Monitor difference

Hi,

i own a Dell E198WFPf and want to make an dual monitor setup with an Dell Precision M2400 M4400 E-Series E-CRT Dock Stand PW395, and stacked ontop or behind it an Dell MDS14 Dual Monitor Stand.

so that you have an idea what has to come.

point is, i have an E198WFPf and want to have an matching size screen next to it. but now I've seen an E198WFPv and was wondering it it is exactly the same, because when i go trough the E198WFP series manual, the smaller letter is an model number.

so what is the difference? and is there actually an difference?
