Not sure about the 2014 models, but the 2013 M651d overclocks (PC's only) to 120hz at 1760x990 and any resolution below that (1600x900, 1280x720, etc); and can OC to 108hz, 109hz if the stars align just right, at 1920x1080. The set also downsamples up to 3840x2160 at 37hz (44hz at 1080p timings) and beyond (6000x3375 at 22hz). 3600x2025 at 42hz (48hz at 1080p timings). 3200x1800 at 52hz (76hz at 1080p timings). 2560x1440 at 81hz (103hz at 1080p timings). And so on.
Also, just to clarify to everyone including whoever did the M651d Cnet review last year, the M651d is a true 240hz panel because even when refreshing at an actual 120hz INPUT refresh rate, there is still Frame Interpolation if it is set to On when not in Game mode. The maximum input refresh rate is 120hz, and the maximum panel refresh rate is 240hz as it can & does refresh at a TRUE 240hz when using 120hz input with Smooth Motion set to On. Confusing, I know.
The M651d also does as low as 19hz PC input, 23.976 is available as a true refresh rate (it also does an excellent 3:2 at 59hz).
The M651d also has a Game mode that does indeed allow you to disable all post-processing and internal processing, decreasing input lag and also eliminating the "soap opera effect", although IMO setting Smooth Motion to Low decreases judder & eye fatigue without making video appear "soap opera-like", but to each their own.
Not sure if this info helps you or not, but the M651d is the only Vizio model we've played with. I would imagine a 240hz 3D panel from the same company would be comparable to most of the above features, but if not I wouldn't be highly surprised.
ALSO, almost forgot to mention, the M651d is also Chroma 4:4:4 capable. Pretty relevant if you're planning to use a TV as a monitor.

It seems to improve the picture in a dark room but not in a bright room. Any other experiences?
I have it set to Off after viewing/testing on my M651d. I use the opening scenes from Alien for black level and color "testing" and, from what I noticed, when a camera pans slowly from light-to-dark or dark-to-light images, the Active LED Zones setting seems to lag behind and cause odd backlighting effects. Basically it brightens or dims the backlight a half second too late. May not be noticeable to all, so YMMV, but I'm leaving it set to Off.

(they might not correlate exactly, but they settings definitely seem to be an improvement over the default settings. After living with them awhile I tried going back to the default settings, but it was just way too hard to look at. With the cnet settings I'm getting finer shadow detail and much less eye fatigue. So I'll keep using them until someone comes up with 11-point White Balance settings for the 2013 models):
[Gain amounts for Red, Green and Blue]
5%: 10, -1, 1
10%: 16, 8, 39
20%: 3, 1, 24
30%: -8, -6, -7
40%: -24, -23, -6
50%: -48, -39, -31
60%: -50, -50, -36
70%: -50, -50, -34
80%: -50, -50, -39
90%: -42, -45, -50
100%: 0, -10, 0
There you go. Hope that helps...
100% agree with your post. These are an improvement. Thanks for posting.
