Hello guys, I'm new to this forum!
I'm sure many of you are great problem solvers when it comes to PCs, so I need your help.
My current system:
Windows 10 PRO, 64bit
Intel i5 3570k - CPU
EVGA GTX 950 SSC - GPU
GA-Z77X-UD3H (rev. 1.1) - Motherboard
Seasonic 620w - PowerSupply
16GB(1600 Mhz) Corsair Vengeance DDR3 - RAM
The problem: When I connect an HDMI cable to my TV from my GPU, I get No Signal.
A more detailed explanation:
A few years ago I bought an MSI GTX 660 Graphics Card. The card worked just fine, connected it through DVI to my monitor... all good so far. Then I tried to connect it to my TV(32 inch LG LED) as a second monitor through the HDMI port. I got No Signal. No second monitor appearing in Display Settings, nor inside Nvidia Control Panel. Windows project to a second monitor(extended, duplicate) didn't work either... TV not recognized at all, nowhere, not even in device manager.
Then I tried the other DVI port on the GPU: that worked just fine. So 2 monitor setup worked: DVI to monitor and the TV was connected through the second DVI (with DVI to VGA adapter, because the TV has VGA). But I didn't like the idea of bringing sound to the TV with an extra cable... So I went a diferent route: I decided to connect my TV through the HDMI port on my motherboard. That worked just fine, we got signal.
So Internal GPU(HD4000 from the CPU) was supplying the graphics for the TV and my GPU was powering my monitor graphics. But I still didn't like the idea... picky...
At a later time, I tried the HDMI port on my GPU again, no success. A friend suggested I try to use the display port on the GPU and go with DisplayPort to HDMI to the TV(TV has HDMI). That didn't work either... No Signal...
In case you're wondering, the HDMI cable works just fine, HDMI port on TV works just fine. Same cable and tv port work through mobo HDMI or other sources like a laptop.
I also tried changing settings in the BIOS, with no success. Disabled the internal Graphics, disabled CSM support, tried what I read online.... no success. My conclusion: 2 dead ports on my GPU(HDMI and Display Port)... so stuck with re-enabling internal Graphics and running the TV through the mobo HDMI.
Some time has passed... a few years... And I sold my GTX 660... I bought a GTX 950. Put it in my system, latest drivers installed. Connected my monitor through DVI. All worked fine. Then I connected the TV through the HDMI port on this new GPU. Guess what? No signal... AGAIN!!! TV not detected...
What could be the problem? My motherboard? I updated the BIOS to the latest version, still no success...
I really don't know what to do...
Your help is much appreciated! Thanks!
