Mi tv Notable improvements, but some old quirks

Xiaomi launched its new Mi TV 4X (Review) series of Ultra HD Smart TVs recently. This is the first set of TVs from the company to officially support Netflix and Prime Video.

This series also brings 4K panels to Xiaomi TVs with screen sizes smaller than 55 inches. We got the 50-inch variant for review.

Mi TV 4X 50 has a standard design. Though it doesn’t remotely look bad, there is no wow factor either. It sticks to the standard design language seen on the 4A Pro and 4X Pro. The bezels are fairly narrow and the TV isn’t too bulky, but the build quality feels a lot better as compared to the 4A Pro.

The company has opted for glossy bezels here instead of the matte borders seen on the Mi TV 4A Pro. The bottom bezel bears the company logo and features a small chin underneath that hosts a power LED and a hidden power button.

The Mi TV 4X 50 has a 50-inch Ultra HD (4K) panel with a resolution of 3840 x 2160 pixels. As is typical of Xiaomi, the panel type isn’t mentioned, but our review unit seems to have a VA panel. The company does specify that it’s a 10-bit panel capable of displaying up to 1.07 billion colors.

That is a massive upgrade over the 8-bit 1080p (Full HD) panel found on the Mi TV 4A Pro 49. However, the response time seems to have taken a massive hit. It has gone up from 6.5 ms to 9.5 ms, making it the slowest of all their panels thus far.

The Mi TV 4X 50 is powered by a 64-bit Amlogic CPU with four Cortex A53 cores, Mali-450 MP3 GPU, and has 2 GB of RAM and 8 GB of internal storage, a chunk of which is taken up by the OS. The specs are decent enough and there was no noticeable lag in the UI during testing.

Since this is an official Android TV, it has Chromecast built-in that lets you cast videos from supported apps like YouTube, Hotstar, etc. A new addition here is the long-awaited support for Netflix as well as Amazon Prime Video. Both apps are preloaded on this TV. A pair of stereo speakers deliver 20 W RMS audio output.

You get a decent spread of connectivity options comprising three HDMI ports, two USB ports, one RJ45 LAN port, one A/V in and an SPDIF out. One of the HDMI ports also supports ARC (Audio Return Channel).

Like most Xiaomi TVs larger than 43 inches, there is no optical audio out here or any analog audio out options like a coaxial A/V out or a 3.5 mm headphone jack. So, you cannot use any standard speaker with the Mi TV 4X 50.

You need to find one with either SPDIF or HDMI ARC input. However, wireless Bluetooth speakers or headphones can be used with this TV as it supports Bluetooth 4.2. The TV supports dual-band Wi-Fi and can connect to 2.4 GHz as well as 5 GHz Wi-Fi networks.
