What's the best way to hook up a hdtv to a cable box?
A Cable box and TV are connected together through a RF cable.
What is the mass of a flat screen tv in kg?
Small televisions (20") normally weigh just four or five kilos. Larger ones are considerably more with an 84" commercial model weighing in at well over 100 kilos.
What is the difference between sharp lcd and sharp aquos lcd?
Having worked in the TV repair business for awhile, I can honestly say that I've had to service very few Sharp brand TV products as compared to the other brands. But to answer your question, the `Aquous' line, is a model series of televisions, but I feel confident that Sharp puts in the same quality for all their products.
Is durabrand tv dwt1304 digital signal ready or must a converter be purchased?
Unfortunatly the Durabrand DWT1905 is not digital ready, as it only has 1 NTSC "Cable" input and a set of Mono A/V connectors. To make it digital ready, you would either need a Digital Converter Box, or a DVD or VCR that is ATSC compatible hooked up to it.
HD LCD is a type of T.V
HD - High Definition
LCD - Liquid Crystal Display
What do you need to watch Blu-ray discs in 1080i?
A Blu-Ray player is the first requirement. To watch the content in high definition, an HD television with an HDMI connection is needed but a Bluray player can also be connected to a standard definition television using the analog connections. The benefit of HD will be lost, but you are still able to watch the content.
What equipment do you need to play Blu-ray discs?
You will require a Bluray player to play a disc. To watch content in high definition, you will need an HD television with an HDMI connection between them. However, Bluray players have analog outputs to allow a standard definition signal to be connected to non HD televisions.
What gives the better picture 1080i or 1080p?
Both 1080i and 1080p have the same resolution. That means that the amount of detail will be identical with either. However, 1080p delivers a complete image 50 times per second in Europe or 60 times per second in North America. 1080i delivers half of the image in the same time, followed by the other half in the following field. It follows that sports and other fast moving images will be better on 1080p than 1080i and that is indeed the case when the two are compared. The problem with 1080p is that it is not being broadcast at present and won't be for a number of years. 1080p required twice the bandwidth and twice the storage space. Broadcasters don't presently have equipment to handle live 1080p content. Most new televisions will handle 1080p but even if it does, sport that is broadcast in 1080i will never become 1080p quality. There is no need to worry though. 1080i delivers some great images even for sport. It is worth mentioning that the other HD standard, 720p offers a lower resolution than 1080 but it delivers a full frame 50 or 60 times each second. The bandwidth is the same as 1080p so the image detail is sacrificed a little for the sake of a faster frame rate. Some broadcasters in North America are using 720p but not all. In Europe, 720p is hardly ever seen with broadcasters all moving to 1080i as their standard.
Best Buy offers two brands at their stores: Dynex and Insignia. Both are apparently manufactored by LG but while Insignia is made to compete with the more known brands: Sharp, Sony, Samsung, etc. - Dynex is made to be inexpensive.
How do you turn up the volume on a lg hd tv 2012?
ok so your going to want to use the lg tv remote control. after locating the remote control, find the button labeled VOL. (The VOL button is on the left side of the CH button -- the button used to change channels) To increase volume, press the top portion of the VOL button. BOOM!
From under 6 feet viewing distance the 41" 1080 looks better than the 42" 720. However it's almost humanly impossible to tell the difference fro 7-12 feet (unless your T. Green or C. Ceslik). If you go above 42" tv size, there is difference although slight.
How an image is formed on TV screen?
When you watch TV, your eyes see moving images. But you are really watching still pictures. That's because the images change so quickly(about 30 times every second!) that as far as your eyes are concerned, what you see is actually moving.
Your television collects electric signals from radio waves sent through the air (or from a VCR or DVD player hookup or through cable wires) to the television's antenna. Wherever the elctric signals come from, the television does the same job with them-it converts them to sound and pictures.
To show the pictures, your television uses a system of many dots, called pixels. Imagine each pixel as a box on graph paper (only much, much tinier!). The television signals tell which box to make red, which to make green, and which to make blue in order to create a picture on screen. When all of these tiny pixels appear on the screen, your brain reads them as one complete image. Tammi
Is the Sony tv Bravia a good tv?
Yes, the Sony Bravia BX35 model television is a good and reliable TV. This product is available for purchase in store and online.
How long can you go with co-ax cable?
There are two important factors that affect the maximum length of the cable. One is the data rate for the signal being sent and the other is the cable itself.
A co-ax cable that costs a few cents per foot will normally not have the same performance as one that is a dollar per foot. In general, the larger the diameter of the cable, the lower signal loss it will show for a given distance. All good cables will have a data sheet that sets out the losses for signals of certain frequencies.
Standard definition video needs a far lower data rate than high definition, so when carrying HD content, expect the signal to fail at a shorter distance than SD. As a very. very rough guide, expect SD to cope with several hundred feet of cable. HD may be limited to 100 feet or less for the equivalent cable.
Satellite and cable feeds use higher frequencies than baseband video and so signal loss is more of an issue.
If the cable is to be used as a satellite down feed for example, it is worth calculating the total cable run and asking for advice from a satellite installer. Similarly, many cable companies can offer advice if cable feeds need to be extended.
What are the dynex tv remote codes for a Samsung bd?
I just bought the Samsung BD-C5500 HTiB and used code 85 listed under Emerson to control my Dynex 40" LCD TV. It does not seem to work for "Function/TV Source" but Power, Vol & Tuning/Ch work well.
How do you set up the convergence on a Sony 43 inch rear projection tv?
Disclaimer: This is a tricky procedure that should ONLY be attempted by someone who has been trained to do this. You try this AT YOUR OWN RISK - both to the EQUIPMENT and to YOURSELF and others around you!
In outline, switch of red and blue (you will find gun switches on the control panel along with the other dozens of contrrols!)
Switch on the grid (there will be a "grid picture" generator built-in) then use first the static then the dynamic controls to get the grid as square and even as possible on the screen.
Next, add the red tube (gun). Using the static position controls first, get the centre of the grid to line up, then thebrest of the static controls to aligh the rest as best you can. Next use the synamic controls to adjust the linearity top, bottom, left right etc - and finally use the corner controls to get those aligned as well.
Turn off red, turn on blue (make sure the room is totally dark - seeing the blue alignment is always a problem). Do the same for the blue.
If you absolutely can't get the alignment right (and remember it changes with picture size and distance from the screen - so don't move it once you're done!) on some older projectors, there are "move the whole picure" controls on the necks of the tubes themselves. BE CAREFUL - you're playing with around 28,000 volts around there!
Hitachi Convergence Added
If the convergence is slightly off try running the manual convergence instead of using magic foucus.
1) Turn the TV on
2) Press Magic Focus to begin magic focus
3) Press magic focus again during the magic focus process to get the "stop" screen
4) While stop screen is up, press STATUS or INFO on the remote control (R/C) to bring you to DCAM mode and
the service grid
5) When you first get in here? I believe red is the selected color by default (it is flashing).
6) To choose other colors to converge, use the following buttons on the R/C:
a) "STATUS" - Green
b) "0" - Red
c) "ANT" - Blue
7) Start from the center of the screen and work your way out on one color at a time. I adjusted red across the
whole screen to match green. Then I switched to blue, and adjusted that to green as well. After you adjust blue, you
may want to go back and adjust some red again? etc. until the convergence looks good.
(a) Use 4, 6, 2, and 5 on the R/C to move the cursor position(dotted lines).
(b) Use thumb stick to move the convergence point color.
How much does a plasma screen cost?

What is the difference between 60hz- 120hz?
Television images are created with a stream of still images. In the US, the stream is 60 fields each second. As two fields are needed to make a complete frame or image, the frame rate is 30 per second. In Europe, the rate is slightly slower, at 50 fields and 25 frames per second. As 30 or 25 frames per second is fairly slow, there can be a noticeable flicker and movement can look jerky as well. This is more of a problem in Europe than the US because of the slower frame rate in Europe. The frame rates were chosen years back according the mains supply frequency in the US and UK. Although this is no longer of any concern, with advances in elecctronics, the frame rates have stuck. Even with the move to high definition, the frame rates remain the same - 60Hz in the US and 50Hz in Europe. All other countries, by the way, follow one of the two frame rates.
The 120Hz or 100Hz displays aim to overcome the flickering and jerky movement by inserting a new field between each of the fields received by the television. The theory is that with 100 or 120 fields being displayed each second, the human eye cannot discern the discrete images and see only a smooth picture. For static and slow moving images, the theory works well but as with all engineering solutions, this isn't a perfect one in all cases...
Each field that is inserted needs to be made up. It cannot be a copy of the previous field because it would result in two identical fields, returning the output to 60 or 50 Hz. So, the new, intermediate field has to be calculated by taking the previous and the following field and working out what the image would be, if there was an original field at that time. It's a process called temporal interpolation and needs a huge amount of processing power. Sometimes, the calculations to generate the new field can get confused and the result is a disturbing judder in some parts of the image. Broadcasters who have to use similar techniques will spend a great deal of money to get the best conversions and domestic televisions will never have the same level of hardware installed.
These errors are rarely visible, but before spending a lot of extra cash on a 120Hz television, spend some time looking at the image. Look for fast pans across football supporters as the camera follows the ball, for example. Also look at fast scrolling text. These are the images that may cause problems. If you are happy with the image you see and it looks smoother than the 60Hz equivalent model, then it's a good buy. If it doesn't look smoother, you should ask yourself if the extra cost of a 120Hz television is worthwhile.
That said, there are many 100 and 120Hz televisions that do a good job. Just make sure you can see the improvement before you splash the cash.
Why don't dual layer DVDs play on my DVD player?
First, I want to know what software you used to burn dvd, what video formats you have burned, the model of the DVD Player,
Which feature of Blu-ray disc makes it suitable for high definition?
Blu-Ray discs can only be viewed on high definition displays. Blu-Rays are named in reference to the blue laser used to read the disc. A dual-layer disc contains up to 50GB of capacity. Blu-Rays have a hardcoat layer on the bottom that makes it more resistant to scratches than DVDs are.
How much does an outdoor HDTV antenna cost?
It can cost anywhere for $25 to $155. The cost takes brand and quality into account. At Walmart, you can get them for a reasonably low price (for the most part).
