those don't work. HDMI is digital and VGA is analog. No S video on TV available, nor on the computer? Does either have S video?
Or if desktop, add an HDMI card.
I am having many issues trying to hook a VGA output to the HDMI port on a TV. I have tried VGA to HDMI converters from eBay and Best Buy. Going from both a laptop and desktop. It was Computer >> HDMI Adapter >> TV. Never got any display on the television or HDMI Monitor. I know that VGA is analog and HDMI is digital & conversion is needed. Even the Best Buy Geek Squad was stumped. I have seen youtube video's but they never work. FYI: This VGA output is from Windows 7 machines.
