I suggest you get the drivers from ASUS, even if they are older. I have seen issues with more recent drivers caused by odd or out of spec hardware not supported by official drivers. Annoying, yes. Installing drivers from manufacturers, especially on laptops, can fix this type of problem.
BTW the spec page for this at ASUS oddly lists both resolutions under display. I have no idea why.
Driven by innovation & committed to quality, ASUS has a wide selection of best in class products. Find & buy a laptop, phone, router, monitor, motherboard & more
If the drivers are indeed the latest then try an older driver and see if it makes any difference.
Another thing that you could do, just for testing, is to run a Linux live DVD/USB such as Manjaro, Mint or Ubuntu. You can see then if higher screen resolutions are available or the same as in Windows.
