Symptoms

Keyboard or mouse use lags or is delayed while using the Dell P2815Q monitor.

Cause

Due to the P2815Q hardware architecture, there is an approximate 100-millisecond delay while the display processes video input data. This delay is not always perceptible, but sometimes a slight lag or delay in the mouse pointer response or keyboard input maybe noticed.

This lag or delay occurs regardless of the computer connected to the display or the ports used by the input device (Mouse or Keyboard).

Resolution

Changing the display to GAME mode reduces the lag or delay dramatically (Figure 1 [English only]).

The 100-millisecond lag or delay in the display response in the NORMAL mode is a result of the display technology. Replacement of parts or updates to the setting does not resolve the issue. The lag or delay may not be noticeable.
