I plan to buy a HP LP2475w but when checking on the More Computers web site I found they offer two different versions with different product codes and prices but seemingly the same specs. Product code KD911AT#ABU is £422.86 and product code KD911A4#ABU is £541.86. Both prices include VAT and the warranty is the same. I emailed HP support for an explanation but they simply said that one is a business model and the other a consumer version but surely there must be a some technical differences given that one costs £119 more? Any ideas?
