I tried the Chromecast and it worked but the delay made it unusable. I ordered an adapter but it apparently doesn't work. Can't get the video out to my monitor no matter what I do with the settings. I tried a known good HDMI cable but it still didn't work. Awhile ago I found a gizmo still wrapped up in a plastic bag that looks like a mini-USB to HDMI adapter. Don't know where it came from. I'm wondering what this would be used for. Don't see how I could use it on the Surface because it has a full USB connector. Any ideas?
