operation

WhenconnectedbyUSBorexternal5Vsource,adapterdefaultstofullpoweron,withstatusLED

glowingBLUE.

OnepressonpowerbuttonwillswitchtoSTANDBYmode,whichturnsoffbacklight,butkeeps

DisplayPortconnection.Thismodeisusedtokeeppowerconsumptionlower,ortosavebacklight

lifetime.Inthismode,statusLEDisglowingRED.

Tofullyturnofftheadapter(includingdisconnectfromDisplayPortsignals),pressthepowerbutton

twice.

SincemostcommonusecasedoesnotinvolvedisconnectingfromDisplayPort(asthiswouldcause

othermonitorstoflickerwhiledisplayadapterisreconfiguring),ifadapterisinstandbymodeformore
