Please can someone explain the difference between the new WD8 and HD8 panels. My understanding was that the WD8 would not be HD complaint due to its resolution of 852x480. I now see it advertised as HD Compliant and SKY HD Complaint and I am now confused. I want to buy a Series 8 panel that is HD Compliant but am not sure of the advantage of paying c£1000 more for the HD8. Any advice would be much appreciated as I am afraid that this HD stuff confuses me.
