I just got a new monitor for my 07 Mac mini. It works great and has excellent picture quality for everything except for all of my iPhoto pics. In any mode, including full screen, all of my shots are now slightly blurry. If I press one or two on the keyboard to zoom in, in full screen mode, the zoomed in shot then becomes clear. If I click zero and display the whole photo it becomes blurry again. I can right click on a pic and click show in finder and then open the photo in preview fine. The pictures then look tack sharp as they should. My old monitor didn't do this, all of my photos looked sharp in iPhoto and the same in preview. The new monitor isn't at fault since preview will show the pics sharp on it. What can I do here to fix this? I am currently running the latest version of iPhoto 8 on 10.6.8. Would upgrading to the new iPhoto version fix this issue? thanks! Edit I would also like to add that photos now have a different color tone. A photo displayed in preview that is pure white shows up as creamy white in iPhoto. I can place the same image side by side while open in preview and iphoto and can clearly see the difference. Again, none of this happens when my old monitor is used.
