Yes. You MIGHT get it to work if you disable all color correction and dithering and use bicubic scalers, but in that case you're better off using MPC-HCs EVR CP instead.

How I configure this now?
I don't have any calibration experience neither hardware nor software ,
I think this new yCMS feature is Overkill for 99% of madvr users.
I'll quote Madshi for this.

From now on yCMS is only for people who have a meter (or who know the exact primary coordinates of their display).

So to sum up:

If you don't have a meter, don't use yCMS. There's no need to. madVR does all that you need in the same quality.

If you do have a meter, use yCMS to calibrate/optimize your display.
yCMS isn't overkill it's what many would consider necessary for optimal quality. You must remember that MadVR is made for a set of users that wish to have accurate colors and quality resizing and thus yCMS falls into the scope of this project.
Only by better understanding yCMS could you appreciate what it has to offer.

i.e. What is the actual process to use madVR/yCMS effectively?
Yes, basically you display a few test patterns (showing specific colors), measure them with a meter, and then provide the measurement results to yCMS. yCMS will then calculate a "correction" file, called "3dlut", which madVR will then use to improve output quality.

madVR adjusts the output color depending on the source content in any case, even if you don't use yCMS. The purpose of yCMS is to repair anything which might be wrong with your display (and which can technically be repaired by software).

Hi,
I have two questions:

First question:
My Toshiba 42XV635 only supports 24,50 & 60hz, so i set madvr to either use 1080p50 or 1080p60. When i play a video with 23.976 fps, madvr choses 1080p60 as the frequenz, but shouldnt be 1080p50 the better choice? i mean the multiply of 23,976 is nearer to 50 than to 60hz.

Seconed question:
If i set my ATI 5670 GPU with 11.5 CCC to Full RGB 4:4:4 output, my Toshiba 42XV635 sets himself to limited RGB 16-235 in the auto mode and even if i force the TV to use full RGB 0-255, testvideos with black cliping in 0-16 from avs show me that it's still no full RGB... Does anyone has an idea why it's still limited and a way to get real 0-255 output ?

thx in advance

Why don't you use 24Hz? That would be the ultimate best choice.

hmm i thought a good multiply of it would make it more gentle for the eyes, I mean it should have a reason that it is a 100hz LCD

It should take that 24 fps and display it at 96hz.

Set the GPU for 24Hz and in the display is a chip to bring it up to 100Hz or so.

alright, that would answer my first question, how about the second? I read some people here had a similiar problem, but as far as i remember they had'nt an option for HDMI full and limited RGB, so i dont see why it just wont work in FULL RGB... The only way i got the cliping test vid to work with 0-16 Black, is when i set the LCD to limited rgb and madvr to TV levels... but that doesnt seem right?

So, what if you set your LCD to Full and madVR to PC levels? Also, make sure to disable any such dynamic contrast option.

Skwelcha, so you've set HDMI to FullRGB and still have clipped B&W? How about to change Black level in TV's Color menu?

@ namaiki, that doesnt help, and the only thing i activated is the 100hz technology. I Still doent get 0-16 in the clipping vid. The onl thing that changes if i set the LCD to Full RGB is that the Black gets brighter, but even with that i cant see 0-16 in the clipping vid

@ Qaq, yes,i dont get the clipping with Full rgb, but i will check that with the black level

I tried many configurations, but like i said, the only way to get the clipping is HDMI set to limited RGB and madvr to TV- levels.

EDIT: raising the black level doesnt help either.

if it's any help, here's the manual in english, on Page 46 u can find the RGB Range settings.

Just to be clear, when you have madVR set up "right", 0-16 should not be visible. What do you see in the pattern when you have madVR set to PC levels, pixel format on CCC to RGB Full, and your display input to Full RGB?

When all is set to PC/Full RGB It's just black no matter what i do. i dont get what u mean with it shouldn't be visible? As far as i know u should configure your brightness level etc. low enough that u wont see these clippings in 0-16, BUT u should see them if u turn the brightness high enough... At least that's what it said in the tutorial i saw.

No, it depends on where you're doing the expansion. In this case madVR is doing it, so you should not see anything below 16 or above 235. If you can see from 16 to 235, you're all set.

btw, which tutorial? I don't think you need to do the expansion with the brightness slider anymore with most modern displays. They will either accept a full RGB signal ("PC levels"), or clip below 16 automatically.

hmmmmmm so you're saying i should force him to use full rgb und set madvr back to pc levels right? but why is my LCD setting himself to limited in the automatic mode? I would say it believs it gets a limited rgb signal.

I don't know, but that has been known to happen. You'll have to set manually to full RGB in your LCD for max quality with madVR, and at the same time keep your other PC applications at max quality.

alright, than i will set it back to PC levels and Full RGB. Still weird, i was setting my LCD up like in this tutorial( http://revision3.com/hdnation/calibratepart2 ) and the Guy in Blue said if u can't see the clippng from 0 to 16 your Range is set wrong... But i don't know enough about Color Ranges to say he's right or it's just a different thing between bluray player(like the guy in the tut uses) and PC output.

anyway, thanks much for help

Is anything like this http://www.tested.com/news/how-to-en...vie-files/329/ possible with madvr. This guide states that hali render needs to be used. Will it work with madvr?
