External Monitor via HDMI turning on and off

[germormal]

Hello. I just got a Omen Gaming Laptop, model 15-ce0xx and a Samsung 4k monitor model ue590. The laptop comes with a Nvidia 1050ti card, so it should have no problem giving out a 4k resolution on windows, not on games, but at least on windows to work with premiere pro and photoshop.

My problem is that everytime I start working, the monitor starts flashing on and off, like if it's trying to detect which input should display. Sometimes it happens with chrome, sometimes with premiere, sometimes just using windows. I've tested the monitor with other computers and it doesn't have this problem, so it's just with this laptop.

I already updated all my drivers and even installed a bios update on the laptop with no luck. I don't really know if it's having a conflict with the Intel Integrated Graphics and Nvidia drivers. 

Anybody has any ideas?

Thanks 😄

Your machine has

   HDMI: v2.0 supporting: up to 4096×2160 at 60 Hz with HDCP 2.2

Now my question: what is the version of HDMI cable do you have ? You need HDMI v2.0 cable.

Regards.

Thanks for the quick reply. I tested 2 cables so far. The one that came with the monitor. It says it's high speed and has ethernet. The second one it's an amazon basics hdmi, also high speed with ethernet. The website says it's hdmi 2.0. 

In any case if the cable is not a 2.0 hdmi, that could be causing the problem?

On the other hand, would you recommend if i just got a mini display port to display port cable? I suppose that's better than HDMI. 

Thanks.

I had the same problem you are having now and mine has a GTX 1070.

I also ordered new Amazon HDMI cables (I didnt realize I got the one with ethernet until it was too late. The e cable is thick and ugly and a waste of money, but if you already have it, no worries) but that didnt help.

Then about a month later, (I assume after some windows updates) mine magically started working. The cable did not matter, the old one worked.

Before this happened, I could get it to work sometimes by switching resolutions back and forth from 4k to 1080 in the nvidia settings.

Also look at the refresh rate. If its set on 60hz, can you lower it?

On a side note:

I have seen several complaints about the Omen's HDMI port. I think what ever is causing your issue is also responsible for Oculus Rift users to have to use the Mini-Display Port with an adapter.

I also tried the Mini-Dsp adapter and it worked fine. Went to BestBuy (USA) and got the Insignia adapter for Apple (it works on Windows also). But the Amazon version is much cheaper.

Hope it helps.

Thanks for the help. Yes, I can lower the refresh rate, but the problem persists at 60 and 59. If I go lower, everything looks a bit laggy. 

I already ordered a DP cable and a hdmi 2.0 cable, I'm sure any of those should work haha. 

I'll let you know how it went tomorrow when the cables arrive.

Quick update. Tested it with a 2.0 HDMI cable, still flashing on and off. I'll try with a DP cable later today. I'll post my results.

The mini DisplayPort to DisplayPort did the trick. The HDMI 2.0 cable never worked. If you're having this problem, get a DP cable.
