Sony X900E 49" (XBR49X900E) vs TCL S405 43" (43S405)

The X900E looks true-to-life with really deep blacks, clear details, and captivating colors.

Pictures look realistic with lots of details. There’s great depth to them and you’ll be able to see everything in the picture stand out.

Dark scenes are excellent with nice shadow details that are not overly dark to the point where some details get drowned out. This is thanks to really deep black levels, enabled by the panel’s contrast ratio of about 5500:1 which means it can produce blacks that are 5500 times darker than the brightest white. This can be pushed even further to over 6500 with local dimming.

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 ~500 nits for SDR & ~550 nits for HDR.

Even in a decently lit environment, the X900E’s picture quality can still hold up as the panel is great at handling reflections and it can get bright enough to fight off glare.

The X900E runs on Android TV that has Google Assistant. It has voice commands that are pretty useful as you can open apps with it, ask for the weather, and even turn the TV off.

The X900E can upscale 480p, 720p, 1080p content to 4K with no issues. All the details are preserved and most won't notice any imperfections.

The X900E's panel has a semi-gloss finish that significantly reduces the intensity of glare.

The X900E runs on Android TV that has access to the Google Play Store. The Play Store has a nice selection of apps, but normal Android apps won't work unless they support Android TV.

There are no ads on the X900E's interface.

The X900E can display fast-paced or rapidly-moving objects very well without any trails behind it. The panel only requires ~11ms to fully change the pixels color, which eliminates virtually all motion blur. It also has a native refresh rate of 120Hz that makes images look smoother.

Apart from being an excellent TV for movies, the X900E is a decent choice for gaming and sports thanks to its decent input lag, low motion blur, great screen uniformity, and a 120 Hz native refresh rate that makes images look smoother.

The input lag of ~35ms is sufficient for most gamers, apart from competitive ones, to stay in sync with what's on the screen. The low motion blur of ~11ms and a refresh rate of 120 Hz ensures that everything will look smooth - fast-moving objects won't leave any trails on the screen.

It’s also viable for watching sports because the panel also has no issues with displaying large, same-color objects on screen, like football fields.

Even in a decently lit room, the X900E's picture quality will remain more or less the same as in a dark room.

The colors will still look vibrant because the panel is bright enough to fight off glare. It has peak brightness levels of ~500 nits for SDR & ~550 nits for HDR, and reflections are also significantly reduced by the panel's semi-gloss finish.

On top of the excellent picture quality, the X900E has everything essential to an immersive HDR experience: decent local dimming, great coverage of HDR colors, and high HDR peak brightness level.

Its excellent black levels are further improved with local dimming, which can make parts of the screen darker when the image calls for it. This results in an increase in overall picture quality with black levels becoming much deeper, so highlights will stand out further.

The panel can reproduce the wide range of colors required for true HDR playback because of its wide color gamut, which covers ~65% of the standard colors required for HDR according to the Rec. 2020 color space. This is considered great for reproducing HDR details, and it can display these colors accurately at different brightness levels.

Along with the the high peak brightness level of ~550 nits, HDR scenes will look stunning and you'll be able to see HDR details really pop.

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.
