Good idea on factory reset, but I don't think that will fix the problem. If you read the vw60 tweak threads, you will see some of the people with the problem were expert calibrators intentionally using non-standard GAMMA curves to try to reduce the issue.
One guy went as far as hiring Tom Huffman to fix his issue (see Jcastle's post http://www.avsforum.com/avs-vb/showt...8#post19969128
), and Tom told him he ended up needing to pair it with an external scaler type device to get the problem completely calibrated out. Although he may have potentially accomplished it with other means as well (Image Director + Service Menu).
This is still a good projector, just a bit frustrated with this issue, seems every projector has some kind of issue though.
One guy who bought the vw60 new, exchanged his vw60, and reported that a different projector with a different build date still had the problem.
I don't doubt that it can be calibrated out, but it won't be easy.
I used the spears and munsil patterns, my problem is not brightness / contrast.
I feel like I am repeating myself a bit from earlier in this thread, but oh well, I know some people don't have time to read it all.
You can watch hours of content without EVER seeing the blotching problem, and then in certain movies, it will all of a sudden show up dramatically and consistently. It will be SCI FI movies that have the most problems in general. Make sure you watch some dark movies with uneven lighting. An example would be a concert with lights shooting across the screen, a TV series like Stargate Universe, a rocket taking off at night, or a movie like Next or Dark City, there are more examples in the thread.
None of the content above is even guaranteed to show the problem on your unit, it will possibly vary depending on the unit overall to what scenes you see it in depending on your gamma curve.
Note that the issue is usually NEVER
visible from any of the content on any of the test disks (HD DVE, S&M, etc...). There appears to be a specific set of factors that must all come together on the way a movie was filmed and the lighting in order to exhibit the issue.http://www.avsforum.com/avs-vb/showthread.php?t=1134941
Note that although the above thread speaks to the issue, the VW60 tweaker's thread below has much more detailed long-term information on the issue at hand.http://www.avsforum.com/avs-vb/showt...0+tweak+thread
