I have an Xbox 360. For a couple months, I was playing on a regular tube TV. Then I got a 42” LCD TV (SAMSUNG). I hooked the Xbox up to the new TV and it looked better than on the tube TV. But then about a month later, I realized that the switch on the audio/video cord was still on TV. So I switched it to HDTV. It didn’t really feel like I’d changed anything. But I turned the Xbox and the TV on and I started playing. It didn’t look any different :(. What should I do?
