thanks for your reply
ok i'll try to explain the problem is white color shines like a sun.
here is the real picture of the white fashion ( screenshot)
and please compare it to my mac screen
also if i went to desktop i can see previous page colors on the display
White is, well, white, and naturally will be brighter than the grey background in your first post.
Turn your screen brightness down a little.
I now notice that the one image of a man with clouds in the background, shows some kind of "cross-hatch" effect on that part of the image. Is THAT what you want us to see? It really does help to describe what you see; also, that effect would be MUCH more noticeable if the other images were NOT showing, with just a blank screen.
And, turning the brightness down a notch or two can ALSO help if you have some minor image retention.
[doublepost=1527949459][/doublepost]How did you get the file labels reversed like that?
Try this:
Open System Preferences, then Accessibility.
Click on the Display tab. You SHOULD see a couple of sliders. One will be Display contrast. Make sure that control is on Normal (completely to the left), and then
un-check all the boxes above that slider, if any are checked.
What is the icon in your top menu that looks like a tool box (I am not familiar with that one)
Are you using an external display, or screen sharing, etc? Try disconnecting that external display
