Samsung MU7000 Series 40" (UN40MU7000) vs TCL S517 55" (55S517)

The MU7000 is a great well-rounded option for watching movies, gaming, and sports. Its picture quality is decent, it has low input lag and low motion blur, and the screen uniformity is great. It can also be used as a PC monitor.

The MU7000's remote has a voice command feature that can perform actions as you physically would with the remote, and it can even be used to adjust settings directly.

The MU7000 runs on the Tizen smart platform, known for its simplicity and intuitiveness.

It’s easy to navigate and access all the functions of features of the TV - the whole menu of the Tizen OS is organized around a menu known as the “Smart Hub” which contains everything: apps, settings, input switching, etc.

It also has a section for quick access to frequently used items.

The MU7000 is a decent pick if you're a casual viewer. You'll get a great 4K/SDR experience, but the HDR performance might be lacklustre due to the lack of local dimming and low HDR peak brightness.

The MU7000 is decent for gaming thanks to the fairly low input lag and barely noticeable motion blur. Its input lag of ~20ms contributes to a responsive gaming experience, and the panel's response time of ~20ms means it can handle motion fairly well - most don't notice any visible trails behind fast-moving objects.

The MU7000 is suitable as a PC monitor because of its relatively small screen size of 40". It can be used up front thanks to the small minimal viewing distance, and it has full 4:4:4 color support that ensures text or shapes with clear, hard edges are not blurry.

The MU7000 looks good with really deep black levels and sufficient peak brightness levels for most content.

Dark scenes look amazing thanks to the panel’s contrast ratio of roughly 6300:1, which means it’s capable of producing blacks that are 6300 times darker than the brightest white pixel the screen can produce.

It gets bright enough for SDR content with a peak brightness level of ~350 nits, which is sufficient for making colors pop.

The best viewing experience will be in a dark environment where the panel won’t have to compete with light as the MU7000’s screen can’t get bright enough to perform as well in bright environments.

In terms of picture quality the S517 is comparable to high-end TVs. It displays remarkably deep blacks due to its great contrast and reproduces details in color very well due to its good color gradient.

The 6000:1 native contrast ratio allows the TV to reproduce dark scenes particularly well. It is easily one of the best in this price range – it’s often compared to high-end counterparts.

The S517 has superb black uniformity and contrast that create pleasant, deep blacks. They are much better than those of the similarly-priced competitors. The maximum deviation sits at around 1.02% .

The TV is good at capturing small differences in color such as skin tones, green colors in nature, details in shadows, etc. This is because of the color gradient, which is on par with other options of the same price. There is almost no banding and the standard deviation of color doesn't go past 0,11%.

The S517 is fit for all gamers because it offers a clear, lag-free experience. The TV is very responsive - it has struck a good balance between decent refresh rate, solid input lag, and good response time.

The TV is an ideal choice for console gaming in terms of its native refresh rate. It caps at 60Hz, which is perfect since most games won't benefit from anything higher than this.

The S517 is fast. An action shows on the screen in around 18 miliseconds, which can make the difference between managing to get a frag or waiting for a respawn. The time doesn't substantially increase when gaming in HDR or 4K either - it goes up to roughly 20.5 ms. The only thing to remember is to keep "_Game_" mode enabled for the lowest possible input lag.

The TCL S517 also handles motion and fast-paced content quite well, it has a good response time. This makes sure you can keep up with fast-moving objects and a lot of action without it all appearing blurry. A full pixel color transition takes only 15.8 ms.

The mobile remote app for both iOS or Android can fully and comfortably substitute the real remote – launch apps, input text in apps, control most TV settings, etc.

Also, colors can easily be adjusted close to perfection thanks to the app’s calibration menu.

The S517 comes with the Roku TV smart platform, which provides a comfortable interface and a big app selection.

The interface is quite basic and easy to overlook. It’s smooth and simple to swap to your favorite apps.

Roku TV offers a huge app store with all the most popular apps – Netflix, YouTube, Hulu Plus, Amazon Instant, HBO Go, Vudu and much more. Some apps are even absent from other TV manufacturers Smart TV platforms and unique to Roku.

The picture quality when you first open the TV up is quite decent. The only settings that could potentially require tweaking are grey inaccuracy and color inaccuracy. Either way, these are things that most people won't even notice.

The S517 offers a pleasant PC monitor experience not only due to the good responsiveness, but also because of the video signal's compression.

The TV won't make text appear blurry while connected to a PC because the signal has no compression and transports color data and luminance fully. This is also known as chroma 4:4:4, and the “_Computer_” and “_Game_” modes display it properly at 60Hz.

All of the inputs are conveniently placed on the side of the S517, so you won't have to worry about leaving space between a wall and the TV.

The S517 offers the possibility to make movement in videos smoother, also known as the "soap opera effect". This is done by making the TV take two frames and try to guess what would a frame in between of those look like, also known as motion interpolation. The frame rate can interpolate up to 60 frames per second.

The S517 does a reasonably good job with upscaling most content to 4K quality, be it 480p DVDs, HDTV or full HD Blu-rays.

The TCL S517 is a decent option for pretty much everything, be it gaming, movies, sports, or HDR content. It has noteworthy picture quality, good all-around responsiveness, decent smart features, nice motion handling, and, most importantly, a great price.

The S517 is a much better fit for HDR content and HDR gaming than its competitors due to the wide color gamut, decent color depth, and high contrast.

The TV can display a lot more colors than its similarly-priced counterparts. The coverage of the Digital Cinema P3 color space is very good - 90%.

The color depth is on par with competing options. The S517 has 10-bit color depth, which means that it can display approximately 1.07 billion colors in total. This is important for HDR content because HDR media takes advantage of 10-bit.

The S517 can display deep blacks in the HDR mode because of it's high native contrast ratio of 6000:1, which is easily one of the best in the given price range.

The TV can also play all HDR content, because it supports both standard formats of HDR - HDR10 and Dolby Vision. They enhance the viewing experience by editing the metadata, that is, the extra information that tells the TV how to display HDR. The formats differ in the way they deal with it however - Dolby Vision edits the picture on a per scene basis, whereas HDR10 edits everything at the start of the video.
