Review on 📺 OREI 4K HDMI Splitter - 1x2 Ports, Full UltraHD 4:4:4 HDR, Dolby Vision, HDCP 2.2, 60Hz, EDID Support by Tio Kotaki

To work with ultra wide monitors, you must create your own display resolution profile in the NVIDIA Control Panel. When you have created and tested the profile, quickly switch the splitter to TV mode to successfully complete the test. And all. I use mine to connect the output of an HDMI switch to the input of my ultrawide monitor and audio receiver. Works great so far and much better than video playback from 2 computers but audio from 2nd HDMI cable only on one of the computers. Also, boot errors are easier to spot on the screen and you no longer have to choose between multiple audio output devices in Windows 10.
