This issue is similar but not the same as https://community.openmr.ai/t/newly-arrived-8kx-does-not-work-really-frustrated-now-working-with-desktop-rtx-card/38095 as I’m using a desktop PC (not a laptop) and direct DisplayPort cable (not an adapter).
I’ve spent at least 7 hours looking through multiple forums, reddit posts, and troubleshooting docs on the official site and have got nowhere. I’ve also created a ticket and have provided SN and Pitool log.
I have a new Pimax 8K X, first time plugging it in I was greeted with the “DP not connect” issue, did a quick google and found that it was an issue with old firmware. So I flashed to the 8KX firmware on the site (https://support.pimax.com/en/support/solutions/articles/60000691213-for-8kx) which left me with a white LED and no USB connection, with Windows saying it’s an unrecognized device and couldn’t install the drivers.
After trying out many different firmwares linked to on forum posts and on reddit, I’m still in the same position. The only firmware which gets me back to the “displayport not connected” issue is
P2_DEBUG_M270_t20210107171555_r99ad675 but then I do get Pitool telling me to update (which fails).
I’ve also tried replugging the cable going into the HMD, uninstalling my graphics drivers in safe mode as well as Pitool then reinstalling, reinstalling my USB controller drivers on the motherboard.
GPU: RTX 3090 (latest drivers)
RAM: 32GB DDR5
Pitool version: 220.127.116.115 (have also tried 272)
P2_DEBUG_M270_t20210107171555_r99ad675(this gets me back to DP not connected issue but with Pitool telling me to update, which fails)
I didn’t take a note of the original firmware on the device when I received it as I didn’t think I’d need to
Also, the SN sticker is very faded which doesn’t fill me with much confidence that this is a brand new device.
If anyone can give any advice or help whilst I wait for replies from support, that would be fantastic and much appreciated.
