GTX1060 can't see LG TV as second display

[shimmler.89]

Hello dear community!

Sorry to trouble you, but I have an issue that I can't solve and thus really need your help.

A while ago I had a system with GTX980 (on Windows 7) that had dual-display system with LG monitor and LG TV.

I upgraded my rig and now I run GTX1060 on Windows 7. At first I was just using the LG monitor connected to the GPU via the DVI port (with DVI to HDMI cable), but today I decided to connect the same LG TV from before using the HDMI port.

But for some reason my PC just doesn't see the TV - the second display can't be found nor in the Nvidia panel, the Display setting panel, control panel, device managers - anywhere. The TV also states that there's no signal.

At the same time I know that the TV and HDMI cable are working correctly because I plugged them to my Acer laptop and it instantly hooked up to TV as an additional display.

I tried updating the display drivers on my PC, trying to force-detect a TV, restarting the system - all to no avail, it just wouldn't notice the connected TV in any way.

Please help 🙁

It’s not a really long HDMI cable, say 5m or 10m?

It's about 6m long, but can it really be an issue considering that it works with laptop just fine?

Up.

Okay, is there any way to make sure if HDMI port on GPU is faulty?
