TV problem

Racovel · July 27, 2017

Hi guys. My name is Raco and i have a problem with my PC setup.

I have a PC 2 years old now but i have made some improvements. It's a core I7 4790, 16 GB DDR3 RAM, GTX 1080 Founders Edition from Zotac, Crucial 256 GB SSD+ Samsung 850 EVO 1TB SSD all on a ASUS B85 gaming motherboard and connected to a Samsung UHD 9 series Quantum Dot 49 inch TV. The problem is that ever since we got the TV, the connection to the PC is not stable. From time to time the TV screen goes black for 1-2 seconds and then comes back.

This happens at random and in any situation. Gaming, or watching YouTube or a movie or just on the desktop doing nothing and it will not stop unless I unplug the HDMI cable from the PC and plug it back in. the frequency increases drastically if i change the in-game resolution. Before having the GTX 1080 I had the GTX 970 and it did the same thing. I have tried different HDMI cables, lengths, thicknesses, pricier, but nothing. I have read online that the TV has some power saving modes and I have disabled them, but no luck so far.

I have attached a video as well.

Any help would be deeply appreciated.

All the best,

Raco.

While I get that you've tried multiple HDMI cables, since this is a TV I'm wondering how far away it is from the PC. Exactly, how long have the cables you been testing been?

The PC is next to the TV, a standard length HDMI cable is enough, I have tried different lengths to make sure is not the cable's fault.

Those sound like driver problems to me, especially with the screen blanking every now and then... or a bad connection maybe.

Or it could be the TV itself, have you tried other sources connected to the TV for comparison? Checked that the power connector is fully seated, I have seen this before when I got called out to check a TV and the guy hadn't inserted the TV power connector into the back of the TV fully... once inserted fully the problem went away.

I have tried all the available HDMI ports on the TV's ConnectBox, and none of the other connected devices have any problems: a Skybox (digital TV broadcast in England), a laptop or a Chromecast. As for the power connector, it does't go in any further, i just checked it :(. And I have also tried with the on board HDMI output from the motherboard and it still does the same. As for the drivers I have GeForce Experience installed and it alerts me when a new driver is available and I install it.
