    Hi all, I would like to follow up on this. Last week I received my Touch on launch day and after 2 frustrating days suddenly got a message that my (third) replacement Rift + Extra sensor would be at my doorstep on Friday!

    Instead of getting wasted at the club after work I was eager to try it all out and guess what ... everything works perfect! I didn't have even ONE disconnect. I was always afraid it could be my older motherboard but apparently it is not. What I also noticed is that the God Rays are reduced. Instead of "rays" they are now more like a glow. Still very visible but since it's more of a glow they are not moving around as much when looking around.

    The 3 sensor setup was no problem even with xbox controller and wireless keyboard and mouse installed. I even have the unsupported Asmedia controller enabled to attach my steering wheel and joystick. It all works fine. So just for people arriving here after a search: If you have the problem that your Rift disconnects when touching it (especialy the left side) or slightly flexing it (it flexes when taking it off with one hand) and you tried most other things to try, then your Rift probably has a hardware defect. My first Rift got this after about a month. My second Rift was DOA and had it after the first minute (this made me really afraid that it was my pc ... what's the chance of getting 2 Rifts with exactly the same problem ... ).

    My setup: Asus Z77 LE mobo. Inateck card. Win10 x64, 980TI.

    I have my Rift inserted in USB2, 2 sensors in inateck (correctly seen as USB3) and back sensor in Intel USB3 (but gets recognised as USB2 because of the provided extention). It works flawless, tracking is flawless. Using latest Inateck 3.6.9a (or something) driver. I killed the Fresco process in task manager and since then also have no more occasional blue screens.

    There is one thing different with all other Rifts and I don't dare switching it around as a test afraid of having the same problem again: I bought a "cable matters" Displayport to HDMI 4K adapter and Rift is not connected to HDMI but to Displayport. I had ordered it but it arrived too late to try with the broken Rift.

    TLDR; If you are having HDMI disconnects (notification in tray reads "we can't find your headset, please connect your headset" and this happens when taking on/off the Rift or whenever touching it somewhere on the left side or slightly flexing it (so it's not random, you can trigger it most of the time) then it's probably hardware and you should return. To be 100% sure try with a friend with a different PC set up that is up to running Rift. It should have the same problem over there from the start. Get a replacement. If it's still broken, get another one. I'm on my third Rift and now have no more issues.

    Hi all,

    i face the exact same problem.

    Oculus Rift suffers from repeating HDMI disconnects when device is "hot" (turned on for around 10 minutes) if soft pressure is applied on the left side, the device is adjusted or bigger movements are made (touch).

    You can check the video here:

    Despite the fact that this is always reproducable and it therefore looks 100% as a hardware fault i did the following things:

    - Switched around to all other USB Ports.
    - Made a clean graphic driver deinstall and reinstall.
    - Used DNACowboys method of cleaning usb stuff in device manager.
    - Disabled all USB energy saver options.
    - Deplugged all other USB devices.
    - I have a fully supported Asus mainboard. All checkmarks in Oculus Software are green.
    - Replugged HDMI cable on both GPU and Rift. All pins on hdmi cable look good.

    This thing is going back to the vendor. This has to be a systematic hardware error.

    Mine started doing this after 2 months. I enabled the do not disturb feature and the screen goes black for a second or two and then goes right back to game without further drop outs. However, the PC screen still shows the headset in error. I think this is a headset internal error for sure.

    Hi all,

    just for info. Contacted merchant today, is returning money with no problems. Can buy a new - hopefully fully working - Oculus Rift today. Will report back after receiving new unit.

    Edit: New unit is working now without problems for about 3 hrs -> get your faulty headsets replaced.

    I have a brand new Rift and I am having this problem. For the most part it only does this when I'm adjusting the position on my face. When I let friends use it, the disconnect happened more often when people were wearing glasses and the glasses pressed against the sides inside the rift. I'm relieved that it isn't just happening to me but I was hoping to read about more ways to prevent it from happening. I'll try the duct tape and post my results.

    Shimster duct tape will not work. I tried this too. There is nothing you can do to prevent this beside not moving and not touching the headset. This is a faulty HDMI connector inside the unit. Get your unit exchanged asap.

    to ensure i don't pull anything and cause damage i did this


    This is my forum signature.
    There are many others like it, but this is mine.

    You may get HDMI signal loss error messages in cases where the sensors are losing power. Of course, the cable-to-HMD issues should be diagnosed and confirmed if suspected but, the messages could be sensor-related also but, not necessarily indicated in Oculus Home or Windows.

    If cable movement causes the connection-error, then HMD replacement should be the course of action; if it's not the cable connection, then check your USB-hub Power Management settings and the Rift-Sensor specific ones in Device manager should be checked and confirmed with Power-Saving disabled.

    I was getting the HDMI-disconnect error and Windows automatically enables Power-Saving for the add-in PCIe USB card I use for the Rift but, that wasn't the cause; the specific devices (Rift-Sensors) Power-Saving being disabled did solve it for me.

    Elboffer that's a great tip I did the same to mine after having to have my unit replaced due to HDMI issues. 

    Amazing oculus didn't fit some kind of stopper to the cable that can be removed to protect undue force being pressured on the headset connector. 

    Rule is if your headset disconnects when you apply pressure to the side of the unit where the connector is or to the arm next to it then you have a faulty unit. 

    I did all the usb fixes then DNA suggested and some of my own to stop my hdmi disconnects and it didnt stop. I started to look more closely at the hmd and finally was able to recreate the disconnect holding it in both hands and gently either twisting it or press down on the left hand arm, this triggered the disconnects.   

    Support very quickly issued a replacement unit. 

    To test oculus plug and play approach when the new unit arrived I did a complete reinstall of windows (10 pro) and made no changes to the usb settings. 

    With windows fully updated latest nvidia drivers (gtx 1080) and Fresco drivers, I installed oculus with touch. 

    So far so good and all working fine. I know doing the power management changes have helped others but for me it all works now as it should without any changes being done and leaving the power settings enabled.  

    My original unit worked like this for about two months before I started to get hmdi issues.  

    My setup is the sensors on the Inateck card and the hmd on the onboard intel usb.

    I had this problem of random HDMI disconnects and I realized it happened most when I was in the middle of a very intense bit of combat in games like Robo Recall.  I played with the headset a bit and found out that the cable connecting into the Rift headset was kind of lose and if I touched or messed with it even lightly it would disconnect.

    I decided to try something really simple to see it would fix the problem.  What I did was get some cellophane tape and I wrapped it around the rubber part of the plug just above the metal connector that goes into the Rift headset to make it thicker and give it less room to wiggle during intense play.  I then plugged it back in and gave it a go with Robo Recall and Raw Data, the two main games I got the most disconnects.

    So far it seems to have fixed the problem pretty well.  If you notice your disconnects come from intense play and touching the headset then you may want to give this a try.

    Oh, wow. This fixed my disconnect issues like a charm. I had taken the cable out of the retention bracket on the side and routed it directly trough a Zip-tie fastened to the top headband, because of the cable suspension i made from the ceiling. This made the hdmi plug wiggle around and disconnect during play. Routed it back through the bracket and ziptied to the back-triangle part of the headset and then routed it to the top, so no strain is on the plug anymore. Also gave the plug some tape, to make it more secure in the port. Works perfect now :D

    IVE GOT THE SOLUTION!

    You have to take the RIft face side off and plug the Cabel at the headset in and out again.



    In this video you can see how to do this. Its realy easy and takes about 1 minute.

    After a recent upgrade of mobo, cpu and graphics card I'm now getting the dreaded HDMI disconnects. Had my Rift since June and not a single problem with the headset until now. I counted myself lucky.
    I did have sensor disconnects, but they only happened when I wasn't using the Rift, so didn't bother me.
    Now the sensors are fine, but the HDMI thing has started. Most frustrating, as I've had no end of bother with the upgrade (see other thread about crappy Win 10 and going back to Win 7) and Windows etc, now it should all be okay finally, and this starts happening.

    I've had nearly 3 weeks of one off-pissing problem after another and I'm getting close to hurling it all out of the window and going back to my ZX81.

    (HERE'S A FIX NOT LISTED ABOVE) Here was my fix and explanation: My computer was too hot! Sounds crazy, but most computerS running VR are pretty heavy duty and can generate heat.  One of my fans was out, AND, I had my computer couped up in a corner with poor air flow.  Therefore, it was hot and hot air was escaping through my GPU inputs, which in turn heated up the metal dongle end of the HDMI cable that ran to the oculus on the other end.  It was so hot I couldn't hold it more than one or two seconds.  Once I fixed my fan, and got better air flow, the dongle didn't heat up, and viola, problem never came back!  Might be the other issues mentioned above for you, but check your HDMI dongle first to make sure it isn't piping hot.

    Seems, a problem is finally solved for me. The mainboard bends together with the whole rift when it's being moved or touched. In the middle of the board there is a STM32F chip located (iFixit teardown, step 9, yellow square) which has almost no space between textolite and chip's body. But since it is located in the middle, all bends come thru this point and bga connection gets broken. I've heated this chip with soldering heat gun (together with small amount of flux) and glued another piece of textolite to the backside of motherboard to reduce flexibility in this point. Since that I'm not afraid to make head movement or adjust the rift on the head. Disconnection problem has gone. Hope this information helps.
    P.S. English isn't my first language, so please excuse any mistakes.

    My god thanks ALOT.  I stopped using my rift because of this problem and didn't want to call support a 5th time about a "usb thing"  I noticed when the board was just lightly bent it went off.  I even thing the socket for the HDMI is not all on there either.  I am going to try this now.  Either that or trash iit, doesn't look like support was helping at all.

    Got my replacement Rift Finally... After four hours of the amber light and not being able to get it working I found a really odd quirk where I had a rogue file called 'Program' in the root directory of C Drive which was stopping the Oculus services from correctly executing the library and switching on the HMD... I was almost ready to give up when I finally looked really hard at the Oculus logs and found some references to not being a valid Win32 application, googled it, and saw a tip saying that's usually because of a space in the file path... Ha.

    Anyway, deleted that file, and holy hell it all seems to work. Didn't play for too long, but I kind of squeezed the HMD and twisted it a bit to the point where the other would cut out and this one is good... played a couple games for about 30 mins and not one drop out despite taking on and off the HMD a few times. I think this nightmare may be over 'touch wood'

    Time to try and forget this whole ordeal and just enjoy VR.

    Over and out.
    Sigh... I hate to dig up an old thread. But the same exact problem as I had earlier is now affecting my replacement rift... Its a damn shame I had this thing shelved for about 7 months, since just ordering the touch controls and another sensor finally this month, pulled out the rift again, and low and behold, same issue... HMD Cable socket faulty when the unit is handled and touched.... Unfortunately now the thing is out of warranty for about 8-9 months... Waiting on support to advise if anything can be done...

    Potentially have a brick on my hands here despite this being a known documented issue from multiple owners in the past...

    Fingers crossed. When it has been working, the touch controls and Robo Recall have been absolutely incredible.
