Web Colors - Light Grays on PC not showing

I could be completely off but just wanted to see if there was anything on this subject:

I'm developing a site at the moment that includes a few DIVs that use different shades of really light greys for background and border colors. On both my Mac (laptop and desktop) the colors can be seen quite easily. However, on PC (both Firefox and IE) the colors are not there at all.

The cu开发者_运维百科rrent colors I have are #E9E9E9 and #E1E1E1.

The weird thing is when I change the colors to something darker like #CCCCCC the color is easily seen on PCs and I would assume I could put up a few more shades lighter. But when I move it to the next color like #DDDDDD the color is completely gone.

Just on a limb but is there any weird thing like PC's not rendering certain color codes or am I just trying to make something out of nothing here?

I've been in the exact situation and I had a hard time designing UIs because of this issue.

I'm on Ubuntu 18.04 and Chrome, either of which is not the problem. This issue resides in the monitor settings, in my case I'm using a Samsung Monitor.

I've solved my issue by doing the following:

• Reveal your Monitor Settings (via some button in your monitor).
• Navigate to Menu, and then go to Picture.
• Scroll down to reveal the other settings down below.
• Set HDMI Black Level to Normal

Instantaneously you'll see your black colors improved.

There shouldn't be any problem with a PC displaying those colors. It could be a problem with your PC's video settings or your monitor. Have you tried it with multiple PCs and monitors?
