no fix
swapped display port leads - no fix
swapped graphics cards - no fix
system restore to 4 weeks ago - no fix
back to older graphic card software - no fix

 

The PC runs cool - Speccy shows a CPU temp of 29C and the graphics card is 37C

 

Your advice please  frown

Party like it's 1991. Amber or green?

To clarify, by "monochrome" I mean "greyscale" with no colour tint.

If its Windows 10 - try CTRL + WINKEY + C

 

It toggles the colour mode that is buried in the settings app.

 

I've had this when a user was trying to use the shortcut keys for copy (CRTL + C), but accidentally held down the windows key just next to it. Probably how thousands of people have come across this.

Instant fix!

 

The color filter had been accidentally switched on.

 

Thank you.  smilesmilesmile

Its also a good prank for friends that leave their machines unlocked. Because its a new feature, quite a few tech savvy people don't know about it.
