The Samsung JU6500 is a good and reasonably-priced 4k LED TV. However, it has a few flaws, like judder in 24p content and a loss of saturation at a wide angles.
The Samsung JU6500 doesn't look like a budget TV. The borders are small and the TV is quite thin.
The stand is very sturdy, and the footprint dimension is average.
The contrast is decent, as is the uniformity. This TV can't play 24 fps movies without judder, though. If you love watching Blu-rays, DVDs, streaming movies, or other 24 fps movies, you should go with a different TV.
You also don't get advanced features like local dimming, HDR, or 3D with this TV.
The contrast ratio is average. The blacks aren't as deep as you get with some other LED TVs, but they're still dark enough that it shouldn't be a problem.
The DSE is reasonably low, and the deviation in the uniformity, while bad, is better than much of the competition.
The picture doesn't maintain its color accuracy at an angle, which isn't ideal if you have multiple viewing positions.
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.
The black uniformity is good. No flashlighting. A little bit of clouding, but it isn't noticeable with normal content.
The JU6500 has a semi-gloss screen finish which doesn't reflect a lot of light. A few overhead lights won't be an issue.
It's capable of about average brightness, so it should be fine in most situations.
This TV is a great budget 4k option for watching sports. There's little blur, and not too much of the patchiness that can make playing surfaces look bad.
If you want a mid-range TV just for watching sports, there's no need to buy a more expensive Samsung set. This one will work fine.
The Samsung JU6500 is pretty good for motion blur. If you want less, you might want to upgrade to the JU7100.
This TV does not display 24p properly, even though it accepts it as an input. You can see judder when watching movies. It is a small and consistent judder though (called 3:2 pulldown), so not necessarily a deal breaker for most people.
At least, you can turn on 'Auto Motion Plus' to add the soap opera effect to get rid of it.
The little amount of blur also means that fast movement in video games will look great. That, combined with the minimal delay between making an input and seeing the reaction onscreen, makes this a great gaming TV.
When 'Game Mode' is turned on, the input lag of the Samsung JU6500 is low (26.5 ms). Under PC mode, the input lag is 48ms.
To achieve Chroma 4:4:4, enable UHD Color and label the input as PC.
This TV can get loud, and the bass is okay. The accuracy of the sound isn't particularly good, though, and the sound gets a bit too distorted at louder volumes. There's not too much distortion at low volumes, though.
Note: Sound Quality test for TVs reviewed before 2017 was performed at 75dB, 85dB, and Max SPL. Starting 2017, the target SPL levels have been changed to 70dB, 80dB, and Max dB SPL.
OK low-end cut off for a TV, and it does get loud too. But the frequency response is poor, especially at higher volumes. Pumping may be present.
Good distortion at lower volumes, but there is a moderate increase in distortion as the volume increases.
The app selection is limited, and it doesn't have a fancy remote. There is a built-in web browser.
The TV comes with just a basic remote, which isn't a user friendly device for using the built-in web browser.
