Sony makes the better picture, that's why they cost more.

Although Sony is often given too much credit, they do not produce their own glass for both LCD or Plasma, they buy it from LG, Samsung or Philips the big three glass manufacturers. As they say beauty is in the eye of the beholder and the most expensive is not always the best . . . trust your own eyes and don't always trust those enamored by brand names.

You're talking about lines of video resolution, or generally, the amount of picture detail.

Of course a 1080 (I or P) is going to offer greater detail, but you also need to keep in mind the original picture source and the system used by which it was recorded.

1080p is a high definition video format. 1080 refers to the number of lines that make up the complete image. The "p" stands for "progressive". A progressive format builds the complete image from line 1 to line 1080.

1080i has the same number of lines but is an interlaced format. The picture is built in two passes. The first pass has all the odd numbered lines - 1, 3, 5, 7 and so on to line1079. The next pass has the even numbered lines - 2, 4, 6 through to line 1080.

Information is delivered twice as fast with 1080p compared to 1080i. Currently, broadcasters do not use 1080p which is found only on local sources such as Bluray, games consoles and computers.

1080i is the main standard for HD broadcasting. (720p is the other standard employed). 1080p is not used for broadcasting at present and is unlikely to be used for a number of years. Broadcasters are still busy moving to 1080i, so expect a delay before 1080p makes much of an appearance. The difference between them is the way the image is created. the "i" stands for interlaced and means that each fram is made up of two fields. One field shows all the odd numbered lines and the other shows all the even numbered lines. If a field is shown 60 times each second, the whole frame is shown 30 times each second. "p" stands for progressive and means that each field carries all the lines of the image. If 60 fields are shown each second, then 60 full frames are also shown each second. therefore, double the data is required for 1080p compared to 1080i. Theoretically, 1080p can produce better quality than 1080i but compression for storage can mean the difference is minimal.

There are several different standards. In general, 4K refers to a resolution of roughly 4,000 pixels wide and about 2,000 pixels high. That makes it the equivalent of four 1080p screens in height and length. Currently 4K is a catch-all term for a number of standards that are reasonably close to that resolution.

A 2 Disc DVD movie can fit on a single Blu-Ray Disc and be in HD which is more GB. The length of a Movie remains the same, but the Blu-ray has more room to add extras besides the movie.

Yes, a Blu-Ray device is an optical reader.

CD's, DVD's, and Blu-Rays are called Optical Devices because the reader looks at the disks using light. The light is a laser.

Just like a DVD, a Blu-Ray uses a laser beam to light up and read the information on the disk. This is like an old record needle running along a record groove and reading the information. However, the laser used by CD's, DVD's and Blu-Rays does not touch the disk. It just lights it up.

The difference between DVD's and Blu-Rays is the colour of laser. DVD's use a red laser light, Blu-Rays use one that is blue. Different coloured laser beams read different sizes. Writing and reading on a DVD with a red laser beam is like using a crayon, a blue beam is like a sharp pencil. The Blu-Ray is an optical device, just like a DVD, but because it uses a "finer pencil" it can put more information onto the disk.

Use the ASPECT button on the remote to make the picture fill the screen. This will not always work. The program was made in the wide screen format and not necessarily made for the aspect of your TV screen.

Plasma screens are becoming more efficient as their designs are improved. Typically, a modern plasma screen will use in the region of 300W although the power drawn is dependent on the image up to a point. A bright image will draw a little more power than a black screen.

Every model is different so it's worth taking a look in the manual for each model. If the question is asked for energy conservation reasons, be aware that turning the television off whenever it is not being watched and turning the power off completely can often save more energy that choosing a marginally more efficient model.

Blu-ray disc (official abbreviation BD and official shortened name is Blu-ray) is an optical disc storage medium designed to supersede the DVD format. The standard physical medium is a 12 cm plastic optical disc, the same size as DVDs and CDs. Blu-ray Discs contain 25 GB per layer, with dual layer discs (50 GB) the norm for feature-length video discs and additional layers possible in the future.The name Blu-ray Disc refers to the blue laser used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.

Blu-Rays can hold up to a maximum of 50 GB of data, which is 5 times more data than a DVD can hold at a maximum

The company's name is NAP, or North American Philips. Well, at least that's the American version of it. Of course there's no longer any televisions made in America, and they are imported from manufacturers around the world.

About 40 watts which is much lower than the old CRT type TVs.

The short answer is , metal antenna elements are tuned by length and diameter to resonate at a electro magnetic frequencies of the tv channels. The vibrating electrons vibrate each other , even over long distance. Some every day examples of this are , electric guitar , the electrons in a vibrating metal string vibrate the electrons in the electro magnet under the metal string, and this vibrating electron energy is connected to a amplifier.

A simpler example is a 'toaster' , the vibrating 'electrons/electric' flowing through the wires in the toaster make the electrons in the wires vibrate very fast and with a lot of energy and this is high rate of friction between the electrons makes heat. Friction makes Heat and light , light is vibrating electrons vibrating at a rate/frequency that you can see with your eyes The same thing in a light bulb.

The resistance of tungsten wire to the to the vibrating electrons causes more friction and this makes heat and light.

Electricity , is in fact vibrating electrons.

The different rates of vibration convey different information. Type of information are in fact , heat or light. Radio or Television or Etc,.

Yes, the company Vizio is a USA company although some parts are made in other countries but development, engineering etc. are here in the USA. As a result, the profits are spent here in America

The manufacturer of the Sceptre LCD panels is said to be Toshiba, OR so I was told today by a sales person at a local electronics store. Sceptre manufactures the other parts.

February 17, 2009. However, most TV stations will have the options of leaving their analog transmitters for a while longer, if they so choose. How long? Not known, yet, but most will probably shut them off for simple reasons of economics.

Modern electronic design and assembly is outside the scope of any home electronics builder. Devices as complex as televisions are beyond the abilities of most smaller electronics companies.

However, a starting point is to obtain a display panel. LCD display panels can be purchased from a number of electronics component suppliers.

Next is the image processor that can take a video signal and convert it into the correct signal format to feed to the display panel. A single board, high speed signal processing computer might do the job.

Add power supplies, a case and a user control interface and you have a flat screen television.

Before rushing out to buy the parts, you must expect the components to cost far more than a standard television. It will absorb vast amounts of time in electronic design, software and assembly and demands a skill set that few people have. The end result is likely to be inferior to even the cheapest televisions around.

Yes.

VGA is a standard video interface that uses red, green and blue signals with two synchronization signals. Component is a different interface and the two are not directly compatible. Some televisions will accept either RGB or component on the same connectors but not all of those have the ability to accept the separate sync signals.

RGB to component converters are available but may of them do not work with VGA signals because of the different line and frame rates that VGA uses compared to brooadcast signals.

Perhaps a better solution is to obtain a DVI display port for the laptop. They can be connected using a USB device and with the correct lead, they will link to an HDMI port on the television. HDMI carries audio as well as video while DVI is video only. They are otherwise compatible with each other. Separate audio will be needed to do it this way.

There are a smaller number of USB based HDMI ports for a computer, They will normally have audio as part of the signal so removing the need for separate links.

It is always worth checking the television manual to see what capabilities the television has before investing in new hardware.
