Tool to help Synchronize Monitor Color and Contrast

[Traverse]

This may not even be possible, but it is very difficult for someone who is colorblind.

I have a new Dell Ultrasharp U2415 and an older LG 23EA63 monitors. The color and contrast are very different right now and it is kind of jarring. Is there any online tool that can help sync the two?

It doesn't have to be perfect, but closer would be nice.

Additional question.

I don't always need the secondary monitor, but will use it off and on and don't really want to constantly unplug the port. Will it hurt anything to just leave it plugged into my Mac, but turn it off?

I know that video memory will still be shared, but the 750M shouldn't struggle with a 1920 x 1200 and a 1920 x 1080 display.

- Definitely not. That 750M can do two 4K displays, so it won't even break a sweat with your lower-res monitors.

And do you know of any tool that can help a colorblind person calibrate the display? When I get it like I like it I realize that colors are often over saturated. I want a display that is more natural for when I use Lightroom.

- Nope, not a clue. Sorry.
