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?
The first step is to compare your screen to your previous prints. If your screen still matches them ok, then you know that this was just a dodgy batch.
