VIZIO M-Series 50" (M50-E1) vs Sony X850E 65" (XBR65X850E)

The M-Series is the best pick for HDR content in this price bracket. Compared to its direct competitors, it offers the best HDR experience because it has all the essentials for true HDR playback that its competitors lack: local dimming, fairly high peak brightness level, and a wide color gamut.

Its deep 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 a slight increase in overall picture quality - the black levels become deeper by a small margin, so highlights will stand out further.

Colors look vibrant in both dark and bright scenes, and the panel can reproduce the wide range of colors required for true HDR playback. In addition, it can also get bright enough to light up these colors sufficiently for HDR details to stand out, thanks to the peak brightness level of ~400 nits.

The M-Series can play all HDR content because it supports both HDR10 & Dolby Vision formats.

The M-Series looks great with vivid colors.

Dark scenes look amazing with great details, thanks to the panel’s contrast ratio of roughly 5500:1, which means it’s capable of producing blacks that are 5500 times darker than the brightest white pixel the screen can produce. This can be pushed slightly further to about 5800 with local dimming, which results in a slight increase in overall picture quality.

The colors are quite lifelike and accurate even without any calibration. They will look vibrant even in bright scenes because of the panel's high peak brightness levels of ~300 nits for SDR & ~400 nits for HDR.

Even in a decently-lit environment, the picture quality of the M-Series won't deteriorate by much. The panel is good at handling reflections and it can get adequately bright to fight off glare.

The M-Series is decent in bright environments.

The colors won't look dull thanks to the panel's high peak brightness levels and good handling of reflections. It's bright enough to fight off glare with peak brightness levels of ~300 nits for SDR & ~400 nits for HDR, and the intensity of reflections are reduced by panel's semi-gloss finish.

You can stream content to the M-Series from smart devices or apps that support streaming media to Chromecast.

The M-Series runs on VIZIO's SmartCast OS which has a brilliant, well-integrated phone and tablet app for iOS & Android. It can turn your smart device into a fully-functional remote, which makes it easy and convenient for you to control the TV without the physical remote. It's also particularly handy for text input, especially when it comes to searching for content from streaming services.

The M-Series has no ads on its interface.

The X850E is an excellent option for those who watch content from an antenna/satellite box, DVD/Blu-ray player or Apple TV. It can detect eliminate jerky playback that is common in content from these sources.

The X850E has the largest screen size at 65” for the cheapest when compared to its direct competitors. Similarly-sized models from its direct competitors cost much more.

The X850E has a wide color gamut that allows it to reproduce the colors necessary for true HDR, and it has an average peak brightness level of ~400 nits that allows it to light up these colors properly. Thanks to that, HDR pictures look decent and highlights will look fairly good.

However, the HDR performance can’t get better than that, due to the average peak brightness of ~400 nits which isn’t really enough for details to truly stand out, and it lacks local dimming.

The X850E 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.

The X850E looks fluid thanks to its excellent color uniformity and decent handling of motion.

It can display large, same-color objects like football fields really well - they will look natural and uniform.

Fast-moving objects, like football, will also look smooth. The panel only requires ~14ms to fully change the pixels color, resulting in fast-moving objects not leaving any trails on the screen, eliminating virtually all motion blur.

The X850E looks really good in dark scenes, thanks to its decent contrast ratio of 4500:1 and excellent black uniformity.

It can produce blacks that are 4500 times darker than the brightest white, and the black uniformity is especially good - there’s barely visible flashlighting, where edges of the screen has light on them when displaying a black image, and the screen is evenly bright. This makes it perform really well in dark scenes.

Colors look vibrant because of the panel’s high peak brightness levels of ~350 nits for SDR & ~400 nits for HDR. With these brightness levels, it can get bright enough to fight glare. Along with its great handling of reflections, pictures will still look good in decently-lit environments without dull colors.

The X850 has a relatively low input lag of ~35ms that makes it a decent pick for gaming. Most players will feel in sync, however, it might be a little unresponsive for competitive or demanding gamers.

It’s also acceptable for HDR gaming because the input lag does not increase in HDR mode.

There are no ads on the X850E’s interface.

The X850E can increase the framerate of content to either 60Hz or 120Hz.

It guesses which frames are missing based on the previous and next frame, and inserts the missing frame in between them. This produces a really strong soap opera effect, where images look really smooth.

This might look weird to some people that doesn't like it, but the X850E can do this really well for those who enjoy it.
