You're proving my point with these statements. You've never seen the problem directly, so you don't have a good understanding of it. I've described it in detail before and I'll do it again: groups of 3 distinct vertical lines that are blue or green or (very occasionally purple). The space between the groups is about equal to the width of the group. The picture the OP posted had a very vague resemblance but was actually quite different.
I did test CMD, Motion Enhance, etc. extensively and found that they had no effect on the problem. Since the lines can be either blue or green under any condition its easy to think that a change made caused it when it was actually random.
This is irrelevant for this particular problem due to its intermittent nature and the fact that it seems to only impact some units not others.
It's completely relevant. You haven't experienced the problem. If you had, you would realize that while it seems intermittent, it actually occurs in response to a fairly specific set of conditions in the video frame. It only appears intermittent because those conditions can appear at different places in different videos (if it appears at all). When the same condition occurs there is a high probability that the problem will occur. My test clip is a good example of this.
There have been people that have reported the first instance of this happening at around 400 hours using the projector. So that supports the view that you need 300+ hours of testing to verify the problem is solved.
You've ignored the bulk of my argument. You're talking about one case for which we don't have complete information. For instance that person may have been on 1.17 and updated to 2.00 when it came out. Since 1.17 does not cause the problem, no problem would show for most of those 400 hours but then would probably show just a short time after updating.
My argument was that in a group of people at least one would see the problem fairly soon and if no one in the group saw it that's starting to be good evidence that the problem is fixed.
Again, I asked you if anyone has been able to reproduce the problem on you had on your projector using your test clip on another projector. No one has chimed in so far that they have. The only evidence we have is that your test clip reliably reproduced the problem on *your* projector. We don't have evidence to the contrary.
So you're in your 70s and that makes you an expert on this problem? I worked for years producing and shipping products, developing drivers, doing silicon validation and such. These types of intermittent problems can be caused by a variety of different factors and until a root cause has been determined, you cannot state what triggers it or what doesn't. You only have experience with *your* projector. You also keep saying "it's a different problem". The way the problem exhibited itself on your projector may differ from others. It doesn't mean it's a different problem. The problem we are describing is where your projector video corrupts into vertical lines and the projector needs to be restarted to clear it. This is the problem. Someone's bars being green is not a different problem. Someone's bars being triggered differently does not indicate a different problem. Being 70 doesn't grant insight into the root cause of the problem unless you've debugged it with a scope and analyzed it enough to actually root cause the problem on multiple units. Have you?
Now you're being offensive by implying that I'm saying that my age (which is 81 by the way) makes me an expert. You seem to pick and choose the parts of my post to respond to and ignore the rest and in this case you're deliberately distorting information. I did mention the years of experience I had and that was the relevant point. If I was the age that I am without the experience then it wouldn't mean anything.
