It seems like the monitor may have an issue. There is nothing else in your signal chain (like a HDMI splitter or switch, cheap ones can be bad at passing EDID), so EDID is not being blocked there. So it doesn't seem like an issue with the cable or GPU. Your other ViewSonic can be plugged in and recognized. It sounds like your HDMI 1 port is broke? Maybe the EDID ROM in the monitor failed as well. 1024x768 it is!ĮDID is basically on a small memory chip and set by the manufacturer. Well better pick the resolution I know monitors have supported forever. What resolution should I send it? I have to make sure the person can see some information, otherwise they may not be able to use me. In cases like this I call it a Generic PnP Monitor. PC: Ok well I know something is plugged in, but I don't know what it is. Now, with an EDID error something goes wrong, so instead we get: I see your preferred resolution is I will do that." (This timing list is what the PC uses to populate the list in the Displays control panel)
I support these resolutions:Ģ560x1440 at 60hz, 50hz, 30hz. PC: "Hey, I see you are a monitor, what monitor are you?" Usually its an EDID error somewhere in the chain, or the monitor itself.ĮDID is the information a monitor sends to the PC with information about itself.
VIEWSONIC DRIVERS MONITOR WAS NOT FOUND DRIVER
In my experience "Generic PnP Monitor" is not a driver issue.
