You're not sending RGB if it's greyed out. Your video card must be set to output YCbCr.

Zoyd, Stereodude, would you speculate why I need to tick the amd video card's dynamic range to 0-255 to avoid reducing the Samsung's brightness to approx. 18 in order to properly set black reference? Is it because I'm not correctly setting the avr's CS settings? Perhaps I need to connect the htpc directly to the Samsung, bypassing the avr?

My goal is to send 16-235 from WMC7 to the f8500 with the fewest compression/expansion events.

Ideally you want your playback program to render video levels and everything else to be pass-thru. That means the video card needs to be set to 0-255 over HDMI so it won't scale.

failing that, I personally would just set the ps3 to output 16-235 as well. I'd rather do that than switch every time.
Yes, to my knowledge there is no adjustable setting available on the Wii U. I thought about adjusting the PS3, which would be fine, but then the cable box would be out of sync.

So, video card = 'rbg full/0-255' rather than 'rgb limited/0-255' for video only use?

Thank you.

Zoyd, thanks again, but is it RGB Full or RGB Limited?


Color space discussion: Calibrate for 0-255 or 16-235?

At the risk of being repetitive, if your rendering program (madVR, etc.) produces video levels from the source then keep the video card in it's default state (0-255) so it doesn't scale the output.

I apologize for the lack of clarity in the question; I'm sure I'm missing something on this subject.


I've set video card output to 0-255.


What is your opinion on the video card's pixel setting: RGB Full or RGB Limited?

Sorry, I don't understand the difference between "video card output to 0-255" and "pixel setting = RGB Full", my video card only has full vs. limited output settings.

I'm sure that must be the case, and is why I said something was probably off on that. but it's very clearly stated as being 16-235 RGB in my video card settings. so since I can't really 'test' it, it says one thing, but appears to be another, I didn't want to state anything with certainty


EDIT: I dug a little deeper in the menus of the my video card, and did find a setting that indicated I was sending out 4:4:4 YPP.


so, now I have a question. in that above setting I found, I can choose YPP, limited RGB, and full RGB. YPP and limited give me identical results, but I don't want limited since it forces me to switch to low. but when I did full rgb, I didn't notice any change either. the YPP/low combo looked the same as RGB/normal.


I also have a tab dedicated to 'video' settings, and in there I can choose between 0-255 and 16-235 independently of my desktop settings. the only difference I notice with these settings, is that if I set to 0-255, the brightness needs to be higher than if I set to 16-235. but it does appear that leaving this at 16-235, it looks exactly the same whether I am outputting YPP or full RGB(from the other settings tab).


I guess what I'm getting to, is I don't see any difference as long as the ranges are matched. for everyday content, I'm assuming there's not a big reason to complicate things right? I might as well just leave the HTPC outputting YPP, and continue to treat it as a video player? it would be worth it if I were doing some photo editing or stuff like that, but since I'm not, shouldn't really matter?


for what it's worth. I'm using a r7 250 video card, and the amd catalyst control. the two settings I'm talking about are 'pixel format' under the 'my digital flat panels' tab(this is YPP, RGB limited, RGB full) and the dynamic range setting under 'color' in the 'video' tab(full or limited)

I'm guessing, what's happening for you right now is:

wiiU --> 16-235 RGB --> tv does NOT switch, still on normal(0-255), you have mismatched settings.


that's why I say the two solutions to avoid having to switch each time, is to either set your ps3 to 16-235, and the tv to 'low', or if you could set the wiiu to 0-255. the cable box 'should' work automatically regardless of what setting you have for RGB inputs, because the YPP input will automatically go to the correct 16-235.


this is how I am able to have my PS3 play games at 0-255 and blurays at 16-235 without me having to change anything. the games are sent RGB, which I have set to normal, and the blurays are sent YPP, which doesn't require a setting on the tv(it's automatic).


the easy way to check is to see if the option is greyed out when you are watching cable. if it's greyed out, it's a YPP signal, and you don't have to worry about it.

I believe what zoyd is saying, is that you should set your video card settings to RGB full(0-255), so that your desktop and programs and all that look the way they are supposed to. but you need to fix the settings in your video player so that videos(only) are output in 16-235. where I'm not 100% is if it matters whether they are 16-235 RGB(limited) or YPP. I feel like it would be better if you could get YPP since the tv should automatically switch to 16-235, whereas 16-235 RGB would make you switch the tv to the 'low' setting.


I haven't really figured out how to do this nicely with mine, and since I don't particularly care if youtube videos, and facebook photos are accurate, I've set my video card to output 16-235 all the time. this way there's no change between my desktop and video player, no slow hdmi handshake, and no chance of getting dropped connection(I've had a lot of those in the past with my projector)

Interesting; my AMD 6500 with its Catalyst Control Center has an output setting which I set at 0-255 per your suggestion.

It also has a Pixel format option where one can select either RGB Full or RGB Limited. Samsung's brightness setting to achieve reference Reference black is 47 for either of the RGB settings.

However, using the squares seen in the attachment squares 1, 2 and 3 are visible using RGB Limited, and are not visible using RGB Full. The 0-225 setting is unchanged with either.

Any opinion on why this occurs and if squares 1, 2 and 3 are necessary for video? Does viewing the three squares mean other parts of the space are now incorrect?

My hair now hurts from this. Your hardware configuration is much more challenging than mine and I still can't fully grasp the topic.

I've set the range to 0-255 for the video card, all other settings on the chain are 16-235.

The remaining issue is the pixel setting of either rgb full or rgb limited for the video card. This setting is independent of, and interacts with, the 0-255 range setting.

My player is WMC7, so I don't have the luxury of changing the color space within the application; it's 16-235 or nothing.

Whichever setting gives you the correct black/white points when the display is set to HDMI=Low, including passing above white codes, is the one you should use. Use the brightness and contrast clipping patterns from the AVSHD mp4.

im also using media center, so I can appreciate the frustration of not having many controls. this was the main reason I opted to set my HTPC to the limited range(and in fact forego RGB entirely and use the YPP video format) and just treat the whole thing like a 'video player'.


btw, rgb full is 0-255, rgb limited is 16-235. but chances are, like with mine, the two settings apply to different situations. it appears one setting sis a 'global setting' and the other only applies to video. so my guess is you'd want to set it to rgb limited, but best to double check with the patterns.

This is what I ended up with, and it seems to be working well for all sources. I'm used to the 500M, which can be a bit of a nightmare in this area. I kind of forgot that a normal display should automatically sort out YPP. Whenever I get this thing calibrated, I'll confirm that all is well, but subjectively it looks good...with blacks where they should be and reasonable shadow detail across the board.


Thanks!
