Hi Scott, Thanks for responding.
- Driver Version 10.18.10.4885
- Driver Date 11/12/2017
which the Driver & Support Assistant says is the current version for my mb
No, it doesn't matter if I cold start or reboot, or even if the monitor DVI-D monitor is powered up. If its plugged in to the DVI-D port, the system thinks I have two identical Dell monitors installed and loads drivers accordingly
Hi @Stal the Dell U2414H does not have DVI input on it if I'm not mistaken, it only has HDMI's and Display Ports. Are you Using an adaptor to connect to DVI on the DQ77CP ?
If you are using adaptor maybe try another adopter cable it might be at fault.
I have the Dell U2414H as one of my monitors stored somewhere in the house, I checked it and it doesn't have any DVI inputs natively.
Did this ever work correctly or has this problem always been there?
If it has always had this issue, my response to this would be that there is likely a BIOS bug and that you should upgrade your BIOS. Since this is an Intel Desktop Board and since it has long been in EOL status, however, I know that there is no chance of seeing an updated BIOS that fixes this issue (you *are* using the latest available BIOS, right?).
Have you tried using a dongle to feed this output into the DP or VGA input?
Thanks for your input. I think I have resolved this - more by luck than judgement.....
I think this is a Windows 10 issue
- I booted the PC with both monitors connected
- In Windows I manually selected the VGA driver for the VGA display (i.e. changed it from being a duplicate of the Dell monitor)
Now it would seem that when I reboot (re-start or cold boot) the system "remembers" and loads the correct drivers....
Again, thanks all for your help
