Reverb G2 - Flickering

[ElSakapov]

 Hi,

I noticed what I would describe as flickering/strobing around the peripheral. I'm seeing the same in SteamVR. Video through the lens included.

The issue appears 2 weeks ago.

I know, I'm not alone with this problem (e.g : https://www.reddit.com/r/HPReverb/comments/k6ym4c/reverb_g2_flickering_on_edge/)

I tried to rollback nvidia drivers, Win10 update.

I suspect : 

- a power unit problem

or

- a software sh**** driver

- or a hardware problem

Can you help me ?

Try lowering your WMR settings in Windows from 90Hz to 60 Hz to see if it goes away.

Start, settings, Control Panel, Mixed Reality, Click "Headset Display" on the left side of the screen, under "Experience Options" on the right change it to 60Hz.

Reboot and test your headset again.

Another thing you can try is placing a ferrite core ring on the power cable to suppress EMI noise interference which may resolve your problem.

Something like this ..

The through the lens videos you see online are not a good indicator of an issue  because the flickering you see there is most likely caused by the difference in the cameras shutter speed. Usually they use a cell cam to avoid paying for a high end camera that would avoid the flickers in their videos.

THIS IS NOT SPAM, KINDLY DO NOT REMOVE.

Hi,

Tks, I already tried to lower the frequencies > no change at all.

I tried to unpluged every power unit around me, etc.....no changes.

Did you try plugging the headset to a completely different outlet not associated with current one ?

Could be power line interference, something magnetic near by  or maybe even a wi-fi signal.

[ElSakapov]

Yep, I tried also a different outlet....still flikering, lower than 3 days ago but not as good as i expect.

Impossible to join HP Support to signal the issue....rrrr

[MYNY]

Are you next to a kitchen ? Refrigerators can cause interference. It tends to kill my wi-fi signal at home.

If you have neighbors nearby, especially in an apartment building it can cause issues if their transmission is strong. Shoot maybe a satellite t.v dish.

You are making me think outside the box .. lol

[ElSakapov]

XD, I'm thinking out ouf the box too....^^

And no, I'm in a house, first floor, no fridge full of beer close to my desk....

Tks for your time 😉

I have the same problem, it started yesterday - i have the G2 since around two months and everything was fine before. I tried the G2 on another PC with a fresh installation of WMR - the same issue, it's definitely a hardware issue. I also have a G1 and tried - no flicker on 90hz on the same two PCs. The flicker feels a bit like the low persistance flicker of the 60hz mode, but a bit less annoying. 60HZ mode is unusable with heavy flicker on G2, it was less on the G1 but still hard to  live with it.

Did you contact the support for an exchange?

The only non-hardware issue I could imagine is that the Reverb thinks it is in 90hz mode but the black frame insertion of the low persistance mode is set to 60hz. That whould explain why the 60hz mode feels like ~30HZ flicker now...

You know what.....the problem disapeared himself today.....

A thing I noticed, I keept it powered, no unplugged the power unit. The little black box stayed a bit warm, maybe un component is in better shape when warm for a while ??

I have to contact a hotline, unavaible (I'm in France).....for now, no success in support contact.
