When thinking about how to evaluate Toshiba’s latest flagship SV650, it is obviously not appropriate to focus on any one single technology, because the technology applied on the SV650 has been in touch with us before, such as dynamic partition control of LED backlighting, frequency multiplication and black insertion. Dynamic optimization techniques, etc., but these top-level technologies have achieved better results than ever before on the SV650. Whether it is test scores or subjective feelings, it is equally surprising that Toshiba’s unprecedented ability to fine-tune every professional function The options, so spend a lot of ink on these features, will let readers understand the potential of a powerful LCD TV.
This test is 46-inch 46SV650, as Toshiba's flagship model, first of all, LED backlight and digital one receive function is essential, the image engine is Meta Brain Premium, behind the Premium is not added, "AutoView", " "ClearScan 200Hz", "LED Local Dimming", is based on it to achieve, of course, its inherent strength but also to be slowly analyzed, from the configuration, SV650 has a new design, 4 sets of HDMI input, SD and USB slot, Ethernet port can achieve DLNA, although most of the top models are configured, but the details of support can only be evaluated in terms of strength, you can first look at the summary, and then carefully look at the later decomposition.
Test summary or reasons for the best of the year:
1 The high contrast brings pure black, and the purely numerical value does not seem to fully explain the problem
2 wide color gamut and partition LED backlight control (LED Local Dimming), this is the most essential configuration this year
3 ClearScan 200Hz brings dramatic improvements in dynamic resolution. The 900 line is the best LCD of the year and the hardest to improve.
4 Intuitive + professional image adjustment capabilities, you seem to be able to complete the design of a TV image style yourself, and these are the secrets of Japanese television stronger than other manufacturers' products, not only need technology and knowledge but also need to appreciate .
5 HDMI INSTAPORT reduces the switching time between the two HDMI interfaces to 1.8 seconds. Users with a large number of peripheral devices will know how important these advances are.
Disadvantages: not enough light, sound effect is not shocking, easy to vacuum the shell, the use of multi-media play is virtually empty, but these will not affect the evaluation of the strongest models of the year.
The appearance of the SV650 is applied to Toshiba's innovative design: “Haiyun borderâ€, which is called “deep space suspended under the sea, and the colorful and fascinating corals gradually disappear in the crystal clear waterâ€, and the border surface material. It is transparent, from the dense to the sparse dots, it makes the whole frame look three-dimensional. I think this is the crowning touch of the new design. However, even though this smooth surface meets the market trend, the characteristics of vacuum cleaners have to be considered. , especially in a city like Beijing.
The overall sense of the panel is very strong, in addition to the brand logo in the center, only the bottom right corner base two pointed, like a football, the surface is still using a smooth material, and the body to reflect each other. As with previous Toshiba bases, all have a fixed cable design, and a device with multiple strapping cables on the back can solve the problem for users with many devices.
The body thickness of the SV650 is not thin, and even thicker than the previous CCFL models, but the shrinking back edge design reduces this visual experience. In fact, individuals have always believed that for the LCD TV, thickness and picture quality. It is often proportional to.
The main audio and video interface, side input and body control buttons are all designed on the right side of the fuselage, giving the operator the greatest convenience, the interface types are complete, the number is sufficient, and the headphone, Ethernet, USB, and SD card slots are also greatly expanded. SV650 use space. The random remote control is still the model adopted by Toshiba's high-end series, and the matte feel has always been favored by the author.
The beginning said that SV650's powerful system optimization capabilities, then we decompose and describe each function one by one, first look at the picture quality part of the menu, basic options needless to say, SV650 comes with a variety of preset modes, including dynamic, video and shadow drama If you do not want to adjust, you can choose the right preset mode directly.
Advanced image settings are rich in content, and the control view is the most intuitive performance of image processing optimization, that is, the relationship between the gray level of the input signal and the output brightness. With its help, you can also become a master.
Advanced image settings, some of us are more familiar with, such as color temperature control options 6 color adjustment, but in the color temperature control which has 10 files adjustment, I carefully tested the color temperature value of each file, from 5700K to 10500K every 500K color temperature File adjustment, no matter if you are pursuing the exact restoration of D65, or the bright sense of high color temperature, you can find your favorite color temperature inside.
Automatic brightness sensing is Autoview, which controls the brightness of the backlight according to the ambient brightness to protect the eyes and ensure the best picture quality. Everybody is not unfamiliar with this, but the power of the SV650 is that you can manually set the range of backlight changes. The non-linear relationship between the ambient brightness and the actual brightness, according to personal preferences, in the day and night to get the desired brightness.
The black and white levels in the advanced image settings specifically control the output of near-to-white and near-black image reviews, which enhances the contrast of the image. Blacks are darker and whites are brighter. Of course, the details become slightly indistinct and static. Gamma is similar to Photoshop and other tools to modify the brightness curve of the image to control the brightness of the screen, and these changes are to see the change of the theoretical curve through the control view, intuitive meaning is here.
The super-resolution function is a standard-definition up-converting technology independently developed by Toshiba. The common up-conversion technique is simply interpolation, and it is prone to deterioration such as saw-tooth. The super-resolution is as good as possible with powerful computing power and advanced optimization algorithms. The image performance is like the TMT Blu-ray player on the PC can enhance the DVD quality through the simHD plug-in, but it requires CUDA hardware acceleration, visible Toshiba's super resolution for the TV, computing power has been a very high level For the effect of super-resolution, the previous test article has been compared, it can not turn SD into HD, but for the SD video source that is still in existence today, it can be comparable to Sony's DRC. Expert mode is not previously encountered, it seems to be through the closure of some of the three primary colors, to reflect the role played by color saturation and tone adjustment.
Then let's talk about image stabilization and ClearScan200. The former is what we often call the 100/120Hz frequency multiplier. Its effect and role is that the operation generates a new frame of image and clips it in the original image, making the human eye see more coherent and smoother dynamics. The image, the disadvantages of the author also specifically mentioned in the article, that is, fast-motion and image damage, Toshiba did not radically to 4 times the frequency, but also because of this, but added another dynamic enhancement mode, insert the black scan, this A technology was used as early as the CCFL lighting period, but due to the lamp switch speed is too slow, resulting in flicker and brightness decreased, the effect is not obvious. The high-speed switching effect of LED makes this technology rejuvenate. We can see this kind of black stripe falling from the top of high-speed photography (1/800 second shutter). effect.
These two technologies are not new, but after the SV650 is turned on, the 6.5ppf dynamic resolution test chart is actually measured, and the reading can reach 900-950 lines. This is really an amazing result. In the past, LCD dynamic optimization technology could reach at most. Visual readings around 750 lines.
Photos can not reflect the feelings of the eyes, for reference only
LED partition control is to extend the dynamic backlight control to the block, the same screen image is clear and dark, the traditional changes in the backlight can not be on the same screen brightness and light to enhance, and partition LED backlight control can do it, completely improve the contrast of the LCD , Just open the LED brightness control, the system will automatically control the brightness distribution according to the image, we use the old method - the mouse seduce independent backlight brightens, the other part is darkened, plus long exposure, take a picture of the effect.
The sound quality is not the strength of Toshiba LCD TVs. The thicker SV650 brings some space to the subwoofer. The low-frequency feel is improved compared to the past. The sound adjustment menu is equipped with Dolby Smart Volume to avoid TV program sounds. Difficulties caused by the inconsistency of size, sound enhancement is also more abundant.
The setup menu contains AV connection settings and channel management options for digital TV and analog TV. The AV connection section allows the user to manually modify the HDMI audio input mode. The connection PC can also use analog input. The optical output can be PCM or source code. Access home theater system. The HDMI input on the SV650 has an HDMI INSTAPORT design, which allows the TV to switch between different HDMI inputs in 1.8 seconds, compared to 5-6 seconds for typical models. The black screen is greatly reduced.
The media player is a system menu, which can play SD and USB interface memory, but the seemingly supported file format is not very rich, this is a common problem of foreign brands, not much to introduce. Some other convenient functions also fully embody the humanization advocated by Toshiba. Making good use of it can greatly increase the efficiency of television use.
With super resolution and excellent noise reduction circuits and interlaced signal optimization capabilities, the SV650 shows a clear and natural picture in watching TV programs, with no jagged and digital noise. This was in the evaluation of Toshiba's series of high-end TVs. Has been embodied, a wealth of proportional adjustment mode allows users to fully adjust the screen utilization, digital television reception we are already familiar with, nor too much introduction.
The performance of each item in this test score table is very good. The 46SV650 should adopt the SPVA panel. The ANSI contrast test score less applied on the TV also reaches 1250:1. The static contrast ratio near 4000:1 is astonishingly high. With the help of LED backlighting, tens of thousands of dynamic contrast ratios are also more convincing. Obviously, the inherent difference between liquid crystal and plasma in contrast is being weakened by SV650, and the same plasma has a major advantage over liquid crystals is dynamic. Sharpness, the previously analyzed double dynamic optimization technology, has allowed the SV650 to achieve an unprecedented performance of LCD TVs. The same LED used in the SV650 may be a three-primary-color RGB LED because the color gamut results reach 87% (NTSC). This has reached the scope of the wide color gamut, but compared with those models claiming to use three-color LED backlights, this result is not very high, so the author only used one possibility, if it is a white LED, that is also commendable, currently The source of the program may be uncomfortable with display devices that are too wide in color gamut.
Under full black display, we can see that the panel has a slight corner light leakage, which seems to be a feature of the SPVA panel, but because the value is very low, if it is not a long exposure, it is difficult to be aware of, especially in the open LED backlight control after that. The restore of the color gradation is good, and the gray scale of the dark part can be completely restored. The test of the GT racing car on the gray scale has passed smoothly and there is no stratification. Toshiba's high-end LCD TVs are highly adaptable to connecting to computers. There are also special proportioning modes under VGA connection. Even if your laptop can't output 16:9 video, you can stretch it to full screen. Even less is point-to-point. Words.
The following is the actual screen for playing Blu-ray movies and digital photos. After the previous introduction to the image processing capabilities, it is safe to say that the SV650 can give you either the standard, or bright, or soft and any style you want, so the following In the standard mode of the image screen, only a slight reaction to the side of the SV650, for reference only:
