    Sounds like the adapter quit to me.

    I just bought a new cord for the screen. This time I bought a cord with VGA at one end and HDMI at the other, rather that use the cord that came with the computer and use an adapter. It still does not work.

    I'm not sure what to check next. As I was plugging it in this morning I remembered an issue that arose a few days before it stopped working. I log into a remote server and use that server on one screen and I use Windows on the other. Before the screen stopped working I started getting an error message (through the server I was logged into, not through my regular desktop) that had to do with C++ installing updates. But it never completed the task. Again, that was through the remote desktop server, not through my own desktop, and the remote desktop has nothing to do with my screen setups.

    Do you have a web link to that cord? If it's just a "cord" with no electronics, I can't see how it could work? VGA is an analog signal and HDMI does not supply an analog signal. DVI does but HDMI doesn't, not as far as I know anyway. It's digital only.

    The adapter I used worked just fine for months. It must have whatever it needs to transfer the signal from analog to digital.

    Update: Online chat help yesterday with Dell remote connected to my computer and removed all the graphics drivers, reinstalled and updated the Bios. Did not work. They informed me it has to be a hardware issue and that the HDMI port is faulty.

    Today the field technician came out and replaced the board and it still did not work. Tells me it has to be a software issue.

    I call Dell after he leaves and they try telling me it's the monitor (even though both work separately through VGA). Then they tell me they don't know what it is and I have to reinstall Windows 8.

    I've never had issues with Dell customer service before, but these guys are starting to annoy me. The one on the phone was arguing with me and asking me three times how old the monitors are (even though I told him after the first time that I do not know as they were here before I started).

    Not sure where to go from here.

    Ok, but you said "I just bought a new cord for the screen. This time I bought a cord with VGA at one end and HDMI at the other, rather that use the cord that came with the computer and use an adapter. It still does not work." I read that to mean the new cord replaces the adapter that used to work but doesn't now? That's why I asked for a link

    Hey Gormy,
    I imagine you've already looked at this, but what does it say in the "Multiple Displays" field in the Screen Resolution control panel? With both monitors plugged in, right click on your desktop and select "Screen Resolution". It should be set to "Extend these displays".

    There is also a little utility you could try called HdmiYo ver 0.1.1.

    I have been running it for a few years due to occasional connectivity issues with an HDMI connection on my Win7 machine, and this has worked well to force the handshake. I don't know how it will work with Win8. This is the only place I can find to download it:

    https://onedrive.live.com/?cid=bd288...2B18AC2B0C!143

    After installation, press Ctrl-Space to force handshake.

    I think that's all I've got!

    Thanks for the tips drteeth. I have tried extending the displays. Here's a few more steps I've tried. I went back to my adapter and read somewhere to always plug the HDMI end in first before plugging in the VGA end on the monitor. I did that, and it now detects the second monitor again. It shows up as the second one, has the monitor model number in the drop down box in the Screen Resolution box, and allows me to extend the displays. I can run the mouse off the main screen onto the second screen, however, there is no display. It is stuck in power save mode. If I swap the monitor VGA cords, the second one works and the main one does not. So I know it's not a monitor issue. I also tried downloading your utility and pushing Ctrl-Space. The main screen blanks out for a second and turns back on, but nothing with the second screen.

    So that's where I'm at now. Second monitor detecting but not displaying. Stuck in power save mode.

    Just updated the drivers again and restarted. That did not help.
