Ok, just tested my 868i/S3 (HDMI to DVI)
I had to adjust brightness from 50 to 60 on the S3 to see the blackest bar.
With brightness set to 50(normal setting), the right hand bar is barely visible but there. The middle bar is visible, and the left bar is hidden.
When brightness on the S3 is set to 60, all three bars are clearly visible.
Now the question is, is the left hand darkest black bar below black?
If yes, then HDMI-DVI does pass below black.
If no, then how can i test for it?
I did flick from component to DVI, but couldn't see anymore black or white info.:confused:
This bug in HMDI could explain my initial disappointment with HDMI(DVI).
But i must admit to using HDMI/DVI all the time now as i prefer the image.(after lots of tweaking!)
If i'm losing picture info, no matter how small then that's not good.
HDMI-HDMI via a video processor is my get out of Jail card, as this has always been my intention. But it is not fair on those who don't wish too(who have DVI displays etc)
But if this HDMI-DVI bug is true, then you wonder why more hasn't been mentioned about it.
Anyway, the image below is via HDMI to DVI on my 868i/S3.
Brightness set 10 points higher to enable photo etc.http://www.pauldowning.plus.com/images/plugebars.jpg
