A 50Hz country question about the new Dell LCD screen and in fact most fixed 
pixel array displays (PDPs, etc) for home theatre or even notebook PCs - 
they all have a single nominal 60 Hz vertical rate - only !!!

So is this the reason occasional picture stutter might be seen when showing 
25 and 50 frame per second video - or what mechanism/process removes this 
and does this make these type of displays absolutely OK for critical picture 
evaluation of material that may involve temporal artifacts (particularly if 
trying to play out of a hi-grade PC GPU)?

Maybe Jeroen or others can offer an answer.

Specs for the Dell (including scan rates) are at

And at higher resolutions? Like with Dell's new Apple cinema display



Aren't those cards intended to be used with rgb sources aka personal
computers... Of course they are a great match for any HD HTPC, playing
YCbCr, instead of converting dvd source's YUV to RGB.

Though I just read that Nvidia's new h.264 decompression accelleration has
an edge on ATi's, allowing lower spec cards to accelerate hd signals,
whereas ATi's relies on a certain number of pixelpipes to be present, so
only the high-end cards can provide sufficient accelleration support.

It is said that MS recommends ATi graphics for Vista, due to better driver
support. So no clear cut pc graphics leader at the moment.
