I have recently installed Photoshop and LR CC on a new computer (Dell Precision T7600). Previously color-balanced and printed images are severely magenta. The files look fine in preview but change to magenta when opened. Web images, powerpoints and pdfs look fine unless opened in Photoshop or LR, at which point they turn magenta. The background color in LR and PS is not magenta. Just the images. Could it be a glitch in the CC download or a problem with the new video card (NVIDIA NVS 310). Or something else. Help. I can't work.
Your display profile is wrong, and the two color managed applications you use (which are the only ones paying attention to the display profile) are trying to compensate for the incorrect display properties.
Fix the display profile (in the OS display settings) so that it correctly reflects the properties of your display.
Thank you very much.
