Sony Update Firmware: Solve TV 4K 120Hz Enter Fuzzy Problem

Sony's XH90, XH900H, X9100H, XH92 equivalent series of TVs have previously exposed that when 4K 120Hz signal input, the screen will blur. Some users use the Yingda independent graphics card to pass the HDMI 2.1 interface for 4K 120Hz signal input, the picture is significantly blurred than the 4K 60 Hz signal input. In addition, the user has 4K 120 Hz using PS5, and the picture will be seriously blurred. Recently, Sony upgraded V6.0414 firmware for these television, trying to solve these problems. According to the official description, after upgrading the firmware, the user needs to connect to the HDMI 3 or 4 interface if you need to enter a 4K 120Hz signal, and open "enhanced format" in the settings. However, according to Youtube @HDTVTest's raising Vincent Teoh news, Sony this firmware update is not completely solved. From the demo video, this version of the firmware is just a screen sharpening operation for 4K 120Hz signals, which looks clear, although there is some progress than before, but actually does not completely solve the blurred problem. At the same time, this evaluator also said that the Sony PS5 will automatically reduce the image quality and rendering amount of the image when outputting 4K 120Hz screen. Therefore, the player is playing the game when using the PS5 connection 4K TV, the best choice is to set the output refresh rate to 60 Hz. IT House learned that although there are many current TV claims to support 4K 120Hz format, it is perfectly supported only within the machine. Due to the HDMI interface handling chip, firmware, etc., it may not reach this specification. According to the specification, HDMI 2.0 supports 4K 60Hz, HDMI 2.1 should support 4K 144Hz video specifications. However, as the refresh rate increases, the amount of data needs to double, and the bandwidth that needs to be close to 40 Gbit / s can be satisfied. According to some domestic consumers feedback, there is currently no very strict authentication specification for the HDMI 2.1 transmission cable for the HDMI 2.1 transmission cable, resulting in the actual performance of the TV.
