48Gbps HDMI 2.1 inputs Posted on August 6, 2022 By Phil Jones LnRiLWhlYWRpbmcuaGFzLWJhY2tncm91bmR7cGFkZGluZzowfQ==IEBtZWRpYSBvbmx5IHNjcmVlbiBhbmQgKG1heC13aWR0aDogNzgxcHgpIHsgICB9IEBtZWRpYSBvbmx5IHNjcmVlbiBhbmQgKG1heC13aWR0aDogNTk5cHgpIHsgICB9IA== Support for 4K@120fps HIgher-end Epson projectors like the Pro Cinema LS12000 and Home Cinema LS11000 include two 48Gbps HDMI 2.1 inputs to accept 4K@120fps signals. We should note that while the inputs can support up to 48Gbps, the HDMI inputs/outputs found on most A/V Receivers, video switchers, and gaming consoles are limited to 40Gbps. This is fine because the video information in a 48 Gbps signal far exceeds the capabilities of the 10-bit panels/imaging devices found in consumer TVs and projectors. 48Gbps HDMI 2.1 inputs support 4K HDR at 120 frames per second Currently, there isn’t a lot of 8K or high frame rate video content available, but 4K@120fps can help deliver a smooth, high-quality gaming experience from a high-end gaming PC as well as the latest PlayStation and Xbox gaming consoles. Also, when gaming 4K@120fps, input lag time is below 20 ms. eARC (Enhanced Audio Return Channel) In addition, if you decide to connect a game system directly to the projector, one of the projector’s HDMI inputs supports ARC (Audio Return Channel) and eARC (Enhanced Audio Return Channel). The HDMI input that supportseARC/ARC is clearly labelled While HDMI ARC (Audio Return Channel) format supports multi-channel audio, which includes Dolby Atmos, due to bandwidth limitations, it delivers a compressed audio signal, for example, Dolby Digital Plus. The latest version of HDMI audio return is eARC (Enhanced Audio Return Channel). which can transfer a much higher bandwidth, and it also supports uncompressed audio surround formats like Dolby TrueHD and DTS Master Audio. This ensures the external audio system receives the maximum quality audio signal from a source that is directly connected to the projector.
