CV1 view not level - help identifying if image is not parallel to ground

Tech Support

It's a couple of months I have the suspect that the image projected by my rift is not level to the ground, I think it's a bit tilted to the right (2-3 deg). It's just a suspect I have and I would like to verify it, maybe taking a screenshot like this [post] (https://www.reddit.com/r/oculus/comments/4cclt8/oculus_cv1_sensor_miscalibration_persistently_not/) suggests.

How can I set the mirrored image on my desktop screen to be "double" (as 2 images, 1 per eye - like image in the linked post) and not single, so to be able to verify alignment/tilt? For example, when playing iracing, the mirrored image on the screen is single, and I would like to have 2 to verify if the view is level.

Did any of you successfully solved such tilt/image not level to ground? I saw Oculus support sends a calibration tool for such problems, does it work?

Thank you for your help.

I used the Oculus calibration tool to fix this on a couple of headsets. Works like a charm. The IMU is sensitive to temperature changes, so shipping it across the word can throw it out of whack. I suspect many people just don't notice. It would be great it this was just available to download as its not rocket science to calibrate.

The calibration tool requires you turn your Rift upside down and lay it on a completely level surface, unplugged and let your Rift cool down fully (for hours). Then run the calibration without touching moving walking or even breathing near the Rift ;) .

Its the movement across the range of temperatures as the Rift heats up that allows the calibration to work. So doing this in the evening in a cool room would be the best.

Found the calibration tool at vrheads, do you think it'd work or shall I submit a ticket and wait for the support version link? edit: just submitted a ticket

Could work but probably best to get the most up to date version.

I'm so glad I ran across this. I've always felt like my rift display was just very slighty crooked. I thought I was going crazy. Gonna try recalibrating.

I opened a ticket on support and for the time being they asked me to reinstall the oculus sw to recalibrate it but this did not work. Now they are asking me to run Oculus Log Gatherer utility, will do as soon as I get back home from work. Support is very kind and responsive, I really hope they'll figure out a solution.

I've noticed this issue on my 3-sensor setup, and I was curious if it was due to how my cameras are mounted since they are canted a little. However, when I went to the Oculus showcase and booth at GDC, I noticed the tilt on their 2-sensor forward-facing setups, too.

Yeah I've always had the same since I got my CV1 in October. Was the same for 1, 2 and 3 sensor setups. It only happens in Home, though, so it's not really a big deal for me. If you press the 'Oculus' button to bring up the white space, that always looks level for me even when Home isn't, so it seems to be calibrated separately.

Home to me looks straight and parallel to ground, it's iracing and minecraft that seem tilted a bit

I'm pretty sure I have the the same since the beginning. Never bothered to adjust it, but would be nice. The procedure sounds annoying though :)
