Umm... first and foremost they refer to it as a backlit LED panel. It is edge lit.
No Halos which in the form they describe it they mean blooming. It should be obvious to them considering their "expertise" that this is not a local dimming panel nor does the software based zone dimming work in movie mode, which is why there is no blooming...
They praise its bright room performance but knock it for its glare... all LCD look good in a bright room, it is a dark room where they suffer unless it is a full array local dimming panel, which in that case they are excellent in the sweet spot.
They praise its color accuracy, but the panel is not calibrated as the 10pt WB adjustment is set to off. So, accurate compared to what?
It is reviews like these that make it difficult for consumers to make an objective and informed decision.
