Crappy viewable angle with monitor in the office

I have DELL 1907FPc and 2208WPF monitor in the office. But, when viewing at portirat mode look TERRIBLE. 1907 FPc only got 160 degree of viewable angle. Same 160 degree for the 2208WPF. Hopefully my new 2408WFP will do a much better job. Otherwise I will be very very pissed.
