In the continuing quest for total redundancy I had both of my laptops running side by side. Samsung A10/Acer aspire 3000.
I was transferring picture files and noticed that the screen on the Samsung made my pics look much better. Difficult to describe but on the Samsung they seemed to be "richer" and "deeper".
Further investigation showed that the Acer screen was set to maximum brightness,sorted that and things looked better, but still not as good.
Looked for other fiddle controls with no success, any hints or tips? Or is just cos the Acer screen ain't as good?

Keep it simple.
