We started by selecting the Film Picture Mode and adjusting the Contrast, Brightness and Sharpness controls. We selected a Color Tone of Warm2, a Colour Space of Auto and left the Gamma at cypher. The out-of-the-box performance was reasonably good, with gamma tracking at two.2 and the DeltaEs (errors) measuring between two and 6. Whilst these errors were visible, the result of a slight excess of green in the greyscale, they were simply pocket-size. The color gamut was besides very good, with all the colours measuring close to their targets and excellent accurateness in terms of luminance. There was a minor error in the hue of red and a slight over-saturation in green only overall this is an excellent out-of-the-box performance.
The S9 includes both a two- and a ten-point white rest control and it was relatively easy to adapt the greyscale using the two-point and and so fine tune with the 10-point. The consequence was reference greyscale, with errors that were less than i (well beneath the threshold of human perception) and a gamma that nonetheless accurately tracked 2.2. For reasons best known to Samsung, when you select the Custom Colour Space it defaults to the panel’s native gamut which is pretty large. That ways yous take to practise a off-white amount of correction with the CMS, specially in green and cyan, to go the colours back to Rec.709. All the same once yous have, the S9 can evangelize a reference color operation too.
When we measured the tracking at saturation points below 100%, it was a different story and clearly having to adjust the native color space and then much using the CMS had affected the lower saturation points. This is i of the reasons that nosotros run this test because 100% saturation doesn’t give you the whole picture. Since the Auto colour space was already very accurate, we reverted to that and found that tracking was much improved. Every bit a effect we would more often than not recommend calibrating the greyscale and and then using the Motorcar colour space setting. The images produced have a lovely natural appearance and any errors are below the threshold for human vision.
If at that place is one surface area where OLED has been expected to deliver, it’s in terms of blackness levels and the S9 certainly lived up to its billing hither. We measured blackness at 0.000cd/m2, and so essentially if the S9 was putting out any light our Klein K-10 was unable to register it. The S9 was likewise very vivid, easily hit the 120cd/m2 that we use equally a target for our critical viewing tests. That means that technically the S9 has an space on/off dissimilarity ratio, although as we all know it’due south the ANSI contrast ratio that really matters. Well the S9 blew that out of the water as well, as the graph beneath demonstrates. We’ve never seen measurements that good and the resulting ANSI contrast ratio was 71,000:1! The S9 sets new benchmarks when it comes to black level, contrast ratio and dynamic range.
We were also pleased to see that the screen uniformity was excellent with no low-cal pooling or bright edges. In fact the S9 delivered a wonderfully consistent prototype that was complimentary of any of the annoying issues that so often plague LCD and plasma TVs. So there was no banding, haloing or dirty screen issue, nor were in that location whatsoever expressionless pixels – which is just likewise since Samsung annunciate the S9 under the banner “life in every pixel”. Distressing Mark merely I idea I’d get that gag in first. There have been reports of prototype retention and screen burn with OLED TVs but in that location was no evidence of this on our review sample. Equally with plasmas there is a screen burn protection feature in the menu that brings up a screen saver later a specified menstruum of time. Every bit far as the lifespan of an OLED Goggle box is concerned that remains to be seen but Samsung are confident this won’t be a problem. One other well reported outcome with OLED is that blue decays faster than both red and dark-green. To combat this, the blue sub-pixel is twice as large as the red and green ones – again Samsung are confident this will address the issue.

The video processing on Samsung TVs has always been impressive and the S9 continues that tradition, never putting a foot wrong in our tests. Information technology had no problems deinterlacing and scaling standard definition content, with excellent item and no unwanted ringing. The S9 besides had no problems detecting both 3:2 and ii:2 cadence correctly and, as long as the Auto2 Film Mode was selected, scrolling video text over motion picture was too delivered perfectly. The S9 performed superbly in all the other tests every bit well, delivering an near flawless performance in every regard. The quality of the video deinterlacing at 1080i50 was simply as good every bit information technology was for standard definition and at that place were no apparent issues with 24p content. There were likewise no signs of clipping in blood-red, light-green or bluish; whilst we could come across all the detail upwards to video level 255 and down to video level 17.
The 1 area that did surprise united states of america was motion handling. Given the incredibly fast response times of OLED, we had expected motility to take a more plasma-like advent only in actual fact it was very LCD-similar, delivering well-nigh 300 lines of resolution with Motion Plus off. Co-ordinate to Samsung the reason for this is that the OLED pixels are driven using a method called ‘sample-and-hold’ which, as the name suggests, displays and holds a static frame until the next one is refreshed. Since our eyes are always moving when tracking moving objects, this approach causes the held frame to mistiness beyond the retina. The flicker of an impulse-driven display like a plasma or a CRT shortens the frame samples and, coupled with the natural phosphor disuse, eliminates motion mistiness. Samsung claim that ‘sample-and-concord’ is used because otherwise the motion on an OLED screen appears unnatural to the homo centre.
The only way to reduce motility blur acquired by ‘sample-and-hold’ is to shorten the amount of time the frame is held for – either by extra refreshes or black frame insertion. Within the Motion Plus control Samsung offer both options with frame interpolation existence used to increase the refresh rate. If you lot choose Custom and then plow Articulate Motion off, you can adapt the Deblur and Dejudder controls to produce excellent motion handling without introduce unnatural smoothing. This is especially effective with fast-paced sports activeness. If you lot plough Clear Motion on that turns off the frame interpolation only introduces black frame insertion instead. This arroyo immediately reduces the brightness of the epitome, although you can easily adjust for this but it as well results in increased flicker. Whilst the flicker wasn’t really an issue, Articulate Movement does disable 24p playback which is not platonic for Blu-rays and for movie-based content we generally left Movement Plus off because we yet felt the apply of frame interpolation resulted in the ‘soap opera effect’, even so mildly.
Nosotros measured the input lag at 146ms with Game Manner off and 62ms with information technology on. Nosotros managed to shave a couple of milliseconds off this by renaming the input to PC but fifty-fifty 60ms volition be too high for a serious gamer. However for those of us with less-than-cat-like reflexes, gaming on the S9 proved to exist very enjoyable. The images looked gorgeous and the move handling was great (especially with Motion Plus engaged), resulting in a highly enjoyable tour of commotion on
GTA5. The superb 3D on the S9 was very evident during a prolonged session playing
Wipe Out, with the brilliant image and deep blacks making the experience more than immersive than ever before.
The following measurements were taken with a full screen 50% white pattern:
Out-of-the-Box – Standard Way: 136W
Calibrated – Motion-picture show Mode: 137W
Calibrated – 3D Mode: 175W
The S9 simply blew u.s. away with some of the best images we have ever seen.
