LG 65UH8500 and 65UH7700 are part of LG’s 2016 SUHD TV lineup. Super UHD means it offers more stunning picture quality than UHD lineup especially in term of color performance. One of the advantages is both of them already support two HDR formats at once, HDR 10 and Dolby Vision. This mean, you can play HDR contents in HDR 10 r Dolby Vision on LG 65UH7700 or 65UH8500. In the market, both of them are sold with difference in price about hundreds of dollars  where 65UH8500 as a higher series sold more expensive. So, what are their differences between them and which is a better choice between them?

Differences

If we see on comparison table above, there are only two points that become differences between LG 65UH7700 and 65UH8500. First is about 3D technology and the second is about the number of their audio channel. Lets we discuss one by one.

3D technology is the main primary difference between LG 65UH8500 and 65UH7700. In this case, 65UH8500 is powered by passive 3D technology while there is no 3D technology behind 65UH7700. This makes 65UH8500 is including a few TVs that comes HDR compatibility and 3D technology at once. Out of their difference in 3D technology, 3D performance offered by 65UH8500 is very great. With passive 3D technology, it offers free flicker and crosstalk 3D images with ton of depth. This is a main advantage off passive 3D than active 3D. Additionally, passive 3D also offers many benefits than active 3D on their glasses include cheaper price, lighter and more comfort to use, no need specific 3D glasses for each devices.

The second difference between LG 65UH7700 and UN65UH8500 is about their audio performance. We cans see at comparison table above, 65UH7700 is equipped with 2.0 channel speaker system with total power output 20 watts while 65UH8500 is equipped by 2.2 channel speaker system with total power output 40 watts. This means there is no built-in Woofer on 65UH7700 while on 65UH8500, there are two built in woofer. As the impact, low frequency or bass produced by 65UH8500 is more impressive.  But because their audio system is designed by premium audio system HarmanKardon, this makes their audio performance is above average than most of 4K TV that available in the market. But even so, for listening the music, their audio is still less steady, even for 65UH8500 with built in woofer. This is understandable due to the limitations of mounting the speakers on a thin TV. For more impressive audio sound, the addition of sound bar is still needed for them.

Similarity

The excepting of 3D technology, LG 65UH7700 and 65UH8500 come with many similarities. Picture Quality, HDR, Motion Control, UHD Up-scaling and Viewing angle, both of these TVs offers same performance about them. As a mid class, of course the performance that offered by them are not as great as performance offered  by the series above UH9500 or OLED TV lineup,  but for their price range, they are including a TV that offers complete features with very satisfactory performance.

Picture Quality

Because HDR becomes the main focus in 2016, this would be better if we discuss first about HDR performance offered by both.  This is not about their difference because in HDR, the performance is almost identical. But this is about how great their performance in displaying HDR contents on their screen.

As mentioned, LG 65UH8500 and 65UH7700 are claimed support two format of HDR, HDR 10 and Dolby Vision. But before we discuss about their HDR performance, we will discuss first about HDR 10 and Dolby Vision.  There are many important points about the differences between HDR and Dolby Vision including deep black level, peak brightness, color gamut, depth of color, and how the metadata is sent. We will not discuss the differences between HDR 10 and Dolby Vision because it will be out of focus and too long. But essentially, HDR 10 set 0.05 nits black level, 1000 nits peak white, 90% DCI P3 Color space, and 10 bit depth of color as its standard value that should be met by HDR TV while Dolby Vision set higher standardization that is 4000 nits peak brightness, Rec.2020 Color space, and 12 bit depth of color.

For maximizing HDR performance, LG 65UH8500 and 65UH7700 is powered by HDR Super w/ Dolby Vision as HDR processor and the number of LG’s advanced technologies like Tru Black Panel, Ultra Luminance, Local Dimming, and others. But according a reliable unofficial source, both LG 65UH8500 and 65UH7700 only can reach 0.088 nits of black level. This value is still far from 0.05 nits set by HDR 10 or that reached by Samsung SUHD TV with 0.015 nits of deep black level. Otherwise, while HDR 10 set 1000 nits or Dolby Vision set 4000 nits for peak brightness, both 65UH7700 and 65UH8500 only can reach about 550 nits of peak brightness. Compare to Samsung SUHD TVs lineup that reach up to 1500 nits of peak brightness. Of course, this values is also still far below standardization set by UHD alliance. But we must remember, both 65UH8500 or 65UH7700 is an IPS TV, so peak brightness and back level achieved by both can be said great and much better than most of IPS 4K TVs. As we know, the downside of IPS panel is it makes black level deterioration in dark/dimmed room.

LG IPS Panel

Moving on color performance, LG 65UH7700 and 65UH8500 are powered by quantum dot display for delivering wide color gamut. Although they are powered by the some technologies, but what reached by 65UH8500 is slight better than 65UH7700. 65UH8500 can cover more than 90% DCI P3 Color space while 65UH7700 only around 83%. Of course, this will make a bit issue for displaying HDR contents on 65UH7700. For 65UH8500, although it can meet the minimum value of color gamut standardization set by UHD alliance, some competitors like Samsung SUHD TV offers wider color gamut that certainly will offers better color performance. Moving on depth Color, according to the official websites, LG 65UH7700 and 65UH8500 are already supports 10 bit panel. This means they deliver about 1.07 billion color that makes gradations of color is finer than 8 bit panel. But even so, according to a reliable unofficial source, both 65UH8500 and 65UH7700 is 8 bit panel + dithering.  I don’t know which one is the true. But as long as there is no issue of gradation color when processing 10 bits color, this is not big problem. And the result is indeed much better than tru 8 bit panel and there is no big issue when processing HDR signals.

Overall, the performance of LG 65UH7700 and 65UH8500 is great for fellow IPS TV when displaying HDR contents but they are not quite enough to match the competitor Samsung SUHD TV or Sony Premium Model. With other words, although both of them already support HDR 10 and Dolby Vision, but their display spec is inadequate for meet the standardization of UHD Alliance or Dolby Vision.

But of course, there is not HDR performance only that becomes main consideration to choose a TV. There are still many aspects that should be considered before we buying TV like viewing angle, UHD Up-scaling, and also Motion Control.  And fortunately, LG 65UH8500 and 65UH7700 offers great performance for these aspects even for certain aspects like motion control or viewing angle, they offer best performance among the competitors in their price range. As we know, the use of IPS panel may make black level deterioration in dark or dimmed room, but in other hand, it offers wide viewing angle where there are no 4K TVs with VA panel can reach. Additionally, LG is also very expert in controlling motion picture. With the same native refresh rate panel, LG TVs including 65UH7700 and 65UH8500 offers better performance in motion control than most of competitors like Samsung or Sony.

Smart TV

Both LG 65UH7700 and 65UH8500 features WebOS 3.0 as its platform. We all know, WebOS is simple, usable, and fast in load time or switching between apps. User interface is designed attractively with strip bar across the bottom of the screen. Entering the third year, LG has overhauled their platform so some issues on two previous versions can be solved. So, if there are some issues like streaming ability on previous version, in this third version, this issue can be solved completely. In addition features and apps provides by previous version like Web Browser, VoD Services, LG Contents Store, there some new additional features like Magic Mobile Connection and Magic Zoom  that makes your more comfort t enjoy. In this version, the number of VOD services like Netflix, Hulu, and other now has support HDR, whether it is HDR 10 or Dolby Vision. And the icon is still “LG Magic Remote” where it has a lot useful functions like “point and click” that makes you more comfort when controlling apps or surfing on the internet.

Conclusion

As mentioned, the primary difference between LG 65UH7700 and 65UH8500 is about 3D technology where 65UH8500 comes with 3D technology while 65UH7700 is not equipped with 3D technology. The others slight differences between them are about the number of audio channels and the color gamut coverage like we have discussed above.

Out of their differences, both LG 65UH8500 are 65UH7700 offers great HDR performance. Black level is deep while peak brightness is bright. I say great in here is for a fellow of IPS TV because if compare to VA TV like Samsung SUHD TVs or Sony Top Models, of course 65UH7700 and 65UH8500 are not quite enough to match them.  But in other hand, it offers wider viewing angle than them and better performance in motion control. The other benefit is about smart TV platform with WebOS 3.0.

Back to this comparison, which is a better choice between them? As mentioned, in the market both of them are sold with a difference in price about hundreds dollar where 65UH7700 are sold cheaper.  With the advantages of 65UH8500 over 65UH7700 on 3D, audio performance, and color coverage, in my opinion 65UH8500 is a better choice moreover in 2016 there is a few TVs that support 3D and HDR at once. With spending about $200 more, you will enjoy 3D and HDR picture in at once. But even so, the decision still comes back to you.
