Yes. I went to small, then back to medium (default). I tried straps after, and that was very helpful. I will mix it up with the pads again probably... but they are really hard to get on/off and I fear breaking the unit.
The processor unit is very small and easy to lift, so this is totally reasonable. And probably even safer; if someone kicks the cord it yanks the processor and not the HMD!
Nope. It's definitely the HMD itself.
I have gotten the blur isolated to top-right or top-left, depending on positioning. Maybe there's a trick we haven't hit on yet? But like pixel grid, I think blur is just going to be a reality of this device.
Reading further posts, it may be mis-aligned optics. That would be good news since it means Sony can fix it! I like the 3D a ton and a half though, and am willing to put up with this issue if it cannot be fixed... at least right now.
I think it would be prudent to hit the Sony Style Retail store here in SDO to see if their demo units have the same problem. Just don't know when I'll have time...
