Samsung LED ultra-thin LCD TV brings ultra-thin and amazing visual impact with its 2.99 cm body, but the high price will still make many pragmatic consumers flinch. Samsung B750 series is a mainstream model that combines its most advanced technology with high-quality CCFL backlit black crystal screen, high-quality black crystal LCD screen, 4 times dynamic image optimization technology and built-in high-definition digital wireless TV receiving function. As well as the colorful crystal design that attracts many women, it is enough to meet the needs of family members for a flat-panel TV. All users who have used the direct function of Internet @ TV network will have a new understanding of the role of TV. Today, we will take the mainstream size of the living room LA46B750U 1F as a representative to fully understand the strength of Samsung LCD TV.
Samsung LA46B750U 1F
The price of mainstream LCD TV is still not cheap, but it is a big deal. Women and men often have different views on family purchase. Men usually pay attention to performance and function, while women pay special attention to appearance. Samsung TV is full of Korean design style, which is extremely destructive to female users, and it is a headache for male users. Because they have little confidence in Samsung's performance in image quality, and because there are few opportunities to get Samsung's test products, before the test begins, the author was a little worried, but it turns out that these concerns are unnecessary. Let's first understand the detailed parameters of LA46B750U 1F:
Samsung not only made the panel crystal clear, but also fully demonstrated the crystal clear texture in the fuselage design. Coupled with the unique luster brought by the high-gloss mirror, the sense of fashion luxury has increased sharply. Although it is not as experienced as the red tone of Magic Crystal Rainbow II, the black tone of 750 is more likely to be favored by men. The sleek corner design of the back panel makes the not-slim fuselage shrink inward, and the edge of the transparent front panel is wrapped with a circle of black decorative lines, creating a visual lightness, and the back material also maintains the characteristics of specular highlights, thus maintaining the overall style.

The biggest highlight of the whole machine design is the transparent circular column, which promotes the crystal clear feeling to the extreme and makes the screen seem to be suspended in the air. The base can be detached from the column position, and there is a baffle in the attachment to seal the empty groove left after the base is detached, so as to maintain the overall beauty when hanging.
The buttons on the fuselage adopt touch design. Since it is rarely used, it can also be hidden in this way. Needless to say, visual beauty is also worth mentioning. At the same time, there is a faint light below the panel. It turned out that the semi-cylindrical lower frame created the spotlight effect. Samsung can be said to be playing lightly in design, and the effect is naturally difficult for counterfeiters to achieve.

Look at the back.
The remote control of Samsung TV is also unique. In addition to unconventional design, the curved handle at the back can also support the chubby back and put it on the table smoothly. The buttons are quite large in size and feel good, and there are few backlight designs with buttons.
Both the side input interface and the main interface area on the back are located on the right, so most people will be more comfortable to operate. The side interface is equipped with AV composite, one set of HDMI and two sets of USB interfaces, which are usually used, even if it is installed on the wall, it will not be embarrassing. A USB interface is labeled HDD, which means that it can provide a large power supply current, and using a mobile hard disk can save external power. Counting the side HDMI input, the 750 series * * * has four sets of HDMI inputs, so don't worry about too many devices. At the same time, the optical fiber output can be connected to the AV amplifier. For all-in-one digital TV, digital TV can receive 5. 1 AC3 audio, so this interface is very necessary. The two antenna interfaces include an ordinary analog cable TV interface and an interface connected to a DMB terrestrial digital TV receiving antenna. With the fishbone antenna, you can watch digital HDTV in the broadcasting city.

The richness of system functions often represents the strength of R&D manufacturers. International manufacturers usually constantly develop various new functions. For LCD TVs such as LA46B750 which support quadruple frequency, we need to see whether it has meticulous adjustment ability, because as far as display devices are concerned, the optimization function has side effects, and users can change the settings according to their own preferences and signal sources to obtain the best effect.
Samsung's system menu is designed to scroll by column and expand step by step, with many adjustable items and quick response. It comes with four image preset modes, all the normal adjustment items are available, and the tone adjustment is adjustable under HDMI. You know, many TVs have great restrictions on the adjustment of this project.
Advanced image settings
There are many professional setting options in advanced settings, including gamma adjustment, black, skin color enhancement and white balance adjustment. Users can find their favorite settings by carefully appreciating the differences, so I won't say much here.
200 Hz Quadruple Motion and Adjustment Options
At present, frequency doubling frame interpolation is the main technology of dynamic image optimization. Quadruple frequency can achieve smoother effect than double frequency, which is of great help to TV and games. However, a few days ago, we also analyzed the disadvantages brought by frequency doubling, especially the discomfort brought by watching movies. Samsung has done a lot of optional operations in this regard, and achieved different results by fine-tuning the preset algorithm. Users can also manually control the adjustment between effect and image damage to achieve the best adjustment for themselves and different program sources. The picture-in-picture function is naturally indispensable, and the careful adjustment of the position of the mother-child picture is more practical. Picture-in-picture with dual tuner is of little use, but the digital all-in-one can switch between digital and analog programs at the same time, and it is also of high use value.
Picture in picture setting
Audio-related settings include preset sound stage mode, equalizer and 3D sound effect switch. In addition, it also includes audio selection support for digital TV. The volume can be automatically controlled, and the speaker settings can be selected according to the cinema equipment. At the same time, the volume adjustment icon is eye-catching, and the circular design is very individual.
Television has more and more functions. Making full use of relevant settings will bring great convenience to the use process. There are many input interfaces, and the name editing function can be more clearly identified, eliminating the trouble of each test.
You can see many interesting settings in the system settings options. Samsung also added text notes under each option to facilitate readers to understand the meaning of the option. The explanation of each option is very clear and will not be explained here.
HDMI-CEC is the name of control signal in HDMI standard, but every household appliance manufacturer likes to give it a nice name. Samsung's name is Anynet+, which is a supplement to Anycall. Media can be played through USB and network interface, and mainstream HD videos such as ts format encoded by H264 can be supported. Fun Encyclopedia integrates children's education, cooking guides, games and other interesting content, as well as the strongest embedded function of TV surfing the Internet @TV. We will introduce these functions in detail later.
Most functions do not need to be adjusted frequently, and shortcut tools integrate common functions together, which is convenient for users to quickly open and adjust various parameters.
The built-in interesting encyclopedia of Samsung B750 is quite rich in content, including practical functions such as cooking recipes and children's audio books, as well as functions such as oil painting and leisure music to create a living atmosphere, as well as games to relieve boredom, which are suitable for all ages and easy to control.
At the same time, in order to facilitate users to understand the use of the machine and the connection of peripheral equipment, the built-in high-definition guide can realize illustrated teaching, which is far more friendly and easy to understand than the paper manual.
Although the concept of "3C convergence" or "smart home" was put forward a long time ago, and some manufacturers once implanted wince system into TV sets, it simply implanted PC functions into TV sets, without really considering what PC functions users need to realize synchronously when watching TV, and finally ended up with nothing. Samsung B750 also has the latest Internet @ TV function, which is more closely integrated with TV. Through the Ethernet interface of TV or wireless network card (to be purchased separately), Samsung LEDTV can receive and view news, weather and stock information in real time. This cooperation project with Sina has indeed made innovations in information resources and forms of expression. While watching TV programs, you can also learn the latest information in different forms.
As a digital all-in-one, Samsung LA46B750 can not only receive traditional analog TV, but also receive DMBDTH terrestrial wireless digital TV to realize high-definition channel viewing. On September 28th, more DMBDTH TV stations will start broadcasting, providing users with high-quality TV signals free of charge, and only need a fishbone antenna. Generally speaking, the sensitivity of Samsung's digital TV receiver is very high, and EPG electronic program list is very popular, so it is very convenient to immediately display the programs being broadcast on each channel in the channel list.

Although analog cable TV can't reflect the effect of large-screen LCD TV, and the number of digital TV set-top boxes is increasing gradually, Samsung LA46B750 also has a good performance in this respect, especially the customizable stepless adjustment ratio change, which is a new idea to make full use of the 4: 3 program display area on 16: 9 screen.

Next, we use BM-7 and power meter to measure the display performance and power consumption of Samsung LA46B750 in darkroom. When testing, we turn off various optimization options and restore the default settings. We input the standard signal of 1080P through HDMI, and preheat the instrument and TV.

From the test results, the 46B750 has enough brightness, high contrast is also the consistent feature of Samsung LCD screen, and the energy consumption efficiency is also excellent. After the frequency doubling is turned on, the dynamic definition can have a great influence on the human eye, and the movement of the test line is clearer. But frequency doubling technology can't change the LCD delay, so the tail becomes clear.
The performance of brightness uniformity and color gradation restoration is very good, and the performance of mature backlight technology is always reassuring, which is difficult for LED backlight, especially for ultra-thin model side shot design.
The performance of Samsung LA46B750 is satisfactory to the author, plus extremely rich functions and attractive design. If a female host takes a fancy, the male host duck can choose with confidence. In addition to being competent for digital and analog TV, high-definition disc players, set-top boxes, game consoles and so on. Can play the biggest effect. Balanced performance in all aspects is the author's feeling about the restoration of Samsung TV image quality, which is true and clear, but it seems to lack its own image style, which may be the best among Japanese brands.
