Hi, I would like to ask if this will work, I intend to get a dummy HDMI display so that I can try out the hdmi-in demo. I know it worked with a monitor, because I tried it, however my usecase for it, is to use it without a working screen. So anyone know if is possible?

@WongTX are you are referring to the HDMI dummy that is typically used for spoofing the presence of an HDMI monitor ?

You want to connect this to a HDMI-IN port ?

@Electr1 Hi, Yes I am referring to that. But I will be using it for the HDMI Out, not HDMI In. According to the docs, it requires a working HDMI Screen for the HDMI IN to work. So I was wondering if it will work, cause I wont be carrying around a screen around with me.

@WongTX Yes it should work.

@Electr1 Thank you very much!

Not all dummies will work, You need one that matches the resolution you want to capture - I went though several until I found one that did 1080p only

Oh no, I already bought the one with 4K, does the FPS matter also? Thank you for the information!
