I took a lot of photos during a family get-together and I really liked many of them. My girlfriend then edited the photos to make them look better. The photos looked GREAT on her iMac monitor but when we viewed them on my monitor (which had higher brightness) we were shocked to see that every photo was suffering hard from grainy texture. This is mostly due to the high ISO on the camera at the time of taking the photos (dimly lit room) but also part due to my girlfriend increasing the sharpness on every photo because it looked as if we could afford it easily on her monitor.
Are they simply ruined or can they be saved? She didn't save the photoshop files so we can't simply take the sharpness down.

You'll see what I mean if you fullscreen them.
