Wow that's alot. I don't have mine down that much at all, I think it's -3 gain and -5 bias. But that doesn't mean anything when it comes to your specific panel and viewing environment.

FWIW I don't even touch the bias controls, I read (can't remember which site or forums member it may have been, but it was one that I trusted) that the bias controls added some funkiness to the low end on a Sony OLED. Now, I'm aware that I don't have a Sony OLED but I followed the same advice and near black just looks 'cleaner' to me on the ZD9. I've tried recalibration using the bias and gain controls, have also assessed someone else's white balance settings that also had a strong inclination towards dialling down the blue (might've been 10k's settings?) but which used bias as well as gain, and in both cases the near black just didn't look right.

I figured like contrast/brightness gain/bias also work together and have to be adjusted if you touch the other.

One adjusts the lower end while the other adjusts the higher end and although they will interact by their very nature I've gotten excellent greyscale and colour temp from adjusting the gain controls with no bias adjustments at all. I do have to use the 10pt balance to correct some squinkiness at the brightest end of the scale, where red is indeed the main culprit, but the bias controls wouldn't greatly affect that part of the signal anyway.

I've never seen values that low on my previous (Sony) TVs either. Those were calibrated by other people btw. I don't know, the picture doesn't look "off" or anything by eye to me and I don't have the gear (nor the proper knowledge for that matter) to re-calibrate.

Actually, the Canadian Dollar has been around the 0.75 mark for about three years now.

So, I popped in Downton Abbey S1:E1 last night, and, to my surprise, forced-DV did NOT happen. I checked my settings and saw DV was turned on. I thought maybe there was a firmware update I was unaware of. Alas, the next Blu-ray I played, LOTR:FOTR EE, DID have forced-DV. Is there any known explanation for this??

They aren't UHD discs?

You have to manually toggle DV output on or off. If it's on, the display will interpret it as a DV signal regardless of the source.

That's precisely what I'm saying. DV was turned on, and yet the LOTR BD was NOT forced-DV while the Downton Abbey BD was.

No idea why it would do that, but you shouldn't really have DV turned on for non-DV content to begin with.

Well, yes, but that's beside the point. Just reporting what I saw, but now wondering why forced-DV is selectively forced.

Your point is moot. Write Sony an e-mail and ask them. That is, if they actually know what they're doing...

Wow, I thought people would be interested in my discovery, leading to a discussion as to why one BD triggers forced DV and the other does not. But I guess it's just not that interesting to some of you.

But I'll take your suggestion and contact Sony, and then keep their answer to myself.

I’m extremely interested with your discovery because when I reviewed the 1100 ES, it came with a beta firmware that automatically detects DV. However, when the producr was released, the auto DV wasn’t there. Even the Sony trainings in Canada, it was mention that the 1100 ES should have automatic DV switching.

^ Thanks for the support. I can add that the S1 BD of Downton Abbey was NOT forced DV but S6 WAS. Haven't checked the seasons in between yet.

Also, no forced DV on SDR files played from a connected hard drive.

Don't punish the others just because I was being an a** :-)
