What is the JS9500?
The JS9500 is intended to be a statement product and only comes in very large screen sizes. In the fact the smallest is the 65-inch UE65JS9500 that we reviewed recently and the largest is the 88-inch UE88JS9500. Our review sample is the equally monumental 78-inch UE78JS9500, which will set you back a whopping £9,999 at the time of writing (May 2015). Obviously the 78JS9500 is beyond the means of most people but does this aspirational product provide a glimpse of the future?
Connections & Control
The box itself mirrors the rest of the TV with a silver brushed metal finish and a well built feel to the unit. The first generation of the One Connect box could get quite hot due to the processors inside but Samsung managed to address that issue last year. Obviously with Octa-Core processing in this year's model, the amount of heat produced has increased and Samsung have included fans for cooling. Although we should point out that you can hear these fans when the volume is low or off.
The smart remote includes navigation buttons and a pointer for effective motion control of all the smart features on the 78JS9500 but as an alternative there is also a free remote app available for both iOS and Android. This app is well designed, with a slick and attractive user interface and includes all the controls you will need to control the TV. Whilst there are already two other ways to control the JS9500, the ability to use your smartphone or tablet as a remote is a welcome addition

Pre-CalibrationSo far this year, all the Samsung TVs we have reviewed have been extremely accurate out-of-the-box, so we were surprised that the UE78JS9500 didn't deliver better measurements. That isn't to say they were bad but there was a deficit in blue across most of the greyscale, which meant the excess of red and green was giving whites a slight yellow push. Although the gamma was tracking at 2.2, aside from a slight bump up to 2.4 at 10IRE. The colour accuracy was better but it was being affected by the errors in the greyscale and you can see white skewing towards yellow in the CIE chart on the right below.
Post CalibrationThankfully correcting the deficit of blue in the greyscale was easy, all we needed to do was increase the blue gain control in the two-point white balance and the errors disappeared. Although the JS9500 also has a ten-point white balance control we didn't really need to use it to get a reference greyscale performance. The gamma is tracking around 2.2, although we couldn't flatten out the bump at 10IRE. Once the greyscale had been calibrated, it was a simple task to use Samsung's excellent colour management system to bring all the colours into line with their target coordinates, again delivering a reference performance.
Samsung UE78JS9500 Video Review
UE78JS9500 Picture Quality
Video ProcessingSamsung have always been very strong when it comes to video processing and on the UE78JS9500 the results were extremely impressive. This remains a key area when it comes to Ultra HD 4K TVs because, for the time being at least, almost all the content you watch will be upscaled to match the higher resolution panel. The 78JS9500 delivered a fantastic all-round performance, scaling content effectively without introducing any obvious artefacts. The JS9500 also passed all of our usual video processing tests and overall the quality of the deinterlacing and scaling was excellent.
Motion HandlingAs always we used our FPD Benchmark test disc to measure the motion resolution of the UE78JS9500 and it came in at around 300 lines which is what we would expect from an LCD TV. This could be improved to the full 1080 lines by using the Auto Motion Plus feature but that gives film content an overly smooth appearance. However there is room for experimentation when it comes to sports or games but in general we found the motion handling on the 78JS96500 to be perfectly acceptable, even on a screen this big. Thankfully when watching 24p Blu-rays the motion retained a suitably film-like quality and overall the motion handling on the JS9500 was generally good for an LCD TV.
Black Levels & Contrast RatioSamsung use VA panels on their TVs and as a result the black levels are generally very good for an LCD panel. We measured a 0IRE window at 0.06cd/m2, although on a full black screen the LEDs switched off and the measurement dropped to 0.001cd/m2. We got exactly the same measurement of 0.001cd/m2 on both a window and full screen with the Smart LED (local dimming) set to Low. The UE78JS9500 is also very bright, easily hitting our target of 120cd/m2 and going as high as 386cd/m2 on a 100IRE full screen with everything maxed out. The on/off contrast ratio came in at 2,000:1 and the ANSI contrast ratio was 1,544:1 with Smart LED off and 1,935:1 with it set to Low. Since the 78JS9500 uses a VA panel it is worth pointing to that the viewing angles are limited when compared to an IPS panel. However thanks to the huge screen size this is less of an issue than it is on smaller models because unless your room is huge, you're never that far off axis.
Ultra HD 4K PerformanceIn our recent review of the 40-inch Samsung UE40JU6400 we questioned the logic of watching Ultra HD 4K content on a screen that small but there are no such issues when it comes to the UE78JS9500. This panel has been designed to represent the state-of-the-art when it comes to UHD and at 78-inches the results are simply jaw dropping. We have test footage of Canada that was shot on a Panasonic GH4 and the images looked simply spectacular on the JS9500. All the elements that make this TV so good came into play with the Ultra HD panel, the full array backlight, the inherent brightness, the image accuracy and the effective local dimming all combining to deliver stunning 4K images.
We also had some test content (scenes from Exodus: Gods and Kings and Life of Pi) that has been remastered in High Dynamic Range (HDR) and again the results were hugely impressive. On the massive UE78JS9500 these scenes in HDR simply looked breath-taking, with incredible detail and highlights that popped. One thing we did notice is that when the JS9500 detects HDR content, it defaults to a backlight setting of 20, which means you'll need to remember to turn it back down again when watching normal content. Although with the recent announcement of the completed specifications for Ultra HD Blu-ray, the future of 4K looks very bright indeed - if you'll excuse the pun.
High Definition PerformanceBy now you should have realised that in the JS9500 range of TVs Samsung have delivered the pinnacle in terms of performance from established LCD technology. In fact it's hard to see how they could really squeeze any more performance out of an LED LCD TV. They will probably reach 100% of DCI soon and if they make sure you can't see the LED array and improve the viewing angles that would be great but otherwise the JS9500 is probably about as good an LED LCD TV as you'll ever see. When you combine all the elements we've already mentioned and then add in the superb video processing, the results with lower resolution content are just as impressive. So when watching Full HD broadcasts the UE78JS9500 delivered lovely big screen images and nature documentaries in particular gained an entirely new dimension.
However the large screen size does mean that any limitations in the source material will be immediately apparent and banding in particular was evident in certain TV channels. Which means if you're watching standard definition, where the TV is interpolating over 90% of that 78-inch image, you're really going to need to employ some sharpening to make the image watchable. Although you won't need to resort to such methods with most Blu-rays and the high definition disc format really got a chance to show what it's capable of on the 78JS9500. Recent purchases like John Wick and old favourites like Gravity simply looked stunning on the JS9500, making you almost believe they were 4K transfers. Until that is you actually put on some UHD content and truly appreciate the potential of the new format.
3D PerformanceWhen it comes to 3D, the bigger the screen the more immersive the experience and the UE78JS9500 certainly delivers the goods in this regard. In fact with its curved screen it's already fairly immersive in 2D, so once you switch to 3D the results are fantastic. The active shutter technology takes full advantage of the increased resolution of Ultra HD panel and the result is a 3D experience that is bursting with detail. The incredibly bright panel means that the dimming nature of the glasses is completely eliminated and there was a pleasing lack of crosstalk or other distracting artefacts. In fact our only complaint is that there is some undefeatable frame interpolation going on, which we have reported back to Samsung. However that aside the results were spectacular and watching the recently released The Hobbit: The Battle of the Five Armies showed a wonderful sense of dimensionality, with plenty of layers and depth. The overall performance of the 78JS9500, coupled with the size of the screen and the curve, completely immersed you in the film and made you feel as though you could step through the screen and into Middle Earth.

Samsung UE78JS9500 (JS9500) SUHD 4K TV Review
The out-of-the-box accuracy wasn't as impressive as we've seen on some Samsung review samples this year but after calibration the 78JS9500 delivered a reference performance. The native blacks are good for an LCD panel and the local dimming is very effective, resulting in a decent contrast ratio and dynamic range. The motion handling was also good and can easily be improved by using the Auto Motion Plus feature. When it came to watching actual 4K content the huge 78-inch screen really came into its own, delivering a gorgeous and incredibly detailed picture. The same was true with lower resolution content, although the larger screen will reveal any limitations in the source content. Thanks to the size of the screen, the curve really added to the enjoyment and created a highly immersive experience which has even more impressive when watching 3D content.
In terms of complaints, our only real issues were that there was occasional banding, the optimal viewing angles are limited, there was some undefeatable processing in 3D and the One Connect box can get noisy. Otherwise the Samsung UE78JS9500 delivered a fantastic overall performance and despite the hefty price tag, it's worthy of a Highly Recommended badge.
