The Geforce driver's INF file formt keeps changed, and I am too lazy to rewrite it for new version. It should be more convenient just to create a "geforce_hdmi_full_range.reg" file with following contents. If the display adapter # is not 0000, it needs to be adjusted. Of course an OS reboot action is needed to make this setting taken effect. Code:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}\0000] "SetDefaultFullRGBRangeOnHDMI"=dword:00000001 To my Hitachi P42A01A, somehow the visible brightness range is increased below 16 and above 235 --- about 3 additional ones at each direction. But I am curious what causes it. If I don't remember it wrong, the visible brightness range has been calibrated just within 16 ~ 235 at least for 0.5 year and I never touch this TV's HDMI settings again.

@pie1394, should that reg file work for everybody, even after installation of the drivers without the tweak? If so, that would be an even better solution than the tweak, but tweaking the inf files before installing the drivers is really painful!

I sometimes used this method when I was too lazy to modify the driver's INF file. The modification in geforce driver's INF file just instructs the installer to do the same action. Such registry's UUID is obviously for display adapter. Yet the display adapter # is not always 0000. In my system there is also the VNC mirror display driver which owns 0001 ID. It was installed after the geforce driver at that moment. Quote:
A fully display driver reinitialization is more possible. The geforce driver version change under Win7 does not require an OS reboot. (Added since version 250?) |

It should do this via NVAPI, so the range changing tool could do the same? |

I think that shouldn't be the case.
You can go to device manager and disable and restart the driver manually there, I haven't encountered any problems with this yet. Also, in order to get WHQL signature, driver installers must be able to stop, replace and restart a driver without having to restart Windows. At least that's what I heard about video drivers. |

Oh my god this new WHQL driver is awesome, no presentation glitches with 24.94 material @ 59.97 and this with all tweak options disabled, no DX11 and without use a separate device for presentation.
edit: No glitches at all for 23.976 material nor for 25.00 @ 50.00 either. Just awesome.

Not this issue, but a looong list of others.
I'm still fighting with the weirdest audio dropouts right now.. Driver wise, with this issue out of the way, i would favor nvidia over amd any day (probably even before)

I agree that it's now finally the way it should have been right from the start. In any case, it's a very big step forward for NVidia/madVR users. When I originally developed the "new" fullscreen exclusive mode many many months ago, I had expected (and announced) it to be the most reliable playback mode, with no frame drops, no presentation glitches, no smoothness problems whatsoever. I had even hoped to get along without any configuration options etc. But in reality, with NVidia drivers, it was less stable than the other playback modes, and required more configuration and tweaks than the other modes. Now *finally* the new fullscreen exclusive mode may finally live up to its original promise for NVidia users. I'll probably ditch all those ugly tweak options in the next madVR build. Which also means that configuration for new madVR/NVidia users will be much less painful than before. Default settings should work just fine now.

Here's a little tweak utility which should be able to tweak NVidia cards to output fullrange RGB without needing to create custom resolutions:
http://madshi.net/madNvLevelsTweaker.zip When using a multi-monitor setup, just move the tweaker window to the target monitor (the tweak is per monitor) before applying the tweak. This utility is also able to undo the tweak. Furthermore it should work without needing a reboot. It does that by restarting the GPU driver. Doing that might eventually make your computer explode, or result in your socks catching fire. So USE AT YOUR OWN RISK. Of course it works fine on my PC. But then, my socks are fire-proof...
