I'm having some trouble understanding how to use lower resolutions for playing games while maintaining my native resolution. The native resolution is 1080p which uses a custom aspect ratio for it to fit my display but that option does not exist for the 720p and 1600x900 resolutions that I want to use and using either of these resolutions with any of the scaling options that are available leaves me with a resolution that is either too large for the display or contains black borders. I have some games that I would like to run at 720p for the performance boost and I would prefer to use a 1600x900 resolution for some other games as the GUI is too small for 1080p but if I maintain my native 1080p resolution and change the in-games settings to that of which I would prefer the results are the same. The resolution over stretches the display or it appears centred with a border. Can someone expalin to me how I can maintain my 1080p profile while being able to use lower resolutions that fit the screen for gaming?
I tried a method from another discussion of changing the resolution via windows to a lower one then changing the scaling options from the Intel panel to 'scale to fit' with both my preferred gaming resolution profiles then changing back to the native profile but this didn't seem to produce any results. In-game the resolution continues to over stretch the display. I had to do something similar on my previous display which I ran at 1600x900 as the native profile , game, resolutwhich works fine but the same can't be said for this Toshiba 32".
