But, with a few problems of its own.

Xiaomi is one of those companies that has built its entire fanbase thanks to its aggressive pricing strategies. And just a couple of months ago, Xiaomi entered the TV market here in Nepal by launching two TVs. While saying this move blew the competitors out of the water is a blatant exaggeration, I can say that Xiaomi’s presence in the domestic TV industry was a surprise to be sure, but a welcome one. We were quite eager to test, review the Xiaomi Mi TV 4X 55 in particular, so we got one for ourselves.

Retailing at Rs. 65,000, it is an intriguing offering (to say the least). After having used it for about 2 months now, I can safely say that this is a banger of a TV, at least considering other options in the local market. So, allow me to discuss the Xiaomi Mi TV 4X 55 at length in this review.

Xiaomi Mi TV 4X 55 Review:

Design & Build

  • A plastic back panel, minimal bezels upfront
  • Can be wall-mounted or installed using a stand

As always, let’s start with the design & build quality. Like it is with every other TVs these days, the Mi TV 4X bears a striking resemblance to any one of them out there—with its minimal bezels and the standard black color finish. The back panel has been made from some sort of plastic material while Xiaomi has given a coarse touch to the entirety of the panel too.

Similarly, the bezels on the front have this sort-of matte finish to them, while the chin houses a small “Mi” branding. And just below it, you’ll find the LED power indicator. Underneath it, there’s a dedicated power button as well, which is self-explanatory. The Mi TV 4X 55 can be either wall-mounted or installed using a stand. We went the second route as it offers a greater level of flexibility for our inconsistent office layout.

Weighing just 13 kg, the TV is relatively easy to carry around from one room to another. There is a little bit of wobble to it, but nothing to be alarmed by. Looking at the back of the TV, one can find a separate module that houses the I/O ports. Unlike the supposedly premium TVs from other manufacturers like LG, Samsung, Sony, etc. this one does not have a cable management mechanism. So, installing a bunch of wired components may disturb the room’s aesthetics if not handled well.


  • 55″ 4K UHD LED-backlit LCD display
  • HDR content compatible
  • 60Hz refresh rate, 178º viewing angle

Moving on, as I mentioned earlier, this is a 55” 4K UHD TV which has an LED-backlit LCD display. Unfortunately, Xiaomi hasn’t specified the type/grading of the panel used and I couldn’t find any binding detail about it on the web either. Android Authority does mention that the TV comes with an IPS panel but hasn’t provided any source to the claim, nor has it elaborated on it in any way. Furthermore, during the review, the display of Xiaomi Mi TV 4X 55 seemed to reveal characteristics that side with a VA panel instead.

For instance, its viewing angle isn’t that good—a trait common in VA panels. Although the official product page specifies a 178-degree viewing angle, the reality is far worse. Unless you’re sitting straight ahead of the TV, there’s a noticeable drop in brightness and saturation level. It’s almost bizarrely bad. Like, I would move a couple of changes to the side and the viewing angle would suffer.

So, if you’re planning on installing this TV in your living room where you’d want to enjoy it alongside your friends & family, disappointment awaits. Likewise, the display is quite glossy and reflective too. To counter this, I had to put on opaque drapes so that it would stop reflecting light all that well. This could easily be prevented by setting the TV in a fairly dark room. But it’s reasonable to say that that’s not possible in every household.

Xiaomi Mi TV 4X 55 - Display

Anyway, talking about the quality of the core panel itself, it’s pretty good—although I’m slightly leaning towards the one on CG55A1 that I reviewed a while back. The colors, contrast are excellent and it supports HDR format as well.

HDR, overdone?

The spec-sheet of the Mi TV 4X 55 further specifies 10-bit color depth and Vivid Picture Engine for enhanced color reproduction and a boosted brightness level. All sounds good till now but at times, I felt like this algorithm along with other internal image processing is a little too aggressive to my liking.

I watched the second episode of Netflix’s The Umbrella Academy’s season 2 and dear heavens—the contrast level is almost an overkill on this TV. In the scene where Allison goes to the police station (timestamp – 18:03), I almost couldn’t make what’s happening on the screen. It is a fairly well-lit scene but still, the HDR algorithm just—spikes up the black levels too much, and subjects sometimes tend to look over-sharpened as well.

Everything looked perfectly fine when playing a few HDR test videos from YouTube, though. I mean, it has a rich contrast and the black uniformity is pretty impressive. But on other dynamic content, the story was a little different. I also tried playing the hallway fight scene from Daredevil season 1 and here, although things weren’t as bad as the previous instance, the overall experience was slightly underwhelming. The yellow and red levels are slightly off the charts but still enjoyable.

Moreover, the Mi TV 4X 55 is equipped with the standard 60Hz refresh rate and Xiaomi hasn’t bothered with any form of motion smoothing feature. While this is an inherently unnecessary thing to have in regular content, it does have some significant uses. In fast-paced programs like live-action sports, events, etc. this feature elevates the TV-viewing experience to new heights. But, this “soap opera effect” is dreaded to have activated on standard TV programs, movies, etc. Maybe that’s where Xiaomi’s priorities were—I don’t know.

Fast-paced content

Regardless, watching sports channels was a bag of mixed feelings. In certain cases, the gameplay looks all right with no image retention, or other issues of any kind. Perhaps the signal broadcaster itself is applying some sort of frame interpolation algorithm—I’m not sure. But in most cases, the content looks choppy and jittery. And when watching a couple of boxing games, I could even notice the ghosting effect.

Xiaomi Mi TV 4X 55 - Bezels

Besides these, I didn’t face any problem regarding brightness, sharpness, and other factors with Mi TV 4X 55’s display. When viewing the TV from approximately 2 meters away, I couldn’t notice pixelation and the content on the display looks crystal clear. There is not much to mess around with the display settings.

You can play around with the color temperature, backlight level, picture mode, etc. but, the default settings worked just fine for my eyes. One interesting feature I noticed is called “Dynamic Backlighting”. What it basically does is adjust the panel’s backlight level depending on the content playing. I did find that turning this on enhanced the viewing experience when watching comparatively under-lit content.


  • 2x10W speakers (bottom-firing)
  • Dolby Audio, DTS-HD compatible

In terms of the audio, the Mi TV 4X 55 has two speakers with 10W output each. These down-firing speakers also support Dolby Audio and DTS-HD. The speaker gets plenty loud and can rock an average-sized room of about 200-300 square feet without breaking a sweat. Vocals sound crisp and clear whereas there are a fair bit of details in the high frequency as well. However, its low-frequency reproduction like the bass is almost dismissable and is rather overblown by the mids most of the time.

This one doesn’t have 360-degree audio either so immersive sound quality is out of the question. But, that’s a perfectly excusable exclusion considering the price of the thing. The audio gets slightly distorted when cranking up the volume to the max so be advised against that as well. Overall, the audio on this TV is not that bad. But if you have a trained set of ears and want immersive sound quality, you’re better off installing an external soundbar or a home theater system.


  • A healthy selection of I/O ports
  • Dual-band WiFi, Bluetooth 4.2

Getting to the connectivity front, the Mi TV 4X 55 has a healthy selection of ports. You get 3x HDMI, 2x USB 2.0, and an antenna socket on the right edge. Similarly, there’s 1x ethernet (RJ45), 1x S/PDIF, and an AV input connection on the side. Among the available 3 HDMI ports, 1 of them also supports ARC (Audio Return Channel) protocol. Using this, you can connect the TV with your ARC-compatible AV receiver or soundbar.

Similarly, the wireless options on the TV include Bluetooth 4.2 and dual-band WiFi. Here, you’ll definitely want to use a LAN cable for a relatively buffer-free 4K streaming. During the test, I found that even when connected to a 5GHz network, the TV would buffer significantly more sometimes—a problem almost eliminated with a stable wired connection. In addition, you can also connect your thumb drive to view pictures, play audio files, or watch movies.


  • Android TV 9.0 with PatchWall
  • Google Assistant-enabled
  • Chromecast built-in

On the software side of things, Mi TV 4X 55 is an Android TV running on version 9.0 (Pie). With this, you can easily download all your favorite apps from the Play Store. The interface is clean and extremely user friendly. But, we’ve received news that this TV won’t be getting any software update. Now that’s a major bummer because I really think the Mi TV 4X 55 could use some software optimization for better performance.

Powering the device is a quad-core Amlogic processor, with 2GB of RAM and 8GB of internal storage. First off, the entire UI feels slightly off, laggy sometimes. Moreover, its cold boot can take up to 30 seconds. This TV also supports Google Assistant voice control, but that too is far from ideal. I don’t understand why but it just gets unresponsive sometimes while working fine the other times. It’s weird to say that occasionally, even the speech recognition takes a hit. You’re requesting one thing, and the assistant processes something different altogether.

You get a “Try Saying” suggestion prompt on the TV as soon as you press the assistant button on the remote. Still, it doesn’t take your requests just then and there but rather proceeds to process the end portions of your command. The apparent trick is to wait a couple of seconds before the UI layout of the TV gets subdued indicating that the assistant can now take your requests. You can also open the TV’s settings, open apps by requesting Google Assistant. Yet, this is hit-or-miss as well.


Further disappointment comes from Xiaomi’s content-recommendation system PatchWall—in that it doesn’t work in Nepal. I tried changing the TV’s region to India. With this, the Mi TV 4X 55 would load up the PatchWall UI in its entirety but would refuse to play most of the content. At first, most of the recommended movies, shows, documentaries belonged either to Disney+ Hotstar, or Amazon Prime Video—while still holding a separate tab for Netflix, YouTube, and such. Videos from Netflix, YouTube played fine (as it directed to their respective app) but on other streaming services, I would get an error message.

So, to rid of this half-baked experience, I switched the TV’s region back to “Other”. Once again, I checked to see if something would be different this time around when setting the region to India. Surprisingly, it did. Now, it wouldn’t even load up the PatchWall UI that it did before.


Besides all these, the Mi TV 4X 55 also has Chromecast built-in. With this, you can easily stream content from your phone to the TV. This feature worked perfectly without any hiccup. If you are on a metered connection (volume-based internet plan), the Data Saver feature is something you’d really want as well. Turning this on intelligently adjusts the streaming quality to use as little data as possible. Xiaomi claims a 3x drop in bandwidth consumption but it was hard to test it out; given how vague of an assertion that is.

Likewise, Mi Nepal’s product page for the TV 4X 55 mentions that it supports H.264 (AVC) video decoder, and not H.265 (HEVC). This could very easily be a typo on their end when looking at other sources like Mi India. And, disabling a video decoder feels based on region sounds like an implausible thing to do. Now, the reason I’m talking about it is that H.265 offers better bandwidth saving compared to H.264. All the popular streaming services like YouTube, Netflix, Amazon Prime Video, etc. already support this codec. Therefore, you can stream high-quality content from such sources with minimum data.


  • Mi Remote’s design is pretty sleek
  • Could’ve used a couple more buttons

Xiaomi Mi TV 4X 55 - Remote

On to the remote, the Mi TV 4X 55 gets a small, minimalistic Mi Remote. With a subtle matte finish, this remote is incredibly lightweight and easy to use. The buttons feel plasticky, but I got used to it in a matter of days. While the design, build quality are praiseworthy, the button choice could’ve been a little more extensive. The lack of dedicated settings, mute, YouTube button resulted in quite a bit of hassle during my usage. Going through a bunch of hoops to activate such seemingly simple features is an uninspiring journey.


In conclusion, the Mi TV 4X 55 is a great value-for-money TV in Nepal. Getting a 55” 4K HDR TV of this quality for under 70K is a significant achievement for the domestic TV market. With its 1 year of product and an additional 1 year of warranty on panel, this TV is a superb TV for the average Nepali household.

Admittedly, it is far from perfect and doesn’t compare to similar offerings from other established brands. If you already have a taste for premium TVs, this one is not for you. But for those specifically looking for a premium TV experience on a budget, it is an excellent contender for your money. Some might even argue that a couple of complaints I made about the Xiaomi Mi TV 4X 55 throughout the review are negligible considering the overall value offered by the TV.

Value for Money
mi-tv-4x-55-reviewIf you want a big TV watching experience, but don't have the best dollars, the Mi TV 4X 55 is almost a no brainer. For casual TV viewers, what Xiaomi has been able to deliver at this price point is truly remarkable. Having said that, it does have some limitations that might come into play if you've developed (or are looking to develop) a sophisticated TV lifestyle.
