I had an ISF Calibration Tech come and do his thing with my system:
- Pio 60" Kuro 608, Cable Box, Intel G33 Based HTPC (all connected with a Yami V2700). All looked great!

I've since changed by HTPC HDMI output card from the Intel G33 to the ATI HD4550 (with Cat9.3) and upgraded to TMT3 and need some advice to tweak the seting on my HTPC to bring it back into spec (it looks like the black levels are too dark). I want to make all the changes I need on my PC as that is how the original calibration was done (he calibrated the TV firstly with a signal generator, then finetuned from the Cable Box, then the PC).

Using the test AVS HD 709 files I "presume" I should make changes in the ATI Control Center rather than try to adjust each of the Video Renderers/Apps etc?

I've also set the ATI CC to "Limited RGB" over "Full"

Any advice would be great.

Thanks
