I have recently received a replacement for my launch day PlayStation VR headset, because of a problem with a couple of pixels being stuck on blue screens. When I received my replacement, I immediately noticed how different the mura effect was in the new headset. It was very striking. So now I am very curious, does the mura you see have a pattern to it, or is it random? If you are wondering what I am on about, mura effect is a grainy pattern that can look like a very thin layer of fabric in front of the screen. I should only be apparent on very dark or pure black screens. It is caused by voltage not being completely constant across an OLED screen, which causes black pixels to appear slightly different shades of black. I have attempted to mock up examples of what the options in the poll might look like. These are not real photos of mura, they are just for demonstration purposes: [Random Noise](https://c1.staticflickr.com/3/2571/32820912056_59ae99bf8b.jpg) [Stripes](https://c1.staticflickr.com/3/2820/32047234773_5c128cd8c6_z.jpg) [Grid](https://c1.staticflickr.com/3/2399/32861987005_ae05d51490.jpg) [Another Grid](https://c1.staticflickr.com/1/668/32047235533_6a1cbb57c9_z.jpg) [Clouding](https://c1.staticflickr.com/3/2570/32861987155_03b382812c_z.jpg) They could be more or less intense than the examples above. I'd love to know what you see. If there isn't an option for what you see, or the intensity is very different, please describe. Both my headsets have a production date of 06.2016. If yours have a different date, that would also be interesting to know.
