Debating between two monitors to use as an external with my MBP. HP LP2475w & Dell 2209WA. HP is a 24" H-IPS panel with 1920 x 1200 max resolution. Dell is a 22" e-IPS panel with 1680 x 1050 max resolution. The Dell is half the price of the HP. My concern is the lower resolution on the Dell. What difference is there with the lower resolution of the Dell vs the HP monitor? Keeping in mind of course that the Dell is also 2" smaller than the HP. I'd be using the monitor for extended web surfing, writing for long periods in m.word, and video editing.
