Review on 💡 SIIG 4K@60Hz HDR HDMI Splitter with EDID Control, YUV 4:4:4 8-bit, YUV 4:2:0 10-bit, HDMI 2.0, HDCP 2.2, 18Gbps, Auto Scaling, Low Heat, Cascadable, Firmware Upgradable - 4 Port, 1 Input 4 Output by Josh Reynolds

Before that, I tried two more. Others have sync and HDCP issues and get very hot. This one was solid from the start. By default edid is set to 4k 60 HDR 7.1 audio and it worked great. However, if you want to switch framerate based on content, you need to set Edid learning mode so that it can adjust Edid based on your environment. I've only had it for a few days, but I haven't had any problems. The block heats up, but does not heat up. I'll update if anything changes, but so far I'm very happy with it. I'm using it with the ROKU Ultra source code. 29/30/60 (mostly going through everything). I also find that the learned edid is lost when the device is switched off and I had to learn it again. With the default setting of 111, my Roku didn't switch to 24Hz to play movies. I think most displays that can accept 4k 60 can display 4k 24, and would it be better (at least for North America) to support 24 and 60 on first edid?
