Is there any way to lower the gamma on the Intel graphics with the latest driver package (263.08)? Whenever I switch to the Intel chip the gamma goes way up and everything looks washed out and looks like garbage. The intel tool won't go lower than 1.0, at least on this version. Is there a registry setting somewhere that I can manually set it lower?
Thanks!

Tried resetting your intel driver settings to default?
-
Is there a specific process I need to do that?
I've tried going into graphical properties and hitting the "restore defaults" button under color scheme, and I'm already on the default settings there anyway.
I've also uninstalled and reinstalled, including using driver sweeper. -
This might sound dumb but have to ask:
a) are you on batt power? Plugged in? I was only switching if planning to be mobile for a while or lazy to dig up the cord. That is, I was always changing power status when switching vid.
b) double check screen brightness settings anyway in the power plan selection page.
Im on dedicated nvidia at the moment or I would try duplicating your issue. -
a.) Battery or AC power is the same. Intel graphics gamma is just too high.
b.) Brightness isn't the cause, its clearly gamma. In the Windows color calibration you can see the gamma just looks way too high. If I lower it I can make it better but even on the lowest setting in windows color calibration its still a bit high. Again, only on intel graphics. I'd use that but every time I reboot the computer it forgets the color calibration settings.
Additional info - when I reboot the computer with nvidia graphics on, then switch to intel, the gamma is fine until I put the computer to sleep. Once the computer wakes up again the gamma on intel is overblown again. Its almost as if it's loading some screwed up profile. If I boot the computer with intel graphics on the gamma defaults to too high.
It clearly happens after windows loads some sort of color or ICC profile because the screen blinks for a second then I get the washed out too high gamma.
Also, I didn't have this problem before I had the panel replaced due to the hinge problem. Once the tech replaced the panel the first thing I noticed was the gamma on the new screen was way too high. I asked him about it but he said it looked fine to him. I never checked what panel I had initially but the one I have is the SEC5441 (samsung?). I can't seem to find a color profile for this screen either. -
I'm experiencing something similar if not identical (only using the intel graphics). Colors and details often get really washed out, changing settings in the intel options doesn't help much.
Problem is not present using nvidia drivers/graphics. -
Is this a setting avail in regedit?
-
Apparently the control panel for the more recent Intel graphics allow you to set Gamma lower than 1.0 (should be .8 or .9 for this lcd panel), but we're stuck with the outdated intel drivers in the current R1 release drivers.

IIRC, this happened to me when I first got my m11x, and the answer was something about the power-saving settings in the intel control panel. I'll have to try and remember what it was.
-
You may be on to something there. I went into the control panel and when the intel gamma is fine I have a power options button on the display control tab, but when the gamma is screwed up the power options button is GONE!
-
hmm ive noticed that too, I thought it was for saving battery life lol
-
Yeah that's it.... the intel power saving technology checkbox... disable that and your gamma should be fine once you set it via the ICC tool.
Something about how the 'power saving' changes the display's brightness and contrast depending on what's being displayed and not what you set it to when in "power saving" mode. Nice huh? -
Oh, and this drove me crazy for the first few weeks of my m11x ownership. I couldn't see the control panel right now on my m11 since i'm on nvidia graphics but i did find this nifty article which might be of interest:

Fixed.
God... what a ing terrible "feature". For a while I thought my eyes had their life-essence sucked out of them or something.
Anyone know if there's anything else I should change around these options that will help me keep my sanity? -
Yeah thanks flanders! That "feature" is what was causing the screwed up gamma. Left everything else in there on default and its fine now, with one exception.
I ran the color calibration tool in windows, but then once you run the tool you need to specify the color profile it creates as your system default, so run the color calibration tool once to create a new profile, then go to color management and under the advanced tab change the Device Profile to the "sRGB display profile with display hardware data derived from color calibration" and make it the default so it gets applied next time you reboot windows. Gamma was still a bit on the high side, so I lowered it in my calibration and my graphics are now consistent between intel & nvidia. -
but disabling this does actually gives you less battery life?

Gamma below 1.0 on Intel graphics? M11x R1
