Samsung UN55KU6500 Review

Samsung UN65KU6500 is part of KU6500 series, the entry level of Samsung Curved UHD TV Series 6. It is a TV with reasonable price but offers complete features required for 4K Home entertainment. Although it is not as great what offered by SUHD TV lineup, picture quality is still one of the main advantages of UN65KU6500 as a cheap TV, let alone it already supports HDR technology, of course this will makes you more comfort when enjoying 4K entertainment in your home.

For processing HDR signals and displaying them stunningly, Samsung UN65KU6500 is powered by HDR premium engine. Additionally, combination of Direct LED Backlighting, UHD Dimming, and Auto Depth Enhancing behind it deliver deeper back level and strong contrast like what required by HDR. In other hand, UN65KU6500 is powered by PurColor technology that makes the picture produced look natural with rich color. It is also equipped with great UHD Up-scaling engine that allows you to enjoy lower resolution contents sharply and detail even for low resolution like SD contents. UN65KS6500 also have very low input lag that makes it is great for playing video games, even for fast reflex video games. And the other interesting thing that offered s about Smart TV where with Tizen OS, it offers attractive and responsive smart TV platform with a lot of apps available.

In addition to lack of 3D technology as its downside, poor viewing angle also becomes a main downside of Samsung UN65KU6500. Although Samsung has claimed that the use of curved panel can improve viewing angle, but the improvement is not as significant as VA panel to IPS panel.

At a Glance about Samsung UN55KU7500

Samsung UN55KU7500 Review

One level above UN55KU6500, Samsung UN55KU7500 is part of KU7500, the curved model of Samsung’s 2016 UHD TV lineup. It also comes with HDR technology and also depends on great performance of HDR Premium engine for processing HDR signals. For delivering deep black level and strong contrast, UN55KU7500 is also powered by UHD Dimming and Auto Depth Enhancing. A bit difference to the lower mode is about its backlighting where it comes with Edge-Lit backlight. This has an impact on black level and black uniformity produced where we will discuss a lot above.

For delivering wide color gamut, Samsung UN55KU7000 is powered by Active crystal Color technology. it is a main advantage of UN55KU7500 to lower model UN55KU6500 where the result it can deliver much wider color gamut than the lower model KU6500 series.  Additionally, for handling motion blur when it is displaying fast moving images, UN55KU7500 is powered by Motion rate 120 based on native 60 Hz refresh rate panel.  And because it has 60 Hz panel, of course when handling motion blur is not as great as the series above with native 120 Hz panel. UN55KU7500 is also equipped with great performance UHD Up-scaling engine. This is still very important for allowing you to enjoy all contents in 4K resolution considering most of the contents that available in the market still have lower resolution than 4K. And like lower model KU6500 series, it also equipped 3 HDMI ports with low input lag, so it is a ideal TV for playing Video Games which required low input lag like fast reflexes games.

And as its smart TV platform, Samsung UN55KU7500 also features Tizen OS as its smart TV platform and powered by a quad core processor. Its performance is very fast and responsive with simple and intuitive user interface. Additionally, there are also a lot of interesting and useful apps that will makes you more comfort when enjoying 4K Smart entertainment in your home.

The Differences of Samsung UN55KU7500 and UN55KU6500

As we see on comparison table above, there are two major differences between the that makes Samsung UN55KU7500 is sold more expensive than UN55KU6500. The first is the type of backlighting and second is color technology. In this case, Samsung UN55KU6500 comes with direct LED backlight and PurColor technology and UN55KU7500 comes with Edge Lit Backlighting and Active Crystal Color technology. All of these technologies have big impact on the picture quality that produced.

Picture Quality

The impact that is caused their difference in backlighting technology is back level and contrast produced. Samsung UN55KU6500 with direct backlight offers slightly better black uniformity than UN55KU7500 that uses edge lit backlighting.  While about contrast and black level, UN55KU7500 offers slightly better. But these differences are not too significant and can be said similar. UN55KU6500 reach about 0.02 nits of black level with 5000:1 native contrast ratio while UN55KU7500 can reach about 0.018 nits of black level with 5500 nits of native contrast ratio. With very deep black level and strong contrast that produced by them, this makes them a good option if you are searching TV to be used in a dark room.  Additionally, their black level and contrast ratio is also quite dark to display HDR 10 contents fully. As we know, for displaying HDR 10 fully, a TV must reach 0.05 nits or lower of black level. Maybe what reached by them is not as deep as their cousins Samsung SUHD TV lineup which come with local dimming, but with much cheaper price, what offered by them is very great. What reached by them is quite enough to reveal more detail of HDR images in dark scenes at the screen of UN55KU6500 and UN55KU7500.

Samsung UHD Dmming

While both of them deliver black level and strong contrast, peak brightness offered by them is not quite enough to make the picture quality look more consistent in a bright room, let alone for displaying HDR 10 contents fully which need at least 1000 nits of peak brightness. In this case, Samsung UN55KU7500 reach about 340 nits of peak brightness on 100% window and the brightness will dim on smaller window where on 2% window, it reach only about 155 nits. Meanwhile, UN5KU6500 reach about 400 nits of back level on 100% window and n small 2% window, it reach about 188 nits only. This mean, UN55KU6500 offers brighter picture that makes the picture displayed looks more consistent in a bright room than what produced by UN55KU7500. But once again, overall it is not very bright, even still below what reached by LG TV with IPS panel.

In term of color performance, the difference between Samsung UN55KU6500 and UN55KU7500 is very significant and this makes Samsung UN65KU7500 is sold much more expensive than UN55KU6500. UN55KU7500 with active crystal color can deliver about 93% of DCI P3 color space while UN55KU6500 with PurColor technology reach about 92% of DCI P3 color space. Meanwhile, for displaying HDR 10 fully, a HDR TV must cover at least 90% of DCI P3 color space. For UN55KU7500, there is no issues because what delivered by it already exceeds the minimum standardization of HDR 10. But for UN55KU6500, its color gamut is less than saturated for displaying HDR 10 fully. But even so, for displaying SDR contents than require Rec.709 color space, it is quite saturated. Meanwhile, in term of the depth of color that has to do with color gradient, both of them already support 10 bit panel. This means color gradient of the picture displayed on their screen look very smooth without any banding. This should not be a problem for displaying SDR or HDR contents.

DCI P3 vs Rec.2020

With all display specs that offered by them, we can conclude both of them are equally a good TV when displaying SDR contents in a dark room. The picture displayed will look very good that caused their deep black level and strong native contrast. But when used in a room with a lot of lights or windows, their peak brightness is not quite bright. Meanwhile, although both of them already support HDR 10 format, they cannot display HDR 10 contents fully, especially caused their peak brightness that is not quite bright. In this case, because UN55KU7500 deliver wider color gamut, of course it also offers better HDR performance than UN55KU6500.

But unfortunately, because both of them use VA panel type, their viewing angle is poor, even with curved panel claimed can improve viewing angle. The quality of the picture will look to deteriorate started at 20 degrees off center and front. Curved panel cannot do much to improve their viewing angle. You must set your seat so center and in front of the screen if you want to watch TV the best viewing.

Similarities

UHD Up-scaling

No matter it is high-end or entry level, all Samsung 4K TV lineup including UN55KU7500 and UN55KU6500 offer great performance when Up-scaling lower resolution to near 4K quality. The low quality contents like DVDs with 480p look quite good and sharp with straight line in the image doesn’t look choppy. As well as when the source is 720p like Cable TV, the final images up-scaled look better and sharper with al lot of small details are still preserved. Let alone when they up-scale 1080p contents like Blu-Ray Movies, the final images produced certainly looks very sharp without any lost small details. This is certainly very useful considering most of the contents that available in the market still have lower resolution than 4K.

Motion Handling

When handling motion blur, both of Samsung UN55KU6500 and UN55KU7500 are equally powered by Motion Rate 120 Hz based on native 60 Hz refresh rate panel. The result, their pixel response time f course is not as quick as other TVs with native 120 Hz panel. But even so, what offered by Samsung UN55KU7500 and UN55KU6500 is still above average. When they are used for watching contents with fast scenes, motion blur following moving object or fast paced may still be slight noticeable, but for most people, it should not be a big problem. But unfortunately, when displaying 24p movies, their performance is less so good. Judder still appears from any sources of 24p contents even for native 24p contents like movies from Blu-Ray Player. Luckily, most of the people might not notice judder, so this is not a big issue for them.

Connectivity

As their major connectivity, Samsung UN55KU6500 and andUN55KU7500 are equipped with 3 HDMI Ports and 2 USB ports V 2.0. HDMI Ports already support HDCP 2.2, CEC, and more. This is fewer than what offered by Samsung SUHD TV with 4 HDMI ports and 3USB Ports.  But even so, most of inputs/outputs required are still provided like Component In, composite in (AV In), Ethernet, Antenna In (RF), Digital Audio Out (optical), and Analog Audio Out. Both of them also offer low input lag across all sources, even for HDR input. This certainly makes both of them are great for games, even for responsive games that require very low input lag.

Sound Quality

Both of Samsung UN55KU7500 and UN55KU6500 are equally equipped with 2.0 channel speaker system with total 20 watts speaker power. Although UN55KU7500 offers slight better frequency response than UN55KU6500, but their difference is not too significant. Overall, their sound quality is average or even can be said still slightly below average. For watching TV shows which don’t need impressive sound quality or for most people who don’t so care about sound quality, this might be okay. But for you who care about sound quality, you still need additional external sound bar, even low-end sound bar is able to improve their sound quality.

Smart TV

As their platform, Samsung UN55KU6500 and UN55KU7500 feature Tizen OS as their smart platform. It is not much different to the OS of high end Samsung SUHD TV lineup. And to make its performance fast and responsive, they are powered by a quad core processor with a decent memory. Tizen is very attractive and designed easy to use. User interface is designed simple with “a ribbon” on the below across the screen contains most popular and featured apps. Once an app highlighted, the popup window will appear on the top contains suggested contents. Additionally navigating between menus is also straightforward with selecting between apps and loading time of an app is very quick. Talking about apps, there are a lot of most popular apps available like YouTube, Netflix, Spotify, Amazon Prime, and many more. Additionally, there are also Web Browser, Screen Mirroring app called Smart View, Cloud Games Services, Samsung Apps and content store that allows you to download tons of apps, and many more. Essentially, Tizen is smart TV platform with complete apps and features.

Tizen OS Home Screen

As the controller, both of Samsung UN55KU7500 and UN55KU6500 are also equipped with an easy and comfortable remote called Samsung Smart Controller. Unlike most of TV’s remotes, there are not many buttons and no number “button”. Additionally, there is also no pointer function like on remote “Samsung Smart Touch”. This remote has a lot of IR command that allows you to control other devices connected on your TV via HDMI port. There is also built-in microphone that allows you to control TV function with voice commands

Conclusion

As we have discussed a lot above, the excepting of picture quality particularly about color reproduction, what offered by Samsung UN55KU6500 and UN55KU7500 is virtually identical. Their difference in color reproduction makes UN55KU7500 offers better performance when displaying HDR especially about color gamut. But when displaying SDR contents that required Rec.709 space, what offered by UN55KU6500 is quite enough so the impact is not too significant especially for most people with untrained eyes. But even so, although both of them already support HDR, both of them cannot display HDR 10 fully caused the peak brightness is not quite bright. In other hand, when displaying SDR contents, both Samsung UN55KU7500 and UN55KU6500 offer good picture quality especially in a dark room. It is caused they can deliver very deep black level and strong native contrast ratio. But in a bright room with a lot of windows, they are not the best options considering their peak brightness is not so bright, even still lower than LG UH8500 with IPS Panel.

So, which is a better choice between them? As mentioned, in the market Samsung UN55KU7500 is sold about hundreds dollars more expensive than UN55KU6500 and offer wider color gamut. The impact is noticeable when they are displaying HDR contents. Now, the decision comes back to you according to you according to your need and preferences. If your main consideration in buying TV is a cheap TV with good picture quality, of course UN55KU6500 is a better option for you. But if you care about HDR and don’t mind to spend about hundreds dollars more, of course UN55KU7500 is a better option for you. Furthermore, if you want a serious HDR TV that can display HDR 10 fully, there are UN55KS8000 or UN55KS8500 that comes with Ultra HD premium Certification that sold about $100 more expensive than UN55KU7500. Finally, before you decide to choose one of them, there are a lot of opinions from the people who have purchased one of them where you can make as your further consideration.
