Cost-effective high quality Sony HX750 LCD TV evaluation

[PConline evaluation] What is the key to measuring the quality of a TV? Quality should be an unquestionable measure. In the current market, Sharp, Samsung, and even LG-based hard-screen TVs dominated by IPS screens are known for their excellent picture quality. Of course, Sony can not forget this brand, although Sony has almost cleared out its own liquid crystal panel joint venture business, but still has some strength in image processing, so for Sony TV's picture quality Xiaobian still have confidence. This time came to our evaluation room is a high-end flat-panel TV - Sony HX750 series of 55-inch models.

Compared to last year's HX720 series TV, the HX750 is more affordable (55-inch price segment is located in the 8000), while still maintaining the X-Reality sharp image processing engine, quad-speed drive 400 Dynamic Hyun thin LED backlight and active shutter 3D, in addition BRAVIA network video and network applications also provide a certain use, with a high price. However, due to the appointment of the new CEO, Sony has changed the type of business in the past, and the direction of the TV business has also changed. The changes in product outsourcing and LCD TV R&D efforts have made Xiaobian some doubts about the performance of the HX750. With this evaluation article, he hopes that these concerns can be removed.

basic configuration:

Model introduction

From the model point of view, the Sony HX750 should be an upgraded version of the HX720 last year, but comparing the product parameters, the author found that the HX750 has shrunk in many ways compared to the HX720. The HX720 is equipped with the sharp image processing engine PRO, and the 750 is an ordinary sharp image processing engine; conventional low-reflection dark black panels are also not equipped, and this coating on the outer layer of the panel can reduce a certain amount of screen reflection.

However, the HX750 still has a quadruple-speed drive 400 in terms of the double speed function that is highly valued in high-end TVs. The Network Treasure Box and online video features are also consistent with the HX720.

From these points of view, the HX750 is more like a simplified version of the HX720, which significantly reduces the price of the product while reducing some of the less important parts. This move to compromise the market is more and more common in this year's Sony products. It may not be a bad thing for consumers. In fact, there are fewer consumers with such strict quality requirements, and the price is decided. The key to buying behavior.

Appearance details typical Sony simple style

The appearance of the HX750 does not use the HX850, HX950 and other flagship models of natural design, but the use of a narrow border and metal edge of the process, the overall atmosphere is still the kind of minimalist modern Sony TV appearance.

The four sides of the screen are polished black plastic material. The outermost layer has a polished metal edging, with special thickening protection at the corners. The workmanship can be considered exquisite. The BRAVIA logo is still in the upper left corner of the screen border. From the front, the metal frame appears narrow, with small rounded corners at the corners.

The shape of the base is quite simple, a polished black plastic plus a simple cylindrical bracket is all, the rotation angle can be rotated around 20 degrees.

In the LOGO design uses a more conservative mosaic process, Sony LOGO matte matte texture.

The maximum thickness of the HX750's body is 6.0cm (not including the base), which has no advantage over the Korean products. However, the edge-arc-shaped design is visually thin.

The backplane uses a more common engineering plastic, with cooling holes in both the main processing circuit and the heat-generating area. On the label on the back of the HX750 fuselage, it can be seen that it was manufactured and manufactured by Shanghai Sogo. This shows that it was a Sony factory that was originally manufactured in Taiwan, not an OEM product. This has become increasingly rare in this year's Sony products. .

In the interface configuration, HX750 has HDMI×4, USB×2, VGA×1, 3.5mm audio input/output×1, video component×1, AV analog×1, fiber audio×1, LAN*1, and large Some high-end TVs are the same, but also support direct wireless wifi and wifi direct connection function.

The remote controller uses a model similar to the HX850, the RM-SD014, and adds a shortcut key to the SEN Sony Application Center, emphasizing new network application features.

Quality data instrument test

First of all, we use the evaluation room professional instrument for Sony HX750 detailed test, in the test, we will adjust the Sony HX750 to the standard image mode, backlight adjustment to the brightest, we first record the measured data in the following table.

After a professional color analyzer test, we get the color saturation of the HX750 is equivalent to 103.58% of the NTSC color gamut, this data is quite outstanding in the LCD TV, and is equivalent to the plasma TV. The average brightness is 221.66cd/m2, and Samsung TV is not nearly as bright as 400cd/m2, but it is also enough for everyday use.

In terms of ANSI contrast, the HX750 also performed quite well. Since the maximum brightness in the black block does not exceed 0.1 cd/m2, the ANSI contrast ratio was 2396.32: 1, which was the highest in its class.

Under the black screen, since the HX750 is equipped with a side-mounted LED backlight, the phenomenon of uneven backlighting still exists. The reason is that the light guide plate cannot completely spread the light of the side LED 100%, but the problem of light leakage at the edge is very high. slight.

Here we used the macro lens to capture the HX750's panel sub-pixels. The top four sub-pixels are arranged in “Tian”. The bottom is composed of squares and diagonal stripes. Obviously, this is a type of Samsung S-PVA screen ( Originally appeared on the 2010 model). Similar panels were used with Sony's HX920, HX820, Samsung D8000, and D7000 last year. It can be seen that this panel has brought about a very good picture performance, which is not inferior to the previous products. For the price of more than 8,000 yuan, this Sony HX750 has a very good performance, but it needs to be noted that this TV is produced by the Shanghai cable factory and uses Samsung's S-PVA LCD screen. This kind of quality performance. In the market, due to the different batches of products, other panels or foundries may also be used, and different image quality performances may occur. It is necessary to ask the sales staff to ask questions when buying.

Grayscale test real shot

Since the screen shot has undergone the necessary software processing and is affected by the actual effect of the netizens' display, the screen displayed on the screen will eventually differ from the actual effect of the TV. Therefore, the actual effect is based on the author's text description. The author used a Hi-Definition Reference Disc to test the picture quality of the TV. (Because of the different effects of different display devices, you can refer to the editor's main view method when you cannot judge the screen shot.)

The HX750 is capable of displaying all 15 gray scales, with a large gray scale, and good dark and light areas.

In the black level display, we can learn about the HX750's performance on the details of the shadows. The performance of the HX750 is consistent with the data of the color analyzer. This HX750 not only excels in the interpretation of the black, but also the darkness, and the dark details can be clearly expressed.

This is also an image to test the contrast of the HX750. The silk dress of a woman in black can be clearly distinguished from Beijing, and the interpretation of silk texture is in place. The white woman is also distinguished from the background, showing the higher picture quality of the HX750.

High-speed dynamic picture test

Here is more worth talking about is the dynamic performance of the HX750, HX750 has normal, smooth, clear, clear +, pulse these stalls in the double speed function, in which the dynamic performance of the pulse is the most outstanding, but there is a loss of brightness and flicker, There is a kind of visual experience close to the plasma. Intercepting the performance of several gears at this speed, we can see that the HX750 has better dynamic clarity in clear and clear + gears, which can satisfy most high-speed dynamic images.

Color test screen photo

Here are several groups of Blu-ray test disc screens about the colors. The HX750 is more realistic in color reproduction, with a full and warmer color style, and there is no problem of color overflow.

For the restoration of gold, it is a bit green, and the girl's complexion is natural and reddish.

Menu Interface | Power Consumption Test

The main menu of the HX750 still uses the XMA operating system of BRAVIA TV. Simply put, the PS3 is a cross-shaped operation mode. There is a window on the left side of the main menu that can display the contents of the TV broadcast in real time. When the function is selected, Can continue to watch television, very humane. Responsiveness during operation, good animation feedback makes the menu operation process very straightforward.

It is worth mentioning that the HX750 is still built-in rich image quality adjustment options, almost the same as the original emperor HX920 built-in parameters, in addition to backlight, brightness, display mode, there are MotionFlow speed, white balance, HDMI black level, etc. In terms of fine-tuning the quality of detail, the market is only comparable to Panasonic's models.

Power test

The author uses the instantaneous power consumption test method, which is to measure the power consumption values ​​of the six screens of red, green, blue, white, black and color transitions in the standard mode.

Sony HX750 is quite outstanding in terms of power consumption. In the brightest case of backlighting, power consumption also fluctuates within 90W. The fact that the power consumption is reduced by half in the full black screen also indicates that the HX750 has the ability to dynamically adjust the backlight, and thus has certain advantages under some large contrasting images.

Web Feature Trial | Online Video

In Sony's TV last year, some network applications have been added, and the HX750 also inherits these features, such as network video, network box, DLNA, and wireless remote control of mobile devices. However, compared to last year, the HX750 not only has built-in wifi, but also has more applications on the Web Treasure Box, and the remote control has also added shortcut keys for the SEN Web Application Center.

Internet Treasure Box

Let's take a look at this feature of the SONY Social Network, which is conceptually close to a smart TV. However, this is not an open platform. It is closer to the application of desktop widgets in use. After entering SEN, you can see the arrangement of square tile icons like the WP interface. The current applications include Sony Mall, public comment, happy network, web browsing area, but there is no microblog client.

In the normal case, the treasure box can also be presented as a desktop plug-in, shown as a column on the left.

Public comment

Open the public comment client, you can see the plug-in is still on the side of the screen, will not hinder the viewing of television, but the client's function only includes information, can not be purchased directly, as an auxiliary gadget can still be used.

Internet browser

The browser interface of the HX750 still has little change. It maintains a multi-tabbed interface. The T9 input method can be used when inputting the URL. The input speed is still acceptable.

For the compatibility of the page is also relatively good, just open Youku found that it is not compatible with the video playback, use a degree to be a discount.

other apps

Other applications include weather inquiries, Sony News, etc., you can always check the local weather conditions or new applications for Sony's new products and TV.

Network video

In terms of online video, the HX750 supports BRAVIA network video services based on the Wahite content service platform, providing on-demand webcasts and real-time online broadcast of massively updated movies, series and variety shows.

Video content is classified in a comprehensive manner. There are movies, TV dramas, variety shows, education, etc., but most of them are paid programs. The price of most of the movies is 5 yuan, which is believed to be meaningless to domestic users.

Blu-ray high-definition video screen

In the high-definition video test section, the author tested the picture quality by playing a Blu-ray movie disc, and chose the documentaries “Microcosm”, “Fox and Me” and “King of War”. The first is the documentary "Microcosm," which is full of natural environments and rich in color.

Xiao Bian felt that the HX750 was similar to Sony’s high-end televisions in the past. It had a rich saturated color reproduction, and it was warm at the same time. The detailed interpretation of the dark part was good.

Price analysis

Compared to last year's 55HX720 price of over 10,000 yuan, the price of the HX750 can be described as very kind, 55-inch Suning Tesco in the price of 8400 yuan, cheaper than many of the same positioning of foreign TV, such as ES6100, ES7000 and so on. Although it needs to be noted that the HX750 has some shrinkage compared to the 720, it does not have much impact on the main picture quality.

PConline evaluation room summary

It can be seen through the HX750 that Sony’s compromise on the market on TV has clearly slowed down the development of new features. However, this does not mean that the HX750 is not worth buying, at least for the time being in the image processing engine, Sony still has a big advantage. This brings a better dynamic picture and quality performance, while carrying the LCD panel is also a higher level, it can be said that the current Sony TV quality and price of the most balanced products.

Editor's summary: As said before, the HX750 has no new features compared to last year's products, but the outstanding image quality it has maintained has become a selling point, at least to the level of the expensive HX720 and HX820 last year. If you are very concerned about high-speed dynamic picture, but also care about the true color, then the HX750 is worth buying in LCD TVs. The HX750 series is available in sizes 55, 46, and 40. The 46-inch model is also quite competitive.
