Windows 7: bundling HDMI cable together with USB 2.0 cable will be interferences?

bundling HDMI cable together with USB 2.0 cable will be interferences?

If I tape together tightly HDMI and USB cables for a 15 foot run, will they cause any interference?
I know they are digital signals so I think should not. But doing this does cause a herring bone interference with analog vga cable.

It depends on the quality of the cables insulation and shielding.
The only way I know how to find out for sure is try it.

A digital signal should not degrade enough that you would see it, so the HDMI should be fine as far as your eye can tell. The USB is a differential signal and will automatically reject noise just by the nature of the signal.

That being said, a lot depends on the quality of shielding in the HDMI cable. If it is at least 1.3 compliant and is of reasonable quality, you should have no problems. But, as Layback Bear said, the only way to really know is to try it out.

The best way to ensure no interference is with separation (and good grounding). Short of good separation, make sure the cables don't run parallel to each other throughout the run. That is, twist the two cables over each other, over and over again, all along the way. In effect, you braid the cables together like braiding hair or rope - only with two cables. This crossing over of the cables will prevent/cancel out any "eddy" currents from being "induced" into adjacent cables.

If you look at common CAT-5e Ethernet cable, you will note it is "UTP" - unshielded twisted pair. Within the Ethernet cable, there are 8 wires in 4 pairs. Each pair is twisted together all through the cable, and all 4 pairs are twisted around each other all through the cable. The angles of these twists are actually at a predetermined angle based on the frequency of the signal running through the cable, to maximize the attenuation/cancellation of any energy robbing interference. By twisting the wires in this way, they don't have to use shielding around each wire, and around each pair of wires in the cable. This greatly reduces the cost of CAT-5e cable, allows for much greater flexibility, and smaller size too.

I hope it illustrates what you should do here.

One more word of caution. Do NOT tape them "tightly". The thickness of the insulation around each wire is not arbitrary. It allows for proper separation. If you smash the insulation, you reduce the distance between wires and that may cause interference issues. In cables that carry higher voltages, it can results in shorts. So you only want to tape them to hold them together "loosely".

That said, I recommend cable ties instead of tape. Tape turns ugly over time, comes loose, attracts dust bunnies, and leaves a sticky mess when removed.

I bought loom wire harness vinyl tape. This is not as sticky. Should not create a sticky mess.

Hmmm, isn't that tape for automotive wire harnesses? Is so, it is quite sticky. Either way, don't squeeze it too tight while wrapping.

The sticky mess I was talking about is if you ever have to remove the tape. Tape typically leaves sticky residue.

Just going by some reviews of the tape on amazon.
Also some harness tape has no stick.
A claim was handles heat well and does not go goey.

There should be no heat to worry about. And if no stick, the ends have to be secured some how.

Your choice. I would still use ties if me.

Why worry about bundling? Just pull some flexible conduit or plastic tubing and pull the cables through that. I've even used cheap garden hose for conduit for Ethernet cables.

Hi, well this is for a 37 foot boat navigation PC.
About 5 feet of this cable bundle must pass in front of an engine, (20 inchs away) in the engine room space, and it can get hot in there in the summer.

I am bundling an HDMI, USB, ethernet (used for on-off switch and LED lights), maybe a sound cable, all together as it is easier to pull and keeps them all together just for the computer. I have a navigation helm and am running about 16 feet to the PC desktop.

Sound can come in on HDMI. I have a radio that the sound cable can plug into on AUX, so then the computer can play sound onto the stereo speakers using the radio.

I bought this here, it is usb powered but will also work off HDMI power.

good reviews and cheap. My monitor is 17 inch VGA.

And I bought a female to female HDMI coupler. So HDMI out from PC to this VGA converter which also can make sound and it is powered off USB, of which I have a 7 port USB hub next to the monitor at the nav station for the keyboard, gps, mouse, etc...

I would like to leave out the stereo sound cable and just use HDMI for sound.

Will this cable work to extend coaxial cable for cable box?
Getting a new TV and placing it in a different spot than where the old TV is and I realized the coaxial cable coming from the wall isn't going to reach the new location for cable box's "Cable IN" connection. Can I use this as an extension? It looks right to me but I just want to be sure.
