Excellent, thank you! And even two versions I now using the first picture, let me explain why. This is my whole setup:
> Laptop 1600x900 (16:9) > Home pc 1920x1080 (16:9) > Monitors at work 1920x1200 (16:10)
Now picture 1 looks great at all 4 monitors. Picture 2 is also great but the two black stripes are really huge on the 16:10 monitors (which I understand because the picture is 16:9). Creating 1920x1200 pictures (16:10) however would not solve the problem because they would look a bit weird on the 16:9 monitors
So bottom line: picture 1 is the best on these different monitors.
