Random intermittent loss of Signal via HDMI to 4k TV

post #1 of 7
Thread Starter 
Anyone having this issue as well? Nvidia seems to suggest trying different HDMI cables but I never had this problem with my GTX 1080, it was only when I got the 1080 Ti FE, and the Titan Xp that I began experiencing this.

What happens is randomly while gaming or at idle the screen will go black for anytime between a 3rd of a second to about 2 seconds and then the image will come back. It also seems to happen regardless of GPU OC and regardless of whether the power profile in Nvidia Control panel is set to Adaptive, Optimal Power or Prefer Maximum Performance.

What's more annoying is I'm using high grade Audioquest HDMI cables, and I've tried 2 already. Also, I have 2 Gigabyte Aorus 1080 Ti's on the way and I'm curious to see if the issue occurs with those as they will be non reference cards, and the 1080 I used to have was also a non-reference card.

So... Anyone have a fix or insights? I think it's safe to say it's not my cards being defective as I've now tried 2 separate cards, and ?I refuse to believe it's these cables as they've worked fine for years with various other GPUs.

Card, cable or TV input... so TV input?

Maybe... I just switched to a different input. I'll report back if it does it again.

Same issue here. I just installed a new Titan Xp at stock frequency and it happened several times yesterday. It had happened a few times with my 1080's but it seems to be happening more often. So it happens to your Titan even under water? I had assumed it was just a heat issue and once I install my hybrid cooler it would go away. I don't think it's a cable issue but I'll try switching some out. Any other trouble shooting steps to suggest?

The other idea that came to mind was just a V sync issue with the display. It seems to happen more often when I run Benchmarks with no Vsync and the framerate jumps around a lot. I think these panels are partial to signals at consistent Hz. Not very scientific but just a thought.

Hi there, I have had similar issues and still do. Basically in my case it's my TV trying to protect itself from high refresh rate, try to set your TV to 59hz from nvidia control panel and most likely the problem will go away, that's what solved my problem. Soon as I put it back to 60hz, it will randomly do that while gaming or doing anything pretty much. So basically try to lower the monitor's hz by 1, if it's 60, set it to 59hz

I had the same problem and it seems to be the setting on tv that enables HDMI ultra hd deep color or HDR. Toggling that to off did fix the problem.
Also in Nvidia Control Panel on setting 3. selecting the output dynamic range to limited fixes the issue.

Seems I'm not the only one... That makes me feel a little better. I switched the HDMI port to on my one connect box *Samsung port hub* to the ACR input and I haven't had the issue since... Strange.

My Nvidia control panel looks like this.
