What is making it so I can't rotate my monitor

Most likely it would be cool if I could rotate one of my monitors. I know that Windows makes this an option.

Windows 8.1 version 64 bit. ASUS S200E. Intel Graphics HD 4000

When I go into the setup, it is not an option:



It displayed once for something else, but it was greyed out:



A search online suggested that I could go into the intel monitor options and change it in there, but that selection was not on my screen, either.



When I searched I found that other people had the same issue with this graphics card, and they were instructed to download the most recent drivers. I did that, and when I tried to install them it said they were not validated on this computer. I looked and found that manufacturers can build their computers so that you can install drivers from them and not from anyone else, and apparently I can only use ASUS drivers and not intel drivers.



A few individuals suggested using the keyboard commands, ctrl and alt with arrow, but that didn't work either.

I guess my only option is to completely uninstall the Asus monitor device and reinstall the intel ones? But I'm afraid that if I do that I will not get them installed correctly and won't have a way to get it back.

A few sites suggested making some registry modifications but I'm not sure if that would work.

Is it the same if you try option two of this tutorial?

Yeah, it's greyed out there, too.

I'm at a loss, there must be a reason it's not letting you, I don't know what that could be though. Sorry, maybe someone else will have something.

A few more things I tried that did not work

I am unable to run a second display in portrait mode (off HD... - Page 3 - HP Support Forum - 1643217

On another page I found the following instructions,

Holy crap, I got it to work! I'm not a tech guy, but I've been frustrated with this for a year and a half now so I decided to risk it and went to the registry

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\4D36E968-E325-11CE-BFC1-08002BE10318\0001

and changed all of the following values from 0 to 1(after backing the registry up)

Display1_EnableIndependentRotation
Display1_IndependentRotation
Display1_PortraitMode
Display1_RotationCaps
Display2_PortraitMode
Display2_RotationCaps

I don't know if all of these were necessary but it works now.

The method described there did not work for this computer.

The next reply said this:

I followed ndHP's suggestion about the registers but I also had to change a few more before it worked:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\4D36E968-E325-11CE-BFC1-08002BE10318\0001

Display1_EnableIndependentRotation =1
Display1_IndependentRotation =1
Display1_PortraitMode =1
Display1_RotationCaps =1
Display2_PortraitMode =1
Display2_RotationCaps =1

After doing the changes he suggested I was able to see the option for "Orientation" on the windows display settings but I wasn't able to save the changes.

Then I changed:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\4D36E968-E325-11CE-BFC1-08002BE10318\0001


Display1_DisableAsyncFlips = 0 (was 1)
Display1_RotationCaps = 7
Display2_RotationCaps = 7

VICTORY! Thank you all for your help in this area!

Again, doing that did not work for me.

Oddly enough, my Display_RotationCaps were 7 to begin with.

Checking the Intel options I found this
