SteamVR Error 109/435

[тнє ѕнα∂σω ƒιgυяє]

I was playing VR earlier for about 2 hours, got off to let trackers and controllers charge, and then tried getting back on after 2 hours of them charging, and suddenly I get hit with the two errors in the title.

This isnt the first time it's happened either, it usually ends up going away after I attempt to play for a day or two. So I was curious if anyone has fixes or knows the cause. Thank you all for your time.

IDK. It's either on this list, or will be when you figure it out.

From what I've seen basically ignore the 109, it's common and the headset generally being finicky for whatever reason. Someone in this post chain https://steamcommunity.com/app/250820/discussions/0/1752394498611647895/ mentions doing an HMD reset (explained in there) and the other person mentions something I think gets over looked a lot, G-Sync and FreeSync don't like VR, if you have them running on your primary monitor you're going to run into issues.

Yes I had error 109, I fix it by disabling G-Sync in my case works 100% on launch. However it could work even with G-sync on but like 50% chance.

used the Steam Vr with my Pro and pro 2, first time i had the error 109 / 435.... thought it might be the cable. Tried it on my desktop and my laptop... same error. updated the video card drivers, could only get it to work in Disable Direct Display Mode
