HDMI connection issues

[Aelita Sophie]

Currently 1 of the screens sometimes turns black, the other screen sometimes has red lines and also occasionally turns black.

These are typical indications that the incoming signal is to weak.

 

The setup:

I've got my PC in a separate room. On the GTX1060 6GB I've connected 2 DisplayPort to HDMI connectors. (Generic Aliexpress)

On that connector I've got a HDMI to RJ45 (Cat5e/Cat6) converter. The "not-the-cheapest"-kind, thus only 1 ethernet cable is needed per screen instead of 2. I've tested this out with several lengths of Cat6 cable, and typically it was working fine. But with the issues as described above. Now this doesn't happen constantly, only once in a while. However the red lines happens the most. Using a HDMI cable works fine, but don't have the required length (about 20ft) and aren't easily pushed through conduit in the wall.

 

So clearly it isn't working properly. I personally think it's due the length of the Cat6 cable, losing it's signal strength. However my budget isn't as big and from what I know, I have 2 options:

 

Option 1: Put a HDMI repeater/amplifier before it goes to the Cat6. ( for example https://www.aliexpress.com/item/-/32833277921.html?spm=a2g0s.8937460.0.0.417f2e0ePc1kTb )

 

Option 2: Replace the HDMI to RJ45 converters with HDMI over Ethernet adapters. ( for example https://www.aliexpress.com/store/product/Elistooop-1080p-3D-HDMI-Transmitter-Receiver-60M-HDMI-Extender-US-EU-Plug-Cat-5e-6-RJ45/3221116_32863267761.html or https://www.aliexpress.com/store/product/Neoteck-1080P-60m-HDMI-Extenders-HDMI-Repeater-Over-Cat-6-Cat-7-Ethernet-Cables-With-IR/3282010_32841826245.html )

 

What do you guys think?

 

 

(Also, yes there is also some interference due the fact that my gaming-rig is in a serverrack, with a bunch of servers. Of which the cablemanagement.. well.. doesn't exist yet)

You mentioned that your machine was in a different room so I went to Newegg and looked at some of their hdmi cables.  They have some as long as 100 feet.  Check it out.

Can't pull those throught the conduit. Connector is bigger then the diameter of the conduit

With a little American ingenuity, I was able to run an HDMI cable from my machine to the television in the other room.  Measured distance from the corner of the room with my poorter to the center of the room, distance of five feet.  Crawled up in the attic and drilled hole in the wall support to pass the cable down into the wall, then cut hole in wall 16 inches from the floor.  Took the long HDMI cable up into the attic and lowered the end of the cable down thru the hole I drilled and then pulled the cable out thru the hole that I cut in the wall.

 

Did the same in the room with the entertainment center in it passing the cable down thru the hole that I drilled in the top of the wall inside the attic and pulling it thru the hole that I cut in the wall in the room.  I used a 50 foot cable and not the 100 foot.  Yea, I have a few extra feet of HDMI cable rolled up in the attic but it looks good and works great.  I used some outlet covers over the holes in the walls in the two rooms so the only thing you see from looking at it is nothing more than the cable coming out of the wall.

 

If you didn't know better, you would think that it had been installed that way when the house was built but since the house is 25 years old, we know that didn't happen.  I left 8 feet of cable hanging outside the wall in both rooms so there is enough cable in the room in case we want to rearrange the furniture.

 

Good luck.

Well, I'm european, and our houses aren't build like that. Especially since this house is from the early 1950s (if im not mistaken), I can't easily make those adjustments. All the walls are solid, either concrete or gas-concrete. The conduit I managed to get into the wall, by literally chopping in the wall with a big hammer drill, put in the conduits with the proper bends, boxes etc. And then filling it up again with plaster. Is quite smaller then a HDMI connector. 1 Conduit passthrough can hold about 3 Cat6 cables snuggly. I've got 3 conduit lines, so enough for 9 cables. 6 for screens, 2 for USB (got 2 systems here) and 1 for shared audio streams (if I ever going to do that, might just pick up USB Audio boxes)

 

Anyhow, I'm asking if I should go with a HDMI Amplifier or just go with a HDMI over Ethernet system instead of a HDMI to RJ45 converter. I'm well aware that the latter can introduce some output lag.
