Hi,
I have the VPL-VW285ES. I have the same issue with HDR material from the ATV4.
I see a post on 1-22 from a user that now has firmware version 8.004 that has resolved the issue. I hope we can get that soon.
However, absent that, I'd like to do what you did - use an Integral 2.
Could you share your settings for the Integral 2? And any other advice you can offer.
Thanks - Rob
