Like Smartphones, Mi has redefined the LED TV market with it’s first LED TV the Mi LED Smart TV 4. We have reviewed the Mi TV 4 with complete details to cover the exciting features this truly smart TV offers.

The Mi TV 4 has a brilliant minimalistic design. The slim panel is supported by a single sheet of brushed steel at the back. Mi LED Smart TV 4 is the world’s thinnest LED TV. At the thinnest point, the television is only 4.9mm thin. The thickness of the TV is more at the bottom because this is where all electronic parts are placed.

The table top stand is made of Aluminium Alloy and is extremely sturdy.

This is a sheer work of technological excellence and has raised the bar for all LED TV brands. There is no LED TV in India which comes even a little closer to this. Get ready for a never experienced and truly unique TV viewing.

Frameless Display
Immersive viewing experience got a new meaning with this large screen 55 inches TV. The Frameless Display gives you a theatre like experience with no boundaries to limit your view.

The Mi TV 4 uses a premium 54.6 inch Samsung VA panel. It has a static contrast ratio of 6000:1 and a viewing angle of 178 degrees. With a 3820 x 2160 pixel resolution, the screen offers a refresh rate of 60Hz.

Image Technology
The 4K+HDR technology gives you a true life-like picture clarity and brightness. The colours seem so vivid and even the tiniest of details are so visible. Enjoy your favourite TV shows and movies with rich and crisp details.

Sound Output
Mi LED TV 4 comes with two downward firing 8 Watt speakers which makes the total audio output 16 W. Mi Smart TV 4 also features Dolby Audio and DTS-HD.

For a TV as good as Mi TV 4, we believe this is one area where Mi could have done better. The audio output is okay if you are watching the TV in a small or mid-size room. Don’t expect the theatre like experience in terms of sound if you are watching a 4K movie or video. If you want the true theatre like immersive experience then we would recommend investing in good quality soundbar or speakers.

The sound from the built-in speakers is clean and noise-free and is sufficient if you are watching regular TV shows or news.

Mi LED TV 4 is powered by a 64-bit quad-core processor. 2 GB RAM makes multi-tasking easier and let’s you switch between multiple apps effortlessly. The TV also comes with an internal storage of 8GB, you can use this for storing music, videos, movies or download some more apps.

Marketed as the biggest USP of Mi LED TV 4, Patchwall offers a revolutionary Smart TV experience. And you will realize the difference the moment you switch on this TV. Unlike most Smart TVs which only focus on apps, this TV puts the prime focus on content like Apple TVs tvOS.

The TV greets you with a dashboard of content with over 500,000 hours of content from the built-in content providers like Hungama, Zee5, Sony Liv, Hotstar, Voot etc.

The game changing feature that PatchWall offers is Mi TV 4 can display content not only from the streaming services but from your Set Top Box as well. This TV displays a tile interface for the channels and you can search for TV shows, let’s say Dance India Dance, Master, and the TV will automatically searches for the content on the built-in apps and the set top box.

It will display when the show will play, the current run duration of the show and also the remaining time. To our surprise, Mi TV 4 is compatible with all the set top boxes available in India (over 3500 DTH and set top box providers).

However the Patchwall doesn’t support popular streaming services like Amazon Prime Videos and Netflix at present. Patchwall OS is based on Android but it doesn’t support YouTube and Google Play Store at present. The TV comes with an internal storage of 8GB and you can try to Side-load (install manually using apk file of app) the Google Play Store and other apps. However, side-loading an app is troublesome and there is no guarantee that the app will work as desired.

Patchwall not only let’s you search for your favourite content, but also recommends content based on your past viewing with the help of Artificial Intelligence. So if you watch comedy shows/movies the interface will automatically recommend comedy movies and videos.

The PatchWall is still in it’s initial stages and we expect many more features will be offered as updates in the future based on the user feedback.

Mi LED TV Smart TV 4 comes with 3 HDMI Ports (one HDMI Port is ARC), 2 USB Ports (1 USB 3.0 and 1 USB 2.0), Ethernet Port, AV input and dual-band Wi-Fi and Bluetooth 4.0 (Low Energy). This TV gives you multiple options to connect your smart devices and storage devices to enjoy your favourite content. You can also browse the web, connect on social networks and stream videos and movies online with wireless Internet connection.

Another standard feature that is missing is a headphone jack so if you already have a soundbar or speaker that supports 3.5 mm jack or RCA connection then you won’t be able to connect them to TV. You will have to buy a Coaxial Digital Adapter Cable if you want to connect soundbar or speakers that have 3.5mm or RCA connections.

Screen Mirroring
This TV also comes with screen mirroring feature that lets you cast content from your smartphone or tablet on to the bigger screen of your TV. You can also control your TV with your phone, but this feature is only supported if you have an Android phone connected to the same Wi-Fi network as the TV.

One Remote
Like the complete TV, Mi has gone for a true minimalistic design for the remote control as well. Unlike most smart TV’s remote controls which have as many buttons as the cockpit of a plane, Mi LED TV 4’s remote control has less than 10 buttons. And the best part is you can use it as a universal remote to control both TV and set top box.

The remote pairs to the TV via Bluetooth so all the TV functions will work without you having to point the remote to the TV. But please note that the set top box functions are controlled with the help of an IR controller cable (included with the TV) so for controlling the set top box functions you will have to point the remote like the conventional ones.

Mobile App
Another interesting feature of Mi LED Smart TV 4 is a mobile app that can control the Mi TV. This remote-control app also lets you take a screenshot of the TV and save the screenshot directly on your phone. You can also open apps on your TV from the convenience of your phone.

Very soon you will also be able to download apps on your smartphone and if they are compatible with the TV, you will be able to launch them from this apps menu. The app also lets you use your smartphone as a controller for playing games on the TV.

Some remote functions may not work if your smartphone does not have an IR blaster.

Our Verdict

Every single Rupee spent on this TV is worth it. At a price of Rs. 39,999 there is no competitor that matches the features and class of this TV. Best of luck for grabbing one during the next flash sale on Flipkart.
