Amazon.com Product Description

Toshiba takes digital light processing (DLP) technology into the future with its 46-inch TheaterWide 46HM84 HD-ready rear-projection TV. The 16:9 46HM84 uses a proprietary system called TALEN (Toshiba Advanced Light Engine); based on the Texas Instruments HD2+ DLP chip, it enhances brightness and contrast while keeping the 1,280 x 720 progressive resolution (720p). Toshiba's TheaterWide TVs challenge direct-view CRT models when it comes to reproducing deep blacks and details in dark or shadowy scenes.

What is DLP? DLP, or digital light processing, is a technology that bounces a colored light beam across an array of hundreds of thousands of hinge-mounted microscopic mirrors attached to a single chip, called a micromirror device (below, pictured with the head of a pin). Each of the mirrors can be pointed toward or away from the light source thousands of times per second, providing not only minute color detail, but also sharper resolution than even LCD displays.

This set is HDTV-ready (it needs an optional high-definition receiver to get HD signals), but can improve standard-definition video, thanks to Toshiba's multistep PixelPure video processing system, which optimizes the three main picture quality factors: resolution, contrast, and color. All incoming signals are converted by the built-in scaler to match the DLP chip's native 720p resolution.

PixelPure encompasses eight different processing circuits. Among its components are 6.2-million-pixel oversampling (for higher perceived resolution), real-speed progressive scanning (which uses additional sampling points to create smoother diagonal lines), a Magic Square algorithm (for smooth, natural color gradation), Dynamic Contrast Enhancer (for higher perceived contrast and increased color saturation), and Color Detail Enhancer (to maintain fine image detail in color-saturated areas).

DLP technology uses an optical semiconductor, known as the Digital Micromirror Device, or DMD chip, to digitally manipulate light. The chip contains a rectangular array of up to 1.3 million microscopic mirrors, each measuring less than one-fifth the width of a human hair. A DMD panel's micromirrors are mounted on tiny hinges that enable them to tilt either toward the light source (on) or away from it (off), creating a light or dark pixel on the projection surface. The bit-streamed image code entering the semiconductor directs each mirror to switch on and off up to several thousand times per second, enabling the mirrors to reflect pixels in up to 1,024 shades of gray.

The HD2+ DLP chip ensures an ultraclean image by filling in the dimples, or vias, in the mirrors to avoid stray light. It increases both brightness and contrast, resulting in an impressive color-corrected contrast ratio (2,200:1) at 1,100 ANSI lumens. The set's TheaterFine HD Super Fine Pitch screen reduces the physical space between the lines on the lenticular screen, resulting in a finer, sharper, more detailed picture.

Toshiba's DFine Hi-Speed VSM (velocity scan modulation) improves contrast and overall picture sharpness, while the CableClear DNR+ digital noise reduction optimizes poor NTSC signals from antenna or cable, further eliminating video noise ("snow") for a clean, crisp image. Cinema Mode circuitry (3:2 pulldown switch) identifies original film-based content from DVDs, then reassembles the frame sequence to more accurately reproduce the original 24-frame-per-second material.

A 3-D Y/C (4 MB, 10-bit) digital comb filter with Vertical Contour Correction helps eliminate dot crawl and color bleed and significantly reduces detail noise, seen as shimmering or flicker, in complex or intricately detailed scenes. Color temperature controls allow you to adjust white balance. The Warm setting reduces the color temperature to an NTSC standard 6,500 degrees Kelvin and delivers a redder image that is ideal for display in a dimly lit room. Medium and Cool provide a progressively bluer image for the best picture as room light levels are increased.

The 46HM84 has plenty of inputs for connecting all your audio and video components. In back you'll find two RF, two composite video, two S-video, and two HD ColorStream component video, as well as a High-Definition Multimedia Interface (HDMI) digital input. HDMI is an uncompressed, all-digital audio-video interface that supports standard, enhanced, or high-definition video, plus eight-channel digital audio--all on a single cable. A set of front composite and S-video inputs make hooking up a game console or camcorder a snap.

Other features include HD Window dual-tuner POP (picture-on-picture) with PIP sound for listening to two programs simultaneously, the new Radiance DC lamp with high brightness and lower power modes for extended life, individual audio-video settings by input type, sleep and wake timers, Real Speed progressive scanning to create smoother diagonal lines, the Color Transient Improver for sharp transitions on color changes without bleeding, and the Color Detail Enhancer to maintain fine image detail in color-saturated areas.

Aside from the 20-watts-per-channel stereo speaker system, the 46HM84 uses MTS for programming with stereo sound, and SAP for receiving a second audio track in another language. Meanwhile, SRS WOW combines 3-D Sound (simulated surround sound from any stereo audio) with TruBass (yet another low-frequency enhancement) and Focus (which clarifies voices). The StableSound volume leveler eliminates drastic volume spikes while changing channels or during commercial breaks.

5.0 out of 5 stars OUTSTANDING PICTURE & QUALITY, August 25, 2004

By	H. Brake "hbrake2" (Jonesboro, AR United States) - See all my reviews (REAL NAME)

This review is from: Toshiba 52HM84 52-Inch HDTV-Ready Projection DLP TV (Electronics)

I researched televisions before buying the 52HM84. I compared DLP, LCD and Plasma. I decided on the DLP due to its size and picture quality. I had narrowed my research down to the Mitsubishi and the Toshiba - since these both us the HD2+ DLP chip. The Mitsubishi had a glare on the screen and the Toshiba didn't. The quality of the picture is outstanding. The technology to clean up messy analog signals is outstanding. I could not be happier with this purchase. I highly recommend a buyer to purchase the matching Toshiba ST5284 stand for the set. Together - the set is perfect! GOOD WORK TOSHIBA!

5.0 out of 5 stars Excellent set for a very reasonable price, January 4, 2005

By	OC Resident (Huntington Beach, CA United States) - See all my reviews

This review is from: Toshiba 52HM84 52-Inch HDTV-Ready Projection DLP TV (Electronics)

I spent over two years looking at high definition televisions before settling on the Toshiba. The features that sold me were the outstanding picture quality, both brightness and clarity, as well as the very reasonable price for the size and features of the set. I spent several months watching the prices in the retail stores, but never found the price dipping much below the $3000 that every retail store seems to want to sell it for.

I have never purchased an item as large as this from Amazon, and I was a bit reluctant to do so. Given the reviews to date and comments regarding reliability, I was concerned about buying from a company that did not have a good extended warranty option available. While Amazon does sell third party contracts, I did not find them to be particularly well known. I was leaning toward buying the unit from Sears, where the extended warranty is supported by a very large service organization, and the organization is staffed by full time Sears employees who have always been very professional with other items I have needed service on. The down side was a $700 difference in price between Sears and Amazon.

What finally convinced me to choose Amazon over the local retailers was that I was able to double the warranty by charging it on my American Express card. My only other hesitation was that I needed the unit carried up a flight of stairs, and while I knew that the local Sears delivery person would carry it up, I was not sure what to expect from a trucking company contracted by Amazon.

My set was delivered yesterday by Eagle Freight. They scheduled my delivery between noon and 5:00 pm, and they showed up at 4:00 pm, after first calling to let me know they were on their way. The drivers were very friendly and professional, and they gladly carried the set up to the second floor and waited while I confirmed it was working properly. They even took away the empty packaging. Since I am familiar with electronics equipment, I knew how to quickly set it up without their help. I'm not sure they would have known how to set up an HDTV had I needed assistance, but fortunately this was not an issue for me.

The TV was up and running within 3 minutes, and the quality is absolutely breathtaking. After much trepidation about purchasing such a large item over the internet, I am quite pleased that I chose to do so. I'm still debating whether to add an extended warranty or just take a chance on it with the American Express warranty doubler as a backup. The extended warranties do not generally cover the replacement bulb, which cost approximately $300. Since this is the most likely part to fail, I suspect that I would be better off taking my chances and skipping the extended warranty option. However, it's nice to know this option exists if I need it.

For those of you thinking about purchasing this item from Amazon, I would recommend you give it a try, as long as your credit card will double the warranty, and you do not need much help in hooking up the set. I will update this review after having a few weeks to get more familiar with the TV.

3/5/2005

After having this set for a few months, I am still thoroughly impressed with it. The quality is outstanding, and I have had no issues to date with reliability. I did purchase a 4 year Warrantech warranty for around $200. This extends the warranty beyond the one year Toshiba warranty for a total of 5 years of coverage. Hopefully I will never need it, but for $200 it seemed well worth the price.

1.0 out of 5 stars Inspect screen carefully before accepting delivery., October 3, 2005

By	Y2KPony "Leif" (CA, USA) - See all my reviews

This review is from: Toshiba 52HM84 52-Inch HDTV-Ready Projection DLP TV (Electronics)

Before signing and accepting delivery of any Toshiba DLP, be sure to check the screen to make sure that the coating on the inside of the screen is uniform. On mine, there was a circle about 10" in diameter that you can see in certain lighting and even when the TV is off! It will appear lighter than the surrounding areas at times and can be annoying. I called Toshiba and had a service man come out and even though he acknowledged that this is common, Toshiba will not replace the screen. I would have given them a negative 10 if it were possible just because of their attitude. So, look at the screen VERY carefully before accepting or purchasing. If you see this problem, refuse to accept it. Or else just buy a Samsung or Mitsubishi DLP to avoid the problem I have.
