Mediaportal EVR renderer output 16-235? (1 Viewer)

You can "solve" the issue by forcing lav to pad the video. But avr will still clip so you actually are in a worse situation youve effectively changed 16-235 into 32-219.

Sure but setting LAV to RGB (and untouched as input) as you mentioned earlier should prevent this right ? LAV should pad nothing at all with this settings as to my understanding

I don't recommend coverting to rgb with lav.

Clipping with your avr but still seeing btb wtw (ie 0-16 is flashing) means youll get banding and your essentially getting a more narrow colour range with less individual steps.

So witch output format for LAV would you take ?
I just unchecked everything and set lav to untouched as well
TV: 16-235 or 0-255
GPU: 16-235 or 0-255
Renderer is automatically set to 16-235.

Additionally my HTPC i connected to the TV directly without the avr.

And BTB still clips which i think is strange .... (brightness is high enough to see it)

So the only way i seem to get BTB and WTW to show up is ticking the setting RGB32 within LAV...if this is not ticked i can change whatever i want .... nothing.
Only thing i do not know is if this is the way it should be or if something is wrong

What you describe is exactly what id expect if you are clipping rgb full. Ideally I'd bypass your avr. If that is not possible or practacal then I'd suggest you do the following.

Lav: tick all boxes and click output 0-255 levels. (Ie don't convert to rgb)
Madvr: tick use 0-255 levels
MePo: uses 0-255 by default.
Video card: use either YCbCr or Limited RGB 16-235 (both *should* work, but i think YCbCr would be better).

TV: turn brightness up high. You should see 0-16 flash. Set black level to whatever makes it look the darkest.

Erm:

What you describe is exactly what id expect if you are clipping rgb full. Ideally I'd bypass your avr

Strange is...as described i did not use the AVR i did connect my HTPC directly to the TV...exactly the same result as with the AVR.

Anyhow i will also try your settings

 

[kiwijunglist]

Wait. So leave it plugged in directly. What settings do you have for all options and what model tv do you have?

 

[rohnfe]

TV is a 2008 Samsung LE46A786... in regards to HDMI blacklevel i have low(16-235) and normal(0-255).
GPU is a GeForce 425m within a ASrock Mini PC...with the normal settings you have within the Nvidia Control Panel
Whatelse do you need ?

AVR is Yamaha RX765...

In case it helps, first I always use the attached 'levels.bmp' to check/set the desktop 0-255 range correctly (the 0-255 should be the visible grey range). Then I use the attached 'levels.wmv' to check/set the video levels (16-235 should be the visible grey range, 0-15 and 236-255 should be clipped).

ramp.mpg should also play correctly (the white dotted lines mark the 16 and 235 levels).
