Monitors worked yesterday, today they dont.

[ltylert1996]

So im a day trader and I run 2 external monitors along with my laptops built in screen. I have one monitor connected with hdmi, and one uses a USB to vga adapter. Ive used this for nearly 8 months and had no issues. It was fine yesterday when I turned it off. This morning, both monitors wont work at the same time. If the monitor connected via usb adapter is on and I unplug it, the hdmi monitor will come on, and vice versa, but they wont both work at the same time. Can anyone help me figure out what changed overnight? I already tried updating the drivers for the usb adapter and that didnt fix it.

What operating system are you using? What does your Windows display configuration indicate? Does it see both external monitors?

Windows 10. And no, it only sees whichever is working at the time.

Check your Windows update history and see if there is anything recent. If so, remove that download and reinstall your drivers.

Okay I will. And I only made the duplicate thread because I got an email a few minutes ago saying this thread was removed, but apparently it wasnt.

When you created this thread, you likely double clicked the submit button. This created two identical threads. I removed the other one (which prompted the e-mail). You should have received yet another e-mail which also stated the thread was deleted (the "replacement" thread you just created).

Ah okay. Sorry about that. The only update since it last worked was "Definition update for windows defender" which shows it has updated almost every day. Not sure if that is related.

You said you already tried installing the USB drivers again and said it didn't fix it. Did the install complete successfully or did it state newer drivers were already installed? What about uninstalling and then reinstalling the drivers?

It said the drivers were already up to date. I wasn't sure if it would be a driver issue though since the monitor works perfectly fine if its the only one plugged in. If it was a driver issue it wouldn't work at all would it?

Update: I checked the history of the adapter and it didnt show anything had changed since I initially installed it.

Check you settings with just one monitor working. See if you are extending your desktop or mirroring it. Let me know.

I'm extending it.

Make sure the 'Display Settings' is configured to extend the desktop over all 3 displays, not just 2 of them. Steps for doing this can be found here: http://www.intel.com/support/graphics/sb/CS-033714.htm

The problem is that when I plug both monitors in, it only detects one of them now. I have both plugged in but only the usb to vga adapter monitor is working, and the hdmi monitor isnt even being detected.

 

[ltylert1996]

After continuously messing with it, it works. I went to my displays and even though my third monitor wasnt being detected, it gave me the option to mirror on the third monitor so I did. Then I switched it back to extend, and its extending to my third monitor again. No idea what the issue was or why that fixed it.

Glad you got it working.
Thanks for posting how you did it, too!
