Editor's HDTV Pick

HP 47 inch MediaSmart 1080p LCD HDTV "Out of the box" digital media platform. Enjoy videos, pictures and music from home network + digital media delivered over your broadband Internet connection + 3 x HDMI

The Sharp AQUOS 32 inch GP3U models are Sharp’s second generation of 1080p, Full HD, LCD HDTVs designed specifically for gaming. The outstanding feature of these AQUOS models is the Vyper Drive game mode for eliminating game lag. Lag (high latency) can be a cause of frustration for gamers reducing or eliminating their reaction time window.

The GP3U comes in three colors; black, red and white and all have plenty of connection options, an easy access side-mounted terminal panel and bottom mounted speaker for minimum width. For viewing flexibility, the LCD HDTVs sit on a swivel pedestal and have a wide viewing angle (176 degrees) in both the horizontal and vertical planes.

While most HDTVs are purchased for watching HD video a significant percentage are making their purchase for gaming console use as evidenced by a study by Frank N. Magid Associates. It indicated that for nearly a third of those in the 21 to 34 years old range their HDTV purchase was driven by the desire to connect it to a gaming console such as an Xbox 360 or PS3. Manufacturers of flat panel displays are responding to this consumer trend with their product design with response time improvements and the inclusion of game modes.

Characteristics of Video Games

Video games look better if the display has a high brightness capability and colors are well saturated. Games often contain text to read, menus to scroll and complicated control console details to discern so image sharpness is important. Dark scenes are prevalent in games requiring high contrast for accurate display of shadow detail. While 480p and 480i were common output resolutions, game consoles now have right up to 1080p (Full HD) video output. At the moment, probably the greatest test of HDTVs for gaming is achieving a quick enough response time to match the speed of gameplay.

Sharp added the 37 inch LC-37D64U and 32 LC-37D64U after the launch of its first four D64U sizes from 42 to 65 inches. Full details of the specification for these 1080p LCD HDTVs are covered in our review of the four larger models. However, feature highlights are as detailed below.

• Dynamic contrast ratio 10,000:1 for deep blacks and more detail in darker scenes
• Very fast 6ms pixel response time (4ms on larger D64U models)
• Extended color gamut from Four Wavelength Backlight System
• Very wide viewing angles – 176 degrees
• Sharps Advanced Super View (ASV) / Black TFT panel Advanced Super View (ASV) LCD 10-Bit Panel
• OPC function (automatic brightness adjustment to changing ambient light)
• Slimmer depth (25 percent over previous models)
• Energy Star-compliant for much lower power consumption.
• 3 HDMI ports + PC input

Sharp’s Special Edition Full HD 1080p (1920 x 1080 pixels) resolution LCD AQUOS models have a premium performance specification and an attractive new Cornerstone design. Prominent features are;

• the new Advanced Super View (ASV) Panel technology,
• AQUOS Net capability for accessing customized Web-based content and real-time customer support,
• 120Hz Fine Motion Advanced Frame Rate Conversion for improved picture quality and
• the Five-Wavelength Backlight System for better natural color reproduction through a widened color gamut able to display very deep greens and crimson reds.

The Cornerstone design is a combination of a new textured finish to the black cabinet and corner accents to the bezel surrounding the screen. As always, technology shrinks with age and Sharp have been able to cut the depth by almost a third (28 percent to be exact) from the previous generation. If you’re planning on wall mounting the news that the weight has also dropped by 9 percent will be appreciated. Twin speakers (15W) are bottom mounted and detachable.

The Optoma TX7155 has a thoroughbred specification which when combined with its reasonable pricing is the value for money formula that marks a best selling product. The TX7155 DLP projector sits in Optoma’s business projector line but, it has also proved popular with gamers.

Placing it in the category of a portable projector are its small form factor and light weight at 3.2 lbs (1.45 kg).

For the business traveller who may have to make a presentation in less than optimum environments with high ambient light levels, the Optoma TX7155 can pump out up to 2500 ANSI lumens. It should handle most typical business application. Contrast ratio is good at 2500:1 however it is a Full On/Full Off figure which will be much higher than what the static contrast ratio would be but, it does give a basis for comparison.

Do I Need to Calibrate my HDTV?

Few consumers have a real need for a professional display calibration. What may lead many to believe they do are the default picture settings HDTVs are shipped from the factory with. Default factory setting are generally formulated for maximum impact on display at a consumer electronics store. Factory settings are commonly formulated for maximum brightness and contrast for the bright ambient light conditions in a store. Additionally color saturation may be boosted and sharpness adjustments tweaked upwards. When home in the living or entertainment room with a different viewing environment the default settings can look overdone.

Fortunately, the majority of HDTVs come with a number of quick select display modes that have been professionally calibrated for various video sources and viewing situations. Getting a good picture is simply a matter of selecting the appropriate setting for your viewing situation and video source.
Professional display calibrations are something to think about for high-end, expensive equipment. An expensive home theater installation is a logical candidate for professional calibration. If your viewing situation is not optimal then calibration is a waste of money.

Epson’s PowerLite 1705c projector is based on 3LCD technology and has the color accuracy, excellent color saturation and image quality that comes with it. Importantly, rated at 2,200 ANSI lumens it has the brightness to cope with higher ambient light situations, such as a well lit meeting room, in which one may be required to make a business presentation. The contrast ratio of 400:1 is not impressively high but, more than adequate given the intended use.

The Epson PowerLite 1705c is compatible with an XGA (1024 x 768, aspect ratio: 4:3) computer monitor resolution as would be expected of a business projector but, will also handle 720p and 1080i. At only 3.7 lb the 1705c is a very portable solution. You don’t have to connect a PC to make a presentation as there is a USB 2.0 port for loading your PowerPoint or video presentation. You can however, connect up to two PCs if you need to.

A bonus feature with the 1705c is 802.11 a/b/g wireless capable (up to 54 Mps) making it possible to stream content to the projector over a wireless network connection. A wireless connection is also convenient for monitoring and control. In fact, the 1705c will send maintenance and diagnostic reports automatically over a wireless network.

Set-up flexibility is always a desirable trait in a business projector. The PowerLite 1705c has automatic digital keystone correction which will handle an offset angle in the vertical plane between +/- 40 degrees. There is no horizontal correction available so the projector must be able to be positioned directly in front of the projection screen. However, there is some adjustment flexibility with regard to distance from the projection screen with a zoom ratio of 1:1.2. Unfortunately, the projectors noise level at full brightness is reasonably high at 40dB, particularly for an LCD projector. At a lower brightness, economy setting (1700 lumens) the 35dB rating is more acceptable

For the convenience of the presenter, a source search function automatically displays connected input source(s). The PowerLite 1705c comes with a well equipped remote control with mouse emulation functions and an electronic pointer. For security there is Kensington style lock provision and password protection. There is also a small 1W onboard speaker.

It’s always good to have a business projector which will start quickly (5 seconds for the 1705c) and shut down without an extended cool down time being required. The Epson PowerLite 1705c has an Instant Off feature for fast shut down.

Epson have a longer than usual two year limited warranty. The lamp warranty is however, fairly standard at 90 days. Epson’s Road Service program will provide a replacement projector typically within 1 business day.

The HD71 and HD65 share the same DLP projection microdisplay and most features. The HD65 has 1600 ANSI lumens brightness which is at the top of the range of what would be expected for a home theater projector while the HD71 has a lamp which produces 2400 lumens in line with Optoma’s promotion of the projector as a crossover between a home theater and business projector.

Both projectors have a single 0.62 inch DarkChip2 DLP chipset and associated color processing technologies from Texas Instruments including BrilliantColor. The color wheel is 6x speed which is faster than usual and should provide even further protection from rainbow effects which DLP projectors can be prone to. The native high definition resolution is 720p (1280×720). The Full On/Full Off contrast ratio
