Not exactly a boating topic, but... What is the difference between 720 and 1080 - resolution? Which is better - LCD or plasma? If you don't need a wall-mounted flat screen, DLP has a lot of advantages. You can get a huge, crystal clear, picture for a fraction of the price. There are no burn-in worries or loss of LCD pixels. I have two. One is a 50" and the other (new last week) is a 61". The 61" has the new LED technology and slimmer cabinet. That means there is no need to change the bulb and at 55" wide (61" diag.) it's only about 15" deep and weighs about 70#. I got it out the door for only $2200 - about the same I paid for the 50" a year ago. |

LCD has come a long way, weighs less, runs cooler and many say lasts longer than plasma. But if in the end you don't like watching it, then it isn't worth anything. I bet on boats most are LCD. Simple less power/heat and lighter. Resolution? Higher is better so long as quality is good. Me, I picked LCD. |

The LCD's are good, but you have to check the view angle on some of them as they seem to vary, depending on who supplies the LCD panel. I have a Sony Aquos on one boat and it is viewable across a fairly wide angle. Another, made by Toshiba, (I think) has a very noticable washout when viewing at the same angle as the Sony. At home, we have plasmas. Eisboch |

Another somewhat annoying thing about the Toshiba....
It's one of the new models with a fully digital tuner although it still processes analog. When you turn it on a message appears on the screen, saying "Please wait". This lasts for a fews seconds as the tuner apparently "boots" up. Then, if you change the channel with the remote, there is a significant delay while it changes to the selected channel. Screen goes blank and you wait for a bit. Not good for serious clicker watchers. Eisboch |

Rick DT Stands for "Digital Television" What is going on in your case is 19.1 is probably always a digital simulcast of analog 19, 19.2 is the digital national PBS feed, and 19.3 is a separate sub channel that is carrying something such as local events, community access, announcements, weather, etc. When you see "The following broadcast is in High Definition" and you lose 19.3 this is most likely due to the station shutting it (19.3)down to free up the extra bandwidth necessary to transmit in HD. At this same time your local PBS also switches to PBS's national feed which is why you see the same show on 3 separate channels, analog, digital, and HD. Here's some info on DT subchannels- http://en.wikipedia.org/wiki/Digital_subchannel also on this page- |

It's mostly "How to" shows like Cooking, This Old House, .... like that. When you see "The following broadcast is in High Definition" and you lose 19.3 this is most likely due to the station shutting it (19.3)down to free up the extra bandwidth necessary to transmit in HD.

That all makes sense except I don't lose 19.3. It just keeps broadcasting its own thing no matter what the other channels are doing. I knew Hi Def takes more bandwidth though, and that's why it made sense to me when I was told HD broadcasts used 19.1 plus 19.2 simultaneously to get enough signal out. As an aside, analog always broadcasts the HD programming simultaneously but otherwise has nothing to do with Hi Def transmission. Here's some info on DT subchannels- http://en.wikipedia.org/wiki/Digital_subchannel also on this page- Thanks, I'll check it out. Rick |

I haven't much experience with Dishnetwork equipment, but with DirecTV you can set the box to always output in one format (480,720p, or 1080i) no matter what the original source signal is. When you set the box in this manner there is never any delay while changing channels. With the box set to "native resolution" the box will output in the resolution that the broadcasting station uses and you will incur a slight delay while your TV adjusts to the new resolution. The Dishnetwork receiver may have a similar feature. |

Before this thread gets kicked into the archives, never to be seen
again, I just have one more thing in case anybody's interested. I popped down to Walmart yesterday and bought a Magnavox combination VCR/DVD-R with both an Analog and Digital Tuner for $179. But instead of hooking it up to my new SDTV, I hooked it up to an old Analog set I've had for years. And Voila! I'm picking up digital broadcasts and displaying them on the Analog set. And the reception has never looked better! Needless to say, I'm a happy camper. Just thought I'd mention it in case somebody wants digital programming without the expense of buying a new set just yet, with a VCR/DVD-R to boot. Rick |

Until the content gets better, making the picture bigger doesn't make it better. It only means I need to dedicate more space to the TV. TV is not a significant part of my life. I feel sad for the people who think it is. You and I are apparently the same TV viewer type. I gave up on cable because of all the programming I wasn't watching. All I want is the news, a little football, and PBS programs like Nova, Nature, Hisory programs, and some other stuff most people consider *really* boring. I can get all that on an antenna. And more than I have time to watch when I add digital broadcasting. Mostly I watch 14" & 19" TVs. I bought the 27" TV as a concession to my girlfriend (she's high maintenance ya know lol :-^) Rick |
