I have an i7 PC with Windows 10 & an Intel HD4600 graphics card. I have one DisplayPort connected to a standard 1080p monitor, and the other Displayport to a 1080p HDTV. Until a few days ago both were working and I was able to use both or either. I had to reinstall the intel HD 4600 driver, and now I get nothing on DisplayPort #2. I confirmed that it is the port and not the cabling by switching my (working) monitor cable from DP#1 to DP#2. Nothing at all.
Until I connected the monitor to DP #2, the Intel Graphics Properties and Graphics options did not even recognize a second monitor. But now they recognize both the "Digital Monitor" and "Digital Television" and offer the option to switch to either, both (extended), or both (cloned). But in all configurations there is no signal at all on DP#2.
How can I get it working again?
