Windows 10: Monitor lost color

I have Acer flat screen monitor which has been work very well for a couple years. After cleaning the desktop and keyboard the monitor still works except there is no color.

Any ideas

:)

 

My monitor has suddenly lost color

My monitor has suddenly lost color

 

Lost colors when connected to external display (projector)

Problem:

Colors are lost (only black and white tones) when external monitor is connected to computer. The computer's built-in monitor displays normally (with color).

Details:

Never had this problem before.

Didn't completely close presentation mode in PowerPoint (computer not connected to any external display) when I turned off the computer.

Then I turned on the computer, connected it into an external display, and when I turned on PowerPoint, everything on the external display was in black and white (color wash). All visuals (size, clarity, spacing, etc) are normal, except the color missing
on the projector screen.

I can flip between Duplicate Display, Extended Display, etc, but the color on the external monitor/projector is black and white.

The color on the Built-in monitor continues to have normal color.

When I restart the computer (with the external display connected), the colored blue windows boot logo is displayed normally on both the built in monitor and the external monitor. It's when the computer completely boots up that color remains on the built-in
display, but loses color on the external monitor.

Additional notes:

I think something has triggered Windows to "export" "lost" colors on the external display.

I don't know if AMD Catalyst Control Centre (Color:32 Bpp, 1920 x 1080, Landscape) has anything to do with this. Tried disconnecting cables, Restarting computer, common troubleshoots, etc.

The problem isn't the external monitor/projector. It displays color normally, even when tested with other computers.

Your help is much appreciated! Thank you!

 

You hit a keystroke combination while cleaning. Hit Ctrl-Winkey-C and your color will come back!

Hello Howdog, and welcome to Ten Forums. *Smile

It sounds like you may have turned on Color Filters by mistake pressing the Win+Ctrl+C keys while cleaning. The default color filter is "Greyscale" for what you're seeing.

Pressing those keys again will turn it off.

That happened to me last month.

Lucikily, Windows 10 build 17083 and later will include a setting to enable or disable the keyboard shortcut for Color Filters.
