Question about HP EliteDisplay E243i

These are the warranty services:
Item: 6478923: 5 years On-Site (239.-)
Item: 10369198: 24 months Bring-In (199.-)

Resolution WUXGA or UXGA and probably the related settings.
As well as 10mm difference in height 351 to 362mm.
This is the specification on Digitec.
I use 4 of the WUXGA and am very satisfied....
