Screen resolution of GS60 2PC003 Ghost gaming laptop?

Question

I picked up a lightly used MSI GS60 2PC003 Ghost laptop and am puzzled by the screen resolution reported by several programs: 1366x768. I also see this when I boot Linux Mint from a USB flash pen drive. The MSI specs web page says
LCD Size 15.6" Full HD (1920x1080), Anti-glare
so did someone swap the display? The specs page also says "The specifications may differ from areas and we keep the right to change without notice." Would the serial number help to determine which display it was assembled with?
The seller says he bought it in the US (in Florida, I think) and brought it back to Uruguay where we both live. It's a US English lappie.
I'm suspicious about the laptop now because the 1TB HDD is reporting a fatal error after just 8 hours of power on time.
TIA to everyone who replies.

Answer 1

The lappie has Window$ 8.1 and it's totally up to date. That's one thing the guy I bought it from did--he always kept the M$ stuff up to date.
Every program I've tried shows the screen resolution is 1366x768. There's no higher resolution available as a choice, just lower resolutions.
Linux runs a hell of a lot better than Window$ does on the laptop. After I make a recovery backup, I intend to replace Window$ with Linux. A live Linux CD ISO running from a USB flash pen drive shows I'm not using any proprietary drivers under Linux and that's the way I want it.
I have a 1TB desktop HDD in a USB cabinet. Window$ doesn't see that external HDD and Linux does. There are a lot of other reasons not to use Window$; ask Ed Snowden.
I did have to update the BIOS from 103 to 111 and install all the driver updates in the order listed on the MSI web page. Nonetheless, the touchpad works fine under Linux and terribly under Window$, no matter how I adjust the Window$ settings for the touchpad.
I'm running DRevitalize from Hiren's Boot CD on the GS60 now to try and repair the HDD; it's going to take another day or so to finish. I've also got WinDFT from HGST, the HDD manufacturer's drive fitness test. Unfortunately, it doesn't attempt repairs like diagnostic software from some other manufacturers do. If it still fails SMART like I think it will, I'll try some disk repair stuff from Ultimate Boot CD before I buy a replacement HDD. 1TB isn't big enough for me anyway.
The HDD failed a few days after I bought the lappie. I've attached a screenshot of diskmgmt.msc taken the day before the HDD failed. It was good then. Very strange.
