I got my M801d.
Okay, I finally hooked everything (almost) back up since I was swapping in an entertainment TV stand too replacing my old CRT projection 1080i Sony TV (2005 model).
Delivery went smooth and painless.
Unfortunately, my setup has a mix mash of older component DVD player, and my receiver is my HDMI switch but does not support 3D. I have my cable box HDMI straight to the TV and Blu-Ray player HDMI straight to the TV with the optical out going to the receiver for now. Dolby Digital works, but everything else like DTS gets downmixed to stereo PCM. Oh well, next year's shopping list will be a new receiver and new Blu-Ray player.
I watched some stuff for awhile and then calibrated the TV using the Disney WOW disc. I only did the guided / simple calibration for now. I'll probably tackle the advanced mode Sunday, when I have more time.
My settings are as follows but will probably be slightly tweaked soon:
Color: 65 (more on this)
Tint: 0 (did not adjust yet although looks very good)
Sharpness: 25 (although everything below 50 isn't too bad)
All enhancement modes off except smart dimming.
Smooth effect gave major SOE even on medium so I obviously disabled that.
I left film mode to Auto.
Smart dimming obviously has its limits, and using the Disney Wow disc, you'll adjust your brightness and the horizontal white bar will cause noticeable blooming on the right part of the screen although it's not too obnoxious. In regular TV and movies playing, smart dimming is so unnoticeable, I can't think of any reason to disable it.
Dirty screen effect. Very minimal. I notice slightly dark spots on the four extreme corners of the TV and very slight band along the bottom (maybe a half inch) but it's not very pronounced unless you have a very smooth solid color image on the screen. Coming from my old TV it's not an issue at all, and I've seen worse from what some people have posted pics on this forum.
Viewing angle. Minimal color shift and very much looks like my PC IPS screen, so I'm about 95% positive that's what they are using here.
Banding can be very pronounced depending on the source material which is not the TV's fault. Some cable channels showing like Finding Nemo in a dark scene to light circular scene looked so horrible, it shows what happens when you watch overly compressed material. Being larger and not analog like my old TV, the picture quality is not at all forgiving.
3D and Blue-Ray. Blu-Ray material looks absolutely fantastic! Bought Despicable Me in 3D (my first home 3D film), and I thought I was sitting in a theater! My wife absolutely loved it! There is some 3D bleed / cross talk but it's not the headache inducing flicker like active 3D does. I definitely prefer passive 3D. That said, I can make out the scan lines on this huge beast of a TV. It's noticeable but I knew that from other reviews I read so I'm not disappointed. I can see why 4K will be needed to really give theater quality 3D at home. Blu-Ray 3D definitely seemed crisper and less bleed than cable. I tried both HDMI and component and both work with 3D mode. 3D mode can be manually selected even HDMI so no problems there. Firmware is 1.05. This 80 inch came with only four pairs of glasses by the way.
Color is very rich on this TV, and it looks like it supports a deep color gamut. I have mine set at 65 which gives nice rich colors but some people may prefer less like in the 55-60 range.
FYI, I sit about 9 feet from the TV which is probably a little close. I think 12-13 feet would probably be the sweet spot. The screen size at my distance make for a nice home theater screen so I'm very happy with it. I might be going to the movies even less.
I hope this will give people some much needed info, and I'll definitely post an updated review and settings probably Sunday night.
One final thing is the TV stand. It makes me nervous! TV can wobble with the slightest touch although the stand itself is very heavy. I have children coming over, so I will definitely have to figure out how to secure this TV better so it doesn't tip over.
All in all I give this TV 4.5 stars out of 5. No it's not perfect (the remote layout is bad too), but I have no problems in keeping this TV for the long haul which will be at least 5+ years.
