Samsung RU7300
TV REVIEW
Sub-Type
:
VA
What it is:
Type of display technology used by the TV.
When it matters:
Different technologies have different performance and are suited to different uses
Good value:
IPS maintains good color accuracy at an angle, but has a poor contrast ratio from in front. VA has great picture quality in front, but loses saturation at an angle. OLED maintains good color accuracy at an angle without any of the other issues seen with IPS and VA, as they keep good brightness and contrast at an angle.
The Samsung RU7300 is a decent curved 4k TV that delivers decent picture quality with deep, uniform blacks and good gradient performance. It has outstanding low input lag, great for a responsive gaming experience, but lacks the more advanced gaming features found on premium Samsung TVs, like FreeSync. It has mediocre motion handling. Unfortunately, the image degrades when viewed at an angle, so it isn't as well-suited for those with a wide viewing area. It has limited HDR performance, as it can't get very bright, and can't display a wide color gamut.

Market Context
What it is:
This model's position in the TV market; how it compares to other TVs.
The RU7300 is a budget 4k TV, and is the only curved TV that has been announced for Samsung's 2019 lineup so far. It is very similar to the Samsung RU7100, and replaces last year's Samsung NU7300. Except for the curved screen, it is mainly comparable to other budget TVs, like the LG UM7300 and the Sony X800G.
Design
Score components:
Subjectively assigned
Score distribution:
The RU7300 has a decent design, nearly identical to last year's NU7300, and very similar to the RU7100, but with a curved screen. It has decent build quality and a simple stand that supports the TV well but wobbles a bit. The back of the TV is made of plastic and has only very basic cable management. Due to the curvature of the screen, the TV is quite a bit thicker than non-curved models, so it stands out a bit more if wall-mounted.
The back is very plain and is identical to most 2019 Samsung TVs. Like the RU7100, there isn't much to help you with cable management, but there are clips that attach to the legs, and grooves just above the stand that can be used to run cables along the back of the TV.
The RU7300 can also be VESA mounted, but requires special spacers (included in the box) due to the curvature of the back.
The RU7300 is quite a bit thicker than the RU7100, due to the curvature of the screen, so it stands out a bit more when VESA mounted.
Temperature
What it is:
It is the average and maximum operating temperatures we measured on the TV. If there is an external device, like a One Connect box in some Samsungs, we measure the temperature of that as well.
When it matters:
If the temperature of your TV is much higher, check that nothing is blocking the vents.
6.5
Build Quality
What it is:
It represents our perception of the quality of the construction of the TV, of the materials used, and how they all blend.
When it matters:
Poor build quality might lessen the expected lifetime of the TV, or make it more prone to faults due to mishandling.
Score components:
Subjectively assigned
Score distribution:
The TV has decent overall build quality, very similar to the RU7100 and the 2018 NU7100 and NU7300. Although it doesn't seem to be made from premium materials, there didn't appear to be any issues with the build quality.
There is a stuck pixel in the bottom left side of the screen; it can be seen in our Black Uniformity image. This can occur with any TV and is not necessarily indicative of any quality control issues with the RU7300.

Score distribution:
The Samsung RU7300 delivers decent overall picture quality, very similar to the NU7300 and RU7100. It has an excellent native contrast ratio that delivers deep blacks and excellent black uniformity, but it does not have a local dimming feature. It has decent peak brightness in SDR, but can't get bright enough in HDR to show off small highlights in some scenes. Unfortunately, like most VA panels, the image degrades when viewed at an angle, and it can't display a wide color gamut.

Good value:
<0.07
Noticeable difference:
0.01
Score distribution:
Decent peak brightness, with almost no variation in brightness with different window sizes, which is great. Very small, bright highlights are dimmed by the TV's frame dimming (also known as CE dimming) feature. Unfortunately, this cannot be disabled. The peak brightness is very similar to the RU7100, but not as good as the higher-end Samsung TVs, like the Q60R.
SDR Peak Brightness was measured after calibration, using the 'movie' Picture Mode, with the Color Tone set to 'Warm 2,' and Gamma set to '2.2.' Different settings may be brighter.

The RU7300 has good accuracy with our pre-calibration settings. Colors have good accuracy, and most people won't notice any issues. White Balance dE is a bit higher, and gamma doesn't follow our target of 2.2 very well, so most scenes are over-brightened a bit.

What it is:
The color temperature is a measure of the color of light. A colder color temperature (7000K) will look bluer and a warmer color temperature (4000K) will look yellower/redder. 6500K is the standard color temperature use in the TV and film industry as program, film, and photography directors usually work on monitors calibrated on the 6500k color temperature and do their color correction base on what they see on those monitors.

When it matters:
When calibrating the TV.
Outstanding accuracy after calibration. The white balance is extremely accurate, and gamma follows our target of 2.2 perfectly. Overall, colors are accurate, but saturated reds and blues still have inaccuracies that might be noticeable. The color temperature is almost exactly on our calibration target of 6500K.
Changing the Color Space Settings from 'Auto' to 'Custom' caused a noticeable reduction in the color gamut, same as the RU7100. We recommend leaving this set to 'Auto.'

Score distribution:
The TV has a decent color gamut, but falls short of being able to display a wide color gamut. It can't display the wide range of greens and reds needed for HDR content to really stand out. Unfortunately, in both 'Movie' and 'Game' mode, the RU7300 does not follow the PQ curve very well, and most scenes appear dimmer than the content creator intended.
If you find HDR too dim, see our recommended settings here. With these settings, the RU7300 is noticeably brighter in HDR, as shown in this EOTF.

The Samsung RU7300 has mediocre motion handling. It has a decent response time, but there is a noticeable blur trail in some scenes, and there are noticeable duplications in motion due to the backlight flicker (PWM). It has an optional motion interpolation feature, but can only interpolate up to 60Hz. The TV has a 60Hz panel and does not support any of the advanced gaming motion features, like FreeSync, found on premium Samsung TVs like the Q90R and NU8000.

Good value:
0 Hz or very high frequencies (> 300 Hz). Frequencies that are multiples of 60Hz are better.
Score distribution:
The RU7300 uses PWM to dim the backlight, except when at 100%. The backlight flickers at 240Hz in 'Movie' mode, which causes some duplications in motion, as seen in the response time motion photo.
Like many other Samsung TVs we've tested, the flicker frequency decreases to 120Hz in other modes, including if Auto Motion Plus is set to 'Custom,' and in 'PC' mode. This fairly low flicker frequency may bother some people.

The Samsung UN55RU7300 has an optional Black Frame Insertion(BFI) feature. When enabled, the backlight always flickers at 60Hz, but like the RU7100, the pulse timing isn't very good, causing some double images like the photo above.
In 'Game' mode, BFI isn't available, and the backlight always flickers at 120Hz.

Motion Interpolation (60 fps)
:
No
What it is:
Whether the TV can take a 60 fps input and heighten the frame rate to at least 100 fps.
When it matters:
60 fps videos. Includes some video games, some sports channels.
The TV has an optional motion interpolation feature. As it is a 60Hz panel, it can only interpolate up to 60Hz. The TV does a good job interpolating up to 60Hz, and there are very few artifacts. Like most TVs, when it can't keep up with demanding scenes, it will stop interpolating, which can cause a sudden change in frame rate, which may be noticeable. Unlike the higher end Samsung TVs, the RU7300 does not support low latency motion interpolation in 'Game' mode.
Like other Samsung TVs we've tested, the flicker frequency on the RU7300 decreases to 120Hz when Auto Motion Plus is enabled. This fairly low flicker frequency may bother some people.
See here to learn how to enable motion interpolation on the RU7300.

The RU7300 is a good entry-level curved UHD TV, but there are better TVs for less. See our recommendations for the best TVs, the best HDR gaming TVs, and the best smart TVs.
Samsung RU7100
43" 50" 55" 58" 65" 75"
The Samsung RU7300 and Samsung RU7100 are extremely similar, but the RU7300 has a curved screen. Other than that, they are essentially the same TV.
Samsung NU7300
55" 65"
The Samsung RU7300 is the replacement for the Samsung NU7300, and there are no significant differences between the two. The RU7300 now supports 1440p, and it has a dedicated component input at the back, instead of the adapter used by the NU7300. The RU7300 also adds support for 5 GHz wifi.
TCL 6 Series/R617 2018
55" 65" 75"
The TCL 6 Series/R617 2018 is much better than the Samsung RU7300. The R617 has a full array local dimming feature and is significantly brighter than the RU7300. The R617 also has a much faster response time and can remove judder from all sources. The RU7300 has a curved screen, which can make some reflections more noticeable.
TCL 5 Series/S517 2018
43" 49" 55" 65"
The TCL 5 Series/S517 2018 and the Samsung RU7300 are very similar overall. The RU7300 has much better black uniformity and an optional black frame insertion feature. The TCL S517 has a slightly faster response time and can remove judder from all sources.
Vizio E Series 2018
43" 50" 55" 65" 70" 75"
The Vizio E Series 2018 is a bit better than the Samsung RU7300. The E Series has a local dimming feature, although this doesn't add much, and it has a much faster response time. The E Series can also remove judder from most sources, but lacks a motion interpolation feature. The RU7300 has a curved screen, a motion interpolation feature, and lower input lag.

The Samsung RU7300 is a good TV for most uses. It produces deep, uniform blacks, but lacks a local dimming feature. In SDR, it gets bright enough for most moderately-lit rooms and has decent reflection handling. It has excellent low input lag but doesn't support any advanced gaming features, like FreeSync. Unfortunately, it can't get bright enough for HDR to stand out the way it should, and can't display a wide color gamut.
The Samsung RU7300 is a decent TV for watching movies. It produces deep blacks but lacks a local dimming feature to improve dark room performance. It has a decent response time but is a bit slower than higher-end TVs, so there is less stutter with 24p movies. Unfortunately, it can't remove judder from any source, but can interpolate movies up to 60Hz, if you enjoy the soap opera effect.
Good TV for watching TV shows overall, but not as good if you like to walk around with the TV on, due to the disappointing viewing angles. It has a great app selection, covering the most popular streaming services. It has decent SDR peak brightness, and decent reflection handling, so you shouldn't have any issues in a moderately lit room, but the curved screen causes some reflections to smear across the screen, which may be distracting in some cases.
Decent TV for watching sports. It has decent peak brightness in SDR, and decent reflection handling, so there shouldn't be any issues watching the game during the day, as long as there aren't too many windows. Unfortunately, it might not be bright enough to overcome glare in a really bright room, and it has poor viewing angles, so it isn't as well-suited for watching the big game with a large group of friends.
The Samsung RU7300 is an excellent TV for playing games. It has outstanding low input lag, but lacks any variable refresh rate technologies, like FreeSync. Fast-moving objects have a bit of blur behind them, though, and there are noticeable duplications due to the relatively low flicker frequency of the backlight. It supports most common resolutions, including 1440p, which is great.
This is a decent TV for watching HDR movies. It produces deep, uniform blacks, but lacks a local dimming feature. Unfortunately, it can't get very bright in HDR, and can't display a wide color gamut, so the advantages of HDR won't be as obvious. It also can't remove judder from any source.
The Samsung RU7300 is a very good TV for HDR gaming, mainly due to its excellent gaming performance. It has outstanding low input lag and supports most common resolutions. It has a decent response time, but there are noticeable duplications in some motion due to the PWM flicker of the backlight.
Good TV for use as a PC monitor. It can display full 4:4:4 chroma with no issues, as long as 'PC' mode is used, and supports most common resolutions. It also has low input lag and a decent response time, but there is a more noticeable blur trail behind fast-moving objects, which may be distracting.
