Best res monitor for watching blu-rays, freeview HD

Hi guys,

I am currently building a new system which will have a blu ray player and also one of these new DVB-T2 freeview HD USB sticks (which can pick up 4 HD TV channels).

Question is what is best resolution monitor to buy?

I have read somewhere that if you watch a 1920x1080 movie on a 1920x1200 monitor, you actually end up with a poorer picture, as the PC has to guess which colours to use in the additional 120 lines of pixels.

Is this true? Am I best to stick to a monitor which has 1080 rows of pixels, or should I go for max resolution as I can afford? As I say, PC will be used mainly for TV card and blu ray movies, no gaming reqd.
