I have my pc hooked up to a LCD TV it has a hd4600, also hooked up to the tv is a cable box and fire tv. The problem is that when I switch to the cable box or fire tv then back to the pc the video does not sync up and just flashes from static to black. If I remote log in to the pc and switch my display refresh rate to 24hz then back to 60hz the video comes back on. Untill I switch inputs again then it happens again. I used to have this problem with Nvidia cards but they added the ability to disable the monitor detect pnp setting so that once the monitor is setup up it doesnt switch. This seems to not be in the Intel drivers. Does anyone know how to fix this.
My recommendation is to run the latest driver update. Here you can get it:

Please make sure you have the latest TV box firmware update installed and try direct connection between the monitor and the TV.
