I know they are technically correct, because I prompted their inclusion in Avisynth since version 2.55.
Once you have a DVD with proper colorbars, you can use a red filter to look at the screen, and adjust until the bars show equal brightness. This should be the proper red level. Find a blue or green filter, and do the same. Now rgb balance is proper. Finally, adjust the black strips until you can barely see a very close to black color. Now your brightness levels are correct. That would be the basically so far. You can do things with a greyscale ramp and a grid for geometry and gamma. It depends what kind of controls you have available.

Hi
It may work a try!
Are you using the other ATI dongle to send the signal out to the TV?
Does Avysynth have both colors bars test? (NTSC and PAL)
Thanks for your answer

Finally
I discovered that my DSP-295 prosamp can generate some colors bars SMPTE patterns.
So I am able to calibrate my JVC monitor using the SMPTE and blue check protocol.
And my IPS-monitor that is already calibrated with spyder4 and cover 72% of NTSC gamut.
Between the 2 monitors device I have the proAmp and colors correcting devices.

The primary value of a monitor for editing is the knowledge that what you see on it will be what everyone else will see. Broadcast monitors are designed to do exactly that.

When I correct the colors, adjust brigthness, contrast, hue...at the end IPS-monitor and
JVC monitor display are differents. I don't know all about the analog to digital conversion
process...but I can see obsvious differences...
Image seem a bit brighter on the IPS and colors slightly differents.
For the final capture, should I adjust according on what I see on the broadcast or on the IPS monitor?
Thanks
