The Samsung K6250 is a mid-range 1080p curved TV. It looks great with a sleek design, and polished metal finish. Unfortunately it only offers average picture quality and lacks features found in higher end TVs to improve this. The motion handling is poor, and input lag is disappointing. At least the smart platform works well.
- Good contrast for dark scene performance
- Poor motion handling
- Higher than average input lag
- Can't get very bright
The Samsung K6250 has a sleek design, which appears quite high end. The borders have a metallic finish, and the four-legged stand supports the TV well. The back is very similar to the high end Samsung KS8500, with the same reflective finish. Although it looks good, it also attracts fingerprints and dust.
The back is sleek, with a smooth and reflective plastic finish. It is very similar to the high end KS8500, but the inputs go directly into the TV instead of a OneConnect box. The inputs all connect sideways, so this should not be an issue for wall mounting.

The Samsung K6250 has an average picture quality. The contrast ratio and uniformity are good, which should provide relatively good picture quality in a dark room. The upscaling performance is also good for watching DVDs or cable TV. The picture quality degrades from the side, and the color gamut coverage is only good enough for SDR content. The peak brightness is bad, and small highlights result in the whole screen dimming. This TV does not have any local dimming feature.
Contrast ratio is very good for the Samsung K6250. Blacks are deep and should provide a good picture quality in a dark room.
There is no local dimming feature available on the Samsung K6250. Video for reference only. There is an auto-dimming feature called 'CE Dimming', but it is implemented directly in the TV software and cannot be control under 'Movie' picture mode. This cause dark scene to become too dark and is generally more annoying than helpful. Under 'PC' mode the 'CE Dimming' is turned off.
The Samsung K6250 has a bad peak brightness performance. The 2% window is extremely dim because of the implemented 'CE Dimming'. Under 'Movie' picture mode, the 'CE Dimming' cannot be turned off unfortunately. All the other size windows remain at around 272cd/m², which is still well under what other mid-range TV can generally do.
The gray uniformity is good for the K6250. On the test picture, you can see the left side is more bright and the right side is more dark. Luckily, the rest of the picture is relatively uniform, which should not cause too much of dirty screen effect.
Viewing angle is average for the K6250. The colors lose some saturation at an angle, but when compared to other TVs with VA panel, the Samsung K6250 outperforms most of them.
Update: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results.
Black uniformity is great. We can still make out a bit of clouding, but it is more evident in our test picture. During normal movie viewing, the clouding is not really noticeable.
The Samsung K6250 has an 8 bit panel. The 8 bit gradations are clearly visible in the darker colors. The gradient does not show any signs of irregular color shades or any obvious banding.
Prior to calibration, the colors are slightly oversaturated and white balance is a bit off, but for most people this should not be an issue.
Calibration is easily performed using the inbuilt 10 point white balance and color settings. It results in very accurate colors, and a good white balance. The gamma drops slightly below 10% to preserve dark details. Our calibration settings can be found here.
The colors of the K6250 are good for SDR content, but it does not support a wide color gamut for those interested in HDR.
The Samsung K6250 can't produce a wide range of colors at different luminosities.
The K6250 is average at dealing with reflections. The semi-gloss finish helps to diffuse reflections. The curved screen spreads them across the screen, but in doing so reduces the intensity of the reflections making them easier to see through. Some rainbow effect can be seen around reflections.
This TV doesn't support any 3D features, just like all other Samsung TVs this year.
Unfortunately the K6250 is unable to handle motion very well. Those sensitive to judder will notice it when watching movies, regardless of the source. The TV has a 60Hz panel, and so can't interpolate 60fps content to any higher frame rate. The motion blur is good, with only a short trail following moving objects.
The response time is good and only results in a short trail following moving objects. The backlight uses PWM to dim, and so flickers at 120Hz. This can be seen in the clear duplications following the logo.
The K6250 is unable to play movies from any source without some judder, but most people won't notice it.
The K6250 has a 60Hz panel, which is able to interpolate 30Hz content. To do this, set 'Auto Motion Plus' to 'Custom' and increase the 'De-Judder' slider.
The K6250 has average input lag, which should be fine most casual users. It is a 1080p TV, and so is limited in the range of supported resolutions. It does support chroma subsampling, which results in clear text when used as a PC monitor.
The input lag of the K6250 is average. Even casual gamers might notice some delay between controller actions and the result on the screen. Label the input as 'PC' to achieve the lowest input lag. With the input labelled as 'Game Console', and the 'Game' special viewing mode the input lag is 53.2ms.
- 20% 1080p @ 60Hz @ 4:4:4
- 20% 1080p @ 120Hz
- 20% 4k @ 30Hz @ 4:4:4
- 20% 4k @ 60Hz
- 20% 4k @ 60Hz @ 4:4:4
The K6250 is a 1080p TV, and so cannot accept or display any resolutions beyond this. It has a 60Hz panel, and so cannot display a 120Hz signal. It does support chroma subsampling though, so text appears clear on all backgrounds. To do this, label the input to 'PC'. The input lag in 'PC' mode is 47.2ms.
All inputs are located on the side, same as the Samsung KU6300.
Sound quality of the Samsung K6250 is slightly below average. The frequency response is a bit better than average, but there is significant distortion at higher volumes. If you care about the sound quality, a cheap soundbar would be an improvement.
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.
Average performance. Maximum volume and low-end cutoff are about average, for a TV. Frequency response is good at 75 and 85. However, at maximum volume considerable pumping and compression is present.
Poor distortion performance. The overall amount of harmonic distortion is decent at 75 and 85dB SPL. However, at maximum volume, there's noticeable rise in harmonic distortion, which may not necessarily be audible in real-life situations.
The Samsung K6250 comes with the latest Tizen smart OS. This is the same platform found in the other 2016 Samsung TVs, such as the KU6300. After turning on the TV it does take some time to load, but is simple to use, and feels responsive when it is up and running. There is a wide range of supported applications available in the 'App store'. It is easy to watch videos or movies with a thumb drive or USB hard drive.
Controls are located under the right side of the TV, same as most of the 2016 Samsung TVs such as the KU7000. They provide basic operations, such as changing the volume, input or channel and are easy to access if wall mounted.
The remote is the same smart remote found with the Samsung KU6300. It is simple and works well.
Differences between Sizes and Variants
We tested the 55" (UN55K6250) version FA01. For the most part, we expect our review to be valid for the other sizes.
If someone comes across a different type of panel or if their Samsung K6250 doesn't correspond to our review, let us know and we will update the review.
Compared to other TVs
While the Samsung K6250 is the cheapest curved TV, it is still priced well above the competition. Other TVs available at a similar price offer 4k resolution, and sometimes other features to improve the picture quality such as local dimming. Keep this in mind when viewing our recommendations below.
The Samsung KU6300 is available for about the same price, but delivers better picture quality and a 4k resolution. It offers better performance in almost all areas. Some people may prefer the curved screen and more premium look of the Samsung K6250, but the Samsung KU6300 is much better value.
The TCL FS3750 is a budget 1080p TV, available at half the price of the Samsung K6250. Despite the price difference, the TCL FS3750 provides similar picture quality and better motion performance. For gamers it also offers the advantage of great input lag. Most people are better off saving the money and buying the TCL FS3750.
The Vizio M Series 2016 is a mid-range 4k TV available for about the same price. It offers much better picture quality, especially in dark scenes due to some premium features such as local dimming. The smaller sizes of the Vizio M Series 2016 have a 60Hz panel like the Samsung K6250. The motion performance and input lag are great. Overall the Vizio M Series 2016 provides much better value.
The LG LH5750 is cheap 1080p TV, with similar picture quality. It has more motion blur, and the picture quality degrades a bit faster when viewed at an angle. It has the advantage in a bright room, where the semi gloss finish works better to deal with reflections and the screen gets brighter to combat glare. There are better TVs out there for the same price.
