How to make your mind up a Video Display for Your Home Theater
First of all, don’t assume you need a huge video screen in your media room. If your screen is too large, visual fatigue will detract from your theater experience. A good, but general rule for screen size is to take a screen width that is half to one third the length from the screen to the primary viewing location. You should keep the viewing cone, formed by a line going from your eyes to each side of the screen, to about thirty degrees.
You can use any display expedient and there advantages and disadvantages to each type. Dlp units tend to have better black levels than Lcd units. Lcos units and variations have the tightest pixel structure.
Hdtv
Front Projection:
Advantages
o A front angle set will produce the largest, most dynamic image. With a good projector and screen aggregate the image will be quite stunning, especially when watching native Hdtv content. If you have never seen the photo produced by a good, front angle set up, you in effect should see one before you make any decisions.
Disadvantages:
o Needs ambient light control. You need to control ambient light to get a in effect good photo because a front angle principles cannot produce black. It must rely on the absence of light being reflected from the screen to show black or dark colors.
o You have to have a corporeal projector mounted somewhere. This question has improved tremendously in the last few years as Crt projectors have basically gone away and digital projectors have improved and shrunk to tiny proportions.
o Video projectors are noisy. They need cooling fans and these are loud. Some up-to-date units however, are much quieter.
o The larger photo and better detail pregnancy will allow you to in effect see problems so you need to have capability video sources or the photo will suffer.
o Many of the projectors on the shop are whether business presentation units or adapted from them. business presentation projectors have much different requirements than home theater projectors. The most prominent requirement for business units is brightness. They reduce other doing parameters to accomplish this. Home theater projectors need very spoton color rendition, spoton grey scale tracking, deep blacks, and relaxation from request for retrial artifacts.
Plasma:
Advantages
o They’re thin! Only 3 to 4 inches thick.
o They look great when displaying Hdtv. (most of them)
Disadvantages
o They can suffer image burn-in when displaying static images. Many retailers and commerce downplay the dangers, but the phenomenon occurs with many different units. Do not leave the cable or Dss menu screen up for an hour or two. Be true when displaying Htpc or computer game video with static images.
o Many of them look in effect bad when displaying non Hd Tv. This question has lessened with improved internal video processing and scaling technology. Some plasmas in effect look pretty good with a better capability Dvd feed.
o Many plasmas suffer from rather severe image artifacts although this is also enhancing greatly due to the better internal processing.
o Some plasma displays have high power consumption. (Can be three times that of a accepted tube Tv)
Lcd flat panel:
Advantages
o They’re thin! Some are only three inches thick.
o They have no image burn problems like plasmas do.
o Good photo on most newer sets.
o Long life (50,000 – 60,000 hours)
o You can get a true, 1080P native resolution display.
Disadvantages
o Sizes over 30 inches are priced above equivalent sized plasma displays.
o The older units don’t have photo capability as good as plasma displays.
o Black and dark pregnancy is not as good as plasma yet.
Rear angle Tv can be whether digital or Crt based. The Crt units are going away fast as consumers move to thinner, lighter digital rear angle Tvs. At this point, the better Crt rear angle sets offer extraordinary doing for the money. You can get a 50+” Hdtv ready Crt set from good associates such as Panasonic and Sony for under ,500. These bargains will be gone soon as production of Crt rear angle sets stops. Panasonic has indicated the 2005 model year will be their last for Crt Rptvs.
The disadvantage to Crt rear angle Tvs is size and weight. They too will suffer image burn problems if left with a static image for too long. They need spoton convergence to look their best. Most newer units offer multi-point convergence adjustments to facilitate this.
There are some new types of flat panel displays that will be released for buyer use soon together with Organic Light Emitting Diode (Oled) and Sed. These promise even better image capability than whether Lcd or plasma when fully developed, in addition to lower cost, thinner profiles and much lower power consumption.
In a nutshell:
Front angle – Large image, can have spectacular photo capability even on a huge screen – More difficult to set up, need to place the projector in the town of the room somewhere, noisy(some), must use better capability sources to get the most benefit.
Plasma – cool factor, thin, look good for Hdtv – Image burn problems, can sometimes have a mediocre photo for all but Hdtv sources
Lcd – cool factor, thin, look good for Hdtv, no Image burn problems, – expensive for larger sizes, can sometimes have a mediocre photo for all but Hdtv sources.
There are many display technologies available today. No one display is best for all situations. take the one that best fits your take your exact requirements.
