Is the convertor is one of the bum models. Try another.
The other issue is the display is neither 720p or 1080p but 1050 lines. It's likely the convertor can't do this conversion.
So I had just recently purchased a hdmi to vga converter/adapter cord. And it have everything plugged in right and I'm getting "Input Not Supported". Any way to fix this. I'm a little good with electronics but I'm not amazing so bear with me. The monitor info is:
Model no. : P221W
Version : P221W d
Mfg date: jul 03, 2007
Part number: ET.EP1WP.001
Reg. Type: ADAW
if anything else is need I can set up my desktop again and give what ever info is needed. Thanks
