There are some advantages and disadvantages to each option with some being obvious and others not so obvious. We go over each one here to help potential buyers make their decision.

So far, we've tested three separate XPS 13 9300 SKUs: two with the FHD display and one with the 4K UHD display. Aside from the obvious resolution discrepancy between them, we've also found a handful of other differences worth mentioning especially if you're on the fence between one option or the other.

The first and most noticeable difference will be the glossy Gorilla Glass panel on the 4K option. Whereas the FHD version has both matte and glossy to choose from, the 4K option must be glossy due to its touchscreen support. This can be a deal breaker for certain users who swear by matte displays to reduce glare as much as possible.

The second difference relates to display brightness. When at the maximum brightness setting with the ambient light sensor disabled, we're able to record a brightness of 414 nits on the 4K display and ~610 nits on each of the two FHD displays. If you intend to use the XPS 13 outdoors frequently, then an FHD SKU will be the better option.

Thirdly, black-white and gray-gray response times are surprisingly faster on the 4K panel than the FHD panel. Usually, the opposite is true as 4K panels typically have slower response times than their FHD counterparts. This means that you'll see less ghosting on the 4K XPS 13 9300 than on the FHD XPS 13 9300.

And lastly, pulse-width modulation (PWM) is present on the FHD version whereas it is completely absent on the 4K version. You may want to consider the 4K option if your eyes are sensitive to onscreen flickering.

Other attributes like color space and contrast ratio are almost the same between the FHD and 4K panels. While battery life is shorter on the 4K panel by about 90 minutes, overall runtimes are still very long across the board at over 11 hours of real-world WLAN use.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
