Mac Mini Sleep Issue

ok, posted little @ 1 time, think have more/better info now. have mac mini doing 2 strange things seem related monitor going sleep.

first, when open system preferences , go energy saver, set computer , display same time sleep, 5 minutes. after 5 minutes display turns off , message hp monitor says "display going sleep" goes black. same message comes saying "display going sleep" goes black again, keeps doing on , over.

if hit power button once put computer sleep mode, display goes off should , fine.

tried hooking display(hp 2311x) hdmi , minidisplayport dvi adapter , dvi cable, same results either way.

turned off "wake bluetooth" after reading having issue mouse kept waking there computer, didn't change anything. though, if let mac , display both go sleep on there own, the bt trackpad still turn on, making me think mac not sleeping. if hit power button put mac sleep, bt trackpad won't wake up.

monitor goes sleep when hooked different pc no problems.

second issue when wake things up, display has pink hue it, have put mac sleep , wake , pink hue gone. never if force sleep apple menu or using power button, when let go sleep on own.

sorry long post, can't figure out, , if problem mac, have exchange monday under return policy. go ahead , this, got 10% discount , have buy new 1 @ full price. if problem mac have no issue that, hate spend $60 , still have same problem.
