update: SOLVED
My monitor is back, they were not able to fix it and it's no longer on the market, so i received newer model - and my issue is gone.
Now we won't be able to figure out if it was because that monitor was broken, or FLIRC does not like HP ZR30w.
Anyhow - it works perfectly with HP Z30i.
to mods: may i ask you to add "solved" to the topic name ? :)
