A co-worker wants to buy a new HT to put in his new house, so at lunch time we went to the local BB and looked for a bunch of components, TV, receiver, speakers, sub, DVD player, etc. When we went to check out the TVs he went over to the 27" HD TVs and was looking at a Panasonic unit when the sales person came over and asked us if we needed help. Since my co-worker wants an HD TV but can only afford a 27" HDTV, he was asking about them only. The sales person casually let my buddy know that if you are gonna buy a 27" TV to be the display for your new HT, it is not really gonna be a TRUE HT. He quipped that it is standard knowledge to ALL HT enthusiasts that 36" is the minimum display that could make a system considered to be a TRUE HT. Is this true, or was the salesperson FOS?
