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.
:
VA
Resolution : 4k

The Samsung RU7100 is a good 4k LED TV that has decent overall picture quality. It can deliver deep blacks, thanks to the high native contrast ratio, and it is good for a dim room. However, it lacks a local dimming feature to further improve dark room performance. It has good gray uniformity and great color accuracy out of the box. It doesn't have a wide color gamut and can't get very bright, especially in HDR. Motion handling is mediocre, but the input lag is remarkably low, which makes the TV very responsive; something that will please gamers. Unfortunately, it does not support any of the advanced gaming features found on higher-end Samsung models, and the image loses accuracy when viewed from the side.

Market Context

What it is: This model's position in the TV market; how it compares to other TVs.

The Samsung RU7100 is a 2019 entry-level UHD TV. It is the replacement of the NU7100 in Samsung's lineup, and it is meant as a more budget model that lacks some of the more advanced features found on the higher-end UHDs like the Samsung RU8000. It is comparable to most other budget LED TVs, like the LG UK7700 or the Vizio E Series 2018.

Design

Score components: Subjectively assigned
Samsung RU7100 Design Picture
Curved : No

The design of the Samsung RU7100 is excellent, similar to last year's Samsung NU7100. The stand supports the TV well and allows only minimal wobble. It is, however, nearly as wide as the TV, so you need a large table to place it on. The back of the TV is made of plastic with the same textured finish found on last year's Samsung TVs. Cable management is serviced through guide tracks on the back of the TV and with the help of a couple of clips that attach to the legs. The build quality is decent, and you should have no issues with it.

Stand
Samsung RU7100 Stand Picture

The stand is plastic but supports the TV well. It is almost as wide as the TV, and the legs cannot be reversed. There is some wobble, but not too much.

Footprint of the 55" TV stand: 38.3" x 10.4"

Back

Wall Mount : VESA 200x200

The back of the TV is plain. It is made of good quality plastic and the texture is matte with a lot of fine horizontal ridges, just like last year's NU7100.

Cable management is serviced through tracks found near the bottom of the back and the special clips that attach to the legs, as shown here.

Borders

The bottom edge of the Samsung RU7100 gets quite warm. This is likely due to the edge LEDs, but shouldn't cause any issues.

6.5 Build Quality
Samsung RU7100 Build quality picture

The RU7100 has decent overall build quality. The external casing is almost entirely made of plastic. There are no gaps or loose ends other than some flex in the seam where the back joins the borders; this should not be an issue.

7.4

Picture Quality

The picture quality of the RU7100 is decent. It has a high native contrast ratio and can deliver deep uniform blacks, but it lacks a local dimming feature to further improve dark room performance. It can get decently bright, and it is more suitable for an average-lit or dim room. It does not have a wide color gamut and cannot get bright enough to deliver a good HDR performance. The Samsung UN55RU7100 has decent reflection handling and good gray uniformity that will please most sports fans. Unfortunately, it has narrow viewing angles, just like most VA panel TVs, and the image quickly loses accuracy when viewed from the side.

The SDR peak brightness of the RU7100 is decent, just slightly better than last year's NU7100. The UN55RU7100 is more suitable for average-lit or dim rooms, as it cannot get bright enough to overcome glare.

We measured the peak brightness after calibration, using the 'Movie' picture mode, 'Warm 2' color temperature, '2,2' gamma, and we set Auto Motion Plus Settings to 'Off.' Different picture modes and color temperatures may be brighter.

The setting that controls the brightness of the backlight is called Backlight.

The HDR peak brightness is disappointing. The RU7100 can't get bright enough to deliver a vivid HDR image. Small highlights in dark scenes are dimmed by the TV's algorithms, as shown by our 2% window test. This is known as CE dimming.

Our measurements were taken in the 'Movie' picture mode, with no calibration settings and Auto Motion Plus settings set to 'Off.' Some settings may produce a brighter image.

The RU7100 has good gray uniformity. The 50% gray image is a little darker at the sides and especially at the corners. However, the center of the screen is more uniform, so the minor dirty screen effect isn't very noticeable. This is great news if you enjoy watching sports.

In the 5% gray image, the uniformity is good and you can't easily spot any uniformity issues.

The viewing angle is disappointing, just like with most VA panel TVs. The image loses accuracy at fairly small angles off-center. As you increase your viewing angle, you will first notice the blacks intensifying, then a shift in grayscale shades followed by a shift in the colors, and finally, the brightness will begin to fade.

The out of the box color accuracy of the RU7100 is great. The Picture Mode that gave us the best results is the 'Movie' picture mode. The minor color inaccuracies are hard to spot unless you are an enthusiast. With Color tone set to 'Warm 2,' the color temperature is slightly colder than the 6500K target. The gamma does not follow our target and some scenes are brighter than others.

9.3 Post Calibration

The RU7100 has excellent color accuracy after calibration. Any remaining inaccuracies are almost impossible to spot without the aid of a colorimeter. The color temperature is almost spot on the 6500K target, and the gamma follows the target curve more closely, but not perfectly.

Changing Color Space settings from 'Auto' to 'Custom' reduced the color gamut drastically, so we had to make big changes in the color calibration. We recommend that users leave it at 'Auto' to avoid this.

Samsung RU7100 EOTF

The RU7100 has a decent color gamut. It is not wide enough for great HDR performance, but it is still wider than most SDR TVs, and an improvement over last year's NU7100.

The 'Movie' EOTF cannot follow the input stimulus closely and produces less bright images.If you find HDR content too dark, you can try setting Contrast Enhancer to 'High' and Brightness to '5.' With all of these enabled, the image gets brighter, as shown here.

In 'Game' mode, the EOTF cannot follow the target curve closely and starts to roll-off relatively early, very similar to the 'Movie' mode EOTF.

Motion

The motion handling of the Samsung RU7100 is mediocre. It has a fast response time, so there is only a very short blur trail behind fast-moving objects. The backlight uses PWM to dim and the flicker frequency is 240Hz but it drops to 120Hz in some modes, and this might bother some people. This TV has very little stutter, and motion appears fluid in lower frame rate content like movies. It supports motion interpolation up to 60Hz and has a Black Frame Insertion feature to make the image crisper, but it does not work very well.

Very good response time for the RU7100. Most transitions are fast, so there is only a very short blur trail behind fast-moving objects. In dark scenes, however, some smearing may be present due to the longer transition between darker shades, such as from 0% to 20%.

Good value: 0 Hz or very high frequencies (> 300 Hz). Frequencies that are multiples of 60Hz are better.
:
240 Hz

The RU7100 uses PWM to dim the backlight. Only when the backlight is set at max is there no flicker. The flicker frequency is 240Hz and was measured in 'Movie' mode with Auto Motion Plus disabled. Unfortunately, some TV settings have 120Hz flicker. Simply setting Auto Motion Plus to 'Custom' changes the flicker to 120Hz. The 'Game' and 'Standard' picture modes have 120Hz flicker all the time, as shown here.

This changing flicker frequency has also been observed in other Samsung TVs like the Q60R.

9.1 Black Frame Insertion (BFI)
What it is: How effective the TV's flickering capabilities are in making motion look clearer, when flicker is desired.
When it matters: When flicker is desired by the user. Flicker is especially useful to make motion look clearer when viewing 60 fps content (sports, video games) and when using motion interpolation.

The RU7100 gives you the option to introduce flicker to make the image crisper. In 'Movie' mode, setting Auto Motion Plus to 'Custom' changes the flicker of the backlight to 120Hz, as explained in the Flicker-Free box. If you don't want Motion Interpolation, set Judder Reduction to '0.'

Activating LED Clear Motion changes the flicker to 60Hz. Unfortunately, motion with 60Hz BFI doesn't look good, as you can see in the photo above. This happens because the pulse timing isn't very good. The backlight pulse catches the TV in mid-transition, resulting in the double-image seen in the photo.

In 'Game' mode, the backlight always flickers at 120Hz, and unfortunately can't be made to flicker at 60Hz.

7.0 Motion Interpolation
What it is: Also known as 'Soap Opera Effect'. It is an optional feature that increases the frame rate of the video, smoothing movement.

The Samsung RU7100 can interpolate lower frame rate content up to 60Hz. To enable motion interpolation, set Auto Motion Plus to 'Custom' and adjust the Judder Reduction slider. Leave LED Clear Motion to off unless you want Black Frame Insertion.

Note that, like many Samsung TVs, simply setting Auto Motion Plus to 'Custom' changes the backlight flicker from 240Hz to 120Hz, as explained in the Flicker-Free box.

Low-end Samsung TVs like the RU7100 do not have a Game Motion Plus option to add motion interpolation in 'Game' mode.

The RU7100 supports most common resolutions and refresh rates, including 1440p @ 60Hz, just like the Q60R. Full bandwidth signals, such as 4k @ 60Hz @ 4:4:4, require Input Signal Plus to be enabled for the input in use. Input Signal Plus is the new name for what was previously known as HDMI UHD Color.

Chroma 4:4:4 is properly shown in all resolutions provided the TV is in 'PC' mode.

Like the Q60R and 2018 Samsung TVs, the RU7100 does not support DTS, nor does it support eARC. Like the Q60R, there is a Dolby Atmos Input setting, so it likely does support lossy Atmos passthrough via Dolby Digital Plus sources, such as the native Netflix app.

6.5

Sound Quality

What it is: How well and accurately the audio is reproduced.
When it matters: When a good and accurate sound reproduction is needed.
Score components:

The sound on the Samsung RU7100 is decent, almost identical to NU7100. It can get decently loud but may not be loud enough for large or noisy environments. It doesn't have deep bass and won't produce any thump or rumble, but it will deliver clear and intelligible dialog. For a better sound, dedicated speakers or soundbars are recommended.

When it matters: When an accurate and free-of-pumping performance is required at higher volumes
Good value: < 3dB
Noticeable difference: 0.5
:
4.48 dB

The frequency response is mediocre. LFE (low-frequency extension) is at 80Hz, which is decent. This means the RU7100 has a decent amount of punch to its bass but can't produce any thump or rumble. The response above the LFE is relatively flat and well-balanced, and this results in clear and intelligible dialogs. The RU7100 doesn't have a room correction system, and we weren't able to remove the modes of our test room around 200Hz. The RU7100 can get reasonably loud, but not loud enough for large and noisy environments.

7.0 Distortion
What it is: Deformation of an output signal compared to its input, usually clipping, harmonic distortion, or inter-modulation distortion caused by non-linear behavior of the sound system.
When it matters: When a clean, pure and transparent reproduction is desired.

Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The RU7100 is a good entry-level UHD TV, but there are better TVs for the same price.

Samsung NU7100
40" 43" 50" 55" 58" 65" 75"

The Samsung NU7100 and the Samsung RU7100 both have very similar performance. The RU7100 has a slightly faster response time which is great if you watch sports, and a much lower input lag which is great for those who play video games. The NU7100, on the other hand, can deliver more uniform blacks.

Samsung Q60/Q60R QLED
43" 49" 55" 65" 75" 82"

The Samsung Q60R is better than the Samsung RU7100. The Q60R has a faster response time which is great for fast-moving content like sports, and it can also remove 24p judder from any source. The Samsung RU7100 has a little lower input lag, which is great for video games, but the Q60R supports FreeSync.

Vizio E Series 2018
43" 50" 55" 65" 70" 75"

The Vizio E Series 2018 is a bit better than the Samsung RU7100. The Vizio has a local dimming feature that further improves dark room performance and can remove 24p judder from some sources. The Vizio has a faster response time and better reflection handling. The Samsung RU7100 has a lower input lag, great for gaming, and a motion interpolation feature.

LG UK7700
55" 65"

The LG UK7700 and the Samsung RU7100 are different types of TVs, so if you have a dark room and you sit straight in front of the TV, the RU7100 is a better choice as it has deeper and more uniform blacks. If you have a room with a wide seating arrangement and many lights, then the LG UK7700 is a better choice as the image remains accurate when viewed from the side and the TV has better reflection handling.

Conclusion
SEE PRICE
Amazon.com

7.5Mixed Usage
What it is: General purpose. The TV will be used for a variety of content and usages. Movies at night, TV shows during the day, video games from time to time, etc.
Score components:
This is a good TV for mixed usage. It is more suitable for darker rooms as it can't get very bright to overcome glare. It has a low input lag that makes it very responsive, but unfortunately, you have to sit straight in front to enjoy the most accurate image due to the poor viewing angles.
6.6Movies
What it is: Movies in the dark. The TV will be used for watching movies in a controlled environment, directly in front, in a home theater way. Mostly only high quality content, like Blu-rays, UHD Blu-rays, streaming and a little bit of HDR.
Score components:
The RU7100 is a decent TV for watching movies in a dark room. It has an excellent native contrast ratio and can deliver deep blacks, but it lacks a local dimming feature to further enhance dark room performance. Unfortunately, it can not remove 24p judder from any source.
7.5TV Shows
What it is: TV Shows in a bright living room. The TV will be used in to watch TV shows, in a bright room during the day, from multiple viewing positions at different angles. The content watched has an average quality: cable, streaming, SD channels, etc.
Score components:
This is a good TV for watching TV shows. It has decent reflection handling but can't get very bright, so it is more suitable for a room with less light. The gray uniformity is good, but the viewing angles are poor, and you are better off sitting straight in front.
7.3Sports
What it is: Sports in a living room. The TV will be used to watch sports during the day, like football or hockey. Usually watched with a group, so from multiple viewing position.
This is a decent TV for watching sports. It has a fast response time, and fast-moving objects only have a small blur trail. The gray uniformity is good, and you should not experience any dirty screen effect when watching your favorite game. Unfortunately, the RU7100 is not a good choice for a large room with a wide seating arrangement due to its poor viewing angles.
8.5Video Games
What it is: Video games. The TV will be used to play video games, directly in front, in a controlled light environment. Usually fast games, like online FPS, where motion blur and input lag is important.
The RU7100 is an excellent TV for playing video games. It has a remarkably low input lag and a fast response time, so it is very responsive to your actions. Unfortunately, it doesn't have FreeSync or any other game enhancing features like the ones found on higher-end models like the Samsung Q60R.
6.7HDR Movies
What it is: HDR Movies and TV shows. The TV will be used to watch 4k UHD HDR content, with a wide color gamut and a high peak brightness. Either via UHD Blu-rays or HDR streaming.
Score components:
This is a decent TV for watching HDR movies. It can deliver deep blacks in a dark room, but it lacks a local dimming feature to further improve dark room performance. The TV doesn't have a wide color gamut and can't get very bright in HDR, so it cannot display HDR content as its creator intended.
7.9HDR Gaming
What it is: HDR Gaming. The TV will be used to play HDR video games using consoles that support it or on current generation gaming PCs. Xbox One S, PS4 Pro, GTX 10 series and AMD RX series graphics cards.
This is a good TV for playing HDR games. This is mainly due to the extremely low input lag and the fast response time, and not so much due to its HDR performance. The RU7100 is very responsive, but HDR content does not display as it should due to the lack of a wide color gamut and the low brightness levels in HDR.
8.2PC Monitor
What it is: PC Monitor. The TV will be used as a PC monitor, from 2-3 feet away, either for productivity purposes or gaming. Sharp text is important, as well as a high resolution.
Score components:
The RU7100 is a great TV for use as a PC monitor. It has a remarkably low input lag, and it is very responsive. Unfortunately, the viewing angles are poor, and you will lose image accuracy at the sides, especially if you sit up close. It can display proper chroma 4:4:4 in all supported resolutions, and this is great.
