HELP -

I have been PP on my Dell US27 monitor (which I love) since I bought it 6 months ago. I had the settings to sRGB, and printed some photos professionally for the first time yesterday and they are nothing like my screen, they are dark and flat, and horrible.

how on earth do I calibrate this monitor (I naively thought it was self calibrating)?

I've tried to research it, but I am getting confused with the conflicting advice.

Ideas please!!

This shows two of my photos - one on screen, and one printed.....
