Our take on the Samsung UN75NU7100 75" 4K UHD Smart LED TV
The Samsung UN75NU7100 is a 75-inch 4K UHD LED smart TV from Samsung's 2018 NU7100 line. It has a flat panel, HDR10 support, the Tizen smart platform with built-in browsing, and a full set of wired inputs including three HDMI ports, two USB ports, Ethernet, coaxial and an ATSC tuner. It suits large living rooms and buyers who want a big-screen 4K set with Samsung's app ecosystem at the entry end of the lineup. Against rivals it trades the wide viewing angles and deeper blacks of pricier sets for a straightforward edge-lit LED picture, and owners generally rate the picture for the size while noting average black levels and modest built-in sound.
- Large 75-inch 4K panel for an immersive picture
- HDR10 support for compatible content
- Tizen smart platform with a wide app selection
- Three HDMI inputs plus two USB ports
- Can be wall mounted
What reviewers say
Owners of the NU7100 series generally praise the sharp 4K picture and the size for the money, and find the Tizen apps easy to use. Common complaints are the black levels in dark scenes and sound that needs a soundbar.
- Picture qualityPraisedOwners say 4K content looks sharp and detailed on the large panel.
- Black levelsCriticisedDark scenes look grey and washed out compared with sets that have local dimming.
- SoundCriticisedBuilt-in speakers are thin, and many owners add a soundbar.
Questions and answers
- Is this TV good for dark rooms?
- Not its strength. The edge-lit panel has no local dimming, so blacks look grey in a dark room. It does better in a bright room or for daytime viewing.
- Does it support HDR?
- Yes, it supports HDR10. It does not support Dolby Vision, so HDR content from services that use Dolby Vision plays in standard HDR10.
- What inputs does it have?
- Three HDMI ports, two USB ports, Ethernet, a coaxial input and an ATSC tuner for over-the-air channels. It also has built-in Wi-Fi for streaming.
- Can it be wall mounted?
- Yes. It is VESA wall-mountable, though a 75-inch set needs a mount rated for its weight and a stud-finding installation.
- Is it good for gaming?
- It handles casual gaming, but it lacks the high refresh rate and low input lag features of dedicated gaming TVs. Serious gamers should look at sets with HDMI 2.1 and 120Hz panels.
- How does it compare with the NU8000?
- The NU8000 is the step-up model with better brightness, local dimming and a faster panel. The NU7100 is the entry 4K set, so expect a simpler picture and fewer features.
