I was looking at that first one you sent me to on Amazon and it says:
"Not Bidirectional: Only from HDMI to VGA, NOT VGA to HDMI; easily connect HDMI devices with VGA compatible monitor"
So, my computer has a VGA port. My monitor/TV is HDMI. My monitor/TV has a VGA port but we only get a blue screen on the monitor so we think that the VGA port on the TV is not working and that's why we need to connect it with a HDMI.
Why is this so hard?
