So I plugged a VGA to DVI adapter into the computer's VGA port, plugged the DVI cable to my antique monitor into that and powered everything up. The monitor claims it isn't getting a signal. Now, if I disconnect it, it says "cable not connected," so obviously the connection is good. The monitor works with other computers, so that's not it.I'm going to blow another five bucks and try a DisplayPort to DVI adapter. I suspect that the problem is that the refurbisher installed Windows 10 on a computer that was designed for Win95--it's going to get wiped and have Linux installed, but to do that I need a working video port.Great price point, but for now this is more a puzzle/project than a usable computer. I'll update when I've tried the DisplayPort output.
