Hi @Laurie23, I've moved your question into its own separate thread, because there's so much to discuss here.
First, can you elaborate on this?
What kind of website? I mean, for what purpose are you uploading your photos to it?
They should come from a printer that's a step above a supermarket kiosk, if you know what I mean. Do you have a camera store near you? They'll probably do printing.

Hi @poorejj, I completely agree, it often is very difficult to find out the exact technology in our screens.
Even though you're not into photography, you do still need some prints in order to calibrate. Do you have some?
