Hi. I am looking to buy a good 20" wide aspect monitor and see lots of suggestions in favour of the Dells. I can only find: 29009WFP SP2009W which are TN panels (i.e. low quality), or the 2007WP which is not widescreen. There is also a 2208WFP 22" which is also TN. Are any of the new Dell 20" monitors higher standard than TN? Are any of the above any good? I am looking for something reasonable for photo editing mainly, and I am in the UK.
