Second Monitor (HDTV connected via HDMI) Not Detecting Input from PC

[CK011885]

I'm using Windows 8.1 and have a 27" monitor as my main display, and had a 40" HDTV connected as a secondary that I would watch shows on. Everything was working fine until the new speakers I ordered got here, and I was doing the wires in the back, the HDMI cable came out of my GPU. I went to plug it back in and thought everything should be fine, but now I can't get anything to display on the HDTV.

The odd thing is, Windows detects the second screen, it shows "SAMSUNG" as it always had while it was working, and if I turn the TV off, it no longer detects it. The problem is on the TV's end, I have the HDMI cable (It's HDMI-HDMI) plugged into HDMI4, and when I go to select a Source, only TV/PC are listed as they always are, but HDMI4 is not showing up. If I try to select the grayed out HDMI4 it tells me something along the lines of Source Not Found.

I tested the HDMI cable with another monitor and it works fine, the HDTV is connected to a cable box via HDMI2 and works fine, so I tried plugging it in there and it doesn't work. So the HDMI port on the TV is fine, the HDMI cable is fine, Windows detects the screen, I can't figure out why it won't pick it up as a source. While Googling, I saw something about unplugging the power on both the computer and TV along with unplugging the HDMI cables, I gave that a shot but it didn't work. I've also tried the Windows Key+P functions and nothing shows. I'm completely stumped.

try to turn off and disconnect your monitor, disconnect any hdmi from pc, leave only tv as a monitor with 1 hdmi (pc<->tv). if your tv connects, add other cables and your monitor. if not try other hdmi ports or other cables.

Sorry to bump a post I made from January but I'm having the same exact problem again. The dumbest part is I resolved this issue in January, but for the life of me can't remember how. Just now I tried disconnecting everything, I even opened up my case and took the CMOS battery out.

This is the same exact problem again, same Samsung HDTV. What happened was the new monitor I bought in January turned out to be a dud, I returned it for a refund instead of replacement. Now I bought a 2nd monitor again and was trying to set both up, and here I am. I really wish I had a better memory as to how I got them both to work, but I'm clueless.

Done. This seems to be a somewhat common issue with seemingly numerous remedies according to this thread I found here:

I read through the whole thing and tried them all with no luck.

Try plugging the TV as the main display source as the GPU may prefer it's bigger screen then connect the secondary screen and try playing with the WinKey+P combo and set it to extend.

That worked for me when plugging a 24" with a 19" dual monitor setup i tried a few months ago also check if your TV has any DVI or VGA, TVs may prefer those output for PCs if the TV is old enough.
