Mobile Entertainment, better on TV

Ever wish you could watch your favorite mobile content full screen on your TV" The all-new Sero makes that dream a reality.

TV that moves to fit your content

The Sero's screen rotates so you can watch your favorite content whether it's in portrait or landscape. Whether vertical for mobile content and apps or horizontal for movies and TV shows, you'll always have the best viewing perspective.

Tap to mirror content

Simply tap your phone to your TV to seamlessly start casting content. It's never been easier to watch mobile content on the big screen.

Mobile content just got bigger

No more black bars when you play a mobile video on your TV. The Sero displays an optimized aspect ratio so you can enjoy content, apps, and social media on the entire screen.

Control your home with SmartThings

The Sero works with SmartThings to put you in control of your smart home. The Sero links with IoT devices and sensors so you can turn on the lights, check what's inside your fridge, and even run the robot vacuum cleaner right from the comfort of your couch.

Works with AirPlay 2

With AirPlay 2, you can stream or share content from Apple devices to the big screen. Effortlessly play videos, music, photos and more from your iPhone, iPad and Mac on your Samsung TV.

Portrait Modes

The Sero blends seamlessly into your space even when you're not watching content. Match or redefine any room's ambience with one of five modes - poster, clock, photo, sound wall, or Cinemagraph.

Beyond the black screen

Watch your TV virtually disappear into the walls of your home. Ambient Mode + mimics the wall behind it and elevates your space by turning the screen into décor, artwork, the weather, today's headlines, and more.

So easy to move around

The optional Sero Wheels allow you to easily move your TV so you can enjoy it in any room of the house.

A display as unique as your style

Elegantly minimal with a navy blue stand, The Sero is beautiful from any angle. No matter how you use it, it's a space-saving and stylish addition to any room's design.

Deep, premium sound

Whether you're playing your favorite videos or streaming the latest playlist, The Sero's powerful 4.1ch 60-watt audio system packs a real punch so all your content sounds as great as it looks. Dolby Digital Plus gives you premium sound throughout the room with plenty of bass.

Catch every word without distraction

Background noise from your home can disrupt your viewing experience. Active Voice Amplifier analyzes the ambient noise and enhances the voices in the scene so you can hear the dialogue clearly.

Bring more than a billion colors to life

With 100% Color Volume*, Quantum Dot Technology delivers over a billion shades of color that stay true-to-life without washing out at any level of brightness.

Upgrade what you like to 4K

Now you can get 4K resolution picture, regardless of the source. 4K AI upscaling automatically analyzes the input source to reduce image noise, restore lost detail, and define edges around objects and text.

Surroundings change, picture stays perfect

Whether in a sunlit living room or a darkened den, Adaptive Picture optimizes the TV by analyzing the picture and the room's lighting conditions for an amazing picture - wherever and whenever you are watching.

Rethink what Smart TV can do

Go beyond Smart TV with next-gen apps, super easy control, and a host of enhancements that elevate the TV watching experience.

Best TV I've ever had!

Submitted by Samham - 11/18/2020

My new Samsung Sero is incredible! Sharing my phone screen with my TV rotated to vertical is unlike anything I've ever had. This TV is entirely unique and the picture is gorgeous. I wasn't sure how I would like the rotating screen but it's so easy I love it.

GREAT for TikTok and IGTV

Submitted by K80PV - 11/15/2020

i purchased this tv after seeing someone else use it for workout videos on igtv. i had considered the workout mirror but when i compared the two, i preferred this one so i could also have tv functionality. this has been great for tiktoks as well and the sound quality is amazing. i also purchased the wheels attachment which i highly suggest if you ever want to move this tv. it is very heavy.

Sero a serious next generation product

Submitted by Kris2020 - 11/14/2020

Sero is the most innovative product of this year Here are the reasons for it: 1. Sound and Screen combo at that price. 2. STYLE statement it makes. 3. Can be moved to any room. 4. Robust design 5. No wall mounts or stand. 6. Mobile phone mirroring capability 7. Can be used as monitor no desk needed, it stands on its own. Expectation: 1. Put on a camera on it. 3. Try with little bigger screen 4. Add wired ethernet port.

Best bedroom screen you can get

Submitted by Shelby - 11/12/2020

When I told my family about getting a new TV, they didn't appear to be excited. However when we unboxed the sero, everyone wowed. It's unique. We all love it. Portrait and landscape. Now sharing a video I take in portrait is a family event we do everyday. 3 days after we got it, we start to share interesting webpages we found on our phone. I am shooting more portrait videos and this is a family time changer in this long, boring covid time. 4K QLED is stunning and the color is especially outstanding on this cute 43 inch. We keep the new Sero in our bedroom. It stands on its own and fits so well in both portrait and landscape modes. The sound is very well tuned, a 4+1 channel is much better than any other TV on the market. TV-plus from Samsung gives us free news coverage so we could save the cable cost. Overall very happy with it. Would like to see a more artistic ambient mode like the frame-tv has, and more customizable interface to use as a home information stand. Well done and keep innovating!

"A Problem occurred during Rotation..."

Submitted by Nanurunerk - 11/9/2020

43" Class The Sero QLED 4K UHD HDR Smart TV QN43LS05TAFXZA When rotating from PORTRAIT to LANDSCAPE an audible indicator followed by a pop-up ERROR MESSAGE: "A Problem occurred during Rotation. Please solve the problem and try again." An End User solution is required in order to achieve LANDSCAPE by the application of consistent pressure to edge of TV Screen guiding the direction of the rotation. However, if this application by the End User is interrupted before the rotation to LANDSCAPE completes the screen orientation immediately returns to PORTRAIT.

Great picture!

Submitted by MovieLover6293 - 10/27/2020

The picture quality is more than I expected. It made for a great upgrade from our older Samsung TV that finally gave up after years of dedicated service. Even though we have an older sound system, connecting was a cinch. We were up and running in no time. We played one of our old blue rays and it was like watching it for the first time.

Not for APPLE users

Submitted by tv consumer - 10/26/2020

unfortunately, we were told by the salesperson that this tv would work great with apple iphone. however, not true, it only works with apple in "landscape" mode. this defeats the cool factor. after getting this item home, i asked several more salespersons what samsung products i could buy that would be compatible. he said it would only be compatible with a samsung phone with a "celluar" service. so i would need to purchase a separate line just to get the cool factor use from the tv. what?!? would love any expert advice from samsung, but was passed along to 3 separate customer service #'s. no one had an answer. i am a very loyal samsung customer!

I prefer a remote with more visible control buttons. The supplied remote is difficult for technologically disadvantaged Senior citizens utilize full range of capabilities.

Almost perfect!

Submitted by zuko - 10/9/2020

bought it on impulse, as soon as i saw as this was unique and bold.i don't watch a lot of tiktok videos. ebooks looks stunning on this tv. being able to project windows pc to this tv is a huge plus. for zoom calls, i am able to project the zoom window from my windows pc to the tv and use it as extension to my laptop screen and keep my laptop screen for browsing while on the call. however, couple of nice things to have. 1) while smartthings app on my samsung galaxy s5e works flawlessly, i'm unable to mirror my pixel 3xl using smartthings app. 2) if the tv had a camera and microphone built in (microphone is on the remote though), one could use it as a giant screen smart device by itself to make google duo or echo video calls.

Submitted by EvLovesFlowers - 9/21/2020

Before this tv, I had an Scientology's old one that happened to break. But since this tv is a smart tv it was something completely useful that has enhanced my life. I can basically use my cell phone like a remote. 10/10 would recommend
