Nicehash setup for X11 algo

Hi, i am curious if some1 solved , how to set up miner for X11 on nicehash

my setup:
Algorithm : X11
Stratum: Prohashing.com
Port: 3333
username: tomos81
password: a=x11


after purchasing , my offer was dead, because minimum diff for nicehash is 2, and the miner started to mine at 0.25 diff..
so i tested to add to password: a=x11 h=2 (or d=2)?
can some1 help me how to correctly set up?
when i am using h=2 (minimum network diff=2) , no coins are being mined, because the diff is 0.25(dynamic)

i hope you understood, my english is not ok

thanks for suggestions

minimum static diff is .25, if you go vardiff it starts at .25 and adjusts automatically
