2) While on battery, there seems to be no way to turn off the auto-dim or auto-contrast. I've tried the adaptive brightness settings in power options, uninstalling Splendid, disabling Sensor services.
Any thoughts?

I did check the BIOS and nothing
Honestly, I really wish I had known this as I think it is a deal breaker for me too...
Going to play some more tonight and unless I can find a solution to either Optimus or the autobrightness problem, I'll setup the RMA tomorrow.

Nyceis, you might want to give yourself the full return time to figure this out, and not just turn it around so quickly.
This is a new laptop and problems take time to solve. Once you work out the auto-brightness problem, maybe a few tests on battery will work well enough for you to keep the G750JY - it seems like a great laptop 🙂
There was a problem with people that did a Microsoft install of Windows, they couldn't get rid of the auto-contrast / brightness, did you reload the OS from scratch?
You should know there are people that still haven't gotten it working right on their G750, but fortunately I have. I can list the things I did, the 2 main ones are:
Uninstall Power4Gear. It puts in it's own Power Plans over yours when you unplug and plug back in - switching from AC to battery triggers Power4Gear to put in it's own Power Plans. You can tune it's Power Plans too, but for some reason they revert back to their own settings later.
You can verify this by looking at the settings before after removing power and re-connecting power. PC Settings in Windows 8.1 GUI => PC and Devices => Power and Sleep --> Adjust my display brightness automatically will be there if enabled, and won't be there if it isn't. I don't see that option, as I set it in my Power Plan Advanced Features.
Set the Display settings as you did, but also take the precaution of setting the Display Brightness at the same value for all settings - that way if it switches it won't be perceptible
My AUO screen is very bright, and I can only use it at 100% outdoors. 80% seems to be the best for indoor use.
There is also an Nvidia setting that can get enabled for Dynamic Contrast Enhancement, disable it, or do as I do and don't use the Nvidia settings - I only enabled it briefly to show the option, it is for video only, but some complained about it:
There are lots of links for help, this one is nicely detailed:
Adaptive Brightness - Turn On or Off in Windows 8

Good thing you don't have Optimus, then you would also need to do the Intel settings 🙂
Please let us know if this fixes it, otherwise if those aren't enough, and they should be, we can still try other things in the registry. Rebooting, maybe even powering off, in between helps too.
Interacting on notebookreview site, re-posting here.
Nyceis, weird, there is no Power4Gear installed? I wonder if Asus renamed it. That's nice to know it is gone
Which Power Plan are you using for AC and for Battery? I use Balanced for both, but you could have Battery Saver power plan enabled when on Power, so you need to set the Advanced settings for that Power Plan as well. Might as well set all of the Power Plans to the same settings...for testing.
Can you please post the Asus installed apps from Programs and Features? They may be different. Is there an Intel Display related install, anything from Intel?
Here is what I have uninstalled: P4G, Splendid, Asus Live, Asus Vibe, Asus DVD (I have Cyberlink PowerDVD Ultimate 14), Gaming Mouse, Cyberlink 2 Go.
Here is what I have left installed for the OS from the original Asus Build OS:
I have some upgrades for drivers ready to install, so those aren't absolutely the newest.
What does your G751 have left installed, and what did you remove?
Did you try setting the brightness manually with Fn+F6 *before* and *after* auto-brightness dims it?
I have heard of dual settings for the Fn+F6/F5 setting based on auto brightness - it has been a while since I fixed it for myself. You could also try setting the brightness via the slider for the Active Power Plan after auto-brightness takes effect.

This is the factory install so far; won't reinstall until I decide to keep
There is no Power4Gear in the Add/Remove Programs. I did try that setting in nvidia too. No difference. I set brightness to max in all plans and all settings, no luck.
Already disabled adaptive brightness in power settings.
Honestly, I would actually probably call it dynamic contrast. The contrast gets crazy when the screen is dark on battery and then goes back to normal with a light colored screen.

Same issue as nyceis w/ the annoying auto contrast adjustment when on battery. The screen seems to auto adjust the contrast or "White level" depending on how much white is displayed on the screen. If there is no white, then it cranks the brightness of the whites way down so there is virtually no contrast. If there is some white, it up's the whites a bit so they're grayish. If there is a lot of white on the screen then it cranks it all the way up. How is one supposed to get any accurate color/contrast or black/white levels when working with any video/photos/digital paint with this behavior?
I only realized exactly what this annoying behavior was when I was testing the flickering on my screen by tiling this inversion pattern image as my desktop background:
When there is only the desktop, you can see all the icon text and everything else get very dim. When different windows of different sizes are opened, the annoying autocontrast behavior can be observed. And the brighter the whites, the more intensely visible the flickering is.
Tried all the solutions listed above to no avail =(

Did you try disabling adaptive brightness ( auto-brightness ) and set the brightness values all the same for both AC and Battery in your current Power Plan?
