Hola Matadorluis
I do not presume to be able to advice you like so many here - the experts - but I do have something to say if you're looking into Sony SDMHS94P. Maybe you have some specific reason that it has to be Sony - if so then ignore all I'm about say. But if not then consider Viewsonic VP912S as an alternative. Reasons are as follows: highly similar/same panel, more functional design, lower price and better reviews.
Actually VP912S hasn't got much reviews yet as it is quite new, but its brother VP912B has gotten very favorable feedback all over the net. VP912S is the same but with anti-glare coating instead of reflective (912B) and a silver frame instead of black. Go see my thread here "Choosing the right S-IPS.." and the second message there. Plenty of links there for you.
And one extra place to see: In you can find the reviewers liking the the 912B but not so SDMHS94P.
Just a thought. All the best of luck finding the right monitor for your needs
