Windows 7: Monitor not Recognized after Windows Update

Monitor not Recognized after Windows Update

Hi guys,

I got this problem probably 3 days ago, I woke up one morning and saw that my computer had restarted itself from a Windows Update.

I turned my monitors on, and it only seemed as if one was plugged in, (the Samsung on the right).

So I checked connections, had a look in screen resolution settings and CCC, and neither could detect my ASUS on the left.

After more screwing around, I unplugged both monitors, and then just plugged in the ASUS using its own cable and port that it always uses, and the screen came on.
So to me, this rules out cable and GFX card problems?

I now see in CCC that the ASUS is an Unknown monitor, it ALWAYS used to say ASUS.




Now when I plug in my Samsung, the ASUS turns off and the image moves over to the Samsung.

For the ASUS I use a DVI to HDMI cable (HDMI end at GFX card)
and the the Samsung uses a regular DVI cable.

Thanks guys

Forgot to add; I also tried graphics driver rollback, uninstall Windows Update and then downloaded latest AMD graphics drivers, none of which seemed to help at all.

Don't that will work since it is after the problem. Try this click start/devices and printers, right click the monitor and click troubleshoot.

hi, I have a couple of screenshots for you:


This is with ASUS plugged in:







This is with Samsung plugged in:





So as you can see, I can't right click it :/

I also tried to right click it in CCC, but its not possible to do much from that program...

cheers

Graphics Card AMD Radeon HD 6700

HDMI port: HDMI-to-DVI cable to ASUS
DVI port: DVI cable to Sammy

It doesnt matter which ports or cable I use though, same thing happens

okay lets try this. hook one of the monitors to the onboard video. You will have to go in your bios and enable multimonitor and you IGPU.

Here is a link to your manual to view the BIOS settings
