Most Framemeister discussion centers around older consoles, but, seeing as I have both, I was curious to see if Wii games look better sending a Wii through the Framemeister or through the Wii U's emulation. Both output at 1080p60, but the Wii goes through an analog component connection to the Framemeister whereas the Wii U stays digital the entire way. Theoretically, this should result in a better picture from the Wii U, but that, of course, depends on how well it scales.
First, some screenshots. This are taken from Resident Wiivil 4: http://imgur.com/a/6jhO2
. I chose these screenshots because they contain text, so they should be better for comparing sharpness.
For the sake of purity, I am using the pixel purist GameCube profile for progressive scan content on the Framemeister. The only change is that I switched it to 16:9. The first and probably most obvious difference between the two is that the Framemeister, using the profile above, scales at a perfect 2x integer whereas the Wii U does not appear to do so (even though it still doesn't fill the entire screen). Of course it is nicer to have a fuller screen, but at the same time, it seems to me that the Framemeister is giving us the sharper picture. Note that I do not have any sharpening on from the Framemeister. However, the colors are pretty distinctly different, the Framemeister having a redder tone to it.

Might be worthwhile to do another one of these tests using a more colorful game. Can give it a shot if there's any interest.
