Looks to me like linear light has less noise, and better preserves edge detail.
edit: Linear (pure power) also has the best overall luminance match.

The results are all over the place... Gamma for cyberbeing, Power for 6233638, Rec.709 for nevcairiel, sRGB for iSunrise, I like sRGB with 2.2 or Power with 1.92. The wanted power values are also ranging from 1.92 to 2.60.

PotP won't let me select the image source filter AFAIK, it'll always be "Image source". It would be most amazing if you could nail down the name of the still images source filters used in PotP & MPC and provide a picture-viewer mode in mVR that would kill all black frames(that keep coming and going more or less randomly, making it very hard to use) and allow to setup a custom profile with 256 neurons all the way
I also much prefer GL in all the screenshots you posted(at 100% scaling) but then again OC is not my thang |

Did you reboot after using madLevelsTweaker? If that doesn't help then something else is going on. Make sure you disable (and set to neutral values) all options in the GPU control panel like color/gamma adjustments, dynamic contrast, skin tone adjustments, etc etc. Maybe a driver cleaning and reinstall will help? I'm not sure what else to suggest... |

To all users on Windows 8 : does it work for you? I can't be the only one... I guess. It's really weird because my setup is very close to 6233638's setup. Quote:

Gamma is brighter than the original. BT.709 2.2 is darker than original. The rest are much, much darker. Quote:

1/0.45 looks best to me from the images you have posted, and not by a small margin. The others are all too bright. I think it's very difficult to judge on larger screens, because the dithering is not as effective there. What are you calibrating your screen to? BT.709 content should be viewed using the BT.1886 transfer function (which becomes a flat 2.40 gamma on high contrast displays) and never the BT.709 transfer function, which is intended for capture, not playback. |

Yep,
Now the question remains what would madshi do about it with madVR. There should be a Standard setting (don't touch if you don't know what it is). And Customization options for more advanced users or ones that read the thread. What is the standard gamma curve of modern LCD TVs?

Isn't dithering the final step before rendering? In that case, shouldn't it (luminance) map to whatever the device is calibrated too? Based on the settings in the calibration tab.
Otherwise, wouldn't it be best to map back to the source profile?

turbojet,
I think for the last few driver versions Nvidia forced 0-255 with 60Hz, and 16-235 with 59Hz on HDMI output. So if you set madLevelsTweaker to full range and refresh rate to 60Hz you get double expansion (clipped black and white). Or changing to YCbCr444/RGB changes the range too in NCP. It can be my display so don't take my word for it, test yourself.

1.2/0.51 = 2.35 Though newer standards based upon measurements of mastering-grade monitors (BT.1886) have moved this to 2.40 rather than 2.35 Displays sold today are far more likely to be around 2.2 gamma than 2.35 out of the box though, which is why I would suggest using that value instead if nothing is specified. |

Clean driver install had no effect. The 250 is connected via s-video to a 59Hz crt with latest drivers. A 650 (327 drivers) is connected to 24/48/50/60Hz LCD via hdmi. I'll go check to see if there is a difference when switching refresh rate on the LCD.

Depending on the content I view, I have several choices to go with. I know that Rec.709 is only intended for capturing/monitoring, but BT.709 still is the closest here. BT.1886 didn´t work out to well for me last time I tried. Then again, I´m not using DispCal or the ArgylCMS, I´m using the Eizo Colornavigator for this.

If the 3dlut doesn't contain that information, then I agree. Quote:
In essence, I now see excellent shadow detail, with actual blacks. Previously, I would either have crushed blacks, or grey shadows. It was impossible (for me), to get the display to show a pure black with shadow detail.

Things might be different if there were proper gamma settings/10 points white balance in my F5000 Sammy TV but only their "6" serie does that and anything higher that their "5" serie can't do BFI without FI duh...and I think I like slightly crushed blacks anyway. Definitely not going back to Argyll, especially after whining to Graeme for the Nth time about BT1886 looking funky and him sending me yet another possible bug fix....20 mins of flashing colors to end up with a crappy gamma curve are beyond my patience.
