I’m surprised I couldn’t yet find a dummy HDMI plug to spoof a 4K@120Hz capable display. All the ones I’ve found thus far only support 120Hz at 1080p, and never any HDR support at all. I have an OLED android device with 2K screen and matching refresh rate, but the without a physical monitor to stream capturing from. Emulating such display resolutions and colored depths also seems just as formidably challenging.
