Mine just arrived and also has scratches along the front lower bezel of the actual monitor. Otherwise the product doesn't look "used," just poorly packaged and shipped. All other components have protective stuff along them, etc. Nothing looked unboxed. Setting it up now...
Mine was the same - no external packing (same as everyone else), and on the monitor what look like fine scratches, or streaks under the bottom front bezel. The screen looked like it had been wiped over with a cloth or something (not what you would normally see from a factory unit I'd guess), but that cleared up easily with a microfibre cloth.
I can't see the scratches now the TV is upright, but I'll have to check again in the morning in better, natural light.
TBH I'm 50/50 glad/sad if its a refurb - from what I read the refurb units have got a much better chance of lasting and I figure for $99 I got what I paid for.
Anyways - you're not alone with what you got. I'm just letting mine warm up to room temperature before I start plugging stuff in - and then the real questions will be answered
