CV1 Black levels finally fixed for me! Weird solution.

Fact so far this isn't an ED issue it's a rift issue.
We should honestly petition them to implement some basic calibration tools so we can adjust gamma, brightness and contrast ourself.

No two hmd's (and quite frankly no two panels) are the same.

NVidia mis-sets the dynamic range for the port the rift is on (sometimes).

If you fresh install the drivers, or move the rift, or some other things this sometimes gets NVidia to change to the correct full-range.

Or you can just manually change it with a script like this: http://blog.metaclassofnil.com/?p=83

I recently noticed the "sometimes" part.. for me, switching back to rgb and then back to 422 again brings it back for awhile.

I did what the op suggested, but to me there was no difference. Nebulae's still suck and overall smearing in space still awful.
Will try using display port adapter next.

What level of gamma do you set IG on the scroll bar ?

I tried from minimum to maximum. Nebulea's look very strange. Like cheap cartoon. Did not have this issue with old pre-release oculus drivers(0.6 runtime).
Yes I'm using DK2 but had burrowed a CV1 from someone and found it to be same issue (at least on one eye)

Did you set the NVidia DR on your port?

I can replicate this effect on my monitor by taking the oculus off my head and letting it go to auto standby. My monitor is an old DVI number that was lying around in work, running off a DP to DVI adaptor. Soon as I take the rift off, the display goes all horrible and desaturated. If I put it back on my head and it wakes up the monitor goes back to full-on vibrant mode. I mention this cos it seems related.

I'm pretty sure the reason your Oculus is going "horrible and desaturated" is because you are more than likely out of range of the sensor. This happens to me if I turn round 180 degrees in the rift. (Even though I thought that the rift was full 360 experience).

Although since Oculus went live my DK2 experience has improved, with better framerates and little judder one thing I miss the most is the vibrance, it feels washed out.
Had a look at some of the suggestions on this thread but still feel frustrated as I don't know what I'm doing wrong, a little help would be greatly appreciated here.

My set up is as follows:

VGA from monitor to DVI adapter on GTX 970
HDMI from Oculus to HDMI on GTX 970

Having read this thread I bought a HDMI to DVI adapter to plug the rift into, instead of it going in to HDMI port on GTX 970 as I believed I could then change the colour to full range, but I still can only see my VGA connection in Nvidia Control Panel so cant set the colour range for Oculus.

What am I doing wrong?

EDIT - I seem to have bought a 1080p adapter and not DP1.2 2k/4k

before I do though, will i still need to be able to change the colour range because I dont see that option - is it because my monitor cable is VGA? If so no point in buying the adapter

Thanks in advance

Cmdr Spencer you may need a monitor with a HDMI connection for it to be recognised in the Nvidia Control Panel to show the full colour options, I have the same problem. Hoping to 'nick' my son's monitor when he goes back to University.

its got a DVI-D port in the back too so I guess connecting this may give me the options for full colour, instead of VGA-DVI converter?

Anyone else getting purple strobing lights on the CV1 screens when they connect via an active HDMI to DP adaptor? Using a 4K one, should it be 2K/4K? Any ideas what's causing this?

Sorry for the delay, no it doesn't work for me. I believe the Nvidia Control Panel is 'looking' for a TV via HDMI socket. DVI and VGA are treated as monitor sockets and it ignores the Full HD colour options.

Well I've got my sons TV which is full HD with a HDMI socket and have the DisplayPort adapter from Amazon. The options in Nvidia Control Panel do now show up for me thanks to the connected TV. It 'appears' the text is slightly sharper to read and the colours maybe a fraction more vibrant but to be honest they have always seemed good to begin with. The colour banding though has not changed at all which is really disappointing. For a couple of hours I went through various options swapping ports and selecting RGB then YCrbCr422 and performed a clean install of the drivers, no change. So for me this hasn't worked.

Pretty sure you need to plug a monitor into the HDMI port, set up the Full Colour Range options (and calibrate the display etc)
Then unplug the monitor and plug in the Rift/Vive. The Rift should then adopt the new settings (settings appear port-specific, not monitor-specific).

However, I got good results from simply running the display calibration/gamma settings again. My gamma was a bit too high so those near-blacks were too visible; it was much reduced once I'd re-calibrated.
