Rotate one duplicated screen without rotating the other Windows 8

Question

I need to duplicate my desktop to show a video on two screens however the second one is rotated at an angle of 90 degrees.

I'm aware when you duplicate the screen any rotations are applied to both screens is there a way for this not to happen.

I've tried writing some C++ to change it however as soon as I apply the rotation to the second screen it forces the settings for the first screen to change as well. I'm considering write a program to give me the functionality I need however I need this today or tomorrow at the latest so there isn't really much time.

Any help would be appreciated

Solution 1

It is not possible to rotate one screen and not the other while in duplicate mode. If you make it so that one monitor is an extended screen it will rotate by itself.

Alternatively your videoplayer may have the option to rotate the screen 90°. I know for example that both VLC media player and Media Player Classic from the k-lite codec pack can do this. Note that rotating the video itself will rotate it at both screens too. Thats just how duplicate works.

Solution 2

I'm years late to the party, but hopefully for others looking for this info it'll still be of use.

Achieving this in Windows 10 (might work on Windows 8.1 also, don't know) is easy, but not obvious.

First, extend your desktop to the monitor you wish to adjust. Second, set the orientation you want on that monitor. Third, change the 'extend' mode to 'duplicate' instead.

Now, your image will be properly oriented on the other display.

I feared as much, looks like the easiest option will be to just use two computers, one for pc display one for projector display :(

or not rotate the 2nd screen, or rotate the first one too.

No I need one rotated and one not, the first feed is for the user the second screen is mounted sidewards (can't change that) for an audience, so one needs to be rotated and the other not

This does not answer the question. OP notes his screens are Duplicate, while your answer admits it is only for Extended mode.

Please read the question again carefully. Your answer does not answer the original question.

Confirmed! Works in win10

Doesn't work for me on win 10 - i feel like a fool fighting with it for hours... :( I'm not an Apple fanboy but there it took 30sec - set separate orientation for each screen and add mirror check. Unfortunately I need to achieve it on Win 10...

This doesn't work for me either. You can extend it in the correct rotation, but not duplicate AND have it in the correct rotation.
