PiMax 4K solid green light, no sound, blank screen


@mynamesriz sure,waiting for your updates.


Ok, this is the moment I’ve been waiting for.
The headset worked on the gtx 1080 without any issues.

So it looks like something on my laptop is causing the issue.

From here I’m going to try one more thing, I’m going to re-image my laptop. If that doesn’t work then my brother-in-law said he’ll buy it of me. :slight_smile:

Assetto Corsa with a Logitech g920 was incredibly immersive.

Thanks everyone for all your help so far. I really appreciate it.


@mynamesriz you are always welcome, thanks for support Pimax 4K.


Hi All,
Here’s my update after installing a fresh windows image on another harddrive…still the same. There is some fundamental incompatibility between my laptop and the PiMax 4K, Which is weird IMO.

I wonder if the HDMI port is struggling to provide enough power? it says HDMI is connected but the LED is green which is a HDMI connection issue. I wonder whether it’s worth trying a powered HDMI splitter or something. I’m really grasping at straws now.

Honestly I’m really disappointed, the headset is awesome and to be honest after seeing it in action first hand I don’t think I could settle for a lower resolution screen. I think my only option at this point would be to get an external GPU but that seems like a lot of expense to get a VR headset working. :frowning2:


It might be due to being an Optimus Laptop.

However while generally not reccommended. I would try a powered USB hub as often laptop usb ports don’t often output enough power.

@VRGIMP27 i think may have some ideas as well.


even if it is an Optimus laptop extended mode should work shouldn’t it?

Also I just tried a powered USB hub before writing my last post too but still got the same issue.
@vrgimp27 any ideas?



1st, is it an optimus laptop? If it is, I would try reddit Oculus for a detailed set of options for fixing it. What GPU is it running?


Yes it’s an Optimus laptop gtx 1060 6gb.
I’ll take a look at the link you shared.
