The monitor I have is a Dell p2720dc - 27-inch display. Recently I have been using it with all 3 Operating systems. On Windows, although I have set the resolution to 2560 x 1440 pixels I find it does not create more desktop "real estate" that other operating systems Linux & MacOS do.
For example the youtube website gives a nice comparison see (all 3 share the 1440p resolution on a 27 inch display):
There is no scaling performed on Windows see display settings, however, things seem to be a little big. I have tried this solution mentioned by music2myear to lower the DPI below 100% however it seems that Windows 10 has disabled this option. This 27-inch display serves as my an extended display to my laptop screen (1600x900), yet things in scale comparison seem smaller there. The laptop I have is an Asus N55SL with a 1600x900 resolution 15.5-inch display. There is an Intel HD Graphics 3000 & NVIDIA GeForce GT 635M Cards.
Is there any way I can decrease the size of everything on the 1440p 27-inch display so that things have the same scale as macOS & Linux? If so can somebody point me to some help?
