TV allows you to control stored on the computer photos, videos and music files.
This Toshiba 42SL833 at an affordable cost and features a variety of proprietary systems and video processing settings color accuracy. System for processing Active Vision 100Hz refresh rate increases of up to 100 frames per second, thereby increasing the accuracy in dynamic plot. An integrated system of Dolby Volume eliminates annoying volume differences when changing channels or switching between devices so constantly maintaining optimum levels.Introduction The design of this TV
developed Dane Jacob Jensen, who for the last two years has partnered with Toshiba. Visually, this model is pretty good, although not as good as the more expensive models of the company. But HDTV Toshiba 42SL833 stands a very good build quality, and despite the elegant look, is quite heavy 19.6 kg.
Compact design TV features smooth straight lines and sharp angles of the frame around the screen. Triangular rotatable support connects the display with a flat tabletop stand. Structural stability is provided and four rubber pads on the underside of the stand.
Under the screen you can find the touch buttons to change channels, adjust the volume, access the menu, which, unfortunately, does not glow in the dark. We also noted a good enough anti-glare effect. In this regard, about the same as a TV Toshiba recently considered models Sony EX521 and EX720, but it loses a little in terms of optimizing contrast in brightly lit room. The disadvantage of reflection and giving black lacquer finish.
On the rear panel is a standard set of interfaces, where most of the connectors has a horizontal orientation. Back directed three inputs HDMI with Audio Return Channel ARC of the four antenna connector, Ethernet, optical port S/PDIF, YUV, RCA and SCART. On the sidebar, located only one input HDMI without support ARC, two ports USB one for multimedia, the other for the module Wi-Fi, Port CI +, 3,5 mm headphone jack and an RCA inputs for composite video and stereo .
beautifully designed, ergonomic and very nice to look at the remote control, unfortunately, has no backlight for the keys. Regza Link function works fine. The disadvantages include the fact that our Blu-ray player was not identified automatically with the remote control.
reception quality of TV channels
This TV is equipped with DVB-T tuner with automatic tuning and preset channels. You can change the order of channels to add them into the category chosen, manage subtitles, the choice of language in multilingual programs, etc.
Automatic setup is very fast, much faster than many other TVs, but it can be done manually. System navigatsiipo channels is great! The display a lot of information signal strength, clock, etc.. Decent picture quality at the same time.
very effective at great Blu-ray player deinterlacing system. There are only very minor irregularities. Image is too harsh and even reveals some minor compression artifacts footage. Nevertheless, SD scaling one of the best television channels, the picture clear and precise, without blurring.
Dynamic compensation Active Vision 100Hz not very noticeable increases in smooth-motion scenes, but does not create undue effect video film footage, works well with the personnel Kinoformat 3: 2 Pull Down but less effective in other versions. Another advantage Active Vision System 100 Hz is that it removes small noise. This TV does not support the video via USB, which is becoming more prevalent in today`s HDTV.
Works great system for automatic correction of sound -Dolby Volume. It smooths out volume differences in commercials and when switching video sources, aligns dynamic range with low sound. There are additional options for correcting the frequency range level. Sound quality, as well as any flat even the most upscale TV, not great, but acceptable. It may be adequate for watching TV, but not enough for a home theater. For high sound quality, you can use the digital HDMI interface with RCA or optical S/PDIF. Audio Return Channel function allows you to send audio from the TV back to the AV receiver via the same HDMI cable that was adopted by the input signal, and enjoy the sound format Dolby Digital Plus 5.1.
HD picture quality
HD picture quality is one of the most important components of the modern features HDTV, because televisions are often used in a home theater for watching high-quality movies with Blu-ray discs. To achieve the necessary level requirements often have to make adjustments videosproizvedeniya LCD panel, concern yourself with color, contrast, black levels and brightness. In this case, the calibration process was a difficult, but the results are there!With the factory settings
picture simply stunning! Excessive contrast, all video processing filters are activated, a bluish image, gamma perfect enough. Be a long and painstaking work to get it all correct. Name settings are completely different than the TV Samsung, Sony and LG. We switched to standard mode, to start from scratch.
the main menu shows the standard controls: the level of illumination, contrast, brightness, color, tint, sharpness, and there is a submenu "Advanced Settings" and "Settings expert mode". Control at minimum illumination led to the black level of 0.01 cd/m ². Of course, to maintain acceptable brightness and gamma, we did not drop to a minimum, and set the control to 50% without dinamicheskoypodsvetki, and 65% with dynamic lighting.
Available in the advanced setup menu function Color Master or color enhancement works, as well as on other TVs inefficient and so we unplugged it, manually adjusting the color temperature and the ambient light sensor to optimize the level of illumination and power consumption. And rigged Dimmer which can be disabled, the level of black/white and gamma settings quite different from those used by other manufacturers. Noise reduction has provisions auto or manual easy, medium, hard, processing Active Vision M100 standard/average/Off.In the settings
"Expert Mode" has many functions such as calibration patterns, filters to adjust the primary colors RGB red, green, blue. But most importantly, the "White Balance", which allows you to adjust the balance of the primary colors and strengthening RGB.
Calibration and Measurement
At default settings, the display emits a very powerful light output, not allowing to achieve a sufficiently deep black 0.09 level without dynamic lighting. To configure a range of shades of gray and we had to reduce the luminous flux of up to 110 cd/m. m to give a very low static contrast of 1170:1, the desired minimum below 2500:1.
Mid gamma curve close to the level of 2.3 which is very close to the reference 2.2, gray scale is very good, but not perfect, error rendering a mean of 2.4 very good, and a very nice color balance. Accurate color, but slightly oversaturated, especially red and green.measurements without dynamic lighting Color Temperature Color Balance RGB optimal level 100% Gamma gray dashed line -the ideal level/Blue -measured < img src="http://shsnls.com/foto/wp-content/uploads/posts/2011-11/thumbs/1322682784_ris14.jpg" alt = "LCD TV review toshiba 42sl833" title = "LCD TV review toshiba 42sl833" class = ""/> Color brightness reference curve -gray dashed line
Unlike Sony EX720, color brightness curve throughout is not accurate, including dynamic lighting, contrary to expectations, provides excellent results. In reality, the fact the backlight is not very visible on the screen, but it helps to achieve a deeper black color brightness balance curve and even gamma curve is lowered to 2.2 with an ideal color temperature of 6500 K. With dynamic backlight brightness of 122 cd/m ² with dynamic Contrast 50 753:1.measurements with dynamic lighting Color brightness Perfect Gamma Perfect
Calibration settings for a darkened room:
• Backlight: 50 65 with dynamic lighting
• Contrast: 98
• Brightness: 26
• Color: 48
• Tint: -1
• Master Colors: Off
• Temperature: 5
• Light Sensor: Off
• Backlight On or Off to taste
• Black/White: 0
• Static Gamma: -5
• Noise reduction: Off
• Resolution +: Off
• ActiveVision 100 Hz: Off
• R: 0
• G: -12
• B: -13
• R gain: -3
• G Gain: 1
• B gain: -1
filters for image
As usual, we did not use any filters. Noise reduction gives poor results, and Resolution + offers suits effect only on individual SD channels. Will not return to the quality of the system motion compensation Active Vision 100Hz, as mentioned in the previous chapter.
illumination of the screen can be seen periodically in LCD TVs with side illumination system, which is manifested in light "clouds" on a dark background, and less visible in bright areas depending on the LCD panel. This effect may vary from model to model, even in the same series.
tested model was not very susceptible to this drawback, but slight haze we still noted. Little noticeable they are only on a static image, but with enough ambient light disappear completely.

Toshiba 42SL833 has a very good build and nice design, but the connectors are uncomfortable, making it difficult to wall mount.
very good quality image has high contrast a bit lacking sharpness at the edges of the screen. Amazing color and fairly accurate maybe a little oversaturated in shades of red/green, almost perfect gamma, perfect gray scale, color temperature is ideal, but not enough deep black color for home theater recommended darkened room, the brightness decreases slightly after calibration, and viewing angles are not very wide.
Excellent dynamic backlight system works, but the film on the screen still lacks the depth of black. We also noted some shortcomings built-in speakers when playing dynamic music scenes.
HD picture quality is gorgeous, with a very good de-interlacing and scaling, higher than the average of all tested TVs.
the system interface presents a rich set of adjustment knobs, though calibration can be a bit daunting for beginners.
