Hehe, I could shave it in just like my 85u!
I could see where it would annoy, but Im used to plasmas so it does not bother. One plus is that the reflection area still shows a dark black during the day. My plasma seemed to have green blacks during the day, but I think it's just the screen coating.
If I had to pick a better daytime screen, it'd be the shiny Regza.
As far as your Dad goes, I cannot stop saying how good the price is on this model compared to other LED local dimming sets. The LG LH90 is nice, but has less zones and is just a fugly tv. I also do not like their Trumotion programming.
From what I understand, the 670u is a Samsung 950 panel, with Toshiba addons and programming, which might be what allows the lower price. This is not substantiated though.
Local dimming zone numbers are what helps in better blacks, so I've found a way to test the zones, and will do so tonight. Someone tried it on a LH90, so I'm gonna try the same experiment on my tv to confirm.
LH90 96 zones
LHX55 240 zones
