Our take on the Samsung UN40NU7100 by Crutchfield's Steve Kindig
Ready to upgrade from HD?
If your old TV is looking tired, now's a good time to make the move to 4K. Samsung's UN40NU7100 offers impressive picture quality and smart TV conveniences for a sub-$400 TV. Its super-crisp 4K picture has four times the detail of HDTVs.
Although this model is compatible with HDR (High Dynamic Range) content, it doesn't have the extended color range to make HDR colors pop. And its LED backlight lacks local dimming, so it can't reproduce the picture contrast extremes of HDR material. Still, this basic model looks fine with standard (non-HDR) TV content.
A better looking picture with everything you watch
When you unbox the UN40NU7100 you'll want to start watching right away. The TV's built-in set of streaming apps makes it easy. If you're an Amazon Prime subscriber, you can start watching 4K shows and movies right away — for free! Another streaming service with loads of 4K content is Netflix®.
But you definitely don't need native 4K content to enjoy the UN40NU7100's picture. Samsung's UHD Engine automatically upconverts any signal to match the screen's 4K resolution. All your current video sources will look better than ever.
Speedy web apps and streaming, no waiting
The UN40NU7100's speedy Quad-Core processor lets you browse the web without having to interrupt what you're watching. Whether your connection is wired or wireless, you can switch between apps, stream content, and multi-task much faster than with previous smart TVs.

Features and Specs
4K UHD Engine w/ Upscaling: The Samsung UHD TV has a display resolution of 3,840 x 2,160 (4K) and will display all video at that resolution, regardless of input signal, thanks to UHD upscaling. 4K delivers 4x higher resolution than current 1080p high-definition TVs, so you'll see more on TV than ever before with over 8 million individual pixels (3,840 x 2,160) compared to about 2 million (1,920 x 1,080) on your 1080p HDTV. UHD Upscaling delivers the complete Ultra-HD picture experience with a proprietary process including signal analysis, noise reduction, UHD upscaling, and detail enhancement to seamlessly upconvert SD, HD, or full-HD content to Ultra-HD-level picture quality.
Note: This TV complies with the CTA 4K Ultra High-Definition Connected definition requirements. The trade organization known as the Consumer Technology Association (CTA) is considered an industry authority on engineering standards for consumer electronics in the United States. Visit www.cta.tech for more information.
HDR (High Dynamic Range Video): The Samsung UHD TV features the ability to provide a premium High Dynamic Range (HDR) experience, with a higher level of contrast between light and dark images. HDR delivers a much higher level of contrast between light and dark to produce an image that is more realistic and closer to what the content creator imagined. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth. In addition to supporting the standard HDR10 format, the Samsung UHD TV also supports HDR10+ and HLG; as well as HDR+.
- HDR+: One of the biggest benefits of HDR+ is its ability to upgrade Standard Dynamic Range (SDR) content to HDR-like picture quality, allowing viewers to enjoy all of their favorite content in the highest picture quality possible. With HDR native content, HDR+ also uncovers previously hidden images from darker content scenes, supplementing the level of brightness to express objects hidden in darker shadows. For brighter content scenes, HDR+ increases the level of contrast ratio to differentiate objects from the background, while still depicting more image details on the screen for an overall better picture.
- HDR10+: Samsung Electronics and Amazon Prime Video announced the entire Prime Video HDR library is now available in HDR10+, a new open standard that leverages dynamic metadata to produce enhanced contrast and colors on an expanded range of televisions. Prime Video is the first streaming service provider to deliver HDR10+ content to its users. The HDR10+ technology on Prime Video incorporates dynamic metadata that allows the Samsung UHD TV to adjust brightness levels on a scene-by-scene or even frame-by-frame basis. By applying individualized tone mapping to each scene, HDR10+ delivers an incredible viewing experience. The picture quality offers an enhanced visual experience with more detailed expressions, brighter shadow areas and more accurate color renderings that stay true to the creator's original intent.
- HLG: HLG (Hybrid-Log Gamma) is primarily designed for live video feed and over-the-air broadcasts. It uses no pre-encoded metadata and is backwards compatible with SDR. HLG's native compatibility allows much of today's existing SDR infrastructure to be re-used for HDR in the future.
Increased Color & Contrast: The UHD TV utilizes proprietary Samsung backlight dimming, color, and contrast technologies to product an image with vast color, greater contrast, and more depth.
- PurColor: PurColor allows the TV to express most shades of color as nature intended for optimal picture performance. Most TV's focus on the adjustment points of primary colors Red, Green and Blue. PurColor focuses on primary and secondary colors Magenta, Cyan and Yellow.
- UHD Dimming: UHD Dimming precisely scans an incredible amount of zones across the entire image and adjusts brightness to deliver deeper darks and brighter whites. It virtually eliminates the "halo" effect and image distortion, so you'll enjoy a crystal clear picture.
- Contrast Enhancer: Flat images come to life with Samsung's Contrast Enhancer. The UHD TV intelligently applies varying levels of contrast enhancement to different areas and objects on the screen creating a dramatic 3D-like effect. As a result the TV can provide a realistic viewing experience with depth.
MR 120 + Auto Motion Plus: The Samsung UHD TV combines its 60Hz native panel refresh rate with Samsung's proprietary MR 120 & Auto Motion Plus image processing technology, which is faster and more responsive than conventional image processors, as it interpolates intermediate frames to smooth out the image. MR 120 & Auto Motion Plus helps to remove blur and judder from scenes with large amounts of rapid movement to provide a clearer picture. MR 120 & Auto Motion Plus reduces blur so that action movies, sports and video games have enhanced clarity. Advanced panel and unique backlight technology combine with proprietary algorithms to reduce the response time and yield a more accurate image reproduction with faster onscreen motion.
HDMI 2.0b Inputs: The Samsung UHD TV is equipped with three HDMI 2.0b inputs to connect to your Blu-ray player, Satellite/Cable receiver, Game Console, and/or AV receiver.

- HDCP 2.2 Compliant: HDCP 2.2 compliance makes the TV fully compatible with the latest copyright protection standard for 4K video transmission from Ultra-HD Blu-ray players and 4K Satellite//Cable providers.
- Color Subsampling: With 4:4:4 color subsampling, luminance (brightness) and chroma (color) are sampled at the same rate; resulting in an RGB color palette as big as the video sampling rate for a video image with more total colors, plus greater color accuracy and detail. 4:2:2 (50/60p) and 4:2:0 (50/60p) are also supported by all HDMI inputs.
Notes: This TV does not contain analog composite or component video inputs.

This is a smaller 4K TV, ideal for the room it will be in. Great reviews here on Crutchfield and elsewhere. [ Doug Sep 02, 2018 ]
Was just the right size, with the features I wanted [ John Sep 01, 2018 ]
Previous TV lost sound. Couldn't restore it. Had prior good experiences with Crutchfield. Called Crutchfield. "Travis" was very helpful. Explained things. Opened an order, but didn't push for me to buy right then and there. Had some time to think and to continue my attempts to restore previous TV. When I couldn't, I went with Travis' recommendation. Bought it today. [ WILLIAM Sep 01, 2018 ]

Swapping out an existing 40" TV which will be wall-mounted elsewhere, this TV will fit the cabinet, good price point and I don't need/want the added bells and whistles. [ DIY Dick May 22, 2018 ]

This TV does have screw holes on the back to work with mounts. Those holes meet VESA 200 mounting standard. Just make sure the TV mount you get is VESA 200 compatible and able to support the weight of the TV and you will be all set. Feel free to call an advisor on 1-800-324-9695 for a personal recommendation on a mount for it. My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=101 [ Paul Aug 08, 2018 ] Staff
The only way I know to connect this TV to an analog receiver is to use the Bluetooth transmission that it can do. You can get a Bluetooth audio receiver to use with the TV's Bluetooth and get the audio into an analog receiver. You can find our Bluetooth receiving devices in the products listed here: https://www.crutchfield.com/g_15260/Wireless-Adapters.html?tp=2051 My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=101 [ Paul Aug 08, 2018 ] Staff

No, it does not. [ KENNETH Jul 29, 2018 ]
Samsung's website and the description on Crutchfield both indicate this TV is HDR. If you purchased this TV and are having issues, perhaps you should contact Crutchfield or Samsung. If you have not purchased this TV, perhaps you should not assume that it will not display HDR content. I purchased this TV a few weeks ago and after some very minimal tweaking of the picture adjustments, the picture is exceptional for a relatively inexpensive TV. [ KENNETH Jun 20, 2018 ]
The power supply is within the TV chassis itself; there is no external transformer or "wall wart" on the power cord. [ BRIAN Jun 03, 2018 ]
It is just a standard 2-conductor, 120 Volt cord with a right-angle plug for the wall socket. It plugs into the rear of the TV with a connector similar to that used on computer charging transformers. There is no "power brick" (transformer) involved. [ DIY Dick Jun 02, 2018 ]
