Philips 27inch Monitor 273E3L Video streaming issues

HI, can anyone help I have been running a HP 22inch monitor for the last two years with a Nvidia Geforce 61502SE 430 and the picture and video streaming quality has always been spot on, no blocking or flickr.. just perfect.

I have just upgraded to this Philips 27inch and no matter what I try with the settings the streaming is terrible, all blocky and any fast movement in the film its not worth watching.

Any ideas please, is my graphics card not good enough now for a 27inch monitor, its a 5ms response time and I am running at 60htz refresh rate the highest it will go

thanks

Thats a lot of real estate for a 430 imo.

I would recomend a better videocard...something in the $100+ range from either Nvidia or ATI.

Do you do any gaming ?
What are the rest of your comp specs ?

Hi and thanks for replying, I dont do gaming, mainly surfing the internet, movies, youtube, etc

My system is AMD Athlon 64 x dual core 4600 2.40ghz
2gig memory 32 bit operating
running vista

Hope that helps, just been watching some fast action movie footage and the picture doesent keep up with the fast movement, never had this problem with a 22inch screen
