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 lacklustre due to the lack of local dimming, wide color gamut, and low HDR peak brightness.
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 screen, like football fields, the issues generally go unnoticed by most.
Pro Intuitive & 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 suport @ 60 FPS, which makes it suitable for all new 4K games.
Pro Colors are easy to calibrate
Color calibration can be performed easily via the Roku mobile app. You won't have to fiddle with the remote trying to set the values correctly.
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 personalisation can be limited through the TV's settings.
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 makes 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.
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 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 Perfect TV for movies and HDR content
The Sony A1E is a 4K OLED TV with perfectly uniform blacks and infinite contrast ratio, achieved by its ability to manipulate pixels individually. This, along with its color uniformity and wide color gamut, gives it exceptional picture quality and makes it the perfect choice for movies. It also has no issues with brightness levels as the panel can reach up to ~650 nits of brightness when playing HDR content, and it handles reflections very well.
Pro Great performance in bright environments
The Sony A1E has a practical peak brightness of ~650nits for both SDR and HDR content — it can sustain this level of brightness when playing content. While the number here isn't imposing compared to some other high-end TVs, the panel of this TV offsets this by being an OLED. It can handle reflections very well and will not have any issues with fighting light in bright environments.
Pro Interface is ads-free
The user interface of modern smart TVs can include some advertisements similar to those on the internet or in a mobile app. The Sony A1E does not include any, and it also has a feature for limiting ads in third-party applications.
Pro Virtually no reflections
The Sony A1E's panel has a glossy finish that handles reflections exceptionally well.
Pro Great ecosystem of third-party apps
The Sony A1E runs on Android TV — normal Android apps from the Google Play Store (or other app stores) will work on it.
Pro Extremely low motion blur
As the Sony A1E has an OLED panel, it has near-perfect pixel response time; the motion blur is virtually non-existent at sub-1ms, which means this TV will have no issues with displaying extremely fast-moving objects — they will look smooth without any blur or lag.
Pro Excellent for dark rooms
The Sony A1E performs exceptionally well in dark environments. Its ability to produce absolute and perfect blacks means the reproduction of dark highlights and scenes in movies will look great — this is further improved when there's no light around the TV as it allows the blacks to stand out more. This makes it great for watching all sorts of movies in a cinema-like setting, particularly movies with many black highlights/scenes where this is immediately noticeable even to undiscerning viewers (e.g. Interstellar).
Pro Decent sound quality
The sound quality of the Sony A1E is surprisingly good for a TV (which isn't known for having excellent sound). The speakers can get really loud without much distortion happening, and its frequency response is perhaps one of the best measured in a TV's speakers. While an external audio set-up will be better, the built-in speakers should suffice for most users that don't wish to spend additional money on an audio set-up.
Pro Dark scenes are perfectly reproduced
The Sony A1E can handle dark scenes very well thanks to its OLED panel which gives it infinite contrast ratios — it can reproduce dark scenes perfectly because of this.
Pro Wide viewing angle
The picture quality of the Sony A1E does not suffer from much deterioration when viewed from other angles. The brightness will decrease with deviations in viewing angles, but the black levels seem to be maintained perfectly.
Pro Decent for gaming
Input lag is one of the most important factors when considering a TV for gaming — it's representative of how fast the TV can display the image after receiving the input. The Sony A1E has ~30-40ms of input lag, which is decent enough for most gamers, but competitive gamers might find this lacking.
Pro Excellent for watching sports
The Sony A1E's versatility is top-notch. The motion blur along with great overall color uniformity makes it an excellent choice for sports.
Pro Great color reproduction
The color gamut of a TV refers to the range of colors the display can reproduce — the wider the color gamut, the more colors it can display, and the better the overall picture quality will be. This is extremely important for HDR content because it requires a much broader color gamut than SDR content. The Sony A1E has no issues with accurately reproducing the colors necessary for true HDR.
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 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 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 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 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.
Con Suffers from image retention issues
The main drawback of OLED panels are image retention issues with static images — pixels on the panel gets burned in when the picture doesn't change for extended periods of time. Noteworthily, the static image doesn't have to be whole like a full wallpaper on the TV; it can happen with content that has a static image anywhere on the screen.
As the Sony A1E has an OLED panel, it, unfortunately, suffers from this problem. There might be some retainment of artifacts for ~10 minutes when this happens, and it usually goes away after watching other content without static images. It's worth noting that while this issue is present, the Sony A1E reportedly handles this pretty well — most users report the artifacts going away only ~5minutes of playing traditional content.
Con Might be hard to access inputs when mounted to a wall
The Sony A1E is extremely thin, and it has a reflective finish on the back. After mounting it to a wall, the inputs might be hard to access, and because of the reflective finish, it can pick up fingerprints/smudges when attempting to access the inputs (which also becomes hard to clean because of how thin it is).
Con Lacks support for Dolby Vision
The Sony A1E can currently only play HDR10 content. It does not support Dolby Vision.
