The Samsung JS8500 is currently our second-best rated LED TV in 2015, thanks to its overall great picture quality. It's only real issue is the degradation of quality at an angle.
Thanks to its good gray uniformity, the Samsung JS8500 SUHD TV has the second best overall picture quality that we tested in 2015 for an LED. It doesn't have a local dimming as effective as the pricier JS9500, but it has a better uniformity. If this TV is in your price range, look no further. This is the TV to buy.
The Samsung JS8500 feels higher-end than the cheaper JU7100. It is thinner, but the borders around the screen are thicker.
The stand is nice and stable, and not too wide relative to the screen. Most people shouldn't have a difficult time fitting this TV into an existing setup.
The native contrast ratio is good. Because we use a checkboard pattern, the local dimming didn't affect our measurement.
The LEDs are on both sides of the TV, which in conjunction to turning on 'Smart LED', creates horizontal blooming. The zones are quite big, but at least it is useful to darken the letterbox in movies (feature called 'Cinema Black').
The maximum luminosity of a 2% white window is 526.9 cd/m2, which is, of course, less bright than on the JS9500. You can also see a lot more blooming due to the edge lit local dimming.
The JS8500 has the least dirty screen effect of any LED TV we've reviewed this year. We measured it at 0.147%. Of course, there are still some darker areas (it has a standard deviation of 2.454%), but it is one step above every TV we reviewed in 2015.
This is thanks to Samsung's good implementation of an edge-lighting backlight. Last year's H7150 had a similar backlight, and uniformity, too.
The picture quality degrades if you watch it from an angle. The colors desaturate and the blacks become gray. Of course, you can still see the picture, but it won't be as good as in front.
Update 01/06/2017: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results from 2016 TVs.
If you set 'Colorspace' to 'Native', the color gamut covers 13% more of Rec. 2020 than the JU7100.
It is excellent at keeping the ambient reflections under control. Keep in mind that it has a glossy finish though, so direct reflections are a bit worse, with a little bit of glare around them.
It can get very bright, which is great with a room full of windows. However, due to its glossy finish, it isn't ideal for situations where the window is directly facing the TV.
There is no judder in movies when using a 24p source (like a Blu-ray player). Sometimes it can do the reverse 3:2 pulldown, but not always, so you might notice a little bit of judder in movies when watching over a 60p or 60i source (like on cable). You can get rid of it when using 'Auto Motion Plus', but this adds the soap opera effect, which not everyone likes.
The input lag in game mode is 36.9ms, which is average-good. You won't notice it in video games.
Like all Samsung TVs, the JS8500 doesn't support 1080p @ 120 fps. It does however display 4k @ 60Hz @ 4:4:4, when setting the 'Device Type' of the input to PC and turning on UHD Color.
The bass extension is good for a TV and so is the frequency response at lower volumes. But at higher volumes the frequency response suffers due to the compression and pumping artifacts. It does however get relatively loud.
Major Apps Available
Overall, Samsung's Tizen OS is a good smart TV interface, and the voice and motion control on the remote make browsing the web (and your app collection) a breeze.
It would be nice if the remote had a keypad on it, just so that manually changing channels could be a bit quicker. The guide function works well, though, so a quick setup of that feature will have OTA watchers all set.

Hello! Great question, we have looked at the 24-inch mode during testing and found that it seems to downscale 1440p making things like text slightly blurry, the monitor stayed responsive even in 24-inch mode. Text remains the clearest at its native 27 inch.
Do you have any idea what the actual 24 inch display resolution is per chance. I’ve looked everywhere asked LG several times and can’t figure it out. Its between 1296p and 1314p. But between those resolutions there are no resolutions divisible by 2 or leave the height as 16:9… totally lost
Fwiw, you can change the resolution to 1332p480hz while in the 24” mode just as easily as you can with other resolutions.
the 24 inch mode is not 1332p though. Its somewhere between 1296p and 1314p. Between those resolutions there are no 16:9 resolotions that are divisible by 2 though. I’m totally lost to what this resolution actually is and I have no idea how to find it, extremely frustrating as I have asked LG support at least 5 times and they’re all utterly useless outsourced morons that don’t actually know anything about their own products.
Hi there! Was wondering if you guys tested out the 24 inch mode? Strangely there are very little reviews or information about this monitor online, which is a little bit frustrating. I had to find a billi billi review in chinese that discussed the 24 inch mode. The manual, nor lg support are able to tell me what the actual resolution of the 24 inch mode is, unless it is infact just downscaling from native 1440p with post processing which sounds AWFUL. In the billi billi review, it mentioned that the monitor had blur on this 24 inch mode, I would really love and appreciate an analysis on the 24 inch mode, is it as crystal clear as the 27 inch mode? Is there a 24 inch resolution in the EDID of the monitor to use for said mode, and is it blurry if you guys are able to manually calculate or find the resolution at the 24 inch mode? Would mega appreciate it, thanks for the great review.
