In the UN50RU7100FXZA review we can establish that this is a good 4k LED TV that features a decent overall picture quality. With tis TV, you can achieve deep blacks as it has high native contrast ratio and works well in a dim room. The downside of it is that it doesn’t have local dimming functionality which is supposed to improve dark room performance. It also has poor HDR peak brightness and the image degrades when viewed at an angle. However, this TV reviewed has excellent low input lag with good uniformity.


The Samsung UN50RU7100FXZA has a plastic stand which is designed to accommodate the weight of the TV well. It is almost the same width of the TV although it has some wobbling but it isn’t too much. The footprint of the 55” TV stand is 38.3” x 10.4”.

The back of the TV has control buttons and provision for wall mount (VESA 200×200). It is plain and made of quality plastic and the texture is matte having several horizontal ridges which is almost the same as the NU7100. It has the cables serviced through the tracks which are beneath the back.

The borders are plain and have an average thickness of 0.61” (1.5cm). It has a maximum of 2.25” (5.7 cm) thickness which is almost the same as the NU7100 and is roughly uniform. It has a maximum temperature of 114oF (45oC) and an average temperature of 95oF (35oC). Its bottom edge gets quite warm most probably due to the edge LEDs which is not a big alarm.

In terms of the build quality, the RU7100 is decent with the entire casing made of plastic. It doesn’t have loose ends or gaps.

Picture quality

With picture quality reviews we can notice that the RU7100 has a decent picture quality as it has a high native contrast ratio and is capable of delivering deep uniform blacks suitable for watching movies in very dark rooms. However, this TV lacks a local dimming feature that essentially improves dark room performance. Otherwise, the RU7100 TV gets decently bright suitable for watching in average-lit or dim room. On the other side, it doesn’t have a wide colour gamut and doesn’t get bright enough to deliver a good HDR performance.

It has decent reflection handling and good gray uniformity which is good to watch sports. The TV however has narrow viewing angles as the image quickly loses accuracy when viewed from the side. The SDR peak brightness is decent and slightly better than the NU7100 and has very good black uniformity but there is some flash lighting which is not visible under normal viewing conditions.

The UN50RU7100FXZA has decent reflection handling similar to the NU7100 and has excellent colour accuracy after calibration. The remaining inaccuracies are almost impossible to trace them without the aid of a colorimeter. When you change the colour space settings from Auto to Custom reduces the colour gamut drastically and therefore it is recommended to leave it at Auto.


The Samsung RU7100 doesn’t have a pleasing motion handling. It has a fast response time meaning there is a very short blur trail behind fast-moving objects. The TV has very little stutter and motion appears fluid in lower frame rate content like movies. It supports Motion Interpolation up to 60Hz and it has a BFI (Black Frame Insertion) feature that gives the image a crisper look but doesn’t work well.

The responsive time for the RU7100 is very good with most of the transitions very fast giving a very short blur trail behind fast-moving objects. However, you might experience some bit of smearing because of the longer transition between darker shades. This TV doesn’t have Flicker-free and doesn’t support AMD’s Free Sync variable refresh rate compared to the higher-end Q60R model.


The Samsung UN50RU7100FXZA review in terms of inputs features excellent low input lag and supports most common resolutions that include 1440p @ 60Hz which is popular amongst gamers. It is also found to display proper Chroma 4:4:4 in all supported resolutions when it is in the PC mode but doesn’t support DTS or eARC.

It supports most common resolutions and refresh rates and has 3 HDMI, 2 USB, 1 Digital Optical Audio out, 1 shared component In, 1 shared composite in, 1 tuner (cable/Ant) and 1 Ethernet. It also has HDR10, HDR10+ HLG, HDMI 2.0 Full Bandwidth, CEC, HDCP 2.2 and Wi-Fi support. It also has ARC, 5.1 Dolby Digital via ARC and 5.1 Dolby Digital via Optical.

Sound quality

It has a decent sound quality which is almost identical to NU7100 but has a mediocre frequency response. The distortion performance however is decent as the overall amount of harmonic distortion produced is within the decent limits.

Smart features

It has decent smart features having the latest version of Samsung’s Tizen OS and the interface is easy to use with an average smoothness. It has ads, apps and features, a medium sized remote control and the TV controls are located underneath the Samsung logo.


The Samsung Ru7100FXZA is a decent entry-level UHD TV which is a replacement of the NU7100 in Samsung’s line-up and is affordable. It however lacks some of the advanced features found on higher-end models like the Samsung RU8000.
