Changing saturation brightness contrast hue - How?

Hi, as annoying as extended mode was, we were able to use the nvidia control panel to manipulate the way it all looked.

This was fab, especially for movies.

Unfortunately now, the unified direct mode that it seems to be using, won't allow you to manipulate colours through the control panel because the panel doesn't recognize the rift in anything but extended mode.

I've read about 0.7 being brighter than the previous ones but i couldn't find any of the referred-to file headers to fix the problem.

My question;
Is there a way to manipulate the colour/contrast/brightness/gamma in this new direct mode?

Cant these hues or r,g,b be adjusted via a video player so that it appears as intended on the rift?

Not through any that I'm aware of.

Media Player Classic seems to have a considerable amount of features and filters to adjust these type of settings.  Not tried them myself but together with some desktop based viewers for VR it should do what you want it to do.

Hard to believe this is not available in the Rift. Utterly unacceptable! At least give us Brightness/Contrast settings geez!

This is another "can of worms topic" I am afraid.

Someone here on the forum actually explained it nicely WHY there is no need for a NV control panel for the Rift. The reason is that this is not necessary since Rifts (should) provide the same experience "out of the box" across ALL USERS, unlike as with monitors. Monitors can differ in how they display stuff, and most importantly, viewing environment differ, which makes a control panel for monitors necessary.

These problems don't (normally!) exist on the Rift, means each "experience" by each Rift user is pretty much the same..respective SHOULD be the same. Optimally exactly how the makers of a game/app etc. designed it.

A control panel would give people the (undesired!) option to change an experience (game, app, etc.) in a way that was not intended by the devs, so ultimately it would introduce more problems than it would solve.

For me, there is however ONE MAJOR reason why I'd want such a control panel. Not as a way to "tweak" the image (because this is solely on devs, and no-one else how their game/app will come across) - but because of inconsistencies with Nvidia software and NV control panel. For example the problem that it sometimes doesn't initialize correctly and sends "limited dynamic range" to the HDMI output. So really only for debugging and testing purposes.

That the Rift is "plug-in" and go, without any fiddling and settings needed...is actually a positive thing and not a negative.

Also:

The issue with being able to adjust brightness, contrast and in particular color saturation (digital vibrance etc.) is MORE COMPLEX on the Rift as it may seem.

Why?

For example, the Rift compensates for distortion and chromatic aberration by intentionally sending out a "pre-distorted" image, eg. it creates artificial chromatic aberration ("rainbows") which means it relies on colors to do this. So reducing color intensity would not just mean an image with less colors, it also makes the image on the Rift blurry and more distorted, means it is a significant thing when it comes to image quality, WAY more significant than with a normal monitor.

The way how the Rift outputs an image, this includes colors, gamma, contrast etc. I am sure is carefully considered so it gives the best image overall. This is why "normal people" should not mess with those settings even if at first they seem trivial. It's simply not as easy as with a monitor.

That may sound nice in theory, but I don't think this approach works very well with such a large variety of applications. Personally, I'm extremely unhappy with the appearance of night environments in the Rift. I find them way too bright and grey-ish.

In Elite Dangerous for example, it's not a problem. There is a gamma slider in the game itself, and it looks fine on a lower setting. But other applications don't have such a slider. In FSX or Project Cars, the night environments look awful. So why can't there be a setting in Home for these cases? There could be basic and advanced settings. Basic for most people and when you click on advanced, there could be a warning message, something like "adjust at your own risk..", but at least the option should be there IMO.

MAYBE you have the problem that your Nvidia (?) driver (because of the mentioned issue) doesn't send the correct dynamic range...eg. "blacks are not black". (You can check this plugging a monitor into the HDMI where your Rift normally is connected, bring up NV control panel, click "resolution" and check whether "output dynamic range" is set to FULL. It has a habit to reset to "limit", especially after a new driver install which results in crappy blacks. THIS is exactly the reason I want a control panel since replugging the Rift is not exactly practicable.

By the way you mean FSX as in FSX, the flight sim?

STILL, ultimately and assuming that your NV driver etc. is all correct, getting a correct image would not be OUR job by fiddling with settings, but the devs jobs obviously. This is why normally such settings shouldn't be needed. If a game/scene etc. looks crap...it's the fault of those who made the game and noone elses. Simple as that.

Yep, FSX, the flight sim. Thank you very much for the hint about the color range. I plugged in a TV and output dynamic range at the HDMI was indeed set to limited. I changed it to full dynamic range and reconnected the Rift. I think there may even be a slight improvement, but in general, the sim is still WAY too bright.

In that particular case, I don't even blame the devs. I'm sure they didn't imagine in their wildest dreams that their version of the sim would be used in VR 10 years later.

small update
Deo VR player (video player) has contrast brightness saturation controls which rival madVR's shaders.
still no hue slider.
https://deovr.com/

edit;
I sent a request in for a hue slider with the `post-production orange tint` as a rationale
`Thank you for feature request. I have forwarded it on to the developer, where it will be added to the roadmap. 20.01.2017, 12:40, "DeoVR" <support@deovr.com>`

edit;
9 months on, no change.
