What about Iiyama?
The Iiyama Vision Master 451 Pro is a great 19" Monitor.
1920 x 1284@85hz I think.
1280 x 1024@110Mhz.
But if the iiyama is expensive or you don't like it, their is still Samsung. The 900NF is well respected on these forums.
On the subject of Nokia monitors, I read somewhere that they have really poor screen regulation and power distribution. I am just saying what I have read, I have never used a Nokia Monitor, so I couldn't say whether it is true.
I had a similar choice and I went with the Iiyama because it was cheaper then the rest and it got rave reviews. It looks cool too, with the curves and the handy USB hub. Sony make good monitors too, but many of the British computer magazines don't really rate them saying that they are overpriced and don't really offer better image quality for the money you will be paying. I bet many people on these forums will disagree though!
😉 Most of the UK mags seem to imply that people only buy sony monitors for the brand.
Here is a link to the iiyama, so you can see it:

I'm sure which ever monitor you choose will be brilliant.
Good luck
