I just bought the Advent 27" tv (HDTV Monitor) and I hate it. Picture is bad, and the text from shows is horrible, not to mention when I watch DVDS, it switches from the AV inputs to the Cable. Will the store let me take it back and get a refund>? It's also too big (i have a small room and it makes it looked smaller and cramped). So I was thinking if I can take it back, I would save up for a LCD TV. Around 20" and not too pricey. I did see a Sharp that had an awesome resolution but it was 15" and I want something a little bigger. What would be the best kind to get? I also would like to hook it up to my computer, s would that mean that I would need HDTV LCD TV?
