increasing the minimum of monitor range from 0-255 to 16-255 would place a 16-level bias on the blacks towards whites.
leave it at 0-255 if you want deeper blacks. monitor setting's "black level" on the other hand is a gamma curve adjustment, "High" puts it on a higher curve (brighter) while "Low" puts it on a lower curve (darker). i suggest disabling it entirely if possible, as you want the gamma curve to be as close to the original as possible. ----------- is there any performance benefit for MadVR when used with Nvidia's new RTX* cards? *Turing architecture with RayTracing and Tensor cores. if we're looking at this purely from raw processing power (GFLOPs) standpoint, Tensor cores on RTX cards is 8times more than their regular CUDA cores.

set your GPU to full range RGB and check which setting makes all or at least most levels visible. 16-255 is unlikely to be correct. |

Apart from that the 2080Ti is about 40% faster for madVR related tasks over the 1080Ti. |

of which, the entire RTX series are a tad more expensive than the Pascal cards, so unless they have any sizeable advantage then i doubt it'd be worth it. |

No need to quote my post.
They're worth it to anyone dealing with HDR 4K and 60FPS content wanting to unlock high/very high NGU modes for the most part, the 10 series still represents excellent value for madVR tasks and right now I can't see any point in recommending the new cards apart from the 2080Ti right now unless you want the best madVR performance you can get though the 2080 would make sense if buying new as based on what I've seen so far it's about the same price as the 1080Ti.

Well I can't disable the Black Level setting in my LG C8, and all reviews online recommend to set it to Low anyways. I guess I have to take a picture of my TV later to prove it.

reviews don't try to opimise for HTPC usage.
if you have your GPU at full range RGB. than this answers your question: "Like I said, I then get raised blacks / lighter image." the option with the most "risen black level" is correct. because with a full range signal you can only get a clipped black/whites or correct one(ignoring madVR setting and expecting or defaults). just try my very easy to do test with the image. |

Double check the following again: PC Graphics card set to FULL RGB 4:4:4 MADVR set to 0-255 video player set to MADVR renderer Try these settings as a test but also report your current settings. TV Black level HIGH Gamma 2.2 Brightness 49 OLED light 50 With these settings and using the black clipping pattern you should see a black crush and will probs only see 20+ flashing. report back what you get. Which movie player are you using?

However, my experience with LG TVs, they all behave exactly the same when it comes to RGB - they are better near-black when fed limited range. For example, with my C7 brightness at default 50, using the pattern from https://www.avsforum.com/forum/40-ol...l#post46798617, with a complete 0-255 chain, the first square that is meant to be visible (which is actually the second square, the first square is completely black) is crushed to black, but with MadVR at 16-235, GPU at 0-255, and TV at low, that square is visible. I've had 5 LG TVs over 10 years, and they have all acted like this. |

i've always had better control of black clipping feeding mine correctly, you'll get an extra conversion using limted in MADVR which can degrade the picture in other ways?

If DXVA2 copyback performs better than D3D11 native, then I might go back to DXVA2 copyback and not care much, otherwise I'd still like to be able to use D3D11 native without losing black bars detection, as I shift the picture to the top of the screen for my manual masking (single mask at the bottom of my 16/9 screen when playing 2.35 or 2.4 content) and can't do without it. EDIT: also I forgot we needed D3D11 to get 10bits without FSE, that's probably why I'm using it. I don't want to use FSE unless I can't do otherwise (i.e. in 3D) due to the long HDMI resync it causes here when displaying a menu on screen, so full screen windowed in 10bits is a requirement for me. Unless I'm mistaken on that point, going back to DXVA2 isn't possible.

you'll get a crushed desktop in this config though so web and youtube and other stuff will be crushed too wont it?

it depends on your GPU but i have a hard time to see d3d11 win at all if you care about GPU performance until madshi switches to d3d11 render pipe. i have no proper way to measure copyback cost but for a modern high performance GPU it's not much at all. but using d3d11 even the madVR OSD tells you what it costs.
i still don't understand why you care about decoder costing you GPU performance but blackbar detection is fine when it takes GPU performance. time will tell if copyback cost more or doing blackbar detection on the GPU. even through copyback has other benefits. |

And sure the desktop is crushed, but the TV has lots of presets. I use ISF bright room with the black level set to high, and ISF dark room set to black level low (all other settings kept identical between them, so switching between bright and dark the only difference is the black level setting). Mine is an HTPC so I don't really use it for anything else anyway (I use the TVs YouTube and other apps with ARC). I know you use Kodi DSplayer, and that has the option to display in 16-235 for correct UI levels with a limited>full>limited chain. Last edited by iSeries; 15th October 2018 at 12:58. |
