If it does, then your system is either setup to only work with 16-235, or doesn't properly support full-range content.

So when using EVR, it's best to keep everything at 16-235 to avoid the nasty truncation and banding brought about by conversion to 0-255, right? MadVR presumably doesn't have this problem with the higher bit depth used for conversions, so 0-255 makes more sense (matches desktop graphics).

What I meant is that in commercial content (e.g. films) there should be no meaningful content (if anything) above 235. |

Yeah, I agree with small resolutions it would be nice if madshi implemented a scaling range for the OSD. Somewhere between 75% - 100% I suppose. But then the text would be difficult to read on the OSD so I'm not sure how that would work out.

I have an nvidia Ion HTPC and a Hitachi L42A403 that as far as i know it doesn't support full range (0-255), in nvidia control panel theres an option called video configuration and then i can choose 0-255, do you recommend to set it to full range and madvr the same? even if my display doesn't support 0-255, maybe i have to force 0-255 with the .exe included in madvr, in Lav video settings do i have to set it to 0-255 too? I'm all mixed up, thanks all for your help.

Set everything in your playback chain to 0-255 and use the included madNvLevelsTweaker.exe tool to force 0-255 if you're using nvidia drivers. Playback chain includes drivers, madVR, receiver, tv and anything else in-between.

My Samsung TV has HDMI level set to Normal (0-255), madNvLevelsTweaker used to force PC levels, nvidia control panel set to rgb output and full range 0-255, madvr output set to PC levels (0-255). Now, should I set lav video decoder to do rgb->yuv conversion to PC levels, or 'untouched (same as input)'. I select 'untouched'; I figure let madvr handle it. is this correct?

0-255 keeps consistency with the range of my desktop and as madshi has previously said, it provides a visually better dynamic range, however I suppose that's something that you would have to see for yourself if you haven't seen a 0-255 playback chain before.

There's no definitive answer. Set 0-255 on all.
Limited is only there for older displays to ensure you don't spread sources to full but can only see limited.(e.g. washed out picture) If your worried about your display or receiver only displaying limited then use a test pattern. Each situation is different since everyone's setup differs. There's no point saying do this because that's what I did. Test patterns don't lie. Sent from my Blade S using Tapatalk 2 |

My htpc is connected via hdmi to my avr/hdtv. I've got a nvidia gpu and when forcing full range and setting everything to pc levels I'm not able to use these btb patterns. I can see one bar with my brightness cranked and that's it. I calibrated on both a ps3 and my htpc and can make my results match so I know what my brightness needs to be set at. But like I said while in mpc-hc I need to know what to look for in these test patterns. If anyone wants to check out the GCD patterns here's the link http://www.avsforum.com/t/1406352/gc...libration-disk |

That would be the proper setup if your TV does not support full-range RGB, and requires limited. But if it supports full-range, it should be used, imho.
