As manufacturers have told us time and time again, narrow display bezels require the use of special panels. The bezels of the XPS 13 9370 in particular are as narrow as they are partly because Dell was able to source compatible panels from Sharp for both its FHD and 4K UHD SKUs. Unfortunately for said panels, they suffer from an often overlooked characteristic when it comes to the Ultrabook form factor.

As our measurements and table below show, both the XPS 13 9370 FHD and 4K UHD displays have very slow response times for significantly more noticeable ghosting than your average notebook or desktop monitor. The black-to-white response time, for example, is about 23 ms on the new XPS 13 compared to 8 ms or faster on modern desktop monitors. Even competing Ultrabooks like the Asus Zenbook 13, Huawei Matebook X, Apple MacBook Pro 13, and older XPS 13 9360 have much faster black-to-white response times as low as 12 ms. Similarly, gray-to-gray response times are equally as slow on the new XPS 13 relative to other Ultrabooks in its size class.
