The Samsung RU7300 is an okay 4k TV that delivers decent picture quality on a curved screen. Its VA panel can produce deep blacks, which is great for dark room viewing, and its outstanding low input lag provides a responsive gaming experience. However, it lacks advanced gaming features like FreeSync, and its refresh rate is limited to 60Hz. Furthermore, its response time is poor, which results in a bit more motion blur during fast-moving scenes. Its HDR performance is quite limited, as it can't display a wide color gamut and it doesn't get very bright. It has good color accuracy, though, and Samsung's Tizen OS is a good, user-friendly platform that has tons of apps available.

Our Verdict

6.8 Mixed Usage

The Samsung RU7300 is an okay TV for most uses. Its VA panel can produce deep and uniform blacks, making it a good choice for dark room viewing. It has decent reflection handling and it can get bright enough for a moderately-lit room. It has excellent low input lag for gaming, but it doesn't support any variable refresh rate technologies to reduce screen tearing. Unfortunately, it can only provide an okay HDR experience, as it can't display a wide color gamut and it can't get bright enough to make highlights pop.

Pros
  • Produces deep, uniform blacks.
  • Excellent low input lag.
Cons
  • Disappointing viewing angles.
  • Limited HDR performance.
6.5 Movies

The Samsung RU7300 is an okay TV for watching movies. It produces deep blacks but lacks a local dimming feature to improve dark room performance. Although its poor response time results in more motion blur, it also causes less stutter in 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.

7.2 TV Shows

The Samsung RU7300 is a decent TV for watching TV shows. Its VA panel has poor viewing angles, so it's not the best choice if you like to walk around while watching. It has decent SDR peak brightness and 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. It can upscale lower-resolution content well, and you can safely leave the news running all day long with no risks of permanent burn-in.

6.7 Sports

The Samsung RU7300 is an okay TV for watching sports. Its response time is a bit slow and there's some dirty screen effect in the middle of the screen, which can be distracting. Unfortunately, it isn't bright enough to overcome glare in a bright room, and its poor viewing angles aren't well-suited for watching the big game with a large group of friends. On the upside, it can upscale lower-resolution content like cable sports well, and it has an optional black frame insertion feature that can help reduce motion blur.

7.3 Video Games

The Samsung RU7300 is a decent TV for playing video games. It has outstanding low input lag, but its response time is poor, so fast-moving objects have a bit of blur behind them. The backlight's flicker frequency also causes some duplication of the image, which can be rather distracting. There's no FreeSync support, but it does support most common resolutions, including 1440p, which is great.

6.3 HDR Movies

The Samsung RU7300 is a mediocre TV for watching HDR movies. It can produce deep and uniform blacks thanks to the VA panel's high contrast ratio, however, it lacks a local dimming feature. Unfortunately, it can't get very bright in HDR, and can't display a wide color gamut, so HDR content won't look significantly different from SDR content. Additionally, it can't remove judder from any source.

6.8 HDR Gaming

The Samsung RU7300 is an okay TV for HDR gaming. It has outstanding low input lag and supports most common resolutions, however, it has a poor response time and there are noticeable duplications in some motion due to the PWM flicker of the backlight. Its HDR performance is severely limited by the lack of a wide color gamut and it can't get bright enough to make a dramatic difference from SDR.

7.2 PC Monitor

The Samsung RU7300 is a decent TV for use as a PC monitor. It can display full 4:4:4 chroma with no issues and it supports most common resolutions. Input lag is low, but its slow response time means there's more noticeable blur trail behind fast-moving objects. Its VA panel has poor viewing angles, so the images look washed out at the sides if you sit too close. Thankfully, you won't have to worry about permanent burn-in, as most VA panels are immune.

Market Context

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's very similar to the Samsung RU7100 and replaces 2018's Samsung NU7300. Except for the curved screen, it's mainly comparable to other budget TVs, like the LG UM7300 and the Sony X800G.

Design
8.5
Design
Style
Curved Yes

The RU7300 has an excellent design, nearly identical to the NU7300, but with a curved screen. The bezels are thin on all sides and the wide-set stand supports the TV well. Due to the curvature of the screen, the TV is quite a bit thicker than non-curved models, so it sticks out a bit more when wall-mounted.

Design
Stand

The stand supports the TV well but does wobble a bit if nudged. The feet are placed far apart, so it does require a larger table if it isn't wall-mounted. This leaves enough room to place a moderately-sized soundbar in front of the TV.

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

Design
Back
Wall Mount VESA 200x200

The back is plain and it has a horizontal texture etched into it. There are grooves to guide the cables towards the feet and you can attach them using the provided clips, serving as basic cable management.

The TV can also be VESA mounted, but requires special spacers (included in the box) due to the curvature of the back.

Design
Borders
Borders 0.59" (1.5 cm)

The borders are a bit thicker than premium Samsung TVs, but still thin enough that they aren't very distracting.

Design
Thickness
Max Thickness 4.02" (10.2 cm)

Due to the curvature of the screen, the TV is quite thick and sticks out a bit more when VESA-mounted.

Build Quality

Decent overall build quality. Although it isn't made from premium materials, there aren't any obvious issues with the construction.

There's 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 isn't necessarily indicative of any quality control issues with the RU7300.

Mediocre peak brightness. The brightness is fairly consistent when displaying different content, with only the 2% window being noticeably dimmer due to the TV's CE dimming (frame dimming). It's bright enough for use in dark to moderately-lit rooms, but it won't be able to overcome glare in very bright rooms.

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.

Disappointing HDR Peak Brightness. Small highlights in dark scenes are dimmed by the TV's frame dimming (CE dimming) feature, which unfortunately can't be disabled.

We measured HDR Peak Brightness in the 'Movie' Picture Mode, with our pre-calibration settings.

The TV has outstanding black uniformity, despite the lack of a local dimming feature. Some clouding is noticeable, especially in the top right corner of our unit, but this may vary between individual units.

There's a stuck pixel noticeable in the black uniformity image. This wasn't very noticeable in normal content, and we don't expect it to have any impact on our test results.

Before calibration, color accuracy is good. There are inaccuracies with several colors and the color temperature is much warmer than our 6500K target, resulting in a slight reddish tint. White balance is off as well, and gamma doesn't follow the target at all, with most scenes looking brighter than they should.

After calibration, color accuracy is outstanding. White balance and gamma are nearly perfect, and the color temperature is much closer to our 6500K target. However, there are still some noticeable inaccuracies with reds and blues.

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.'

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.

PWM Dimming Frequency
240 Hz

This TV uses PWM (Pulse-Width Modulation) 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.

This TV 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
Motion Interpolation

Yes
Motion Interpolation (60 fps)
No

The TV has an optional motion interpolation that can only interpolate lower frame rate content up to 60Hz. The TV does a good job overall 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 doesn't 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.
