Technically 1440p is 16:9. I do not see any aspect ratio selection options in my monitors menus. I will check the manual though and see if anything is mentioned. Im no video or FPGA engineer, but I would assume that in order to properly display any 4:3 image in a 16:9 resolution, the RT5X Pro (or any scaler for that matter) would have to draw the pixels outside of the 4:3 game area as black (or some other uniform color). The RT5X Pro appears to do that properly and switch between 16:9 and 4:3 sampling modes in some output resolutions and does not work properly in others.bobrocks95 wrote:Would not be surprised if the monitor is seeing a 1440p input and forcing it to display in 16:9- see if there are any aspect ratio controls on the display itself. I don't see how the input sampling would affect the output resolution but maybe mike can say something there.
As for black bars, well, you kind of have to decide if you're more bothered by black bars, or by non-integer scaling... I am a little surprised there's not a couple of options for 1440p for overscan area like there is with 1080p.
Working Properly:
720p (Generic 4:3 - 4:3 and Generic 16:9 - 16:9)
768p (Generic 4:3 - 4:3 and Generic 16:9 - 16:9)
1080p fill (DTV 858- 4:3 and Generic 16:9 - 16:9)
1080p over (Generic 4:3- 4:3 and Generic 16:9 - 16:9)
Working Properly with Caveat:
1200p (Generic 4:3 - ~6:4 and Generic 16:9 - 16:9)
Not Working Properly:
480p (DTV 858- 16:9 and Generic 16:9 - 4:3)
1080p under (DTV 858- 4:3 and Generic 16:9 - 4:3)
1440p (Generic 4:3- 16:9 and Generic 16:9 - 16:9)
