THIS is my first smart tv experience,like many of us ,I was little hesitant to put my hard earn money in this tv.

Excellent Panel but let down by software/bugs :(

Quick review notes on the new 55" 4X Pro TV

Picture Quality
Excellent contrast ratio.
More importantly, the color gradation on the panel is top notch. More often than not, low priced TVs tend to muddle colors, especially grays but glad to report that is note the case with this one
Viewing angles are great, very litle color fade when viewed from the sides

The overall picture quality comes very close to my primary TV which is a Samsung 9 series SUHD (except the backlight bleed - more o...

Nice product

Had it for about 3 weeks. Here are my thoughts and I'll start with Cons.

1. Picture quality is underwhelming out of the box. You will need to dig through a very basic settings menu to optimize it. as said this menu is not available during playback, gaming etc so it's hard to optimize the quality in real time. Once you do it's much better.

2. Remote is Bluetooth so you cant configure it to other Universal remotes via IR. I purchased the separate STB IR receiver (Rs.199)to help without ...

And one more thing that use mi ir cable with the tv for more comfort it work with my tata sky dth but don't use it for local tv cable network set top box because it is not working with ucn cable network. Overall it is great tv .

Terrible product

Netflix, Amazon Prime Video and several other apps are not available (blocked?)
The LED panel is poorly backlit and the brightest isn’t bright enough. There should be rules against selling such crap! Flipkart isn’t being helpful either and I guess it’s time to quit this online shopping circus!

Value for Money - Big Time!!

Though I have used this product only for a couple of days now, I am highly satisfied. The pictures are crisp and the processor is pretty fast with zero lag. Too good for the price point.

PS: I went with the Flipkart extended warranty since I am unsure of the durability of this new product range from MI.
