I’ve got a couple issues with the U5 3D capability some people here may be able to advise on. I have emailed support as well and saw this in the reply so trying here as well.
There is a blue cast over the image in 3D mode. This could be the sync pulse but I don’t recall it being like that originally. It looks better through the glasses (Boblov) but there is still a light blue cast in the dark areas
There is often tearing in the videos usually noticeable in panning. This appears as a horizontal line that is usually at the top of the screen and breaks the 3D. This is playing via PC but I believe I had the issue playing on the machine directly as well though I might need to confirm that. I’ve tried various settings on the projector in the hope it can remove that but so far it persists
