I haven’t researched the subject of M-Series 3D resolution, but I’ve spent some time looking at XF3D on Comcast (side-by-side) and it doesn’t look very sharp to me. For a source like that I don’t know how much resolution you’re giving up… a factor of 2 horizontally because each side has half of 1920 or a factor of 4 because you’re also looking at alternating lines vertically (half of 1080 each eye)? How about Blu-ray… are those a full 1920 horizontal with alternating polarization?

"Sharpness and Resolution with FPR Passive Glasses
By far the most controversial and misunderstood issue in 3D TV currently has to do with the sharpness and resolution delivered with Passive Glasses. Because they split the odd and even lines between the right and left eyes it’s easy to see why many people (and some reviewers) conclude that FPR technology delivers only half of the HD resolution. Although unsubstantiated it still seems to have evolved into some sort of myth based on hearsay instead of actual scientific visual evaluation. Many people seem to get stuck on this particular issue and can’t get beyond it and think about what is really being seen in actual 3D vision."
"Furthermore, in all cases the small text was actually sharper and easier to read and fine details easier to resolve on the FPR Passive Glasses than on the Active Glasses because of the Crosstalk, ghosting and Response Time issues that reduce 3D image sharpness and 3D contrast in Active Glasses TVs. We also compared the small text 3D visual sharpness to the 2D sharpness by repeatedly turning the 3D mode on and off for each of the TVs and watching in 3D with glasses and then 2D without glasses. In all cases the images were sharper in 2D than in 3D, but the differences were much smaller with the FPR TVs than with the TVs with Active Shutter Glasses. In fact, the small text 3D visual sharpness on the FPR TVs were only slightly less than in 2D, reinforcing our conclusion that the Passive Glasses deliver 3D Image Fusion with full 3D 1080p resolution and are visually sharper in 3D than Active Glasses because of the Crosstalk, ghosting and Response Time issues mentioned above. We show below that it’s easy enough for anyone to check these results at home by repeating the visual tests listed in Table 4."
