Help me on a LG F900P monitor and its BNC conector...

[megateto]

Hello there¡

I am currently thinking about my new computer and among the things I am planning to get, there is a new monitor.
I am working on my PhD and I don't have a proper tv (I have acces to an old Philips 14") to get my gaming fixes (I am a console gaming type of guy). I have money to get a semidecent monitor but not for a tv.

So I thought that I could be done with a monitor which had composite inputs, also taking into account the "fact" that next gen consoles will fully support progressive. I found this lg monitor, downloaded the manual, and came across this:

Video input: Input Form Separate, RGB Analog, 0.7Vp-p/75 ohm, Positive

Then comes a picture showing the back of the monitor:

3. In case of using a separate horizontal and vertical sync signal:
Connect each R, G and B video signals and the horizontal and vertical sync
signal to BNC receptacles on rear panel.

Note:

This monitor does not support the DDC function, if you use the 5 BNC connectors with other types of video cards.

Sorry to bother you (please, do bother¡¡XD), but could his help me to play PS2 480p capable games (I've got a Neoya X2VGA for the Xbox)?

Is it a bad decision to not have DVI input (I hope the new monitor lasts at least 5-6 years)?

Thanks / gracias¡
