Sony’s great surprises to the world of entertainment are always so special and unique. They never fail to find out the trend in need and technically well-versed team tries hard and proves themselves to the highly competitive market which gets updated every now and then that they pioneer the products known for its quality and modernized features. The recent launch KDL-40EX723BU 40-inch 3D TV has packed with lots of brand new features such as Skype, 3D and full HD ready picture quality.
The Sony Bravia series are always found in higher priority when we have an idea to go for a better one. Sony Bravia KDL40EX723BU is a 40-inch widescreen 3D TV brings home a higher level of multimedia experience. It is a full HD television with 1920 x 1080 pixels with 16:9 aspect ratio and refresh rate is just 100Hz including the backlight scanning. This model features Freeview 3D, full size HD 1080p, 3D ready, digital tuner and of course Wi-Fi enabled. And its DLNA compatibility makes the device access into internet services and simplifies watching our desired movies. It is a smart TV, so that we can make calls through Skype. Basically Freeview 3D LCD TV is most supportive for 24p cinema which produces the theatre-like experience as it is at home. The S-Force front surround sound technology delivers highly qualified 3D surround sound effect. The LED backlight improves the image quality to match them to most natural look and it senses the lighting in the room and adjusts the brightness of the picture by design. The ultra slim technology not only added the compactness but definitely the feel of advancement.
- Good 3D images
- Good 2D performance
- Very good motion handling
- Inconsistent backlighting
- 3D is missed if we just tilt our head
- Slow navigating web content
The advancements of the technology force almost all the well-known brands to deliver their product in the same range and leave no time to analyze the good and bad of the rivals or the previous products. The previous edition 32EX723 happened to face cold comments for the not so good 3D picture and we hope for some betterment this time. Before moving into the overall performance and features, we will discuss Sony KDL 40EX723 model’s more successful areas at first. The overall design and finely improved changes from the previous editions are really appreciable. Aesthetic lovers would be pleased by the fine narrowness of its curvy bezels and excellence in finishing style. The grey shade at the bottom edge gets richer with the other three shiny black shades. The stand is a regular type like the one we normally found in the computer monitors. It is widely attached to the base of the TV. And it just settles down flat and perfect on a table. There is a lot to be done in case of hanging the TV on a wall. Yes, many connections in the rear have to be connected and 3 HDMI ports and the RF input would be obviously out in the rear of the TV. So that we have to channelize the cables in order to hide from the view.
We can say that the connections in KDL 40EX723 are well thought of for a 3D TV. There are four HDMI ports of v1.4 version, two USB ports and an Ethernet port. Through the two USB ports, we can record from the TV’s integrated Freeview HD tuner and also play music, video files and even photos from the USB mass storage devices and via Ethernet port it is much easier to access the latest Bravia internet video service. There is an option that we can turn the TV into Wi-Fi enabled if an extra dongle is added to one of the ports.
Sony’s on-screen menu is redesigned in the present year edition. The xross media bar shortly known as XMB interface is retrieved as it is but there is some change how it appears on-screen. It is not the over the TV image instead of that the present footage functions are given just a box space in the top-left corner of the screen arranged horizontally and main menu options are arranged vertically in the right of the screen. To the matter of fact, the sub-menus are not modified and it is displayed as it was before. It is easy to use the menu options without much thought process, still the detailed functions complicates then and there and that makes us feel that it could have been bit easier. The main menu contains fundamental and the most familiar controls as well as includes the new options such as dot noise reduction, which instructs the video processor to find and remove dot crawl which normally happens in the edges of the old composite videos. We know that the composite videos are compatible and can be reversed for black and white TVs. Sony’s this dot noise reduction works on the input signals perfectly despite the signal types.
Controls and Settings:
There are four preset options for fixing the Motionflow system like smooth and standard, clear and clear plus. We can even turn off the feature completely. For film mode setting, Auto 1 and 2 are also manually disabled. In advanced settings surplus video processing adjustment settings are displayed. Colour exaggeration is useful while adjusting white balance. Detail enhancer keeps the highest frequencies stronger in the images after they are upgraded to HD version that is this would provide the additional details for the second platform images where they are normally left unnoticed in the usual play mode. Overscan is fixed by default or we can say it is turned off with 1080i or 1080p level holding the highest quality image which avoids unnecessary cropping and scaling. Web browsing application occupies the entire screen. Sony offers Qriocity and Internet content; they bring out the quality audio and video from different online services. One more essential internet oriented application is for sure the Grace Note Track ID service by Sony KDL EX723 40 3D. Supposing that we like a track or a song which plays in the TV and if we want to find out the track, just by pressing the Track ID in the remote would help the users to find it.
3D Picture Quality:
In terms of picture adjustments we have more than what users look for, we can say it is unusual to see this many options in the row. For example, noise reduction has been parted into three separate sections like normal, MPEG and then dot. Processing options are listed in the advanced menu for adjusting black levels, sharpness, edge presentation and colours, following this motion processing level can also be applied and many more on the list. Watching HD does not require almost of these to be turned on or adjusted. We find that the advanced contrast tool and the black level booster are often at need even though they are preset in the low level. TruMotion settings are worth experimenting and standard settings would help improving some kind of footages especially footages related to sports. We found that performance of 40EX723 3D is at the satisfying stage since it was not the same with the previous edition, the 32EX723.
We normally come across a single problem not yet sorted out is crosstalk; it exists in almost all the 3D TVs. We discuss this in detail in the following heading. Crosstalk is badly present here too. Because of which any sort of 3D image with minimum depth looks only out of focus and fatiguing and one more issue is that time after time we see double ghosting around almost all the objects in the background and some in the foreground as well. We consider sometimes this truly spoil the thrill in watching the 3D scenes. In brief, 3D delivery of 40EX723 is not appreciable since it has a lot of blurring effects of crosstalk on background images which reduce the depth and sharpness to a larger extend. 2D Performance here is thankfully so good. Viewing 2D HD brings out what lacked in 3D like depth and sharpness in detail.
High Definition (HD):
Before moving on to positive aspects, it is better if the flaws are discussed first. A slight strange way of display mode that is the LCD panel of this HDTV is what causes some discomfort. It is usual in LCD displays to have some horizontal lines while sitting close to it, but here we face some vertical lines appearing on some footage on its fast motion. For 2D programmes, it is not that noticeable, but it does matters while dealing with 3D contents. Yet, the ultimate result of the images leaves us happy and satisfied when compared to displays in the rival products where they have some setbacks like saturated colours like deep black, red and blue are always blurred. The LED display displays the images in natural depth and detail. There is never a sign of motion jerk during 2D play and that sounds good.
Sony KDL 40EX723 does not lose its strength in 3D. As we discussed in the 3D picture quality section, crosstalk is a significant problem in 3D TVs. Still, this cannot destroy the entire 3D effects and the experience. There is some strange in the way how the LCD panel is dealt with which is discussed in the previous heading. That becomes the reason for the vertical lines to appear on the fast motion footage. As we see, the present display technology has to face the increasing demands on stereoscopic 3D TV to avoid the visual irregularities. So, it is not just KDL 40EX723 LCD model alone in this aspect. Grey scale tracking is one of the best qualities in this edition while watching 3D shots and reaches the perfectly natural and tint free 3D shots. It has excellent results in cinema mode and here is the right place to say that Sony’s 3D glasses are exceptionally good. Watching 24fps (frames per second) blu-ray movies are perfect to watch. The KDL 40EX723 reinvented 50Hz input does not sound so good. Considering 3D scaling Sony’s 3D televisions have never faced any problems so far.
Once we configure the HD TV’s brightest white reaches as close as 130cd/m2 and the deepest black measures exactly 0.05cd/m2. This really sounds like a good figure which means if we watch the LCD in a completely black room it would be brighter than the other pioneering LCDs in the market.
On the whole, this model leaves us happy in the level of performance with SD video formats. It is especially good in slanting interpolation which means it clearly avoids getting uneven or rough edges while converting the standard def 480i or 576i and also HD 1080i to progressive scan format which of course plays a crucial role when played on the LCD display. Film cadence detection performs effectively. This feature is important when expects to watch movies on broadcast TV. Scaling in this model show us positive sign and produces clear and sharp result with negligible amount of ringing while performing transitions. Generally, we are equally happy with the performing capabilities of KDL EX723 model with the available contents. We obviously expect the best resolution output and here the detail enhancer and also the MPEG mosquito noise features strongly emphasizes high-end frequencies in the video signal in order to produce the higher resolution. The additional control feature for sharpness brings out a lot of more on adjustment. To avoid obvious ringing on the standard definition stuff, we could go with half of the possible setting. X-reality processing engine does not seem to meet the promises made we guess. Filtering process which suppose to smooth the blocked edges and subtle the mosquito noise produced. Of course in Sony it effectively works yet it has somewhat artificial effect on the images just like in any other rival products.
Sony KDL 40EX723 is equipped with X-reality picture engine and that supports the model to produce quality rich and the best standard def performance on up scaling the resolution of the images almost accurately and naturally. A brilliant output through up scaling makes even the poor quality digital telecasting stream and not so good content like some recorded crime investigations and home bound video stuffs become pretty better and matches the best quality of standard def source content. One more excellent performance is that of black level in the TV, here it successfully maintained to produce the ink-touch black colours gets applause. We can have better black effect if we could maintain backlight in the low volume. There is some negligible amount of backlight inconsistency in the corners of the screen during deep dark scenes where setting backlight in the high volume makes it still worse. No colour looks dominant thus they are so natural in result. One setback is that of motion, it is not as sharp as we think. We would not happen to see any judder problems, because TruMotion is quite brilliant in removing the occasional judders in the picture. As we discussed, the resolution seems lacking in fast motion. The users’ audio experience in the KDL 40EX723 would be only a bit ahead of average.
On the whole, the expectations of users would be fulfilled in 2D version. It is brilliant work of the specialists being part of Sony’s banner have brought out a perfect LED edge-lit LCD TV. The issues to be considered are two in the row, one is the deepest black turns out purple shaded and second one is lack of resolution during fast motion. And we cannot avoid mentioning that crosstalk causes some deficiencies in 3D content. It becomes an issue if the users are looking forward to use the TV thoroughly for 3D streams. There is no colour saturated images and red, blue are as natural as they are despite being so rich in brightness. That just continues in 3D sources too. Sony’s KDL 40EX723 can be easily configured to any 24p blu-ray footages into a cinema smooth stuff without any unnecessary video process forced deliberately on the picture and that results in praiseworthy motion clarity. It is so impressive considering its black level and its standard def performance.
