- Some plasma TVs require you to plug everything into the unit itself (i.e. lots of cables to run to the TV). Others have a separate box used to "accept" all of the inputs, and only 1 or 2 cables are actually run to the TV (i.e. a lot less cables to run to the TV!). Since the wall that I would put the plasma on is brick...I would opt for the latter. Can you tell me what type of system or connection that is? Would that be a "HDMI" connection? Is there a price difference between the 2 types?
- IF I am looking for True HDTV, is a 1280 x 720 resolution better than the 1024 X 1024? What is the difference, and is the 1024 as good as the 1280 for handling HDTV?
- Can a plasma tv freeze? What temperatures, low and high are harmful?
- I recently saw a cable tv broadcast of a football match on a LCD TV at a friends place. I found the pictures of the fast-paced action to be quite blurred (I suppose this in technical parlance is called "ghosting"). I have yet to watch a sports broadcast on Plasma TV. My question is "would the plasma tv also suffer from the same ghosting problem when displaying fast-paced sporting action"? Secondly, you have, in response to some questions on viewing the TV at reduced brightness levels after prolonged use, suggested calibrating the set using either the AVIA or Video Essentials calibration DVDs. My question is: "is the calibration to be done after the reduction in the brightness level has set in or is it to be done at the time of first installing and using the Plasma TV
- Digital Cable vs. Satellite: Is one of these generally preferred over the other when viewing with a plasma TV? Or are they equally superior? Thanks.
- Are plasma tv's filled with A gass if so when would I have to get it filled.
- I am considering buying a wide screen plasma tv but expect that it will also get a lot of use watching standard 4x3 cable tv. Should I be concerned about the burn in from extended use as a 4x3 tv affecting the looks of wide screen movies or shortening the life of the set? Would any manufacturers be a better choice than others from this perspective?
- I have a JVC GM-V42UG 16:9 format with DirectTV and HD receiver. HD channels come in beautifully and fill up the whole screen. When I play a widescreen DVD, I lose about 1.5" of screen on the top and bottom. I thought the widescreen movies were formatted to fill up a 16:9 screen. Do you know what could be happening? Do I need to just wait for HD-DVD's to come out?
- Is there a general rule for screen size to viewing distance? I am contemplating between a 42" and 50". Obviously I want the biggest possible screen without being too close to compromise the best possible picture. Thanks in advance.
- I was recently informed by a TV salesman that there is basically no difference in picture quality between a CRT with Digital Reality Creation (DRC) technology (like the one that Sony uses in its latest CRTs) and a Plasma TV. Is this true? Also, is it true, as some commentators have said, that a CRT HDTV would have a better picture quality than a Plasma?

The Plasmas which use the separate media receiver boxes use a proprietary DVI cable. Another option is to use a home theater receiver as a video switch and run one set of cables to the plasma. In general, the pricing is based on features and performance, not just the outboard media receiver box.

- IF I am looking for True HDTV, is a 1280 x 720 resolution better than the 1024 X 1024? What is the difference, and is the 1024 as good as the 1280 for handling HDTV?
As with most things, there are always going to be some trade-offs. The 1024x1024 resolutions have a superior image quality for 1080i HD signals while the 1280x768 will be better for the 720p HD signals. You will also find that the 1024x1024 ALiS panels are inferior to most 1280x768 or 1024x768 panels when displaying lower resolutions, 480i, 480p.

- Can a plasma tv freeze? What temperatures, low and high are harmful?
Plasmas have an operating range from 32 degrees to 104 degrees Fahrenheit.

What you saw on the LCD is referred to as "trailing" since the LCD panel can not keep pace with fast action video as found in most sports. That is not a problem found with Plasma displays. Secondly, the calibration should be done whenever the room lighting changes significantly for your serious viewing; otherwise, about once a year or if you notice a reduction in brightness of the display. After the initial calibration, the successive calibrations can be done rather quickly once you are familiar with the process.

- Digital Cable vs. Satellite: Is one of these generally preferred over the other when viewing with a plasma TV? Or are they equally superior? Thanks.
Both are generally regarded as preferred over analog cable. Your signal will vary pending your local service providers. It is known that some digital cable channels are not digital while satellite is 100% digital.

- Are plasma tv's filled with A gass if so when would I have to get it filled.
They are filled with a gas in a plasma state. The gas never has to be re-filled.

You should always stretch a 4:3 image to fill the entire screen on a plasma. Otherwise, you will risk burning in the side bars with prolonged viewing.

This is a question of the aspect ratio of the DVD versus the Plasma screen. The 16:9 aspect ratio of your Plasma screen is equivalent to 1.78:1. Movies are filmed with different aspect ratios ranging from 1.78 to 1.85 to 2.35. The movies filmed at 1.78 will fill your screen perfectly, the others will create the bars on the top and bottom. You can read more about aspect ratios at: http://www.widescreen.org/index.shtml

In general, a 42" can be viewed comfortably from 8-12' and the 50" models from 10-15'. I always suggested going to a store where you can sit and view the screen from your average viewing distance at home if you have any doubts.

A CRT TV can not hold its own against a plasma tv. Based how each product projects, the image, the Plasma will always look better and have better colors. There is a more detailed explanation of this in the following article: http://www.plasmatvbuyingguide.com/plasmatvreviews/whyplasmatv.html
