VHF signals are essentially Line of sight transmissions (LOS). Like all radio waves they are attenuated by objects in their path. Raising the aerial above the level of the interferring objects while still maintaining an integral waveform (Usually using an artificial ground plane or aerials less than 1/2 lambna), reduces the attenuation and prevents distortion of the polarization pattern thus leading to an efficient transmission path.

Lots of flat screens TVs have PIP capabilities. Vizio, for example. However, they need a second source (DVR, DVD player, etc.) in order to use PIP or POP feature. If you are looking for a TV that has PIP capabilities without an extra component attached to the TV, then I don't know. I'm looking for one myself and am not having any luck.

Amazon sells freeview set top boxes, such as the Labgear LABFV300. Argos is another option with Goodman's Twin SCART Low Energy Freeview Digital Set TopBox. Tesco sells the Icecrypt T2400 Freeview HD Set Top Box and PVR.

That depends. If you have enough money to purchase one, then a LCD can be in a garage. If you don't have the money, I would suggest getting a job (full time preferably) and then in about 3-4 months, you should be able to buy one. You probably can get the best deal at Walmart and probably won't have to wait that long. If you still can't get one, then ask yo momma!

Be careful! Many remotes look similar. For me what worked was "0000" -- my remote accepts 4-digit codes, not 5-digit codes.

Yes it will. Juat put it in the middle.

In almost all instances the two screen types* will be defined as "720" and "1080" which denotes either 720 horizontal lines of resolution or 1080. The more pixels there are the higher quality the picture will be, so a television with 1080p will have a higher resolution than a television with 720p.

The letter "p" means "progressive" which provides a higher resolution than if you see the letter "i" which means "interlaced". If you have two televisions, one a 720p and the other a 720i, the television with 720p will have a higher resolution.

*due to standard screen sizes there is no 700p, only 720i or 720p

The very first attempts at creating color television picture started immediately after the creation of first mechanical black and white televisions in 1880s. While French inventor Maurice Le Blanc proposed creation of mechanical color television, it was Polish inventor Jan Szczepanik patented a color television system in 1897, managing to achieve color reproduction by using selenium photoelectric cell, electromagnet, prism and oscillating mirror. Sadly for Szczepanik, this system did not work well and this invention remained unsuccessful.

Successful prototype of mechanical television system came from Scottish inventor John Logie Baird, who after managing to create black and white television set from common materials (bicycle lamps, cardboard, biscuit tin, string and daring needles) tackled the problem of colors. His solution involved use 3 light sources and 3 spiraling discs that combined their rays of primary light to create visible color image. He demonstrated his invention on July 3, 1928, drawing amazement from the crowd that gathered in droves to see the 30 minute broadcasting of music and traditional Irish stories, and even first ever television commercial for Daily Mail in the UK.

There are no TV manufacturers left in the United States that I currently know of, so that just leaves imported products. The problem is with the so called `marriage of computer and TV` in that the TV manufacturers are falling short in my opinion, when it comes to reliability. With today's TV sets, don't expect the thing to work more than a few months without having some kind of technical problem with the set that requires repair or a part replacement of one type or another. For example, may projection sets use a projection lamp that is supposed to last anywhere from 2,000 to 10,000 hours. They are expensive, too, and the average life of the lamp is usually somewhere between 2,000 and 3,000 hours before they start to fail. DLP (digital light processing sets) generally use a projection lamp, but also a color wheel, which is a mechanical unit consisting of a multi colored wheel that is driven by a small motor in sync with the video, displaying one of the three primary colors one at a time. That means that it spins at a very high R.P.M. and can shatter, or the bearings can fail at any given time. Another expensive item to replace. With the LCD sets, some use projection lamps and others use a backlit fluorescent panel, which can fail. And with the projection lamp models, the lamps can also fail as well as the LCD display unit drying out or shattering if over heated. Plasma sets have their own set of problems too, in that it uses a voltage discharge system to put an image on the screen as well as some type of back lighting, either by projection lamp or fluorescent display. Their primary failure is usually found in the video matrix system and/or the high voltage driver circuits. The trend is toward LED (light emitting diode) projection lamps, but I'm sure that until they get the bugs worked out, that'll just be another source of problems. Another problem is that the manufacturers may incorrectly identify the parts most likely to become defective and not keep enough replacements on hand. Of course, too, the parts are propriety of the manufacturers and they also may provide parts for other manufacturers that require replacements too. In other words, the TV industry in my opinion is nothing more than a `balled up mess' So which TV's are the best and who makes the best TV's on the market? Truthfully, until they can build electronics with a greater capacity for dependability and less prone to failure, I'd say that nobody does.....yet. If you want a good TV, the only way to insure that is by buying the extended warranty and keeping it as long as you're able on the TV. A problem with extended warranties, is that TV manufacturers no longer have to maintain a supply of parts for more than a few years, as compared to the seven or eight years retention of the past, and you may find that after as little as a year's time, parts are no longer available. That's the good point as far as the `repair or replacement` warranty is concerned, and why you should buy one. The bad point is that the extended warranty period will run concurrently with the TV manufacturer's product warranty, so you're putting out money to have your TV covered twice, for the first year or so. Then again, you really, really need to do your research on the extended warranty terms and conditions. Some will only allow you to renew two or three times, regardless of the length of the warranty contract you choose. In other words, which is better: Three two year extensions or three three or four year extensions? Here's a couple of things you need to know, too. The displays on the new TV's are allowed to have `bad pixels' (bad spots) which can determined by the manufacturer, either by the number of bad pixels over the entire TV display, or by the inch or millimeter. The percentages can be quite high, so I'd recommend that you have the TV set unpacked at the place of purchase and that you inspect the screen display area thoroughly, before you take it home or allow it to be delivered. If you don't, and it falls within the allowed "bad pixel" count, you're stuck with it. And believe me when I say that it will become a big source of distraction every time you watch something. Another thing to realize, is that the stores will use the best picture source for their display TV's. Rarely, will it look as good once you get it home. You can bet they're using the latest technology, but you've got to deal with satellite, cable or off the air antennas. Even if you do have a HD source, something will probably just fall short of delivering the true capabilities of the set. It may be from cheaper connection cables, weaker signal, etc. This isn't always the case, but it could happen. When all is said and done, research is your best tool and self education. It cannot be stressed enough. Use the internet and look at the blogs, etc. concerning your chosen brand and see what others have to say after having owned a set for awhile. And no, that doesn't mean just checking Consumer Reports. Why? Simple. They get a new TV and run their tests, reporting the findings. That's all well and good, but it doesn't give you any idea how long a particular set will last, how it'll hold up to power failures and how long the display will function properly. Your best TV? A damned good extended warranty, from a reputable dealer who hopefully, won't lose their shirt and go out of business any time soon.

1. 1080p refers to the resolution on the image in horizontal lines (in this case 1080 horizontal lines of resolution)
2. 240Hz refers to the refresh rate (aka how often the screen fully refreshes the image) of the display. Hz (pronounced "hertz") basically means cycles per second so in this case the image refreshes 240 per second.

For a CRT, I find 75 hz much better, particularly when under florescent lighting. Since the lights run at 120 hz, the monitor can get into a 'synch' with the lights which creates moire patterns on the screen. Changing the rate to 75 or higher prevents this from happening and reduces eye strain.

LCD screens (flat screens) are not likely to have this issue at all and it shouldn't matter.

NO

There are a few small, portable televisions that have inbuilt aerials. They have been around in the analog days and new versions have digital receivers.

The thing that they all have in common is that they don't work well. The built in aerial needs a very strong signal to be effective. Some people are lucky enough to use them in good signal areas, most others have to put up with intermittent pictures or very limited channels.

If you can, try before you buy and in the areas that you will be using it if you buy it.

a converter box- a special electronic device- is required to accomodate the new frequencies. On is reminded of the so-called Electronic switches- actually a misnomer as these were fairly complex devices- used to turn a conventional oscilloscope into a twin-channel split-screen model. These were made and sold as kits by heathkit.

You must have a video capture card in your PC. A card that will take the signal from your TV settop box (video & audio) and record it on your hard disk. Once on your hard disk, then you can burn it to DVD or CD. You also need a capture software to do that. The software can either come with the capture card or you can buy/download a software from other companies like adobe , roxio, or Nero.

Hi,

The viewing area is the white area on a projection screen.

So it does not include the black borders that surround this white area.

It's called the viewing area because that's the part that will reflect the image
from your projector, so the part you are actually looking at.

I hope this helps,

You record using a program called eyetv. I think it costs 100$ but you can download it from a torrent website like i did.

Resolution is defined as the smallest number of discernible detail in an image.

Spatial resolution is the smallest discernible detail in an image and gray level resolution refers to the smallest discernible change is gray level.

Well this is a job best left to a tv repair shop. Removing the old tube should not be a hard job except I would caution you not to lift the tube by it's neck and you should wear safety glasses and gloves because these tubes can implode (blow up) if dropped. Also it's possible to get a shock on the old tube, one time this happened to me as I was lifting a picture tube and placing it into the back of my car. Lucky that my dad was helping me otherwise I could have dropped the tube. The tube should be discharged before you remove it. The real problem is going to be reinstalling the yoke coil and magnets from the old tube to the new one and then adjusting them so the color is in alignment. If you have never done this before you could spend hours trying to get the colors adjusted right.

Yes. The Blu-Ray's blue laser (hence the name) also recognizes DVDs. But the DVD's laser does not recognize Blu-Rays

If your cable box has a HDMI cable port, buy an HDMI cable to connect the TV to the cable box. The next best alternative is to use a S-Video cable with a pair of Audio cables. The third best alternative is to use a RF Coaxial cable. The last option is to use a composite Video and L/R Audio cables.

You should note that while the TV may be HD capable, the cable box may not support HD so you will have to upgrade your cable box to a HD compatible cable box.
