Thanks for all the comments. Interesting stuff. Very nice kit. I'm looking for something about 19" or "20, and preferably without built in speakers. I guess thats hard to find. Main purpose would be PC monitor, which I didn't make clear before.
Samsung LW22A13 has a PC input. Max resolution = 1280 x 720 (nb this is not what is quoted on many retailers websites). Get one for about GBP1000 or so. Plus 2 x SCART (one RGB) separate SVideo, Video, audio plus PC audio, and a regular analog tuner.
Relysis is a bit small then, but at £450 or less, good value, 1280X768 us the usual res for these babies, they're probably all that. You might notice that this is not 16:9, the pixels are rectangular to compensate. Some screens have 'faulty' software, which causes overscan of the image maybe cos of this, but it's easy to run this res. via PC, and it looks fine. If you are a fussy man, you will notice slight distortion of DVD picture from PC, 6.7% in fact. The screen software should take care of this from a video input, but it does this in varying ways from screen to screen. Can't think of a 19" or 20" widescreen, 17" for relisys and the others start at 22". Quite a price hike at this point, but some of the 22" are very fine indeed, it would be my choice given unlimited finance.
I think you can do that, but it makes no sense, the picture will then be 'shrunk' cos of the rectangular pixels. The screens measure 16:9 in most cases, but it's the pixel count which is not. This happens with plasmas too. Moral of story, buy a set with square ones. Like the samsung above, fujitsu/panasonic plasma in 50", and low res 42" if this point is important to you.
