The picture is fine. Takes a bit more tweaking than an E-Series to get right, esp. w/ saturation.
Off-axis just as bad as any -VA type panel.
Great that it's 1080p
Supposedly most Ex-C2 Series and lower Vizio panels are -Native- 60Hz (not "effective"), so maybe 60Hz isn't so bad in this set.
I didn't notice any of the Cable TV, or VOD playback blurriness attributed to D-Series in other reviews, ex: by rtings.com. It looked fine.
Bootup-time & Smart functions are just as fast to start, or maybe 10% faster than my E40-C2, so that's also good.
Haven't tried them, but headphone & VGA on the back is pretty good to have. I've read mixed-reviews using it as a computer monitor, though.
The real problem is the Audio System.
It's not that it's tinny-sounding.
It just distorts the Bass frequencies of all the music I tried on it. Anything like a bass-guitar, or something low & more sustained than ex. a kick-drum hit.
-I also verified this on 3 separate units in 2 different stores with the exact same settings, and same music, at reasonable (not crazy) listening volumes.
This is with surround on or off, and even Volume-leveling on or off, Eq: flat. Obvs. volume-leveling makes it much much worse.
I'm guessing it's an Underpowered Amp with power-stiffening caps that are way too small.
I found photos of the E40-C2 and D24h-C1 motherboards online (because the D1 is so new, it was unavailable) and the caps near the 4 220nH output inductors (bottom left on each board) do look smaller on the D24.
More evidence in that you have to turn the volume up -a lot- when vol-leveling is off, to get any loudness out of the set at all.
And when vol-leveling is on, it seems like too much preamp, into not enough power-amp, into small speakers== bass frequency distortion.
I A/B'd this against the E40-C2 and the E does not distort. -Funny b/c the speakers are the same width & only about ~1.25 inches longer.
I emailed Vizio, but I'm sure they'll just ignore it, instead of making an improved Rev.2 board.
The only temporary fix seems to be going into EQ and turning the 100Hz and 300Hz bands all the way down to -12.
So, fine I guess. With some compromises. The SmartTV functionality will be better than the 24" Samsung 4500-series.
If you don't need/want any Smart-functionality, maybe the regular 24" Samsuing 4000-series might have as-good/better picture and possibly better (at least non-distorting) sound. -If you can put up with 720p.
