Help please: Desktop to tv -vga to hdmi adapter

[krankit]

I'm trying to connect a HP Pavilion a340n to my Sharp Roku TV LC-50LB481U via ONN HDMI to VGA adapter ONA17H0037. The TV detects the HDMI port but won't connect "No signal (is it on?)."

Does anybody have a suggestion or fix? I've tried the troubleshooting steps, unplug, wait, port 1, 2, 3, pick my nose, burp, etc.

Thank you.

Didn't burp enough ? Get Root Beer !
On laptops there's usually a key combination to switch between built in and external display. I also hope that that adapter is active one. Passive one can't do that because it needs to convert analog to digital signal.
