My first 65" actually got a pinkish tint in the edges that was extremely noticeable off angle, none of the others have done that.
Vignette varies greatly based on the sets i've seen in person. The best i've seen in real life was my old 509 which had none until 3%, and even then it was only half an inch. The second EF9500 has about 3 inches on one side at 5%, and half an inch at 10%. Noticeable in content. My friend's 55 has even worse dark edges. At 5% it has ~5" from the edges that are slightly darker but not totally crushed, then solid dark around 2" in an almost straight line. His white uniformity is absolutely perfect though, best i've seen and better than any pictures i've seen in this thread.
All sets i've seen have had absolutely poor black uniformity, which surprisingly is never really an issue and rarely shows up in real content. It does show up in dark games though, due to the amount of panning that FPS games have.
3D crosstalk is a minor problem on both the 65s I had, I have to sit on a pillow to get rid of it. 3D crosstalk on a 55" I tested was absolutely awful and unfixable, which is why my friend is exchanging it. My friend's 55" replacement is actually coming in today. I will be heading back over there to check it out, so i'll have another 55" sample to look at. If white uniformity is perfect again, there's no doubt I will be refunding my 65 and going with a 55.
In short when getting a new set I would encourage anyone to:
- Put up a 100% white and check for any pink/yellow bands/blobs, any form of this is a defect that doesn't exist on all sets.
- Put up a 5% gray and check for vignette, if it's over half an inch on each side in a dark room, it's pretty bad. Ideally you should have none at 5%. All sets are going to have it at below 5%, but it's not really minor at that point.
- Play a 3D disc that has tests for crosstalk, or watch a few 3D movies. Chances are you will get crosstalk if you recline in your chair, but if you still get crosstalk while sitting dead center then the 3D filter was applied incorrectly.
With these 3 tests you've covered the major widespread defects that are noticeable in real content. Sadly, getting one that checks out in all 3 departments is pretty rare - though I feel the 55" version only has to worry about 2 of these issues.
Yup, you and about 50 other owners. It always seems minor at first, but if it's there, you will notice it in some content and when you do you'll start noticing it more and more.
Yellow band is (IMO) the worst defect on these TVs. If it's there, EXCHANGE before it's too late!
The 3D on all three of my 65EF9500s has been stunning on content (Avatar, Star Trek Into Darkness, Life of Pi) but I have not run any specific test patterns for 3D crosstalk - do you know where to find them? Are they available here on AVS Forum?
p.s. different folks are sensitive to different strokes - I find 55EC9300-like gradual discoloration near white to be invisible on content, while the 'black flames' caused by 3" of vignetting, even if only at 3%, are very noticeable, distracting, and objectionable when watching dark content in a dark room. Abrupt near-white discoloration such as the classic 'yellow banding' pictured on many posts at the beginning of this thread is another story - the abrupt vertical transitions would be easily noticeable on any white content such as hockey, scenes of snow, or the famous bathroom scene from Casablanca...
