Backlight bleed or shadows appearing on Dell InfinityEdge borderless monitors

The Dell InfinityEdge borderless monitors may appear to have backlight bleeding or shadows/blurred edges. This article provides more information on this and guidance to mitigate this on your monitor.

Backlight bleeding and shadows on Dell InfinityEdge monitors

The Dell InfinityEdge borderless monitors may appear to have backlight bleeding or blurred shadows around the edges (Figure 1 and Figure 2). The following S2719DM, S2419HM, U2417H, U2717D, U2717H, U2419H, U2518D, S2718D models may be affected, as well as other Dell monitors with the InfinityEdge design. This can occur due to the borderless design of these Dell displays and is working as designed as these are borderless monitors.

The blurred edges should only be visible when there is no task bar at the bottom of the LCD panel. During standard usage, you should not experience the blurred edges or shadows.

NOTE: Please be aware that some light leakage is to be expected when viewing images with dark backgrounds in dark rooms.
Dell monitors are not validated in a darkened room. Dell Consumer monitors are inspected at 150lux ambient lighting (similar to typical office lighting).
Dell UltraSharp monitors are inspected with a tighter criteria of 70 lux ambient lighting (dimly lit room but not completely dark).
