Windows 10: Mini DisplayPort fails with upgrade from Windows 8.1 to Windows 10

When I upgraded my Surface PRO 2 from 8.1 to 10, the mini DisplayPort would not work. I verified that Windows 10, drivers and firmware were all up to date. With help from MS service, the following worked:

• To open Device Manager, click Start, click Search programs and files, and then type Device Manager. A list of available matching items appears above the search box; click Device Manager. Device Manager opens with your computer name at the top and a list of devices that are installed on your computer beneath your computer name.
• Locate the malfunctioning device in the list of devices, right-click the device, and then click Uninstall. When a warning message appears that you are uninstalling a device from your system, click OK. Device manager uninstalls the device.
• Right-click your computer name in Device Manager and click Scan for hardware changes. Device manager scans your system and automatically reinstalls your device.
• RESTART
• Right-click the device and click Properties. On the General tab of the device Properties dialog box, in Device status, you should see the message This device is working properly.

Note that originally, I followed thru Step 2 and then did an Install from the Device Manager menu and this failed. I tried several times. However, Step 3 above "Scan for hardware changes" worked.

Other than that, the upgrade was seamless, with a few quirks, having to get used to a new interface plus MS Edge. I like IE just fine but now it seems to fail frequently when Edge is also active. I am one who liked Windows 8.1 just fine. Hopefully, I will like Windows 10 once I get used to it. Also, RoboForm will not work with MS Edge (Ugh!).

After upgrade to Windows10 Surface 3 mini displayport not working

I upgraded my Microsoft Surface 3 from Windows 8 to Windows 10 over the weekend. The mini displayport worked fine before without any problem. But, now after the upgrade to 10, my displayport is not working. It's not picking up any monitor signal. For
example, the Display port of the screen resolution thinks that there is no other monitor connected at all and I don't think is detecting the displayport. In the Device Manager, under Display Adaptors and under Intel(R) HD Graphics Family, it says, " Windows
has stopped this device because it has reported problems". Is this graphics related to the mini displayport? What is the issue here?

 

Windows 10 external monitor via surround receiver, no signal

Hi,

I have one monitor connected to AMD Radeon HD7950 via direct HDMI cable, and TV connected via Pioneer VSX-924 surround receiver using Mini-displayport-HDMI adapter (so mini-displayport-HDMI adapter from HD7950 to receiver,
and normal HDMI cable from receiver to TV). On Windows 8.1 it works fine, but on Windows 10, the TV is no longer receiving signal. Windows 10 is detecting the TV device just fine, I can see it even in AMD Catalyst Control Center, but TV is just saying "No
Signal". If I connect the mini-displayport-HDMI cable directly from HD7950 to TV, it works fine, so it only stops working when going via the surround receiver.

I have the latest Radeon version 15.7.1, and all updates installed to Windows 10. Is this Catalyst issue or Pioneer receiver issue or Windows 10 issue? Is there anything else I can do except wait for update to one or more
of the three? I've since reverted back to Windows 8.1 as HTPC is useless if it cannot send signal to TV.

I tried removing Catalyst drivers and reinstalling everything, no help. I even did a clean Windows 10 installation, still the same behavior.
