Then it's time for a new screen. Let's not waste any more time on this.
However, when I say "new" I don't actually mean new. https://www.facebook.com/groups/195567190503489/permalink/2659777307415786/
It really sounds like graphics card interference in your new computer, doesn't it? I can't think of any other explanation.
Maybe see if it's possible to temporarily turn off the graphics card?
If the file (in Photoshop or Bridge) doesn't match the print, recalibrate until it does. Follow the troubleshooting part of my directions.
Also, make sure you aren't just comparing one print. Gotta have half a dozen if possible.
