Does the Auto 2.35:1 FW work as it should with the Panamorph Lens?
Is it any less heat sensitive?
Is it any quieter?
The HD81-LV is a progression of the HD81, it's reliability is yet to be seen and
there are issues that carried over from the HD81, such as; poor auto iris implementation, slow source switching, full field blacks still not class leading,
nor is CR.
Vertical offset seems to be the claimed 36%, whereas the HD81, although claimed 36% was only 27%, so I now have to tilt the projector up due to 8' ceiling, resulting in vertical keystone. There is still light leakage, halo effect outside of the frame, out of the box gray scale is not good, there is a large loss of lumens once calibrated to D65, but still at least as bright as an uncalibrated HD81.
Auto235 works well, but can be bothersome if channel hopping. I have not
had any heat shutdowns or blue screens, although the projector did shutdown
once for no apparent reason--probably an HDMI issue.
I do not find the noise to be bothersome in low lamp mode, it is loud in bright
The warranty has been improved to a three year hot swap and based on my
HD81 reliability issues, this is essential. The bulb now has a one year warranty.
I recommend a review of my first post on this thread, which I have continued
to update over the weeks.
