Hey Im in real need of some help. Two weeks ago I went out and ordered a Samsung 42W5HF. Today my new telly arrived and I felt real cool.......got everything built up and plugged in................then I realised the model number is 42W4, not 42W5. Its still the 100HZ version but can anyone tell me any noticeble differences? Dunno if I can be *rsed taking it back if there isnt much of a difference, probably just demand some money off. Any urgent help or advice would be great as Im gonna phone first think in morning and open up a can of woop ass!!
