My interest is one way streaming (of a static video graphic image) across a short distance with no signal interference degradation. Just duplicating PC screen's VGA feed ... and wireless VGA sending PC screen image to a near by wireless VGA receiver ... directly interconnected to VGA to HDMI.DVI-D converter ... to feed a 42 inch screen HDMI input. Simple concept but tedious, a little pricy and risky from a many device cascade interaction possibility. “no wires” between these screens is the required objective. Thanks for your input. Back to my early question ... what might the mps or data bandwidth be ... across a typical wireless pathway or will the 42 inch flawlessly display track the smaller local PC screen? Cannot use typical Windows, IT, Net, or Cloud systems. PC is dedicated and running unique industrial control software.
