Yes - I'm using Nvidia drivers - now with a 660 GTX before that with a 430 GT and also 460 GTX.
Did you run Levels Checker as Administrator? It's imperative.
Right-click the "madLevelsTweaker.exe" in your madvr folder.
Select "Run as Administrator" (or whatever it's called in your system language - mine's german).
Then a window should ask you , if you allow madlevelstweaker to make changes.
Now you run it in Admin mode.
Another tip: Change your JVC to a display mode that you haven't changed (Brightness and Contrast are at 0).
Project a 0% black field on your screen (download for example the AVS calibration disc from here:
Take for example the mp4 version and in the "Basic settings" folder play "1-black clipping".
If everything is OK with your graphics card's video levels (0-255) the field 16 is the darkest field (=0% black).
Everything below that (15,14 etc.) should be the same black and should look like dark black not greyish (your JVC
can and should produce an inky black there.
And everything higher (17, 18 etc.) should become lighter.
I don't know if you did this, but this is one of the first steps when calibrating.
So this is "normal" behaviour, not just in my setup?
I'm sure it wasn't like that in earlier versions.
And if you are taking a lot of single readings with a normally very quick sensor like
the I1 Display 3 it makes everything sooooo slooooow...
So you think it depends on madvr?
I just want a quick and peeerfect calibration.....
you may want to consider using a Blu-Ray player or DVD player to calibrate with, and deal with the PC configuration once you have a known baseline to work with.
Is there a way to use madVR or the built in image viewer to display patterns with a constant 22% or so APL? From what I've read, that seems to be the recommended way to calibrate plasmas.
I'm using my PC as the image source, as such I'd rather not manually advance patterns if I do not have to (hence why I'm asking if HCFR can generate patterns with a constant 22% APL).
