Review on Dell UltraSharp 104P6: 27" 2560X1440P Monitor with Plug and Play, Built-In Speakers and Kensington Lock (Discontinued) by David Nelson

While the low price is tempting, you might be better off considering a different monitor. This monitor has a motion sensor that brings up the settings menu. These sensors in Dell monitors are prone to failure. And now I see this menu popping up several times an hour. There's no way to turn it off: you can simply reduce the time the menu stays on screen to at least 5 seconds. Dell has poor warranty length and coverage, so it's wise to avoid their line of monitors altogether.
