"samsung" is a household name with a valid Tm or (trade mark) for their name samsung. Owning a domain name with someone else's Tm in it is asking for trouble. Now samsung-monitor to me says samsung electrical, hence a clear violation of the Tm for the term samsung.
Now should samsung get wind of your domain, they may choose to "aquire" it for themselves. If thats the case you have 0% chance of keeping the domain. You will either
1) Hand it over peacefully, tail between your legs or
2) Be taken to court for the domain and have to pay $xxx,xxx court fee's and damages.
I hope that explains it good enough for you. In future try to aquire domains that do not violate other people's Tm's.
All the best
