Fullscreen 'gpu scaling' & 'Preserve aspect ratio' not working from 1200p to 1080p/720p

I want to have AMD force GPU scaling & preserve aspect ratio on my monitor (16:10, 1920x1200) so I don't get an ugly stretched game when i'm playing on full screen with a 16:9 aspect ratio (for making videos).

"Display scaling: Preserve aspect ratio" blatantly gets ignored for 1080p fullscreen and 720p fullscreen. But for some reason NOT for 1366x768, which is really close to 16:9. I suspect they hardcoded it for these standard HD resolutions.


Steps to reproduce it in Path of Exile:

- (have a 1920x1200 monitor & connected via HDMI to an Sapphire 280x or equivalent AMD video card)

- Download & install Path of Exile

- Add the profile and start the game with these settings:

- Run the game

- Change resolution to 1920x1080 & Fullscreen in the Path of Exile settings

- Observe that there is no letterboxing

- Change resolution to 1280x720 & Fullscreen in the Path of Exile settings

- Observe that there is no letterboxing (YET AGAIN)

- Change resolution to 1366x768 & Fullscreen in the Path of Exile settings

- Observe that there IS letterboxing/GPU Scaling and aspect ratio is being preserved.



Steps tried to fixing it:

- switch the desktop to 1080p with "Preserve aspect ratio" scaling prior to launching the game

No luck.

Here's what happens on my 1920x1200 monitor on 1080p desktop resolution with proper aspect ratio preserved.

As soon as i change the game to full screen (with 'preserve aspect ratio' in the game profile, display settings AND global profile) this happens.


Using these Crimson Display Settings and these Windows 10 Display Settings.


- adding a custom resolution for 1920x1080 or 1280x720 and trying it with that

Did not work; gave this warning message and when you decide to continue it still ignores preserve aspect ratio. Funnily enough it does this ONLY with 720p and 1080p; any other 16:9 aspect ratio resolution (like 1792x1008 or 1600x900 works fine).


- some suggested changing settings for your monitor to fill to aspect ratio

There are no such settings on this Syncmaster 2693HM. Furthermore considering it does scale it correctly on custom 16:9 resolutions OTHER than 1080p or 720p, it suggests it's not a monitor issue.
