Which monitor?

[geofflove]

I'm considering getting a replacement monitor. I've currently got a 4:3 format Acer 19inch LCD.
This has been fine but am looking to go widescreen to give extra 'working room' to the sides. So two questions...

1) what size widescreen would I need to go for to get a similar height screen as I have now? I guess I could sit down and do the maths but does anyone know?

2) in terms of pic quality what will I get by spending a bit more. This monitor has been ok but I suspect I'm missing some of the more subtle colours that you might see on a more dedicated 'photo' monitor. Has anyone had experience of this transition and care to comment on how much difference it makes?

3) Finally if anyone's gone down this route can anyone suggest some models to consider which give a good compromise on quality/cost. I'm wnating to keep this side of £400 unless anyone can pursuade me otherwise.

Thanks

I use an Eizo, but you might look at the LaCie 320. Its about your price here in the USA, but I don't know what it would cost in the UK.

From what I can see these only go up to 20 inch though..... it's also 4:3 aspect which I what I have - am looking for widescreen

well for widescreen you don't want less than 24" widescreen (22" are poor displays as they're based on TN panels) and an Apple 23" res isn't any better than a 20" (infact @ 1680x1050 you actually have less pixels than on a 4/3 20" @ 1600x1200)
