The Latitude 5491 is equipped with the same glossy touchscreen IPS display from AU Optronics (type AUO133D) as the Latitude 5490 we reviewed a couple months ago. At an average of under 200 nits, the panel is very dim - many notebooks like the ThinkPad T480 / T480s are roughly 100 nits brighter. The HP 840 G5 trounces all competitors in this regard, as its panel exceeds 600 nits. At 82 percent, the brightness distribution is rather poor as well and the right side of the panel gets brighter than the left, although that isn't a problem during normal use.

Our high-end model comes with the FHD (1920 x 1080) embedded touch display, but Dell also offers an anti-glare regular FHD panel and an anti-glare HD (1366 x 768) display. The review unit suffers from very noticeable screen bleeding, particularly on the right edge. Despite the low overall brightness, these areas are visible on black backgrounds even during the day. Dell doesn't use PWM to regulate the display brightness, so flicker-sensitive users can rest easy should they decide to purchase this notebook.
