I updated my Windows Tablet Windows 8.1 to Windows 10, then found I could not run an external monitor from the micro HDMI port as I use to with Windows 8.1. I used the Driver Update Utility to download and install HD Graphics Driver for Windows 10 32bit 184.108.40.20652 BUT IT DOES NOT WORK.
I really need this dual monitor to work because I am a classroom teacher who displays student notes onto a video projector connected to an IWB.
SO can somebody PLEASE FIX THIS MESS!
I would recommend to contact Microsoft in order to get the driver from their site, you can try with our latest graphics version Download Intel® HD Graphics Driver for Windows® 7*, 8.1*, 10 (3rd Gen & BYT) but since our driver are generic the performance of it will depend on your computer's hardware configuration.
