A good budget 4K HDR TV


The 43-inch screen size is the only one in India where you can choose between a 4K TV and an FHD TV. More than the resolution, the display of content in HDR versus SDR is more important. While a 4K image looks sharper than 1080p, using HDR on budget TVs is disappointing and sometimes the SDR image looks better than the HDR.

Today we have with us the Redmi Smart TV X43. It is a 43-inch addition to the Redmi Smart TV X series that is now available in 43, 50, 55 and 65-inch screen sizes. We have reviewed the 65-inch Redmi Smart TV X65 and thought it was decent value for money. In the 43 inch space we have: reviewed the Redmi FHD which is currently priced at Rs 24,999. We also have rated offers from Realme also. As of the writing of this review, the Redmi Smart TV X43 costs Rs 28,999 and comes with all the features of its bigger siblings, including support for Dolby Vision and HDR. Is it a worthy consideration over the FHD Redmi Smart TV 43?

Redmi Smart TV X43 Display Panel and Picture Quality

The Redmi Smart TV X43 has D-LED backlighting. As for the peak brightness, we’ve included a peak brightness of 372 nits in the Vivid preset, but in the Movie and Standard preset you can expect a peak brightness between 250 and 300 nits, which is low for HDR content. Whether this hinders your viewing experience, however, we’ll discuss below. What impressed the device was the Colorchecker analysis, which yielded an average delta error of 2.9, which is quite good. Even in the grayscale 2pt, the error was less than 2, indicating good performance overall. In the saturation ranges, we have an average delta error of 2.5, which is very good, indicating a good rendering of colors in general. So while the TV’s brightness may be low for consuming HDR content, it has pretty good color reproduction.

As we mentioned above, the TV’s peak brightness is nothing to write home about. But that’s not the biggest problem with budget HDR TVs. It’s that the dark sequences should not look too dark and the colors should look good. That’s exactly what we found here. On a show like Our Planet (available in Dolby Vision on Netflix), we didn’t get the specular highlights like we did on other TVs with higher peak brightness, but the darker parts of this show were still quite enjoyable. The same goes for a show like the Grand Tour (available in HDR 10+ on Prime Video). A stark highlight has to be the dark sequence we use in Jack Rayan, another HDR 10+ show on Prime Video. The order we use for testing has a slightly darker tone on budget HDR TVs, but that wasn’t the case here. It was fresh and easily enjoyable.

HDR 10+ on Redmi Smart TV X43

There are some instances where the content on the screen looked a little darker than expected, but these moments were few and far between. The Dark Knight Rises is a prime example of this, with most of the action in the first two-thirds of the film taking place at night. While many of these dark sequences were easy to watch, there was some loss of detail due to the TV’s low peak brightness. But this is an example as with other pieces of content with dark sequences, albeit Modified Carbonthe content was easily enjoyable.

Redmi Smart TV X43 supports Dolby Vision.

The TV comes with many settings, giving you quite a bit of control. For Dolby Vision content there is Dolby Vision Bright and Dolby Vision dark and as always, keep the TV in Dolby Vision Bright regardless of the lighting in the room. HDR 10+ has only one option, while HDR 10 content has HDR Standard, HDR Vivid and HDR Movie. Here I found that HDR 10 Movie worked best for almost all HDR content.

A new addition to Netflix recently was Spider-Man Far From Home. This title is available in 4K but in SDR. The details on Spider-Man’s suit are quite detailed, with the red and blue hues popping out. The fight with Mysterio, which starts at 1 hour and 15 minutes and ends with Spider-Man being hit by a train, is a great example of SDR rendering with a healthy mix of colors and bright and dark sequences. The TV can reproduce these sequences well and with a little bit of biased light in the room there are almost no halo or bloom effects on the screen. Overall performance is very good for SDR.

Ordinary SDR content, be it from a set-top box or even streaming services, looks good on this TV. For watching movies and most TV shows, I recommend using the Movie preset. However, as we’ve seen on other TVs, we found that some shows, like Young Sheldon, look best with the default preset, despite the slightly cooler color preference. The only thing I recommend is going into the settings and turning off motion smoothing as I’m someone who doesn’t like the artificial smoothing effect in movies. That’s a personal choice, as you may like it.

Redmi Smart TV X43 Gaming Performance

Gaming on this TV is generally good, although we had the same problem as other budget HDR TVs. When using a PS5 (rating) to the TV for the first time, you will be prompted to calibrate the brightness. Dirty firing 5 (rating) after calibration and you immediately realize that the TV is trying to push way above its weight. Since Dirt 5 is a HGiG (HDR Gaming Interest Group) game, it relies on the brightness calibration between the TV and console. You have to go to the settings of the game and adjust the brightness so that the content does not look burnt. Other games like Ghost of Tsushima (rating) and Spider-Man: Miles Morales (rating) and more look like they did on the Redmi Smart TV X65 we reviewed – generally good with the loss of some detail acceptable at this price.

Redmi Smart TV X43 Audio Performance

Loud is the first thing that comes to mind when you hear the sound from this TV. It can get quite loud and fill a small room with ease. While there are a ton of audio presets to choose from, I found that leaving the TV on Standard or Movie based on the content gave the best results. The audio does lose clarity at high volumes and I found that going beyond 20-25 was just too shrill, especially for movies. Below 25, the volume is clear and audible with clear dialogues in TV shows. But to enjoy a good movie, you have to invest in a soundbar.

Redmi Smart TV X43: User Interface

Xiaomi still offers the best of both worlds: PatchWall and Android TV. The Android TV UI has undergone some minor changes, making it more in line with the Google TV UI. It has a Discover tab that shows a collection of content from OTT apps. The home screen offers a mix of content from OTT and your app library. It is an evolution of the Android TV UI to bring it more in line with the new Google TV UI. You also get PatchWall, which has a better content-first approach and is the same we saw on the Redmi 43-inch FHD TV, Mi QLED TV 75 (rating) and even the 65-inch Redmi TV. It has the same content curation with space for lists like IMDB top 100 list and more lists like HDR 10+ content, Dolby Vision content, etc.

Redmi Smart TV X43 Remote Control

What has changed for the better is the remote control that comes with the Redmi Smart TV X43. While it still doesn’t have a dedicated mute button, you get a new dedicated Disney+ Hotstar button and a dedicated button to pull up the app drawer. The rest of the remote’s design and ergonomics remain the same with a dedicated voice assistant button, D-pad, back button, and dedicated buttons to access the PatchWall and Android TV UI.

Redmi Smart TV X43: build and design

The build and design of the Redmi Smart TV X43 is almost identical to the Redmi 43-inch FHD TV we discussed earlier, with the exception of a few points here and there that you wouldn’t notice if you didn’t know what you were looking for. . † The TV has relatively thin bezels all around considering the price and the TV is held in place by 2 simple plastic feet.

For connectivity, we have 3 HDMI ports, 2 USB ports, an optical port, a 3.5mm port, AV input and an ethernet port, along with an antenna port. There’s also Bluetooth 5.0 and dual-band Wi-Fi, which is nice. Overall, it’s a plain looking TV and that’s okay considering you’ll be spending more time on the decent performance screen.

Bottom Line

What the Redmi Smart TV X43 has to offer are the same features that made its bigger siblings a compelling offering. The TV is packed with features, including support for almost all HDR formats, a wide range of connectivity options and a simple design. Construction is similar to other budget TVs we tested. The TV’s panel has very good color reproduction for HDR and SDR, but the peak brightness is lower than what we’d want for an immersive HDR experience. The audio output is average. Considering the price of 29K, this is a good option for those looking for a budget 4K 43-inch TV.
