I have done everything to try to get my second monitor to play again.  It started by only working when tricking the PC by disconnecting the 1st monitor for reboot first, then connecting, then later, that no longer worked.  Switched monitors and both work fine. Cords, connectors seem fine.  Many complaints on microsoft's discussion board.  All different situations or they were involving TVs and laptops.  Many, a year later unanswered.  All involved video drivers; however,, I think if one looks at it as an HDMI issue, it likely is a driver for Video, Sound,and Game Controller. I do not know what is missing because there is currently only an audio driver.  I know I can install an older driver in compatibility mode.  Any ideas?  I did try "install legacy drivers" on device manager.  Please help. I joined this discussion because it is the only one I have seen with recent dates on the Qs and As.  Thanx.  Miguel
