Dell advertises a brightness of 500 nits for its XPS 13 9300 FHD SKUs. Interestingly, we're able to measure a maximum brightness of 600 nits on two different FHD SKUs to be brighter than what Dell is advertising. We've discovered that the display will automatically dim to a maximum of 500 nits only when disconnected from the outlet and running on battery power.

Fortunately, it's possible to get the full 600 nits when running on battery power with a few clicks as detailed here. Users will have to disable adaptive brightness via Windows, then disable adaptive brightness again via the Intel Graphics Control Center software, enable Display Power Savings, and then disable Enhanced Power Saving in that order. It's a convoluted process involving multiple boxes when it should have been just one or two clicks at most.

It's worth noting that the XPS 13 9300 uses the exact same 13.4-inch 16:10 Sharp LQ134N1 IPS panel as found on the XPS 13 7390 2-in-1 and so both systems share very similar characteristics. Even their pulse-width modulation frequencies are the same at 2500 Hz to suggest that they may share other similar components.

Eyesafe technology is included by default to reduce blue light emissions without impacting the color profile or accuracy of the display. Even so, our CalMAN measurements below show that the display could be even better calibrated than its default out-of-the-box settings.
