What You Need To Know About Picture Quality

Tuesday, January 19th, 2010

The difference between good and poor picture quality can be seen by anybody. However, it is not very easy to understand the technical issues that make a picture look good. One very important element of picture quality is contrast ratio. Other aspects are the color saturation and color accuracy, and resolution is also very important.

The ratio between the darkest and brightest color your HDTV can produce is called contrast ratio. Your HDTV has high performance if the contrast ratio is high. Low color ratio means a dull experience: pictures will be washed out and details can be lost. However, it is unlikely you will buy an HDTV with poor contrast ratio. In recent years technology has improved greatly, which means even cheaper systems have fairly decent contrast ratios. Obviously best contrast ratios are expensive, but this is also getting cheaper.

Another important aspect of image quality are the black levels. Systems with poor black levels will have grayish blacks when absolute black is expected. Poor black levels can be especially annoying in dim light conditions, because in this type of light the human eye is very sensitive to dark images. Lot of users set black levels very low, to achieve absolute black. This is a mistake: by doing this, black shadow details can be lost.

High white levels make the images on the screen appear vivid and lively. This makes the viewing more pleasant. Again, lot of people make a mistake by setting the white levels too high: this way certain details and bright highlights can be lost.

Important characteristics of the images on your display are color temperature, saturation and accuracy. 6500K, corresponding to daytime illumination, is the standard for color temperature. This is the natural light temperature. Everything above this is bluish, and everything below is yellow or reddish. If the color temperature is not set properly, every color will be bluish or reddish.

Color saturation can be relatively easily adjusted by using the color patterns that come with calibrations discs or TV channels. Color accuracy depends on how your HDTV decodes the image data. These are pretty complicated issues. You may want to read more about this elsewhere, but if you only want to stay at beginner-level, it is enough for you to know that the decoders of your system should match the color encoding used in film production.

Color reproduction is also affected by factors like greyscale and the display characteristic (gamma) of your TV. But this is beyond the beginner-level image calibration. If you find this is an important issue, you will have learn about image calibration, or you will have to pay a specialist to do this.

The latest HD resolutions provide 5 times more pixel amount compared to Standard Definition. As a result, image is not simply clearer, but there is night and day difference: the smallest detail can be noticed on the image. If you want to have the best, go for 1080 capable HDTVs.

Another notion related to resolution is percieved sharpness. This is very similar to the concept of edge contrast used in photography, and it basically means that users have the choice to make the image borders crispier. This gives the sensation of better image quality with the same resolution.

Building a Great Home Theater

Tuesday, December 8th, 2009

It could be very easy to spend tens of thousands of dollars building the ultimate home theater experience for you and your family and if you use your home theater on a regular basis and have the money to spare you might find well worth the investment. However, you can also build a fantastic home theater for significantly less money if you are willing to put a great deal of effort into finding the right parts for the right price for your system. Everything comes down to matters of preference and available funds when building any sort of home theater.

The truth of the matter is that most of us cannot afford to spend more than ten thousand dollars creating the home theater of our dreams. Many of us must seriously budget well in order to spend a couple thousand dollars on our home theaters. The good news is that for a few thousand dollars you can create a truly phenomenal home theater if you do your homework and invest your money wisely in components for your home theater system.

My first recommendation when building a good quality home theater is to buy one piece at a time rather than building it all at once. This allows you to constantly upgrade your system without breaking the budget all at once. It also allows you the time to save up for better quality pieces within your system rather than attempting to make an all or nothing purchase. One thing to remember when purchasing pieces individually is to make sure that they are all compatible (this is especially important with speakers, which I recommend purchasing together as a set whenever possible).

The television is the first thing you should purchase when building your home theater as almost everything in your home theater will center around your television. High definition televisions are becoming more and more common and provide superior quality to many other televisions you will find on the market. If you have the means with which to purchase this sort of television I highly recommend that you do so. Once you have your television you can begin purchasing other components in order to complete your system.

The next component I recommend is a receiver or amplifier. This is the piece that brings all other components together. Without a decent receiver it is virtually impossible to have a decent home theater. The receiver acts as a sort of conductor for the sound and picture of your home theater. This is a piece of equipment that should not be skimped on when it comes to quality, as you will completely miss an important part of the ‘theater’ experience without it.

Next are the speakers. Speakers are also very important to the ‘theater’ experience of your home theater. The speakers are what provide that ‘movie quality’ sound that is so important to most enthusiasts and what will make your system the envy of the neighborhood. I highly recommend purchasing speakers as a set in order to insure compatibility.

Finally, the DVD player or recorder rounds out the system. It is up to you and your preferences whether or not you wish to invest in a high dollar (at the moment) high definition DVD player. If you have HD television and plan to purchase HD disks for your movies then this is the way to go. Otherwise it is a complete waste of money in my opinion until the rest of your system rises to meet the technology. The good thing about purchasing one component at a time is that you can constantly work towards upgrading your system to meet rising technology.

Hdmi Auto

Hdmi Auto
Why am I not getting 5.1 surround sound from the HDMI player to use a coaxial digital surround system?

My System Surround (Philips MX5700D) do not have HDMI out. But it provides an excellent surround sound with DVD. Then I bought a DVD player with HDMI (Pioneer DV490V-s). I tried my best to get the surround sound, but still struggling. Player HDMI has been connected to the HDMI port on the TV. Television has an optical output, but my surround system has a coaxial digital therefore unable to hook up directly to a TV system surround. I hooked the HDMI player I am not sure my 5.1 surround system if it decodes an external signal is used via coaxial digital. I do not want surround sound without HDMI. So please someone tell me how I can resolve this problem.
