If you can then the CB3HD is clipping your video.
I spent a few hours today playing with the Munsil disc and the Cb3HD and the Bryston Sp3 as well. I am using Panasonics Latest TV which is very accurate and when i set the Contrast down to about 35 i can see up to around 250 or so. This is when i drop contrast down to a level that i would never be using for regular watching. I am forcing the TV to display the higher white range but creating an environment that i would never watch a movie in.
When I set the TV to this contrast level to display the higher numbers , this also required me to set the TV's HDMI input setting to a mode called NON Standard. The HDMI input section of every Panasonic TV has a Standard mode which clearly says 16-235 Standard and a Non Standard mode which allows the full range. Once i Set to Non Standard and Jack the contrast all the way down , yes I can see the higher white numbers when directly connected to my blue ray, well up to again around 250. After that you cant see anything else.
I then connect the Cb3HD and or the Bryston Sp3 and Voila , you get the range of 16-235. No question that the Blanca and the Bryston are both only allowing 16-235. Based on what i am saying there are some things to consider. For anyone who has a normal TV / Projector , the ranges on those devices are set to 16-235 because that is what everyone from the Big Display companies thinks is the standard. Of course we can tell Sony and Panasonic and Samsung that they are wrong and I am sure Munsil will back us ,but for what ? The bottom line is even if the Pre Pro passes more range , the additional range does nothing for 99.9995 percent of the world. The Additional range cant be seen by most or maybe all display devices when they are set to normal tv watching.
So what i am asking is this. Are you saying that when your in your normal TV watching mode on your projector and you put on Munsils disc, can you clearly see above 240 in the whites and also below 16 in the blacks ? Can you take a picture of this for us to see ? I have to see this as i am not doubting you but i dont think that is is happening.. Maybe when its in calibration mode you can but for regular watching mode, i dont think so.
Roger Dressler says he can see all 0-255 on his SSP-800 and what i am saying is even if the SSP-800 Passed 0-255, Rogers TV and player would not be able to show that much range. I would love for Roger to Explain to us what he is using for a Display and to also take a picture of the TV showing 0-255 through a SSP800.
I can tell you this. Theta is looking at this for us and they are working on patching the Firmware in the HDMI board as there is the ability to be set all the way open. They set the Board the way the industry advises everyone to set their devices and thats 16-235. Why does Panasonic , Sony, LG, Samsung and every other main stream company set their devices to 16-235 ? This is the Million dollar question. I also believe that if an HDMI controller can pass 16-235 or 0-255 , of course I would think it would be better to Pass 0-255 but why then is the industry doing 16-235?
What needs to be understood is that just about everyones display device can not show outside the 16-235 Range. This is important and people who read this thread do need to understand this. People who want to see how this works can simply get the Munsil disc and try it themselves.
I will keep you updated as to how we progress to be able to open the pipe in the Blanca and I will report this to Bryston As well. Once we get it opened , i will make sure you get the first patch to try on your machine as I know you love this stuff.
I do very much appreciate your involvement but uncovering the real facts of 16-235 is key so people dont get confused.
I would love to see your screen showing 0-255 and also Rogers. From what I understand , Classe Used an older version of a Video card so I am surprised if they can do 0-255 at all.
