So my boyfriend has a HP laptop with windows 8 on it, we use it & an HDMI cord to project stuff from it to the TV. No problems at all.... Until we updated to 8.1. And the frustration begins. Every time we plug the cord in now the laptop screen goes black and nothing is projected on the TV. Before the update they would play on both the computer and TV. I've tried the whole windows button plus p thing and changing resolutions but I don't know or like windows 8 so I'm kind of at a loss at what to do.

Please help!

Go to HP Support and d'load the latest Display Driver. (Save to disk)
Uninstall your present Driver
Windows Key plus X
Device Manager
Expand Display Adapters, Rt click each and choose 'Uninstall'
Go to saved Driver, Rt click and run as Admin.
Hopefully all will be returned to normal. Last resort, revert your Laptop to W8 using Recovery.

I had the same problem not an IT tech but was able to do it. I right clicked on the desktop 2. go to graphic properties 3. Click advanced mode 4. Click on multiple display then select clone. After doing this both my laptop and tv were showing the same info. Previously once my HDMI cord was plugged in my laptop would turn black and he TV only was displayed. Now after taking these steps I can now see both screens.

If you have a function button on the laptop look for a HDMI in function usually on F9 or one of the F1-12 keys. I had the same issue and when i pressed the Function + F9 (HDMI) it enabled both monitors and stopped blacking out the laptop screen.
