AOC LM520A Monitor "Input Not supported" with VGA-HDMI converter

[Theo Brown]

Using a raspberry pi with this adapter (http://www.amazon.co.uk/gp/product/B0088K7QUQ/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1)- people have used this adapter fine with their rpis previously. I can use the converter with any of my other pc monitors fine.

When I boot up my pi the monitor displays the error message "input not supported" despite me having changed the settings to 1024x768 @ 75Hz which is supported by this monitor. Any ideas why?

And the adapter descriptions says: Support HDCP 1.0 / 1.1 / 1.2 / 1.3, HDMI Input: 480i / 576i / 480p / 576p / 720p / 1080p, VGA Output: 480i / 576i / 480p / 576p / 720p / 1080p. I don't see 1024p.

What is 1024p? Is that 1024x768 @75Hz? I don't really understand.
