I have/had a problem with my desktop not showing icons, namely spacing properly in Windows 8.1 and 10.
In the process of trying to fix this, some of the suggestions talked about laptop (Acer Aspire S7-391) screen resolution/native resolution.
This laptop has native resolution of 1920×1080.
When I check either Control panel in Windows or Intel HD graphics control panel, it does indeed show my resolution is 1920×1080 but when I check my real resolution, for example websites or Youtube's video stats, it shows 1280×720@60Hz.
My question is why this happens. Why does Windows show one resolution when the output is clearly different.
I tried disabling Intel graphic driver which sets resolution to fixed native resolution without option to change it but still outputs 1280×720.
I also changed driver to Acer driver for my laptop (VGA_Intel_9.17.10.2867_W8x64_A) as well as the latest Intel HD4000 driver (15.33.38.64.4252). Neither helped.
How do I get my native resolution as output resolution on my Acer Aspire S7-391?

I believe that there is no problem.
The correct total screen resolution is shown by the Control Panel Display applet and by the graphics control panel and by the dxdiag utility.
However, websites report the resolution as given by the browser's JavaScript
window.screenobject (see reference), which is the adjusted size that is usable in the browser for displays in full-screen mode.This size is lower than the values reported by the computer, since the browser uses up a part of the screen for its own adornments, such as borders and toolbars and sidebars etc. , and Windows itself is also taking up a part of the screen with its taskbar etc.
In short : Windows shows the correct values and you have no problem. Do not replace your Windows display drivers, or you will create real problems.
