Doubts about the Sony SDM-P234

Yesterday I almost bought the Sony SDM-P234 that was recommended by
toms hardware review, because I found that the price was lowered to $750,
but after getting some doubts I cancelled it.

Does anyone know if this screen will stretch fullscreen videos. Or can I set it
to display things in 4:3 even if I get the black spaces on the sides.

And can this monitor display HD images and videos.

From what I understand High Definition is just higher resolution.
Since this monitor can handle resolutions of 1900x1200, I think
that it should be just fine.

Thanks for your reply.

I just would like to know if anyone has this monitor and is satisfied
with it before buing it. I just don't trust many of the reviews out there.

And if they go out of business for their monitors does that mean that they
won't redem the waranties?
