I have a TV and a projector that I want to send the same signal to so I can switch between them by moving cables. I have multiple devices in an HDMI switch and then I connect the switch to this splitter. It works with my 4k Apple TV and supports 4k, HDR and 4:2:2. The picture looks indistinguishable with or without this splitter. It has multiple settings for EDID, with a label at the bottom listing what the different modes do, however there is no clear explanation of what the EDID Auto Parse mode or EDID Learn mode does. . I set it to the 2nd setting (4k HDR 2ch Audio) as it most closely matches my setting. The only complaints I have are 1) it doesn't support CEC (so plugging a device behind a splitter doesn't seem to turn on the TV) and 2) it seems to mess up my projector's ARC setting. I haven't determined yet if this is related to this splitter, my projector, TV or switch. All in all I think if you just need to split the signal across multiple devices this works great. If you also want to pass the CEC or ARC, this may not be for you.
