Review on 43" TV Haier 43 Smart TV S1 LED, black by Radko Kapralov ᠌

Revainrating 4 out of 5

The product did not disappoint, the quality pleases.

I think that many people want to know a little more technical details about this TV, and not just a subjective “good picture”. Characteristics: Processors 4x ARM Cortex-A53 @ 1550 MHz (ARMv8-A) Video processor ARM Mali-G52 RAM 1.5GB Internal memory 4GB Bluetooth 4+ Android 11 WiFi supports 5GHz, with a good signal gives 780Mbps The matrix costs * VA (HVA), model CSOT ST4251D02-1 (you can google on ST4251D01-1), It is 60Hz, contrast 4000:1, viewing angle 89, 10 bit, Rec.709 covers completely. It is worth noting that although it is 10 bit, HDMI only works with 8 bits. As for the image display, when you turn on the PC mode, all enhancers are turned off and the picture is very accurate even without calibration, and after calibration it becomes very accurate and close to the reference one (Average ΔE*00 = 0.52; 99% percentile ΔE*00 = 1.51). Before calibration (Average ΔE*00 =22022; 99% percentile ΔE*00 = 5.32), display profile "film", color temperature "warm", enhancers all disabled, PC mode, brightness reduced to ~100cd/m2 default". If you turn off the PC mode (this is how TV shows without an external connection), then even if all enhancers are turned off, it is extremely difficult to set up an accurate display and it is even impossible with high accuracy, because there is some kind of non-switchable LUT that raises the saturation non-linearly in the upper plot. I've only been able to get good results using the service menu settings and HCFR, this method is only suitable for professionals who are well versed in display calibration (and with calibration equipment). HDR mode on TV is more for show, you can watch it, but if the same content is in SDR, then it’s better to watch it in SDR. In HDR, the picture looks like an overexposed frame. I note that when connected to a PC, especially when the game mode is activated, there is no delay. I tried to play APEX, where it is very important - I did not notice any discomfort.

Pros
  • - High contrast, deep blacks - Sufficiently accurate color reproduction in SDR out of the box in PC mode - Can be calibrated to near-reference display colors for SDR in case of HDMI signal source. - There is no image delay with HDMI connection, you can play games where it is critical. - Fast and stable Wi-Fi, you can watch files of any size via torrent - Low price for its characteristics - The sound is normal, but you can also connect headphones, including Bluetooth - Fast video processor, you can watch any video that is decoded by hardware - Steady legs and generally good body quality I would recommend this TV to those 1. Who is on a budget 2. For whom accurate color reproduction is critical, but plans to use mainly an external source (computer or TV set-top box) 3. Has the ability to look at a right angle (feature of all *VA matrices).
Cons
  • - Unswitchable LUT, which spoils the picture when the image is not from an external HDMI connection - No support for non-FAT32 file systems (max file size 4GB) because the manufacturer didn't buy a license from Microsoft. Therefore, you will have to buy in the MLUSB Mounter application - No support for different Bluetooth codecs like AAC, LDAC, apt, etc. (there is only SBC). - The processor is not as fast as we would like, there is not enough RAM, the video will play normally, but it can lag in unoptimized applications. Even in Youtube original when playing in 4K, but in STubeNext there are no such problems (plus more functions and no ads). Similarly, VLC can lag, but only if you turn on subtitles. - HDR mode just for show - No 10 Bit over HDMI __ If you accidentally opened the HKCFactoryAT application, then the only way to fix it is to press the remote control left-right-left-right-up-down or 9731. Keep in mind that after this a hard reset can occur, so it's better not to start it initially. By the way, the service menu can be opened through a pre-installed application. And the additional service menu opens by pressing the main "mic settings".
