Excuse me, but I didn't understand your tests. I'm not an A/V expert.
- With Imprex at 'Standard' with contrast and other options at medium or even low, I did notice some dulled or clipped blacks and whites with AVS HD 709 test patterns. After some back-and-forths with video clips/samples, I'm finding the settings below more pleasing. It isn't easily noticeable as Imprex's effects in Q5/Q10 Pro are more subtle that previous gen, but paying close attention to black areas of videos, blacks seems more/deep black, and with whites, not blown out, and sharpness not tad edgy looking
- With applying all 3 of the user/forum suggested settings (linked above), I can get proper black and white levels. PQ looks great (a little better, more natural) with samples and movie scenes
- The picture settings that worked best for me using AVS HD 709 test patterns were brightness at 53 and contrast at 43 (so, little different from @BigPines'). This will likely be a little different for everyone in their own home viewing environment, and also depend on which display (and at what settings)
For above, in testing with my Epson 5025UB PJ w/a Da-lite HP 2.4 gain screen, in a light-controlled room, I used the THX @ 6500K preset PQ option.
The real problem is that not all users have the necessary skills to find out the proper settings (like you) to really disable the Imprex Engine. **HiMedia MUST implement an effective "Imprex ON/OFF" switch that can 100% disable the Engine without added difificulties**, that is, without modifying any other setting. IMHO, the current implementation of this switch is not reliable nor intuitive. For example, when I turn off image enhancement on my Panasonic Blu-ray recorder, the image is shown AS IS. I don't need to change anything else.
A Big Thank you for your efforts
