You have the option of using cinema black on all modes, but there is no smart led. I use standard for bright room and it's pretty darn black. I'm not doubting vizios bang for the buck. But I've been following both the E and M threads and it seems like the quality control, remote, implementation of apps and software updates, motion handling, etc all still scream budget TV. If they fixed those things, I would consider buying one.
I hate to rain on your parade but the Vizio M series is a much better TV than the Samsung 7 series in terms of PQ IMO. You're going to find that about every professional review is going to back up Mark's impressions. Heck, even last year's M series outperformed the F7100 per testing by cnet. IMO Vizio's error was not comparing the M series to the Samsung UNH8000 as that TV would have been a much fairer comparison. But I guess they wanted to pick on a TV that's clearly inferior but in Vizio's defense the H7150 does cost quite a bit more.
As for motion the demonstrations aligned perfectly with my experiences when comparing the D7000 and M501d-A2R when I had both sets. No I still don't own the 2013 M series as I returned 3 of them (one at a time) due to light bleed issues especially with blooming. I also sold the D7000 as I could no longer take the clouding and flashing lighting issues. Hence I don't have any TV for my bedroom currently.
You're darn right the F7100 has a different version of dimming, it called framed (also known as global) dimming which is video based and it's pretty much worthless as dimming is done to the entire
screen from frame to frame. It does nothing to improve contrast.
Based upon a Consumer Reports' survey on problems encountered by TV owners, Panasonic was at the top and Samsung was near the bottom with Vizio somewhere in between. Keep in mind I think Samsung's results were skewed a bit since they're the first to try out new features but it's not like Samsung is known as a paragon of quality control.
The F7100 has a clear advantage over the M series with video processing. Samsung is simply the best in that regard. It's one of the reasons I'll be holding out for the P series. However that advantage become less meaningful for those who watch little SD content.
After I returned my M series television I thought I was done with Vizio but I freely admit I've become a big fan of theirs ever since the 2014 CES as I was highly impressed with their specs and the early reviews of the 2014 E and M series have pretty much backed the hype. Hey, be sure to check out cnet's review of the H7150 if they review it this year. I'm sure to be entertained as you rationalize how Vizio screams budget TV in comparison.
