Unlike current DVDs, which use a red laser to read and write data, Blu-ray uses a blue laser (which is where the format gets its name). A blue laser has a shorter wavelength(405 nanometers) than a red laser (650 nanometers).
The smaller beam focuses more precisely, enabling it to read information recorded in pits that are only 0.15 microns (µm) (1 micron = 10-6 meters) long -- this is more than twice as small as the pits on a DVD.
Plus, Blu-ray has reduced the track pitch from 0.74 microns to 0.32 microns. The smaller pits, smaller beam and shorter track pitch together enable a single-layer Blu-ray disc to hold more than 25 GB of information -- about five times the amount of information that can be stored on a DVD.
Take the TV to another location and see if the lines are gone. If you are connected to an antenna, you might need a bigger or better one to overcome the interference.
How can aids like TV movies or computers assist the teacher?
Educational aids assist the teacher to teach the material by presenting it in different formats and helping the students access different parts of the brain. Students learn in a variety of ways, and thus it is more helpful to teach using as many human sensory inputs as possible. A teacher might not be able to take the students to a certain place or take them back in history, so a movie helps bring the setting to the students.
Computers are good in the educational context because they allow for opportunities for the students to interact. Learning is enhanced when the students feel they are a part of something and getting to experience it firsthand. In science class, models are a helpful tool, but they won't have models of everything. However, a computer can model and demonstrate many different things. While it is not the same as things that can be held and passed around, it still exposes students to what is available.
What do you need to be able to decode NTSC ATSC or PAL transmissions for viewing on a computer?
TV tuner card
Oh I had to change the settings on the decoder to send the signal as 4:3 instead of 16:9
How can TV picture improve using the sky plus box?
The sky plus box provides digital signal, so the image quality is good. Combining the sky plus box with a HD box though, can provide enhanced quality image, if the television device can display in HD. A HDMI cable would be also required.
Can you use a 2.5A 125V cable for an LCD TV?
All televisions are supplied with a power cord suitable for the model. If, for any reason, a new cord is used, it is important that you confirm it is correct for the television. The manual should provide the information but if there is any doubt, for safety, ask the advice of someone properly qualified before using a different power cable.
Today's TV's have fans in them to assist in cooling. You may be hearing that. If it's in the sound coming from the TV, then you have a broken ground connection on one of your audio wires or one of them isn't completely plugged in.
Can you use RG 59 on digital TV?
If the interface requires a co-ax cable, then RG59 is perfectly acceptable for video signals. It is not the best choice for arial or satellite feeds. RG59 suffers from high losses and therefore, will not be the right choice for a long run carrying HD signals. If the cable length is more than a few feet, it is probably wise to invest in something with a lower loss if HD is used now or will be in the future.
Why does your TV say signal out of range when you connect your PC?
All television signals are generated line by line to create a complete frame and the frames are refreshed continually. The lines and frames are repeated at a certain frequency. In the case of a television signal, the fields, or frames, are running at 59.94Hz or 50Hz. Computer displays frequently operate at higher field or frame rate. A message indicating the signal is out of range is almost certainly saying that the field rate is above the rate that the television will handle.
To rectify the problem, use the display settings dialog box in the control panel and adjust the frame rate. If it is set at 75Hz for example, try to lower it to 60 or 70Hz. It may also be necessary to change the resolution to an acceptable format. If the television has a native resolution of 1080 line, try to set the computer display resolution to 1920 x 1080 at 50 or 60Hz, That should offer the best quality display and avoids the need to resize the image to fit the screen.
There is often information on computer resolutions in the television's manual. It's worth taking the time to do some reading and that may save a lot of time experimenting.
How do you cut glare out of 52 LED flatscreen TV?
Sometimes tilting the top down will help. That is moving the top of the screen toward you while leaving the bottom of the screen against the wall.
Is a 1080p 60hz LG LCD TV a good TV?
1080p 60Hz refers to an HD signal format and is not a feature of the television. All modern HD televisions sold in North America will handle that and other 60Hz signal formats.
LG has a reasonable reputation for their television products but the only way to properly judge the television is to watch it. When you buy a television, you are about to spend many hours watching it so make sure that you enjoy the images you see.
How do you change language in sony Bravia BX4?
Press the Home key, that's the key below the arrow keys and above the row of three.
The on screen menu should be displayed. Using the arrow keys tab down to the third icon that looks like a toolbox (more like a lunch box) and press the key in the center of the arrows (the Select button). Press select again and tab down to the next toolbox icon (2nd from bottom) and press select. The language selection is the first option (possibly marked 言語 if Google translate is correct) . Select the first option to scroll down the available languages. Can't guarantee English will be one of them, might be just Japanese, Chinese and Korean.
How long can you leave a DVD in a DVD player?
Theoretically indefinitely. The disc is only spun only when it's being read/accessed, so no damage can be done to the player from this side. THERE IS, however, a possibility, that an inserted disc (be it DVD, Blue-Ray, CD or any other type) CAN cause damage, if the drive is, for example, transported with the disc inside, or if the disc has structural integrity issues and is spun (fairy tales of discs 'exploding' inside drives are not so fairy-tale'y after all).
The best practice is to put the disc away when you're done with it. This will prevent accidental damage to both the player and the disc.
What are HDMI splitters, do they help?
HDMI Splitters are devices used to connect HD TV's to certain other accessories, such as video game consoles and computers. They are needed to connect to outside entities.
Will pausing a blu Ray player effect the disc?
No. The only thing touching the disc, is a laser light, at such low power, there is no harm.
I copied this response to a similar question answered by 'A well lit garden' on Yahoo Answers.
"4 ms LCD response times do help in controlling jitter. If you like watching sports, action movies or gaming on your TV, the extra $150.00 is well worth it.
Additional Notes: LCD TVs use a technique called sample & hold. They display a frame (sample) and then hold that frame until the next frame is updated to the screen. They do NOT allow the image to deacy between frames. It's because LCD images do NOT decay that you get motion blur on an LCD TV. Sample & Hold is unique to LCD TVs. All other TV technologies allow the image to decay between frames and, therefore, do not have motion blur and jitter. Jitter, the shaky edges of fast moving images is directly related to LCD response times. The faster the LCD response time, the less jitter you see. 4ms response times do make a difference in the amount of jitter one sees on an LCD TV (regardless of the TV manufacturer)."
_____________
I'm sorry, I didn't feel that you got a 100% satisfactory response. To make a long answer a simple one, the lower the response time, the better it is for you. 4ms is better than 8ms, and 2ms is better than 4ms. I'm sure we're all wishing for the day when we can find a TV with a 0ms response time!

Can you watch UK freesat in Canada?
All television satellite services have a "footprint" which defines the area of land covered by the transmission. The Freesat footprint covers the whole of the UK and it spills outside the geographic area. As the edge of the footprint is passed, the signal becomes progressively weaker until reception becomes impossible.
Canada is quite a distance from the UK so it is very unlikely that there will be any worthwhile signal. However, with a large dish and a good quality LNB, it might just be possible to get a signal in the far Easterly parts of Canada. The only way to find out is to try it, with the help of a good satellite installer and see what happens.
All Freesat broadcasts are in 50Hz format so it is important to ensure that a television will accept 50Hz signals. (North American television uses 60Hz)
What is the Magnavox US2-MG3S universal remote control code for a Sanyo tv?
It is the tv that has the set code. Then you need to program the remote to that. Google the manufacturer and make.
