HT4 not scanning files

The description that you gave about it looking like the brightness is turned up too high might describe what I'm seeing. Or if the contrast was turned up too high.

 

@Markswift2003 I just got home from work and set the Zidoo to 16-235. My projector was professionally calibrated and the Brightness is set to 51, which looks great on all other sources. I just lowered the Brightness down to 38 while watching an HDR demo clip, and the picture looks perfect. So for some reason, when the Zidoo is set to 16-236, it makes the picture way too bright causing the blown out look I'm seeing. This isn't the best way to show it by using my iPhone camera, but you can see the top image has deeper colors than the bottom image. The top is Brightness set to 38 and the bottom 51.

 

Here's the EDID file.

 

Firstly, the EDID is fine - there's a setting called "Quantization Range Selectable" which is enabled so that's fine - as I say, I've only seen it disabled in Samsungs, but it was worth checking.

As for those images, I know they probably don't give a fair representation of what you're seeing, but changing Black Level (Brightness) isn't the way to do this - you can see blacks are completely crushed in the top image and it's way too contrasty. The bottom image looks way more correct.

What HDR mode are you using on the Zidoo and again, does HDMI Level set to "Auto" fix it?

 

HDR mode is Dolby Vision VS10 Engine for all content. Auto does seem to correct it but how would I know for sure, just using the eye test? It definitely looks better than 16-235. It's crazy that I have to flash the factory image to fix the 16-235 setting after the color space setting breaks it. I tried again setting the Zidoo to 16-235 and then manually changing the Epson to 16-235, and the image is still dull and too bright. What's weird is when this happened before I could toggle between Auto and 16-235 and it would fix the issue, but now that doesn't even work. The only thing that fixes the issue is a flash of the factory image and never change the color space settings.

 

I'm starting to think I may just have a lemon?

 

Something else is going on.

You said above

So let me ask again, does setting HDR to Auto fix it or not?

 

Yes, to my eyes Auto gets things back to normal but you and a few others have said 16-235 is the proper setting, so now I'm obsessed with that setting working so I know 100% the image is correct.

 

Ok, leave it on Auto. Simple.

Auto is absolutely fine. The only reason that I advocate 16-235 is that it sets the value discretely but there's something odd in your setup that I can't fathom that means 16-235 doesn't do it.

Let me ask another question - what if you set it to 0-255 - Does that look correct and does it look the same as Auto?

 

0-255 looks like 16-235, light colors and too bright. Which do you think would give me the best chance at having the proper image, setting it to Auto, or reflash factory image which I know gives me back the 16-235 option, but then I won't touch the color space option and I'll leave them all on 8 bit instead of changing to 10 bit?

 

Ok, well that really shouldn't happen - I'd go as far as to say that 0-255 can't look the same as 16-235 and one of them must look like "Auto" because there are are only two settings to choose from. I'd love to be there and see what on earth is going on here.

If all was working correctly (and the display is set to 16-235) then setting the Zidoo to either Auto or 16-235 would produce the correct image. Setting to 0-255 would crush blacks and look too dark and contrasty - much like the top image in the pic you posted above.

I'm not sure, but above all else I always say trust your eyes. If Auto looks correct then leave on that and forget about it. As I say, there are only two settings - one will be right, one will be wrong.

 

I'm just baffled as to why a few weeks ago when I had this issue, a simple toggle between Auto and 16-235 would fix the issue, but now that doesn't work. 0-255 and 16-235 definitely look the same which is very strange.

 

If you set HDR to Highest Rec.709, how is the behaviour of Auto/16-235/0-255 then?

ie - is it Auto/16-235 good and 0-255 bad?

 

With Highest Rec.709 set, Auto looks good and both 16-235 and 0-255 have that washed out look. Neither look like Auto.

 

Ok, this is getting weirder.

So let's eliminate the Custom EDID.

Turn Custom EDID off, reboot the box, then set HDR to Highest Rec.709 and try Auto/16-235/0-255 again.

 

In the meantime, here's the Wireshark between the Zidoo and my PC.

 

Ok, so that's weird too.

There's no querying going on at all - the only way I can replicate that is to switch off "Automatic uppdating sources"

Pretty much as soon as I switch that back on, the trace fills up with library queries.

So yeah, your Zidoo isn't talking to its sources and assuming sources are setup in HT and "Automatic updating sources" is on, I have no explanation as to why.

 

Your setup is an enigma!!

 

The PC and Zidoo are both on a 8 port gigabit switch. Does that matter? The switch is connected to the main router.

 

Also, I decided to take a chance with flashing the factory ROM and it flashed just fine. So now I'm starting from scratch with the factory firmware and no custom EDID installed. Not touching any settings, Auto crushes the blacks, 16-235 looks right, and 0-255 gives that dull color and too bright look. That's with the HDR setting set to Auto. What firmware do you suggest I use ?
