Two Couples

I was photographing these two seagulls, then realized there was also a human couple walking nearby. Can you see them? I can see them on the laptop, but not on this computer.

I have determined that there's actually something wrong with this monitor. It's far too dark no matter how I adjust it--even after resetting and degaussing (which did help slightly, but not much). Thankfully, DH is going to switch with me since he doesn't do things like photo editing on his computer. I've tested his monitor, and it can be adjusted to display images properly with the tools Kevin suggested.
