Hey, thanks. :D
I don't know if it's because of your headphone trick, but the distortion has decreased lately. I'm happy now. :3

-plays Resident Evil 4 in stereo-

Thanks everyone <3

I want to tell everybody who still have problems with black dot's and screen distortion issues, that suddenly for myself I found the solution for this problem - I simply detached VR920 headphones.
It's sound crazy, but it's actually works!

I've tried two times for 3 and 3.5 hours of non-stop gaming (yesterday and today), with 1024 x 768 resolution, stereo and head-tracking and have no issues at all! :)
Now my VR920 works flawlessly, no distortion, no black dot's! :D

Please [b]try this out[/b], maybe this will help you too - just detach your VR920 headphones like in manual, and use your own sound-system.
Will be interesting to know, if this helps somebody, maybe this is common issue?

[i]P.S. Seems that with detaching headphones built-in sound-card go off.[/i]

I've put my computer on the other side of the house and plugged in the VR920, and as expected, it worked a lot better. (Keeping it there is not an option, though, I'd like to play games in my own room:D)

Trust me on this, it's not my hardware :p

Do you and your friend have different video cards?
Are you using the same machine to test in your two rooms? If not try the problematic machine in the other room...
Different monitor?
Basically what all is different between locations that work and that don't?

Can you post your dxdiag info?

Thanks for the link, but it didn't help much ]:
There are no wifi/bluetooth devices in my room, and my internet adapter is a USB Device that's located several meters outside my room.

Also, maybe this is any help: The distortion gets really [i]really[/i] bad when 3D is enabled. when I play in 2D, it's not that bad.

Could be an issue like this: http://www.frihost.com/forums/vt-87734.html

Or it could be a cell phone in the room, or maybe even a close wi-fi router

You could try attaching a ferrite bead rated for VGA, they're the heavy plastic beads on the ends of each side of some VGA cables that help absorb higher frequency EMI picked up on the cable from other devices.

Back with an update, here!

I've managed to get a replacement for my VR920, because it was completely broken. A week or two ago, I received my new unit, and it's working better than before, but the distortion problem [i]still[/i] isn't completely fixed.

But, I've tried hooking up my VR920 at my friends' houses, and it works just fine there, no distortion whatsoever. I also tried it on the other side of my house, and the screen appeared to be much clearer as well.

Naturally, I thought it was my computer, so I went out and bought a completely new one. (I needed a new one badly anyway:hehe:)
But alas, the distortion persists!

So I've come to the conclusion that [i]something[/i] in my room is interfering with the VR920's image, but I have absolutely no clue what it could be.

I've unplugged every single electronic device in my room, I tried plugging in my pc into a different socket, and I tried having only the VR920 as my monitor, but nothing works.

I'm thinking it's magnetic waves in my house or something, but how can I shield my unit from that? I noticed the VR920's cable is a lot thinner than regular VGA Cables, so I'm almost entirely sure I should isolate it somehow, but I don't know how.

Can anyone help me with this?

Try on another PC to be sure it's glasses wrong, not ur PC software/hardware.

Uhm... I sent my VR away for repairs, got it back yesterday, was overjoyed, but also disappointed.
The problem still exists, and on top of that, I get blue screens at random moments.

What have you done? D:

@Steffen: if you play with your cables, and that doesn't do it for you, send me an email, and we'll get you taken care of.

Maybe your VGA cable is near to power-cable of your PC?
Moving theese cables in different directions from each other, helped me to improve picture quality long ago.

Hey there,

Since recently, my VR920's screens have been getting distorted each time I use them.
After only 15 minutes or so, horizontal lines start appearing. (They 'move', they don't just stay still)

This is really bothersome, because it's a real immersion-killer.
After having the VR920 plugged in for an hour, the screen quality got really bad and I just can't play with it anymore because of this.

I tried checking my VGA cable, but it seemed fine, so I have no idea what the problem could be. (A friend of mine said something's probably interfering with the signal, but I wouldn't know what could be)

Thanks in advance ;D
