![]() ![]() ![]() Part of the MPEG Noise Reduction process. Generally not needed for high quality content unless there are some banding artifacts. Useful mostly for poorly compressed sources that may benefit from the simultaneous application of the noise reduction and smooth gradation filters. This process comprises noise reduction and smooth gradation filters, with each filter being applied only once in the B8 (so the entire process is dual-step), and twice in the C8 (hence the quad-step process). Google Assistant is available in more countries), reduces the time cursor stays on screen when the Magic remote is not used, and provides fixes for various bugs. Despite the version number and timing differences, the latest firmware for either the LG C8 or B8 adds the same functionality (e.g. The firmware updates for LG C8 are released alongside those for LG W8, E8 OLED TVs since they also have the Alpha 9 processor. For example, the latest version is 04.10.05, and it was released on October 5, 2018. When it comes to the LG C8, though, it has a different processor (Alpha 9), so the timing is different. The latest version is 04.10.06, and was released on September 14, 2018. The firmware updates for LG B8 are released at the same time as those for the LG SK9500, SK9000, SK8070, SK8000 LCD TVs (since they have the same Alpha 7 processor). The CPU and GPU improvements are important for image processing, real-time analysis of video signal in particular, and determine how complex picture enhancements the B8 and C8 are able to perform. Memory performance is improved by up to 50% on TVs with Alpha 9 vs Alpha 7. Up to 35% increase in CPU & GPU performance on Alpha 9 in comparison to Alpha 7. There is some distinction in the HDR peak brightness on the LG B8 vs C8 in low-APL (Average Picture Level) scenes during which specular highlights can be rendered slightly brighter by the LG C8 vs B8. Differences on the LG B8 vs C8 not related to video processing are design of the table top stand and screen sizes they can be found in. Out-of-the-box color accuracy is also distinct on the LG B8 vs C8 (due to the different number of color data points in the internal 3D cube look-up tables the two OLED TVs have), and so are HFR (High Frame Rate) capabilities (but only when the 4K signal includes HDR). There is one exception, though, and it concerns content with in-source posterization artifacts in which case the LG C8, due to the second pass of decontouring filters, is more effective in providing smooth gradation than the LG B8 which relies on a single-pass banding removal. That being said, the impact of these features on the picture quality is limited (and they can be discarded altogether when watching high quality sources). Due to a different image processor being used on LG B8 vs C8, the number of steps in the MPEG Noise Reduction process is different, and so are the depth and sharpness enhancer techniques on the LG B8 vs C8. The main LG B8 vs C8 difference is their video processing capability. ![]()
