Ok, I myself connected a cheap Android box to my computer monitor (has 2 hdmi ports). I switch to either hdmi1 (computer) or hdmi2 (android box). I was having problems with former versions of Wyzecam on Android box. Did not try the latest version yet. Tinycam works well though.
Not sure how TinyCam does it. They must have access to the Wyzecam API or something. The Wyzecam itself does not have a built in web interface neither to my knowledge.
I just bought an Android 7 box from Amazon for around 50-60$. I can move that box around and even connect it to my big screen. However, I use it mostly on the same screen where my desktop computer is connected.
I can use most Android playstore apps on that box but I use it mainly to monitor my various cams from TinyCam.
