CRU / Dell P2720D / pixel clock / add monitor data

[sempronius]

Thanks for your answer.

- Does this mean that when lowering the resolution from the native resolution and selecting "GPU scaling: no scaling" the same pixel clock is used (and maybe exceeded) as when using the native resolution?

- lower resolutions seem to be defined because they are visible as standard resolutions in CRU, but still the "display scaling: no scaling" option does not work, everything is stretched to fullscreen, there are no black borders with the smaller image in the centre (as with GPU scaling: no scaling)
