can not extend monitor on build 9926 but could in old one

Dude · 24 Jan 2015

Did you do the upgrade install, or clean install?

Okay, let us know. Others had had graphic driver issues too. Good luck

maybe the problem is all the amd drivers are for windows 8.1 but as I said, it worked fine on the earlier build.
thanks anyway, good night.

Don't know if it's relevant, but are you in tablet mode?
It disables all auxiliary monitors.

I bagged it and went back to build 9879, the second monitor is working fine again. I can't live without it and my old inspiron is too slow. I liked the new build but without a second monitor I can't use it.

by the way, no I wasn't in tablet mode. I clicked it to see if it mattered but it didn't.

That's a weird problem because I never had issues running 4 monitors on any build including this 9926.

I had the same issue on my desktop PC with the stock drivers. Only one of my monitors showed up. It didn't matter where you looked, only one monitor was detected. Once I installed the NVidia drivers for my GT 640 I got the option to extend to all three. Shortly after that though I had issues that ultimately resulted in me going back to 8.1. I'm not sure if it was driver related or not. I had a couple of BSOD and an endless reboot. Enough was enough at that point.

official release later this year will likely have this issue corrected, we ca hope so anyway

New compatible drivers will eventually show up, and be available though Windows update. NVidia, AMD, etc have to build the drivers and then submit them to Microsoft. A new build depending on what they change from the last one may mean new drivers are needed. I just used the latest version for my card for W 8.1. I'll have to go see if there is actually a Windows 10 version. I just used what I had already downloaded a couple of day ago.

EDIT: I just had a quick look on NVidia and didn't see anything listed for my card for Windows 10.
