New replacement Rift no longer works with HDMI extension cable

Hi,

a few days ago, my Rift headset broke (one earphone stopped working) and I RMAed it at a local hardware store where I have bought it. The very next day, I've received a refund, so I immediately proceeded to buy a new Rift from them. My first Rift was the original bundle that came with remote, XBOX controller and one sensor, but they are not being sold anymore, so I've gotten the new one, that's bundled with two sensors and a touch controllers. 

I did notice some build quality differences, such as that the new foam padding is made from a much cheaper material. I did not mind that, since I bought a VRCover one anyway. What took me by a surprise though, is that my new Rift no longer works with my 2 meter HDMI extension cable. If I plug it directly into my GPU, it works well, however if I plug it via the HDMI extension cable, I get just a black screen (but Oculus software does not report HDMI not connected warning). It is the very same cable my previous Rift worked with, and it is plugged in the very same ports. I don't think that the new units should have any significant hardware difference, which could cause this.

Is there something I can try?

Thanks in advance.

    Can you try with the new headset cable that came with the bundle?

    Well, I have only one cable, the new one. When I RMAed the old Rift, I of course had to hand over the entire box, will all the original contents, including the cable.

    Is the HDMI extension cable an active or passive?

    Passive, but as I said, it worked with my previous Rift. Also, it's just 2 meters, so signal should not get lost over such a short distance :|

    I understand, but I wonder if something might have gotten bent? Have anything you can test with the cable?

    Yes, that's the first thing I did. I've tested it with both my Chromecast and my Xbox One. No problems whatsoever...

    Try restarting the computer once the HMD is plug in if you haven't yet. Then try running the software again and then getting us the log with it plug in. You can get the logs here:

    Run "OculusLogGatherer.exe" by double-clicking the icon after navigating to this folder:
    C:\Program Files\Oculus\Support\oculus-diagnostics
    and upload the zip file to your post.

    Rift can be really picky about which extension cables work or not, even with a cable that worked on another unit. You may want to try with the specifically recommended cables here:

    I have recently received a brand new replacement Rift and i ran into this problem also... Where all the other replacement Rifts worked fine with extension (passive) cable but the new CV1 (circa April 2018) does not..
    I've had an email message telling me that Oculus do not support extension cables...
    Weird..! and i'd love to know more.

    The cable i bought and previously worked for two years is:
    • KabelDirekt 3m HDMI Extension Cable compatible with HDMI 2.0a/b, 2.0, 1.4a (Ultra HD, 4K, 3D, Full HD, 1080p, HDR, ARC, Highspeed with Ethernet) - TOP Series
    PS I've a feeling that Oculus have changed something. reading reviews of this extension cable on internet have many that say it doesn't work with Rift anymore
    Maybe a power/re connfigurement issue ? or the recommended sellers have a deal.. despite oculus not recommending extension cables (-:

    but i'm a cynic

    Well, it appears that my new unit is completely fucked up. It does not work even with just !20CM! long active HDMI repeater I have just bought. It really only works when plugged directly into GPU, but it's way, way too short for roomscale. I am really sad now, especially since I've sank another $30 for an active HDMI repeater that doesn't work.

    I havent RMAed my Rift or anything so its still the original one, and I have a 2m passive extension cable i used for over a year, but in the last 2 months its not working any more, at least in that you get black screens every few seconds before it recovers.

    It works fine still without the extension, so I'm not too worried, but the extra cable was always really useful.

    I might try getting a new cable, as it was only a cheap Maplin extender, but it is so much better when you use an extender :smile:

    Hi,

    so I've finally solved it. Turns out Rift is picky even about active HDMI repeaters. But I have finally found one that works.

    Solution in this case is indeed getting an active HDMI repeater, but not every one of them may work. The lesson learnt from this is that quality of Rift's hardware can radically differ between units.

    Im happy you've solved it, would love to do it myself but the cost of trying different cables has put me off, just out of interest can the extension cables be used on the sensors as well?

    Well I wouldn't call it the quality of the rift in this case. Long story short: Electronics are picky and we can't always tell that from face value.

    There are things call single quality and that is where most problems come in from. We can't see it - but at the single level it has to be perfect or else it just simple doesn't work. Really this is more of a problem of HDMI than it is with the rift it self. Sure it might have work before - but as things age - things just change over time and as result - work one day and not other other.

    I'm having the exact same issue. After I received my new Rift my previous HDMI extension isn't working anymore. I even tried a different extension with no luck. Would you mind sharing the model of the HMDI repeater that ended up working?

    This one worked for me after I was having the same issue.

    You can also try one of these to act as a repeater for you.
    you would be surprised how often this fixes issues for folks.

    Without extensions, mine works fine. With extensions, a short 3ft HDMI works fine, but adding the above repeater makes it fails (may indicate the quality varies, but not sure). A short USB extension causes the screen to occasionally black out (I have tried USB with repeaters and also an additional USB card with independent power supply.)

    The repeater got my Rift going again with an extension, but I must be right on the edge of what my power supply can provide, as the PC wouldnt boot up until I'd swapped my Rifts USB to an onboard USB 3.0 hub off of my Innotek USB 3.0 addin card.
