Toshiba REGZA 26HL67, 32HL67, 37HL67 and 42HL67 720p HD LCD TVs ReviewToshiba’s HL REGZA models are 720p High Definition LCD Televisions and although sharing a majority of features with other models, are the entry level models of the REGZA series. The Full HD, 1080p models also have ColorBurst for a wider color gamut and CE-Link enabled HDMI for CEC control of other devices through a HDMI cable. The premium REGZA models are the Cinema Series Models which include 120Hz refresh rate ClearFrame technology for motion blur reduction and Deep Color.
The Toshiba HL REGZA models have a gloss black cabinet with dimensions made smaller by the compact size of the twin 20W bottom mounted speakers. Toshiba’s new “Soundstrip” speaker technology allows for a thin speaker design with enhanced dynamic range without losing any home theater sound quality. The RF REGZA models have even smaller dimensions with an impressively narrow surrounding bezel of less than 1 inch. The RF models are worth considering if your new television needs to fit into a tight space or you wish to maximize your viewing area for the space available. A couple of handy across-the-range features for the Toshiba REGZA are:
Native ModeA nice bonus feature of for the REGZA televisions is Toshiba’s Native Mode which restores the size of the picture by the 3-5% that is generally lost during the normal over-scanning that occurs on traditional sets. The loss occurring in traditional sets is due to a process called blooming where the image size increased slightly when a brighter overall picture is displayed. There is probably not a lot to see in the extra picture though as directors make sure that no important action takes place in this additional picture area not all viewers may seeing. Toshiba REGZA Digital Video ProcessingHigh Definition television video processor performance significantly influences picture quality. This is due to high definition displays magnifying any image defects including noise and image artifacts caused by poor video processing. Lower resolution displays lack of detail tends to mask defects. Image noise and artifacts can be introduced through the compression required to pack hundreds of channels within limited transmission bandwidth or during deinterlacing which is required to convert NTSC or PAL interlaced signals to progressive-scan for digital display. As well as deinterlacing and scaling video signals to fit native resolution, video processors are required to improve image quality and remove any noise or artifacts. Toshiba’s PIXELPURE 3G 14-Bit Internal Digital Video Processing is performed by a 3rd Generation Toshiba 14 bit digital video processor running at 333MHz. The incoming video signal is continuously monitored for adjustment of multiple picture quality parameters including progressive scanning, dynamic gamma, dynamic back light control (for contrast) and improved noise reduction. To put the 14 bit processing capability into perspective, it should be noted that all video sources are 8-bit per pixel. Extra bit capacity helps improve the precision of video processing. However, higher bit rates do not equate directly to improved video processing performance. So the best way to determine your personal level of satisfaction with the picture quality of a TV is to view it in different ambient light conditions while displaying a variety of light and dark video sources of varying resolutions. DynaLight Backlight Control for Dynamic Contrast Control and Deeper Black LevelsDynamic Contrast Control is utilized by LCD television manufacturers to improve contrast ratios. In Toshiba’s case, their DynaLight Backlight Control monitors each video frame adjusting backlight intensity to the optimum value for each image. Using DynaLight Toshiba achieve a dynamic contrast ratio 5 times the original panel contrast. DynaLight also improves the black level which is one of the advantages plasmas have traditionally held over LCD displays. Color Temperature ControlToshiba’s REGZA LCD TVs provide a three setting color temperature control for adjustment to personal tastes. The “warm” setting produces a redder image to the NTSC standard 6500 Kelvin which is suited to lower ambient light situations. The association of degrees Kelvin to color is counter to the usual association with blue being the hotter color and red the cooler. It comes from the colors being related to the standard based on the heating of an ideal black body radiator - when heated it first becomes red then yellow then “white hot” and so on. The “Medium” and “Cool” settings provide a progressively bluer image for the best picture in higher ambient light conditions. REGZA Sound SystemSRS WOW (including 3D, TRU-BASS and FOCUS)REGZA LCDs have WOW patented sound technology by SRS Labs. WOW improves the dynamic audio performance of twin speakers by expanding the size of the audio image and improving the perception of low frequency sound (more deep rumbles for action flicks). 3D WOW provides a panoramic three-dimensional audio image that extends the sound field in both the horizontal and vertical planes. TruBass TruBass enhances bass performance, restoring the perception of low frequency tomes by using the harmonics present in the original audio source to recreate the low bass frequency information. It delivers the perception of deep, rich bass up to an octave lower thn the physical low frequency limitations of small, medium or large speakers and headphones. FOCUS FOCUS lifts the dialog out of the sound mix and elevates the sound image, creating the perception of image height. Where speakers are located below the height at which viewers will be listening (such as with the REGZAs bottom mounted speakers) the sound field produced can be raised electronically. MTS Stereo/SAP with dbxAn MTS (Multi-channel Television Sound - sometimes called BTSC) decoder enables the television to accept and decode a broadcast stereo signal. Dbx is a suite of noise reduction systems by a company of the same name. The REGZA MTS, unlike some systems doesn’t delete the dbx encoded stereo information which is used to increase the signal-to-noise ratio to assist in noise reduction. Dolby Digital Dynamic Range ControlThe Toshiba REGZA LCD comes with Dolby Digital Dynamic Range Control which allows one to limit the dynamic audio range compared to that originally recorded. It very usefully cuts out the peak volume that comes with special effects or heavy action sequences while still enabling one to hear the dialogue ie. it brings the loudest and softest sounds closer together. It’s an excellent solution for keeping children asleep and the neighbors friendly while still enjoying your viewing. User Reviews and Price Comparisons
