How to teach Surface 2 Pro to be a desktop, not a tablet?

Question

Microsoft

Hey!
I've been calling myself a web designer for some time now, and I'm using a Surface 2 Pro with Windows 10TP.
These two facts are in the same sentence, because I can not fully work due to the following problem:
Surface is recognized as a tablet in browsers, despite the fact that its resolution is 1920x1080 and at the same time I work with a second monitor 1920x1200.
To be precise, in Chrome and Firefox, for example, parallax and a bunch of other beautiful goodies from a number of animations do not work for me (everything is static), but in IE11 everything works with a bang. When laying out a landing page for desktop, tablet and very small devices in Muse, I always see the tablet version (in all browsers).
The desktop version in my case differs from the tablet one in that the desktop has fullwidth, while the tablet receives all the content <meta name="viewport" content="width=768">and sticks on the left side of the screen. At the same time, if you remove the tablet version from the site (in the site layout in Muse), then the full desktop version is displayed.
Here is how Adobe employees answer the question "Is the Surface defined as tablet or desktop?":

There are multiple factors that come into play when determining which rendition to present to our users. These factors include the renditions available with the Muse site, where the site is hosted, and which browser the user is viewing the site with.
If the Muse site is hosted on Adobe Business Catalyst, the appropriate rendition presented is determined server-side.
If the Muse site is hosted by a third-party service, the browser determines the ideal rendition to display depending upon the screen's dimensions and whether it is touch-enabled. From there our JavaScript determines which site is presented if the ideal rendition is not available.
In regards to the Surface we currenlty consider it a Tablet, but it is going to vary from device to device. We use screen size and touch capabilities to determine the rendition.

And now the questions with which I turn to you for help:
What to do with Surface so that it is defined as desktop everywhere?
If it's impossible "everywhere", then how can I force Surface to be defined as desktop on those sites that I myself make up?
Is this a Windows, browser, or site code issue?
Or is it all because of the touch screen?
Thanks in advance!

Answer 1

Is Tablet Mode enabled in Windows 10?

Answer 2

How can the server determine that the user has accessed the site from a touchscreen phone or tablet?
Get acquainted with how tablets are defined and do the opposite
(change the user agent, ppi and what else the developers came up with to determine)
