Just got back from exchanging the 701d for the 801d at Costco, haven't had time to tweak anything yet but initial impression using the calibrated mode - way better than the 701d, will be able to tell more tonight once it gets dark as our living room is really bright but minimal clouding and flashlighting noticeable now during the day. The Vizio logo screen on startup is like 1000% better than the 701d I had.
For the remote - I would call it marginally better, don't have to be so exact with pointing it at the exact lower left corner by the power indicator. Oddly enough though, the Brighthouse HD box remote is worse on this one than on the 70", can't bounce the signal off the walls anymore, has to be at least pointed at the TV for it to work. Don't know what to make of that in terms of remote vs. TV. We use the Brighthouse as a universal most of the time anyway so I am OK, still hoping Vizio sends out the update for the wifi remote ability though.
Update installed the first time I turned it off and back on again after getting it set up with the wireless - we powered it on and plugged in the power and the HDMI cable into HDMI 1 port to check and make sure screen wasn't cracked, dead pixels, etc. - then turned it off but left it connected and plugged in, lifted it out of the box and had a friend attach the stand. Then plunked it down on the stand. We are using a 'fake' AV stand - two IKEA Malm coffee tables - the 801d actually fits it perfectly in width, literally almost exactly the same width as the two IKEA coffee tables together (only issue I see thus far with the tables is the shelves are a little weak, my Pioneer sc-1522 bows it a litte bit and due to having the middle legs there, the center speaker can't be right in the center, I have it on the shelf on the left table, the Pioneer on the shelf on the right table.)
Size wise, can't believe how noticeable the 10" difference is, the 701d was a big TV, the 801d is huge and has way more WOW! factor in terms of sheer size...we had upgraded in the past from a 46" to a 55" and didn't notice nearly as much difference. The 801d is just plain massive. Also can't believe the weight difference - 701d was just under 98 lbs with the stand, which is pretty heavy, this one is like 136 according to the box, those 10" are heavy! Don't have the two side by side to compare as we returned the 701d, then picked up the 801d the same visit but I think the stand on the 801d is wider and heavier, at least I hope it is and I am not imagining it - almost 40 lbs heavier than the 70".
Will report back more when I have a chance to tweak the settings and watch some content tonight in a dark room.
