PAL capable LCD monitors - how do they work?

[Planet]

In the past few months, more and more PC monitors feature SDTV functionality. Like this one here, which i'd like to buy in the not so far future: Samsung 2032MW. The intended usage is as PC monitor, for PS2 games and eventually PS3 games. I don't expect any problems with PC or PS3, or even PS2 games that support NTSC, but i am a little sceptic how good PAL signals look.

The vertical frequency of the display is 56 - 75 Hz (just about the same with all PC monitors that can handle SDTV). How is PAL (50 Hz) displayed then? Some kind of pull-up to 60 or 75 Hz? That would probably cause jerking, which would prolly be quite visible in PS2 games.

Can anyone enlighten me here, maybe with some personal experience? I'd love to hear that there is no real problem, but i'd rather face reality even if it hurts. And no, i do not own a decent PAL tv set (mine is old and even smaller than 20") and i do not intent to buy any "real" HDTV soon.

"How is PAL (50 Hz) displayed then?"

1 interlaced frame every 50th/sec there's no conversion if your displaying a pal signal on a pal monitor

Now how does that apply to a monitor which updates its screen at least 56 times per second? Not to mention deinterlacing...

would it de-interlace ?
or just refresh the pixels that have changed ?

there's a SCART connector on it.. cool!

wouldnt supprise me scart is quite popular in europe my tv has one, my dvd player has one, my digi box has one

Yep, in europe you can find scart connectors on just about every video related equipment.

I just came up with an idea how they might have solved the problem (not backed up by anything substantial though). They might deinterlace 50 Hz PAL signal to 25 progressive frames and then display them in 75Hz over 3 cycles each. That should be jerk-free, though i still hope to find something of a more in depth technical analysis before i buy.
