CRU / Dell P2720D / pixel clock / add monitor data

[sempronius]

I still do not understand, sorry, why one monitor (HP 27xq) can do "no scaling" when using "display scaling" (centered image with black bars), whereas the other monitor (Dell P2720D) can only achieve "no scaling" when using "GPU scaling" - NOT when using "display scaling". I mean, the lower resolutions (in case of the Dell) had also been added by the graphics driver because they were there even before I started using CRU.

Is this simply a limitation of the capabilities of this monitor as opposed to the HP?

Please, excuse me being stubborn, or perhaps, I am just confused, tired...
