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.
●→●→☀(BLUE–fullpoweron‐>RED–standby‐>Fullpoweroff(LEDoff)
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
thanafewseconds,pressingthepowerbuttonreturnstoFullpowermode,turningonbacklight.
●→●→Wait2+seconds→●(BLUE–fullpoweron‐>RED–standby‐>ifmonitorisinstandbyfora
fewseconds,pressingPoweragainwillgobacktoFULLpowermode(BLUELED).
Tochangebrightness,pressandholdthepowerbuttonformorethanasecond.Thisentersbrightness
controlmode.Inthismode,statusledglowingcyclesbetween2colors‐YELLOWmeansbrightness
DOWNadjustment,andPURPLEmeansbrightnessUPadjustment.Onceinbrightnessadjustmentmode,
shortclicksonpowerbuttonwilladjustbrightnessinstepsupordownrespectively.Holdpowerbutton
againtoswitchtonextmode,ortosave.
●→●→●→●Whenrequiredbrightnessisachieved,holdthebuttonuntilstatusLEDisglowingBLUE.
Thiswillsavecurrentbrightnesstonon‐volatilememory.
