So far, these have failed. Try other models?
And in the future don't leave out details like the monitor make and model. Some have VGA and I've seen PS3 to VGA work fine. PS2? http://www.amazon.com/HDV-G300-HDMI-Converter-Scaler-1080P/dp/B0093JQM56 seems to be hit or miss. All folk call it a PITA to setup.
So for some reason I can't get my PS2 or my Gamecube to connect to my monitor. I bought a composite to HDMI converter and when I plug it in there is no video. If I plug in the Red and White audio into a speaker system I get sound but never video. The set up is PS2 to converter then the converter to a HDMI to DVI cable, then to my monitor. Can anyone help?
