My HD1 showed a little 'bright' cornering when I looked at it at the dealer. Top left stood a little more out then the others. This was with the projector at it's feet.
Now it's dangling from the ceiling and at my place the screen is now about even. The 'brighter' corners are now below and far less obvious. I guess most of it is now reflected down and less obvious.
Fade to black is a non issue for me, during fade to black it's black. Only if the last light is gone my eyes adjust and the screen shows a very mild glow. It's far less then any projector I have seen so far.
Had to re-adjust the pixel shift again now the projector is upside down. Convergence is dead on no CA in the corners. No dead or stuck pixels.
Only from a very short distance pixels become noticable (<2ft ) Between the pixels I see very thin dark lines with no blending between pixels.
A slight defocus might be the ticket to have no SDE at all beyond a 2ft viewing distance.
Zoom and sharpness + lens shift are a bit fiddly.
Contrast will improve further when the cc filter arrives. PJ is already calibrated through one of the coler temp user settings.
Screen is 2.8 meter wide and gain is about 1.4.
Image is plenty bright. Bright flashes in dark scenes causing me to flinch.
Loudness. I low hum lower than I am accustomed to.
The landscape scenes in King Kong (HD) are astonishing.
Perfect images from only 4 meter viewing distance.
