[Temporarily resolved] Can't get Pimax 4K to work with VEGA graphics


#1

Got my Pimax 4K several weeks ago but did not try it until now.

I just built a new computer based on Ryzen7 and Vega56 graphics. OS is Win10.

I installed the PiPlay software. During installation I got warning from my antivirus (BitDefender) but I authorized the installation to run. To be on the safe side I re-installed the PiPlay software again and now I got no indication of anything going wrong. I did get a warning that my system may not be fast enough but I’m guessing this is because your software is not updated since my hardware is much faster than the minimum requirements you state.

I started PiPlay and downloaded two videos to try as my first experiment with VR glasses. I tried starting them but I got no picture in the Pimax 4K. It was completely black. The light was blue and the PiPlay seemed to consider the P4K connected. I checked the graphics driver and all three screens were detected (my two normal screens running at 1920x1080 and the P4K). It was a bit strange that the P4K was set to 1280x720 and could not be set higher.

I fiddled around with the settings and I actually got the P4K to show some indication of actually being alive. The screen was still black but I could at least see it was turned on (slightly grey instead of completely black) and I could se a mesh of very small red dots. I could still not see any image when trying to play the videos through PiPlay. One of my screens shows a splash screen with instructions of how to end the playpack and I can hear the audio in the P4K headphones but no picture.

I rebooted my computer and now PiPlay no longer recognizes the P4K. The light on the P4K is no longer blue, it’s green and my graphics driver does not seem to recognize the P4K as a screen. I’ve tried unplugging and plugging in the P4K several times with not result. I can hear that Win10 does recognize that a new unit has been connected but nothing else. I tried uninstalling PiPlay to re-install it but when I try to re-install it I always get the message that the installation failed and the instruction to disable my anti-virus. I HAVE disabled every single function in my anti-virus and the only thing left is to uninstall it which should certainly not be necessary.

As it is I have not yet been able to get any kind of image through my P4K and now I can’t even install the PiPlay software. What’s wrong and how can I get it to work? This is certainly not giving me a good first impression!!!

The last thing that is shown in the progress bar during installation is “Installing AutoPlayer” and as soon as that shows up the installation fails. Don’t know if that is significant or not but I just thought I should mention it.


#3

The PiMax headset will show as a display when in video mode. In PiMax mode the headset will not be seen by the graphics control panel.

This may seem odd thing to ask. Have you tried the headset on? There is a sensor in the headset that detects if uts being worn.

Added pokes to your post.


#4

@MrOCM I suggest that you may uninstall K-lite decoder in Control Panel - Program, and then reinstall Piplay driver. Please also try to uninstall your GPU driver and then download and reinstall it manually. AMD driver: http://support.amd.com/en-us/download

Anyway, I would like to assist you remotely through Teamviewer software when you’re available.


#5

Not an odd question at all. It would be an easy mistake to make. However, I am constantly trying it on and taking it off (since I can’t see the screen when it’s on). At this point I can’t even get the software installed which is most likely not related to whether or not the P4K is on my head or not. :slight_smile:


#6

@Pimax-Support I will try to find K-lite decoder and uninstall it to see if this helps. I actually tried to find a way to uninstall my GPU driver yesterday but I couldn’t find a way to do it. I switched to Apple platform a number of years ago so Win10 is still a bit unfamiliar to me. I’m using Win7 at work on a daily basis but there is never any driver related tasks to handle. My VR computer is at home so I won’t be able to try anything at all until this evening at the earliest (it’s about 9AM where I am right now - GMT+1).

Unfamiliar with Teamviewer. I will look into it. Not sure if you will be available at the same time I will be able to access my computer (normally between 6-10PM GMT+1).

Have a similar issue with Vega 56 not working with pimax, it worked fine with my 480.

Can’t get pimax into direct mode, constantly connects in video.

It’s really bloody irritating.


#8

same symptomes here since i bought an VEGA 64, my Pimax 4 k refuses to show any Picture. Glad iam not hthe only one…


#9

@Pimax-Support I have now tried uninstalling the K-lite decoder and after that it was once again possible to complete the PiPlay installation. I then figured out (to my shame) that the GPU driver installer had a built-in uninstaller so I uninstalled the driver and re-installed it (naturally with a reboot after each step). The PiPlay software now recognizes that the P4K is connected by USB but it still considers the HDMI disconnected. I have tried unplugging one of my monitors to make sure there’s no limitation to the number of screens that can be connected but it did not make any difference. I also connected one of the screens through the HDMI port to make sure it works (my screens are normally both connected through DisplayPort) and there is nothing wrong with the HDMI port. The P4K is simply not recognized as connected through the HDMI port at all.

It is really strange because both the USB and the HDMI was recognized as connected when I connected it the first time. I just couldn’t get anything but a blank black screen. Now it’s not even possible to make it recognize that it’s connected.

Since this is a new computer there is always the possibility of starting all over again, to reformat the drives and install Win10 again. I would rather like to avoid that if possible though. It should not be necessary if the hardware and software for the P4K would actually work as it’s supposed to.

@MrOCM @pablosan @domrockt Hi guys, sorry for inconvenience. Last time, we submitted the same issue from VEGA 64 user to AMD side, but still no response yet.

Please go to Help page of Piplay interface to export logs to support@pimaxvr.com, it will be better for our further analysis, thanks.


#11

Hi @MrOCM , can we use Teamviewer together for this issue?


#12

Hi guys, @MrOCM @pablosan @domrockt

Sorry to keep you waiting.

Just now we got a response from AMD side and make a temporary solution as below:

  1. Download the firmware flash tool: [Release]Pimax 4K firmware
  2. Use the above tool to flash the special firmware into the headset, link at: https://mega.nz/#!NUoAFYpQ!L7Cq_hMIo_3IVkxwp_WsCQZZEFxzhb9XvXDCPxrKlXc

Please let me know if it is effective, thanks.

Hi guys,

I’ve now got connectivity with both headset and nolo. tracking is working (i used mirror mode in steamvr to check) but pimax screen is just lighting up grey, no pimax logo, no steam vr.

Is it possible the device is stuck in extend mode somehow instead of direct?


#14

What is the colour of the led on the top of the hmd?

Have you tried unplugging USB from HMD and plugging it back in… It fixes lots of those types of connection issues…

Make sure that steamvr and steam is closed then reset USB cable… Then start steam and steamvr again

@Pimax-Support Hi, same problem, upgraded to a Vega 64, LED gets either green or blue, but the screens stay dark(if i put my finger on the sensor, the backlight goes on) while piplay shows usb and hdmi connection, it never gets recogniced(in the device menu in the options). tried several usb-ports, un and reinstalling/plugging everything several times, now after 3 hours i tried the firmware update thing.
took me a while to find out that i had to put the files into the Runtime folder in the pimax folder to get it to start. started the upgrade program, got the hmd into dfu mode, but wether i click on upgrade or return from dfu mode a black window comes up and a error box that the application couldnt start correctly, error (0xc000007b)
i tried admin rights and all the compatibility settings, no luck… im at my witts end, i think i need help…
btw. i cant read the S/N on the headset, its totaly worn away, but the upgrade thing said 100 something, which i found weird, because judgeing by the stickers on the screenshots, i think it should be a 102 hmd?.. anyway can i turn the Pimax off while it is in DFU mode? or will that brick it?


#16

Hi, regarding firmware upgrade, it seemed that your PC lacks DFU driver. Please try this solution as below:

  1. Just quit Piplay (Don’t stop “PiServiceLauncher” Service in Task Manager).
  2. Drag the tool (https://mega.nz/#!wB5GDTTR!NnZn8qZF--kpU3Zz3qQOSGj5348ELg7Jw-diSmZWujw) to Piplay installation (C:\Program Files\Pimax\PiPlay2), and then use it to flash the firmware.
    Firmware downloading: [Release]Pimax 4K firmware

If you unplug the USB cable of the headset when it’s in DFU mode, the LED light may be extinguished (brick). You may press all three buttons on the headset, and then plug the USB cable, release Power button after 8 seconds, meanwhile keep pressing other 2 buttons, release middle button after 8s and keep pressing the last button in 8s, finally you should see the light is flickering, it means the headset enters to DFU (Firmware update) mode. If not, please operate above again. (Video tutorial: https://mega.nz/#!wJ40yRaS!-FF4rigkCTWwH79IXL2lg5lAOcGl0TcrnU0E7C3-32o)

@Pimax-Support Hi, i left the HMD running in DFU mode and the new firmwareflash tool worked fine. i installed the “spezial” firmware 1.0.0.65535 for Vega GPU from the post above.
sadly it doesnt seem to have changed anything… just a lot of endless flickering and not getting detected…
same with the firmware 248 and 251 for the S/N 100 series…
for fun i installed firmware 1.0.0.248 for the S/N 102 series and it get detected instantly, backlight turns on without putting my finger on the sensor like it used to. but the screens stay black no matter what i do…
ist there a new “spezial” Vega firmware for the 102 series?
also let me mention that windows seems to allways detect the HMD as a 1280x720 monitor? that doesnt seem right…


#18

Hi, thanks for your feedback. Our testing department is testing this issue in a new Vega card and will update the progress for you guys who met this issue soon.

Edit: The headset you use should be our BE version with 102xxx series number.

Edit 2: Now we get in touch with AMD side who basically locate the issue and we are doing together at present.


#19

@Pimax-Support hope we can get this fixed in a timely manner, im not keen on the idea of going back to my rift until my 8k arrives.
im out of ideas otherwise, so here are some Log Files in case they help:

Hi guys, how is it going?

Recently we made a special firmware for Vega users after discussing with AMD side, downloading link: https://mega.nz/#!cMBzXSJC!m_3HgHjSeYJNDhUg3Qnz5zYVVl57zKhCxU19NIhJO3g

Please be noted that it’s just a temporary firmware and we will release a normal one after discussing with AMD side again soon. Any feedback will be much appreciated.
