The Intel® HD Graphics are capable of supporting 24Hz, 30Hz and 60Hz.
"By testing, i know i can't output 1920 x 1080 at 100hz-120hz. ( maybe possible ?)"
As mentioned before Intel® HD Graphics are capable of supporting 24Hz, 30Hz and 60Hz, you will not be able to reach 100Hz or 120Hz.
"But we imagine the motherboard have DisplayPort, you think i can ? ( need DP to DVi adaptor)"
This is the same scenario, your graphics controller will not be able to reach it.
