What phosphors??? Not sure what to choose.

Howdy folks. Discovered your forums while hunting for this info and getting some good help on other topics around here as well.

My question:

Recently bought a Samsung based TFT panel - Hyundai L90D+ - and when I run Adobe gamma wizard I am not sure what phosphor type to pick. I am defaulted(or so it says I have) to HDTV (CCIR 709). Is this the setting I should be choosing? Would be a big help if someone could let me know.

Thanks for your time!
