Samsung UE65JS9500 4K TV evaluation HDR performance amazing


Samsung calls its own 65-inch JS9500 a "SUHD TV," although this is just a mouthful of marketing rhetoric, but from the point of view of the product itself, this 4K TV does have a lot of strength. .

Nanocrystal technology


First, the JS9500 uses new nanocrystal technology that can achieve 92% of the DCI-P3 color gamut (commercial digital cinema standard). At the same time, its display panel brightness is extremely high, and the peak brightness can reach 1000 nits - this is no one in the TV market in 2015.

These two picture elements are very important for another key function of the TV, that is high dynamic range (HDR) video. This new picture format contains a wider range of brightness, which is a long-term lack of previous home video standards.

However, in order to obtain HDR video capabilities, the brightness range of the TV panel also needs to be higher than normal - this is the purpose of Samsung's key screen technology innovation.

Processing performance


Samsung also developed a new eight-core video processing system for the TV, which is responsible for the UE65JS9500 native 4K panel (3840 x 2160) and HDR color/light processing high processing performance needs.

This processing engine can not only increase HD content to 4K resolution, but also expand the color and brightness of non-HDR content to achieve HDR-like picture effects.

To achieve this level of brightness, the UE65JS9500 uses an advanced backlighting system that allows independent control of hundreds of individual LED position areas behind the screen. This design not only achieves ultra-high brightness, but also does not affect the outstanding black level/contrast performance of Samsung TV.

The combination of local dimming and direct backlighting has dramatically increased the contrast of the screen while achieving such a high two-fold peak without significantly increasing power consumption.

Connection function


Compared to most TVs, the UE65JS9500 sets the connectivity features to take into account future technological developments. This TV uses an external box to provide processing performance and all connections so that users can purchase new boxes for new features in the future. For today's ever-changing TV market, this kind of design makes the future of television even more assured, except that independent boxes may not be able to get along well with your home's existing playback equipment.



Samsung's new Tizen TV operating system is also one of the innovations. The system gave up the burden of full-screen menus and digital displays, making the interface more stylish. Its use of screen space is more efficient. At the same time, it also introduces a lot of animation and practical design features that can help you quickly get what you need. Although users may need to spend some time to get used to it, after that, you will find that this operating system is indeed the ideal way to get content.

HDR content

Currently available HDR content is still very limited. This test mainly uses Samsung's "Fantasy Rafting by Juveniles", "Exodus: Gods and Kings" and "Princes" provided by Amazon Prime. The Mozart TV series.

The two movie clips provided by Samsung are very effective. When compared with the Blu-ray version of the same content, you will find that the difference between them is very obvious, and even make you think that you are watching different movies. The extra brightness, extremely rich color saturation, and deep black provided by the UE65JS9500 combine to achieve a picture that is unmatched by any non-HDR TV.

This is not the only place where the UE65JS9500 is outstanding. The TV’s careful handling of the extra brightness range gives the screen a subtle shade of detail, grey levels and shadow detail, all of which are not visible in non-HDR content.

However, when playing Amazon's HDR content, the performance of the UE65JS9500 is not so good. It not only lacks the dynamic range of previous movie clips, but also looks a little white. However, this should be a problem with the content itself, and it has nothing to do with the playback device. The same effect will occur when using the LG 65EF950V HDR TV to play the same content.

When playing ordinary content, the HDR performance of this TV is not as good as playing native HDR content. However, we can still see that the richness and dynamic range of the screen are still better than those of standard LCD screens. The effect is much better. Although occasionally there is a problem of loss of details in the shadows, the resolution of the playback content does not appear unnatural after it is raised to 4K.

4K resolution

The benefits of 4K resolution can be believed that everyone is already familiar with it. When playing 4K content, the performance of the UE65JS9500 is also superb. Not only is the color resolution amazing, but the control of light is also powerful. Coupled with the 4K resolution itself, the level of detail and Samsung's powerful processing engine, this TV's screen effect is far more than any one 65-inch Full HD TV.

If you still care about 3D and have already paid for Samsung's active shutter glasses, you may want to know that the UE65JS9500's 3D playback capability won't disappoint you.

The high brightness of this TV compensates for the effects of active shutter glasses on the brightness of the screen. The high contrast helps create a natural 3D space, while the resolution enhancement feature allows your glasses to capture more detail on the screen. , but it will not make people feel unnatural.

Some disadvantages

As of now, Samsung's UE65JS9500 seems to be a perfectly perfect TV, but if you have to nitpick, it also has some problems.

First of all, as a common problem with curved TVs, if any bright objects are reflected on the screen, the reflections will be distorted and extended to almost the entire screen. Worse still, the screen coating of this TV is indeed very reflective.

In addition, if your viewing angle is more than 20-30 degrees, the curvature of the screen also causes image geometry problems. But on the bright side, if you are sitting in the middle of the screen, this curved screen can really improve the immersion of the movie.

In another problem, although the overall performance of the UE65JS9500's direct-type LED backlight and local dimming system is excellent, it sometimes causes an aperture effect around bright objects, especially in HDR mode.

to sum up
Although the Samsung UE65JS9500 is not a perfect TV, if you can avoid the problem of screen reflection, then its picture quality performance can definitely cover up those defects.

The HDR function of this TV is amazing and it also has the brightest screen of the year. With the help of a series of advanced features, Samsung's flagship TV seems to give a glimpse of the future of television technology.
