This is a Windows 10 issue.

I have an HP Probook 4710s with an ATI Radion 4300 video card.   When I installed Windows 10 Insider build 10162 everything worked perfectly.   Specifically, I could connect to my TV via HDMI using "Windows" "P".

I just upgraded to the latest supported build. I suspect that the video driver has been "updated".   Bottom line, I now cannot connect to my TV.   "Windows" "P" says "Your PC cannot project to another screen.   Try reinstalling the driver or using a different video card."

The hardware obviously works since everything worked under build 101762.   I'm not a technical guy, but it's gotta be the software (driver).   So I'd simply like to replace the current driver with the one I had with build 10162 but I have no idea what I'm looking for.   (If I get there I'll disable future Windows 10 attempts to update this.)   Can some one please point me to the *CORRECT* driver for my system?   (i.e. the driver I had in build 10162?)    Device Manager says it is an ATI Radeon HD 4300 series.  The current (problematic) driver is

     Driver Provider:     Advanced Micro Devices, Inc.

     Driver Date:           7/15/2015

     Driver Version:      15.200.1060.0

     Digital Signer:       Microsoft Windows Hardware Compatibility Publisher


I also have this question outstanding via email but I guess they are backlogged and I would like to get my TV back!   :-)

Thank you.   Regards, Brent.
