TCL S405 43" (43S405) vs Sony A1E OLED 77" (XBR77A1E)

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.

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.

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, uniform objects on the screen, like football fields, the issues generally go unnoticed by most.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

The Sony A1E's panel has a glossy finish that handles reflections exceptionally well.

The Sony A1E runs on Android TV — normal Android apps from the Google Play Store (or other app stores) will work on it.

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.

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).

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.

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.

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.

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.

The Sony A1E's versatility is top-notch. The motion blur along with great overall color uniformity makes it an excellent choice for sports.

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.
