I just bought a couple of Dell U2414H monitors, but I don't think this has anything to do with the monitors.
In windows the black levels are perfect, but in Ubuntu the black levels are way off.
Using the test image found at Lagom LCD test I can see all the squares using windows, but only down to 4 using Ubuntu. Why is that, why are the colors/contrast different?
- Nvidia GTX 770
- Dell U2414H, connected using DisplayPort, sRGB mode
- Ubuntu 14.04
- Nvidia driver version 331.38
