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

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.
