The MU9000 can produce really detailed pictures, especially in dark scenes thanks to its really deep black levels. It has a contrast ratio of about 6000:1, which enables it to produce blacks that are 6000 times darker than the brightest white.
The colors are lifelike and accurate even without any calibration by the user. They will look really vibrant even in bright scenes because of the panel’s high peak brightness levels of ~400 nits for SDR & ~450 nits for HDR.
Even in a decently-lit environment, the MU9000's picture quality can still hold up - the panel is excellent at handling reflections thanks to its glossy finish, and it can get bright enough to fight off glare.
Pro Excellent at handling glare
The MU9000's panel has a glossy finish that reduces reflections significantly. This makes it excellent at fighting glare, along with its adequate brightness levels of ~400 nits for SDR & ~450 nits for HDR.
Pro Capable of smooth 24p content playback
The MU9000 is great at dealing with 24p content, such as Blu-rays or media sourced from a cable or satellite box. It can detect and eliminate the judder effect present in these content, where images displayed can appear jittery.
Pro Inputs are very accessible
The MU9000 comes with a OneConnect box which moves all the hard-to-access rear inputs away from the TV. Thanks to this, you’ll always have full access to all inputs and outputs of the TV even if it’s wall-mounted. The OneConnect box can also be used as a USB charging hub.
Pro Intuitive user interface
The MU9000 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.
Pro Great at up-scaling low-res content
The MU9000 can upscale 480p, 720p, and 1080p content to 4K quite well. The upscaled content has almost no noticeable artifacts, and all the details are preserved.
Pro Suitable for gaming and watching sports
The MU9000 is pretty versatile. On top of its great picture quality, it has features that make it perform quite well for gaming and sports.
It offers a responsive and fluid gaming experience - players will have no issues keeping their actions in sync with what’s on the display, and fast-moving objects won’t leave any trails on the screen. That is thanks to the low input lag of ~25ms and the panel’s quick response time of ~15ms, which results in virtually no motion blur.
It’s also great for watching sports because of the virtually non-existent motion blur that makes fast-moving objects, like football, look smooth. The panel is also pretty uniform - it has also had no issues with displaying large, same-color objects on the screen, like football fields.
Pro Remote has a voice command feature
The MU9000'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.
Pro Good for HDR content
On top of its great picture quality, the MU9000 has a high HDR peak brightness level and wide color gamut that makes it good for HDR.
Shadows look pretty good with nice details, and highlights are quite vibrant thanks to the peak brightness level of ~450 nits.
The panel can reproduce the wide range of colors required for true HDR playback because of its wide color gamut, which covers ~60% of the standard colors required for HDR according to the Rec. 2020 color space. This is considered decent enough for reproducing HDR details, and it can display these colors accurately at different brightness levels.
It’s worth noting that while the MU9000 has local dimming that’s supposed to make HDR better, the local dimming is crap and doesn’t do much - it increases the contrast ratio by a meager amount and does nothing else.
Pro Decent for casual movies/TV watching
The S405 is a decent, affordable pick if you're a casual viewer. You'll get decent picture quality and a good 4K experience, but the HDR performance might be lackluster due to the lack of local dimming, wide color gamut, and low HDR peak brightness.
Pro Excellent value for money
The S405 strikes a nice balance between picture quality, screen size, and input lag, all for an affordable price of below $500. It's a great choice for watching and gaming casually without breaking the bank.
Compared to its direct competitors, it offers decent picture quality that is a tad below them, bigger screen size, and lower input lag.
Content looks decent enough for most casual viewers - the black levels are sufficiently deep, colors are vivid, and it gets bright enough for most types of content in a dark room.
The size difference is pretty huge as options with similar size of 49", or even smaller, cost fairly more than the S405.
Its low input lag of ~15ms contributes to a more responsive gaming experience. It's barely noticeable, and it’s also one of the lowest among 4K TVs, which is an impressive feat in this price bracket.
Pro Works well as a computer monitor
The S405 works well as a computer monitor thanks to its low input lag, barely noticeable motion blur, and full 4:4:4 color support. The 43" model can even be used up close due to its small minimal viewing distance.
The low input lag and low motion blur of ~15ms makes it highly responsive to input and gives it the ability to handle dynamic content well.
It also has full 4:4:4 color support, so text or shapes with hard edges on the screen won't be blurry.
Pro Decent for watching sports
The S405 is a good pick for watching sports thanks to its low motion blur and reasonably consistent color uniformity.
Fast-moving objects, like footballs, won't leave any visible trails on the screen due to the low motion blur of ~15ms. While there are slight uniformity inconsistencies in the edges of the panel when displaying large, same-color objects on the screen, like football fields, the issues generally go unnoticed by most.
Pro Intuitive and smooth user interface
The S405 runs on the Roku TV smart platform, touted for its simple, straightforward, and lag-free UI.
It’s easy for anyone to grasp how navigation works, thanks to its two-column design with the menu on the left and options on the right.
There’s also no noticeable lag during navigation or menu selection.
Pro Excellent for gaming
The S405 is excellent for gaming - the overall experience will be very responsive and fluid, thanks to the really low input lag and barely noticeable motion blur.
It has an input lag of ~15ms that makes the TV highly responsive to user input - gamers will have no issues keeping their actions in sync with what's on the display. The panel can fully change its pixels color in under 15ms, resulting in fast-moving objects not leaving any trails on the screen, eliminating virtually all motion blur.
It's also suitable for HDR gaming because there is no increased input lag for HDR, and it has full 4K support @ 60 FPS, which makes it suitable for all new 4K games.
Pro Main interface has no ads
The S405 has no ads on its main interface, although there can be ads in third-party applications. Third-party ads can't be blocked, but the tracking and personalization can be limited through the TV's settings.
Pro Colors are accurate even without calibration
The S405 is excellent at reproducing colors accurately out of the box.
Even without calibration, the colors are spot-on - they're very close to what the source signal demands and any inaccuracies are generally considered imperceptible to most end users.
The overall average difference between the source signal and the panel's reproduction of the color is measured in Delta-E, where lower means better accuracy. The S405 has a Delta-E of below 2.0, and anything below 3.0 is generally considered accurate for most end users.
Pro Decent picture quality
The S405 looks decent with adequately deep black levels, above-average color accuracy, and sufficient peak brightness levels for most content.
It’s especially great at reproducing dark scenes thanks to the panel’s contrast ratio of about 4000:1, which means blacks can get really dark at about 4000 times darker than the brightest white it can produce.
Colors are spot-on even without calibration, and the panel can get bright enough with a peak brightness level of ~200 nits to make them pop in dark environments.
The best viewing experience will be in a dark environment where the panel won’t have to compete with light. The S405’s screen can’t really get bright enough to perform as well in bright environments.
Pro Well-balanced side inputs
Even when the S405 is mounted on a wall, you'll still have access to all essential inputs and outputs which are situated on the side of the unit.
Pro Highly versatile
The S405 is versatile enough to be used as a general-purpose display.
The picture quality is decent for movies and TV shows, and it checks all the boxes that make a TV suitable for gaming, sports, and as a computer monitor: low input lag, low motion blur, good screen uniformity, and full 4:4:4 color support.
Con Not suitable for group watching
The MU9000 has a narrow viewing angle that makes it unsuitable for watching with groups.
Audience sitting away from the center of the screen will not experience the same picture as those sitting in the center, because the picture quality starts to deteriorate significantly when viewing from just ≥20° away from the screen's center - the colors will start looking dull and blacks will look like greys.
Con Lacks support for Dolby Vision
The MU9000 currently only supports the HDR10 format for HDR content.
Con Interface has ads
There are ads that can't be removed on the MU9000's interface.
Con Mediocre sound quality
The sound quality of MU9000's built-in speakers is mediocre. It sounds quite bassy and the clarity is reduced at higher volumes - you might have a hard time following dialogues at higher volumes because of this. There’s also distortion at higher volumes.
Con Not really high value for money
The MU9000 is a great TV, but the retail price can be off-putting for some because the picture quality and features it offers are present in other similarly-priced models, e.g. the Sony X900E. This TV can be really worth it when on sale, or if Samsung offers better after-sales service in your region.
Con Can't fight glare very well
The S405 can deal with low amounts of light, such as sunlight through curtains, but it won't be able to deal with significantly bright light.
Apart from being unable to get bright enough, its handling of reflections is only average. The panel has a semi-gloss finish which helps in reducing reflections a little, but its peak brightness level of ~200 nits is not enough for fighting glare.
Con HDR support is basic
The S405 can't reproduce HDR pictures very well because it lacks various important features.
HDR won't look much different from SDR due to the lack of wide color gamut and low peak brightness. It can't reproduce the full range of colors necessary for HDR, and the brightness level of only ~200 nits is barely enough for HDR content to stand out.
The black levels are also insufficient for highlights to stand out, and it won't be as dynamic as one would expect for HDR due to the lack of local dimming.
Con Poor sound quality
The speakers on the S405 are too bassy, so distortion becomes a huge problem at high volumes. A relatively cheap speaker system or a soundbar will make a huge difference in sound quality.
Con Remote lacks functionality
The S405 has a basic remote that is only capable of navigation, playback control, and volume control. It doesn't have fancy stuff like voice command found in remotes of other TVs.
Con Lacks support for Dolby Vision
The S405 only supports the HDR10 format for HDR content.
Con Not suitable for group watching
The S405 has a narrow viewing angle that makes it unsuitable for watching with groups.
People sitting away from the center of the screen will not experience the same picture as those sitting in the center because the picture quality starts to deteriorate significantly when viewing from just ≥30° away from the screen's center.
